Greetings All,
I agree with Jim's pick of the Lab Safety Pocket Guide published by
Genium. We purchase hundreds each year (from Jim) and distribute them
to our students and technicians. Had mixed reviews with Hugh B.
Kareful. Some thought it silly.

Greetings!
Let me begin by saying that I am sending this question to two lists, so I
apologize in advance for multiple listings.
We are starting to get our students to sign a list of rules the professor
has gone over with them. Also, they get a copy to keep, and there are
copies posted in the labs.
My questions are: Is this required? Is this a good idea? Is there a
better way of doing this? How long are you required to keep these
signatures on file?
Any info or help you could offer would be greatly appreciated.

At the Experimental and Applied Chemistry Lab, in the National
University of Mexico UNAM, students sign this kind of "contract" and
teachers keep them for all term or more, if the student failed or
flunked. It has proven to be necessary but still worth it.

Jonathan:
Whether it is required by a governmental agency or not is not the issue. It
is a good idea as it does show that training (of a type) has been done.
From a strictly liability standard, this could help save your facility from
a costly lawsuit if one of these students is injured and it can be shown
that you had gone over the safety rules with them. It won't totally absolve
you of all blame, but it will show you tried to prevent something from
happening.
Giving them a copy is an excellent idea also.
THANKS!

Four students were injured, one seriously, when the denatured
alcohol they were using exploded last week in a Sacramento
nineth grade science class.
The students were experimenting with environmental affects
on lower life forms when one student ignited the alcohol they were
using in a petrie dish. In trying to refill the dish from the one gallon
can, they did not realize that the colorless flame was still buring.
The alcohol supply ignited and exploded setting the students on fire.
If anyone is in the Sacramento area, I would appreciate receiving copies
of newspaper articles about this incident. ... jak

This entire discussion, while well-meaning, and perhaps logical, misses the
issue of liability entirely. Before you implement this type program, before
you ask people to sign such documents, talk to your University Attorney.
There are clear risk exposures connected to this type of documentation.
Review the idea and the materials with legal counsel and then, if you
proceed, follow the terms of the procedure exactly. Make the terms your
"custom and practice".

>Debbie Decker are you out there? (She's at UC Davis)
Yup, I'm here and I'll check the newspapers for any information. The tv
news, in typical tv fashion, couldn't get its story straight. Lots of
arm-waving and finger-pointing and threats of lawsuits. What came from the
tv news said that someone started the fire with a match (a student claimed
that the teacher gave him the match?) and then someone else attempted to
put out the fire with a clear liquid that was alcohol. I'll be back in
touch when I find out more information.
I guess I'd better re-introduce myself, since I've changed my venue. I'm
at UCDavis now, having been lured across the river from CSU Sacramento <g>.
Larger department, good career move for me.

Here at UNE, we have Safety Contracts with our students. They receive lab safety training
to the contract contents and are asked to sign off. We keep them on file for at least the
four years they are with us. I think we still have stuff from six years ago when I started
here.
I have been advised that they will probably not hold up legally, but it shows that
training was conducted and demonstrates a good faith effort on the part of the school. I
think it also shows the students that we take safety seriously and that they need to also.
If anyone would like to see our contract, I can e-mail you a copy. Respond to me at the
address below.
For what its worth, Janeen.

Everyone:
Here is a copy of the agreement we are currently using. We've tried to be
pretty thorough, as these lists of rules have existed before. I would
appreciate any comments/suggestions you might have. Also I would like to
see the safety agreements that others are using, both for comparison and
possibly to steal, I mean share, other ideas. :-)
Note the wording of the contact lens rule. Most of the faculty here want
to keep lenses out of the lab as much as possible, even with the change of
the ACS. But they realize that some students might not have suitable
glasses, so we will allow them for those students, with many warnings,
rules etc.
Also note that students are only required to sign off on the safety rules,
not the etiquette rules. We didn't want the document to get too bogged
down, as the safety rules fit on one page.
Enjoy!
Jon
-------------------
LABORATORY SAFETY
Good laboratory procedure is also safe laboratory procedure.
Your instructor will list any special concerns in the discussion of each
experiment. In addition, there are general operating procedures that must
be followed for all laboratory work:
a. Know the location of the exits, safety shower, eyewash station and
fire extinguisher
b. Wear your approved safety goggles at all times in the laboratory. No
exceptions. No goggles = no lab work.
c. Contact lenses should not be worn in the laboratory. If you must
wear contacts, talk to your instructor regarding special precautions.
d. Keep long hair pulled back or tightly secured. Hair will burn if it
contacts the Bunsen flame. Also, necklaces, loose bracelets, etc. should
not be worn.
e. Do not eat, drink, smoke or apply make-up in the laboratory.
Chemicals in the lab must never be tasted.
f. Spills may be a problem. Wear your heavy duty apron and shoes that
cover your feet completely. Old jeans are good lab clothing; shorts,
cutoffs, skirts, etc. are not.
g. If you have a chemical spill, alert your instructor immediately.
He/she will clean up the spill for you or instruct you on how to do so
safely. Wash off any spilled chemicals immediately, whether on you, your
clothing or the desk top.
h. Please do not sit on the lab benches. Who knows what may have been
spilled there.
i. Hot and cool glassware look the same. Be sure your glassware is cool
before you touch it - or hand it to someone else. Glass also breaks. If
you do break any glassware, alert the instructor; he/she will clean up
the pieces and/or instruct you on how to do so safely.
j. Many chemicals will burn. Flammable vapors tend to flow across the
desk top. Keep flammable liquids and any ignition sources well separated.
k. In the event of fire, back off and call your instructor. Do not
attempt to extinguish the fire yourself.
l. If the building alarm sounds, turn off all apparatus, exit the
building and stay out of the way of emergency personnel.
m. No unauthorized experiments are to be performed and no one is to work
alone in the lab.
n. Immediately report all injuries, no matter how minor, to your instructor.
o. If you have any special health concerns (asthma, allergies, etc.), or
if you are pregnant or become pregnant, inform your instructor. All
information will be kept in strict confidence.
p. Wash your hands immediately after leaving the laboratory. Use the
restrooms down the hall.
I have read and understand these safety rules for lab work and have been
oriented to the safety features of the laboratory.
Signature:_____________________________________ Date:______________
LABORATORY ETIQUETTE
Laboratory work goes more smoothly and efficiently if everyone
adheres to certain simple rules of conduct. Only the most commonly used
glassware and other tools will be in your drawers/boxes. Specialized
equipment, chemicals and solutions will be put out on benches at the side
of the laboratory.
a. Book bags and coats should be placed in the hall lockers. The number
of lockers on the third floor is limited but you will find vacant lockers
on the second floor of this building.
b. If you are unsure of any procedure in the lab, ask the instructor.
Your classmates might provide you with incorrect information.
c. You will most probably be sharing your equipment draw/box with
students from other sections.
1) Check that you have all the listed equipment when you first go
into the lab.
2) Replace all missing or broken equipment.
3) If you break equipment, replace it immediately.
4) At the end of the lab period, clean and put the equipment away.
5) Do not leave your personal goggles/aprons in the drawer/box.
d. Only the listed equipment should be stored in the drawers/boxes. Do
not put equipment or supplies taken from the side benches into the drawers
or boxes.
e. Do not take reagents or other items meant for everyone's use to your
bench.
f. Return all items set out for a particular experiment to the side
bench when the experiment is done.
g. Return all burners, ring stands and clamps to the cabinet where you
found them.
h. Return all burner lighters to the hook by the center sink.
i. Wipe up all spilled chemicals immediately both at your desk, near the
balances and on the side bench.
j. Take only the quantity of chemicals or solutions you need from the
stock reagent bottles on the window bench. Pour them carefully into a dry,
clean and labeled beaker. Do not return unused chemicals or solutions to
the stock bottles.
k. Unused chemicals or products of reactions should be disposed of
following your instructor's directions - usually in labeled waste jars in
one of the hoods.

Did my Masters thesis on Lab Safety and avoiding liability. (ONly got a B- so
I'm not confident of my position)
However, learned of a policy of having students write out safety requirements.
I believe the legal term was holographic evidence. This prevents the claim
that the material was not thoroughly read or understood. That the information
and acknowledgement was a formality that was not binding.
We work in a high school setting. Every student from AP, College Prep and
General track chemistry has his/her own permanent notebook. The first
activity of the year is to "copy" the lab safety policy onto the second page
of the notebook and to sign (parent signature also required) This is a graded
activity (everyone gets an A who completes the assignment. And if you don't,
you're toast)
I guess many feel that it is not very mature, but when we explain the legal
consequences, they seem very cooperative
For what it's worth

Janeen: I'd very much like to see a copy of your Safety Contract. We're
contemplating going the same route with our training/orientation for both
full-time and part-time employees (students, visiting scientists, etc.). Up
til now, this orientation has been left up to individual supervisors, with no
uniformity as to content or expectations. (Not a good policy, I know; but
it's a fact of life.) We're now trying to give some semblance of
organization and continuity to our training program!

Hello all,
I am new to the list so please bear with me if you've seen this question
before.
In our hospital Cytogenetics laboratory they use formamide to make DNA
probes for bone marrow samples. Several steps involving formamide are
required, including the heating in a water bath (at 70C) of formamide
and saline solution. None of this work is carried out in a fumehood.
Recently a technologist suffered a miscarriage which she feels may be
related to her formamide exposure. (I have not conducted any air
sampling as there is no validated method and as well I'm not convinced
that work exposure is the only variable. Miscarriages occur "naturally"
in about 30% of all pregnancies.)
I have asked whether the formamide can be substituted with another
compound and have been told it can't be. Local exhaust to the outside
would be difficult as the lab is in a very old building (c. 1920's) and
ventilation upgrades would be very expensive. I am considering a
portable benchtop local exhaust system but as formamide is a polar
compound, I'm not sure that a charcoal sorbent bed would be able to
capture it. Its vapour pressure is also low, 0.08 mm Hg at 20C so it
appears not to be extremely volatile.
Has anyone any experience in controlling this type of exposure?
Thanks in advance for your help.

HOWDY.
I have had more experience with formaldehyde than I care to recall. We =

First, are you aware of the Formaldehyde standard set by OSHA? If you are =
boiling formaldehyde without a hood, I would bet that you are exceeding =

You have an employee complaint. This is a potentially bad situation. Not =
because she is justified or not, but because there is a standard and you =
do not know what your exposures are. There are OSHA accepted test methods =
for detecting formaldehyde in air samples. We have to monitor on a =
regular basis.
Second, stop boiling formaldehyde=21 You must do this operation in a =
hood. Anyone working near this set up will be exposed to the formaldehyde =
vapors. Formaldehyde, in addition to being a listed carcinogen, is a =
sensitizing agent and can trigger asthmatic attacks that are potentially =
life threatening in sensitive folks.
Third, I have investigated formaldehyde and its risk to pregnancy. We =
have had several students take gross anatomy while pregnant. I have found =
nothing to suggest it causes miscarriage, or birth defects in babies born =
to otherwise healthy mothers. I agree that miscarriage is often an =
unhappy end to pregnancy, and this case is probably unrelated to the =
exposure. It is hard to say definitely since you have no exposure data.
I would suggest that the process is halted until proper ventilation can be =

can be vented.
For what it=27s worth, Janeen.
(Feel free to call me if you would like to discuss further. I take great =
interest in this topic and anything relating to pregnancy in lab settings.)=

We are installing a suite of fume cupboards in a two-storey building near to
an area of busy student pedestrian traffic. To ensure that all would be
well, and that we could confidently make risk assessments of the material we
might exhaust we commissioned atmospheric dispersion studies.
The results we have been given indicated that there will be a one in a
thousand dilution of the stack emission by the time any of the exhaust
reaches ground level.
We have not had a study like this before, but my instinct would have been
that the dilution would have been much greater.
Has anyone got any experience of this or any comments.

The ACS change in policy came after a series of presentations by an
Occupational Opthamologist (ret. Navy), who has investigated chemical
injury reports in several countries. In no case did he find evidence that
a chemical injury had been made worse by contact lenses. Often they were
protective. He ran to earth several accounts of lenses "freezing" to eyes,
etc. Found they were either urban legends, or inaccurate reporting, or
misunderstanding of the medical evidence. There is also the safety factor
that for many people vision correction is much better with contacts.)
Proper PPE was essential for all workers. Also good washing. And prompt
after treatment by an opthamologists. He advocated a type of irrigator
that gently washed under the upper eyelid--not usually reached with an eye
wash fountain.
Sometimes there was eye injury with contact lenses, but usually less than
the same exposure without.

Dear Jim,
re: Exhaust Stack Effluent Dispersion
Several years ago the Chemistry Department here discovered a need to
determine ("map" informally, if you will) the behavior of hood stack
effluent. We are in a single story building with many wings extending
to all points of the compass - Chemistry in the middle. Several benches
and inviting lawn areas exist among these wings and are used frequently
by picnic lunchers (is that a plural noun?) and others taking a break
between classes - very pleasant niches.
Using commercial 40,000 CF smoke generating "bombs" (Superior Signal
Company, New Jersey) we observed (and videotaped) the visible plume from
several hoods and on different days ( different weather).
Any disciple of aerodynamic behavior can tell you about the downward
vortex formed by the wind as it passes the trailing edge of a building's
roof, and our smoke test certainly demonstrated this effect. In most of
the tests we performed, the visible plume rose briefly upward to
dissipate gradually in the air followed immediately by a plume that was
swept directly over the edge of the roof and to the ground. This
oscillation of skyward dispersal followed by groundward (non-?)dispersal
shifted from one to the other approximately 5 to 10 times per MINUTE.
This is a very dynamic phenomenon. None of the videos were able to
show it, but the classic "barrel roll" vortex next to the building was
very evident to all observers on the ground.
My favorite effect was that of running a smoke test in a hood in one
room and seeing a thin but visible smoke plume emitted from the roof
exhaust of the hood in the room next door (second-hand smoke). I will
admit to leaving some windows open in anticipation of this.
Our highly subjective determination of dilution of effluent from the
hoods is very much in the ball park with the 1000 fold dilution
mentioned in the UK study. In some cases, where plumes dived over the
edge of the roof, our dilution estimates were smaller.
One chilling realization I can't escape is that the hood stack effluent
is doing this even when we can't see it. There were occasions when my
nose reminded me that this is true.
We were motivated to do all this during a time when one of our
professors was using phosgene gas as a reagent in an organic synthesis.
Our rough estimates of possible exposures to something as toxic as
phosgene indicated that medical consequences could be had in a few
minutes by someone enjoying a nap on the lawn near the C-wing.
We are not using phosgene any more, for this and other reasons.
If there is a way to mount a short video clip on our website I'll try to
do that. I will notify this group if and when I am successful.
Thanks.

Hello all,
An interesting question from a physical plant engineer today. How do we
handle (remove hazardous materials) from the 125 in-line fans we just
removed from the plenum ventilation system of the Chemistry building? He
suggests HEPA vacuuming them as a solution, as the likelihood of particles
adhering in large quantities to the fan etc at 2500 fpm is remote.
Any experience out there?

Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
Some the research laboratory staff in our chemistry department are most
stubborn about keeping way too many items "stored" on the floor. Safety
cans for acetone, hexane, etc..., glass/pipette receptacles, buckets for
dirty glassware (bench space is too full), glass bottles of chemicals
(usually not combustibles), stir motors, lab jacks, ring stands, boxes of
books, way more chairs and stools than necessary. Extra little tables,
wheeled carts. This surely sounds a bit familiar to some of you.
I'm not looking for advice on minimum walkway requirements or maximum
flammables/combustibles stored outside of approved containers (although
always interested). My concern is with the trip hazards presented by all
this stuff.
My question is - Do you have any policy(ies) that have worked or show
promise, rather than case-by-case assessment? Percentage of
walking/working surface allowed to be occupied by chairs/wastebaskets/plus?
Where do you draw the line? Just how many wastebaskets and glass buckets
and stools do you allow on the floor in a certain sized lab? It would be
great to hear what solutions others have tried or are using.
Thanks.

Linda--Make the requirement to not store items on the floor part of your
Chemical Hygiene Plan. Add the item to your lab inspection form (mine is
based on the CHP). When safety committees do lab inspections they can
ding labs that store items on the floor. If they refuse to comply with the
findings of an audit they are opening themselves up to the disciplinary
process for those that choose to not "fix" items found lacking on the audit;
nasty letter from the Chair or Dean, pressure from senior faculty on the
safety committee, etc.
Perhaps the lab simply needs more storage? Look into providing more
shelving by rearranging some equipment and installing wall-mounted
shelving units. Pehaps a near-by underutilized room can partially be given
over to storage for this lab?
Another tact would be to have your local code official or fire prevention
specialist review the situation and have them explain to the lab staff
why storage of lots of stuff on the floor is not a good idea. I would only
do this if you are on friendly terms with these folks.
Developing a good lab culture in the face of a history of poor lab culture
is the most challenging aspect of our duties as lab safety specialists.
I hope that this is useful information. Tom

I have a logistical problem concerning the performance of lab inspections (I
prefer "reviews" or "audits"). Here at University of North Carolina at
Charlotte we have a very small staff consisting of the Safety Director,
Building Inspector/Trainer, Secretary, and University Industrial Hygienist
(me). As University I.H. I wear many hats: Chemical Hygiene, Radiation
safety, IH, IAQ, etc. etc. etc.
While I am new in this position, it is clear that in order to get through
all the labs in the portion of my time I can devote to this task I will have
to move through each lab fairly quickly. I have developed a checklist,
which is not yet test-driven (attached in MS Word if anyone is interested).
But already there is a clear stumbling block: How does one look at a dozen
shelves holding three hundred bottles of chemicals and come to a reasonable
conclusion as to whether items are stored correctly? While I have had the
usual compliment of chemistry in college, I am not a bench chemist and I am
not capable of looking at a bottle of trimethyl kill-ya-quick and
classifying it as flammable, oxidizer, reactive, acid, highly toxic,
peroxide forming, etc. While I can carefully investigate any given chemical
and come to a conclusion, there are hundreds in each lab and dozens of labs.
The obvious solution is to ask/require lab managers to attach small uniform
labels, supplied by our office, to each bottle. While this proposal is not
being met with a great resistance, I don't expect full compliance anytime
soon, even if it does become carved in stone. Although no one has said it
yet, expected reactions are: "Why should we go to all that effort just to
make it easier for you to police us?" and "The chemicals already meet all
the legal requirements for labeling."
I am interested to hear how others deal with this problem. Comments on my
checklist are also welcome.

Storage in science areas always seems to be a problem. When we renovated a
few years ago there were a couple of things we did to help. First, I would
suggest going through and doing some "spring cleaning". Ask people to get
rid of old, broken equipment and remove any chemicals which are not used on
a regular basis for storage in a stockroom. Second, look at the possibility
of mobile storage units. We purchased several mobile lab carts to match our
lab benches from Kewanee. They are the same height as the benches and the
tops are the same material our lab benches. They roll and have shelves for
storage. They can be placed at the ends of benches to add more lab or desk
space if needed and are used to store various types of equipment which are
often shared between our labs. Most of the time they are stored in the
labs, but occasionally we can temporarily store them in the hallway. Many
of our labs have very little wall space for shelving, so some have added
mobile or free standing wire shelving. As for stools and chairs, only
enough for each student and a couple for professors and lab assistants are
allowed in labs. Often we have them stored upside down on top of the
benches to help with cleaning the floors. All of these things have helped
keep our labs neat and clean. In my opinion, the most important thing is to
clean up every day or two and don't allow people to become pack rats.
We allow 1-2 waste receptacles per lab bench. Any more that show up are
removed when the safety inspection is performed. The same goes for chairs,
carts, etc. Anything stored on the floor must be out of the way of egress
and/or safety equipment (showers, eyewashes, fire extinguishers). In
general, I would say that 80-90% of our floor space stays clear. Although I
initially spent quite a bit of time "removing" things from labs and
informing the person responsible for the stuff as to where it went, most
people began realizing it was easier to keep things neat than to track me
down and find out where it went and now the mess just doesn't happen.
Inforcing people to keep up with the system is where putting this type of
thing on a safety inspection helps. Also, once the initial clean up is
done, it is fairly easy to keep up and I found the professors willing to
help on a daily basis. I made sure that all reorganization was done with
the responsible party's input since they are the ones using the lab and have
to be happy with it. Some have actually thanked me for helping to organize
their labs and indicate that they can find things much more quickly.
I hope these suggestions help. Remember, this will not happen overnight.
It took about 2 years for me to get everyone "on the program" but it is well
worth the effort.

Yes. With Eudora Lite on one computer and even with Eudora Pro 3.0 on
another (both PC clones), although to a lesser extent with Pro, and not for
quite some time. And "kill" is a very apt description. Trashed the index,
lost messages, extremely unpleasant. Had to have assistance deleting the
offending message in the manner you describe.
I haven't found anyone who understands it (or can explain it) completely,
but general consensus is that ATTACHMENTS cause it.
And not just attached Word, Excel, bitmap.... files, but also the
attachments that constitute many email programs' method of attaching
signature files or "business cards."
Another BB I receive repeatedly sends mail to members to NOT SEND
ATTACHMENTS (because of this problem, and I don't think it's just Eudora).
These warnings are repeatedly ignored. Mostly by people who are not aware
that their signatures and business cards are sent as attached files.
Anybody out there have a suggestion or fix??? (Besides switching email
programs.)

I think it is an incompatability problem. I suspect that when the original
message went out, either from the person who wrote the original formamide
message or the server when it bumped it, it included a MSMail return receipt
request. This means that whenever anyone with MSMail opens that message, we
are all going to get that return receipt. Took me a while to figure it out,
and I have MSMail!!! You probably got one from when I opened it yesterday,
too! I guess we all need to be careful of such things in the future. Maybe
Jim Kaufman could try checking the list server for a way to eliminate such
things?!?

This issue cropped up on the SAFETY List several months ago. The newer
versions of Microsoft Mail will automatically attach a file to outgoing
messages that contains formatting codes; this attachment is the one that
generally messes up Eudora and Pegasus programs. Other attachments (not
all due to Microsoft) are the business cards/signature files that are
generated for each message. A third type of attachment is from any
number of software programs (WordPerfect, Excel, MSWord, etc.) that use
various encoding applications. The newer versions of Outlook can also
cause problems when the program is set to automatically reply (such as
for vacation messages). About the only way to solve the problem is for
the SENDER to setup their mail program to send ASCII-type messages and
never, NEVER send an attachment to the whole list. Attach files only
in-line, not as-is (the option on Netscape Mail). Don't send enriched
text (bold, italics, etc.) nor business cards. SAFETY has gone to a
moderated format, which means someone reads each message before
forwarding it to the list, to try to prevent problems such as this.
The downside to the increasing sophistication (read 'more bells and
whistles' ) is that we'll only be seeing more of these problems crop up.

Subject: Re: Chemical storage
Scott,
The checklist you attached is quite thorough but we have found, after
trying several types of checklists, that they are too cumbersome to use
on safety inspections. We inspect labs once a month and obviously they
cannot be thorough. But the purpose of the inspection is constant
awareness and reminders as well as discovering problems that need a fix
such as by maintenance.
We have elected instead to use a simple table that is filled in with
each citation, the lab number or location, the degree of severity or
hazard class. Of the last category we have 3 types-- Major = likely to
cause permanent disability, loss of life/structure/equipment. Serious =
likely to cause serious injury/illness/property damage. Minor = likely
to cause minor injury or nondisruptive property damage. These are
designated A, B, C in that order. Each citation is given a number and at
the next month's meeting, someone has to report that the item was
corrected, is in process, or whatever.
As for storage of chemicals, it is impossible each inspection to examine
every container. We may check a storage cabinet at random. Hazardous
materials such as acids, bases, and flammables are kept in cabinets so
marked beneath the fume hoods, as those cabinets are ventilated into the
hood as well.
One way to approach this type of inspection is to form subteams of 2-3
people who can thoroughly inspect one lab at a time, so that over the
course of a year or two, all labs will have received a close inspection
of chemical storage.
Policing chemical storage is always a problem. A computerized inventory
with receiving dates and proposed disposal dates helps, but there is an
investment in the equipment and software to do so. We have several
yellow flammable storage cabinets and some of the materials were up to
ten years old. I advised everyone that if they wanted to keep anything
in these cabinets, they had to mark them with their name and current
date; otherwise they would be disposed of. I gave them a deadline and
after that I had a lab pack disposal group come in and get rid of a lot
of material. It was expensive but so is storage space and the liability
of outdated materials with deteriorating labels, caps, etc.

As far as being stored correctly, you can normally just ask, "where are the
corrosives stored?", etc. The look on their face will give you the answer.

Policing chemical storage is always a problem. A computerized inventory

MS's new mail system causes two glitches that I know of with newer versions
of Eudora Lite & Pro and sometime Netscape. These occur on both Macs and
Wintel machines.
One is the return receipt. For the most part, it will not allow Eudora and
sometimes Netscape to retrieve mail off of a server and will sometimes
freeze up your system. Of course this doesn't happen with MS mail systems!
The best fix is to go to a server resident system (like Pine via a telnet
function) and delete the offending message. The offending message is
generally the first one in the stack. Hopefully, the Eudora and Netscape
folks will work on a downloadable patch to fix things.
The other one is the automatic reply system. Many people when they're not
going to be answering their mail for a while, set their machine to reply to
all messages sent to them with a response such as "I'll be out of town
until 6/5/98." When the automatic reply message goes out to the sending
listserver, it causes an infinite loop situation. The listserver receives
the automatic reply, sends a confirmation to the automated response
computer, and then the automatic response computer replies again. This
cycle goes on until the listserver has reached saturation or a moderator
intervenes.
My suggestion is that all people using MS mail systems disable the return
receipt function and only send attachments directly to an interested party
or to the listserver's moderator for review before posting. Also, never use
any automatic reply function if you subscribe to a listserver.
I hope this helps those that are having problems.

You can arbitrarily set a disposal date if there is none indicated by
the manufacturer. Obviously you don't want to keep ether around very
long. You can set your own standard such as 3 years from date of receipt
or whatever. If a material is used only once in a rare while, it might
make sense to throw it out and buy more when you need it, rather than
keep it for 20 years in case someone "might" need it. There is a cost to
this but there is also a cost to storage space and deteriorating
containers as well, plus the questionable purity of something that has
been around for many, many years.

This same problem has occured on the SAFETY list and was traced to

Aw, c'mon. 1947's nothing! (OK, I only remember seeing a date back to '36
around here, but I'd be willing to bet there are undated containers going
back further.)
A point of curiosity. Our waste disposal section picked up a
manufacturer's container of
COLUMBIUM OXIDE
once upon a time ago. It was easy enough to find out what name it would go
by nowadays, but I never did pursue the question of when the name of
Columbium was changed to Niobium. And why? From a brief search on the
web, it appears that the name Columbium is still in fairly common use in
areas...
Anybody know a little history on this?

As far as I know, columbium (Cb) still is used in parts of Europe and
elsewhere outside the US - I still see journal articles with Cb in
formulae. I guess we decided to honor Niobe (daughter of Tantalus, whose
namesake has numerous properties and behaviors similar to niobium - the two
occur together geochemically and mineralogically) instead of Columbus's
discovery. Ironically, the principal ore mineral for niobium is columbite
(Fe-Mn-Nb-Ta oxide).
As usual, probably more than you - or anyone - wanted to know.

My mail program appears to have auto-replied to one of the formamide
messages and created the problems everyone has been describing. I am very
sorry for any trouble or inconvenience that it has caused to anyone, but I
can honestly say that it was NOT a message which I consciously sent or a
reply that I intentionally made.
The message I did intentionally post regarding fume cupboards does not
appear to have created this problem, so I assume it was some codes or
return-receipt-request that was in one of the previous formamide messages
that prompted my mailer to act. I do not normally set return receipts or use
attachments because of the problems that others have described with the
"safety" list and also with our UK based haznet list.

Dear Comrades,
It's been a very interesting discussion about the handling of old
chemicals. We recently had an EPA inspection here and the inspectors
found many "old" chemical containers. To decide whether the containers
were hazardous waste, they used the RCRA "discarded" criteria. If a
container did not have adequate labeling or if the container was not in
good shape, they determined that the containers in question were
"discarded" and therefore considered them hazardous waste. Of course,
these containers were therefore improperly stored hazardous waste and were
liable to fines. If the inspectors found a cache of old chemicals in a
specific lab, they would ask the staff present the last time the chemicals
in the cache had been used. If the response was, "Gee, I don't know" or
"Oh, we haven't used that in years", then those chemicals were considered
abandoned and therefore, were hazardous waste and again subject to fines.
The implementation of this "discarded" criteria is a subjective
thing since it seemed to be dependent on the inspector. We have decided
to play it safe and dispose of any chemical that could be considered a
hazardous waste.
I hope this helps.

By definition, a substance does not become waste until declared so by the
user. Your inspectors oversteped their bounds.

Tammy (et al),
I see two global reasons to specify a chemical as too old.
One--> chemical simply looses effectiveness for its intended uses.
Examples:
gradually absorbs atmospheric moisture - no longer anhydrous - Calcium
Chloride and Sodium Hydroxide pellets. Gradually absorbs carbon
dioxide from the air to become a carbonate buffer - Sodium Hydroxide
pellets. Gradually oxidized by atmospheric oxygen to form useless but
otherwise harmless (IMPORTANT DISTINCTION) contaminant - benzaldehyde
to benzoic acid.
This kind of aging is usually of no particular consequence from a Lab
Safety point of view. It may very well be an issue of interest from a
Hazardous Waste Disposal Cost point of view.
Two --> gradually changes (usually oxidizes or spontaneously
rearranges) to form very hazardous (explosive) new materials. This is
the one you need to worry about.
In the latest edition of Prudent Practices ... (1995) there is a good
table on page 56, "Table 3.13 Classes of Chemicals That Can Form
Peroxides Upon Aging". The bottom group ("Class III - ... may explode
without concentration.") on this list are things that I wouldn't want to
handle ( not even open the container) after more than 1 year or so
beyond the receipt date. Note that this means the age here is AT LEAST
1 year at the outside. It's not obvious how long the vendor had it
before he sold it to you. (For those of you without a Prudent
Practices handy these substances are: divinyl ether, divinyl acetylene,
isopropyl ether, vinylidene chloride, potassium metal, potassium amide,
sodium amide). This is where a cordial relationship with your local
bomb disposal unit comes in handy. After 5 to 10 years, my personal
preference is to move diethyl ether into this category also, especially
if it has been redistilled locally to "purify" it and especially if it
is in a glass container and especially if there are visible crystals in
it or on/near the bottle closure. As for such materials from the 40's
and 50's - do you feel Lucky today?
Other materials in Table 3.13 (mostly ethers and alkenes) should not be
concentrated (distilled) without first confirming the absence of organic
peroxides. Two years old is a "rule of thumb" (ask and ye shall
receive) that I use for dealing with these materials. I also usually
suggest 2 years as a guideline for how much inventory to carry (Maximum
= as much as you will consume in 2 years of normal operation).
I know some suppliers include an expiration date on each label.
Sometimes these dates make sense to me and sometimes not. I often have
departments give up for disposal unopened bottles of reagent alcohol
because they are past the expiration date on the labels. I always find
alternate users for such stuff. Just realize that the expiration date
published on the label may or may not be the real answer.
At this point I should apologize for:
a) the length of this reply. Sometimes I just get on a roll.
b) possibly giving the impression that there is a definitive answer to
all this. There isn't. Making decisions like the one you are asking
about is often not a simple matter. You are justified in any feelings
of uncertainty you may have. I have them all the time.
Thanks.

The discussion of old chemicals and placing expiration dates on chemicals
seems to be missing a point. Most chemicals are reasonably stable. If a
higher purity is needed for a reaction, the chemical is purified by an
appropriate physical method. Few chemicals actually require shelf-lives.
The practical matter of addressing chemicals no longer needed is much more
thorny. It has nothing to do with expiration dates; it is a housekeeping
and purchasing problem. If you argue with a chemist that a specific
chemical must be disposed of becuase of a "shelf-life" you will most likely
butt up against a stone wall, since the chemical will be stable.
Argue for increase shelf space in the work area, argue for ordering in the
smallest possible quantity.
Now - having said that - I have a gift for anyone who wants it at the LS&EM
conference. I have 200 very attractive shelf-life posters. These are 14 x
20 inches and are in 4-color. They show a very old can of ether and the
detonation of the can when opened. The posters will be at my display booth
at the conference. Stop by and pick up one.
Before you ask, I cannot mail any, since I am giving these away and have no
way to cover shipping and handling. So, come to LS&EM, and pick up one.

Just don't toss perfectly good KCl, or similar, no matter how old. Lots of
very stable salts out there, which I fear are going to haz waste sites for
no good reason. A lot depends on the purity required, and what is in
bottle; i.e. analytical reagent grade, or better, or not so great

There really isn't a simple way around this problem. Here at Nassau Community

UNIVERSAL SERVICE/E-RATE
PROGRAM IN JEOPARDY
In a nutshell, the universal service, or e-rate,
program, which would provide schools (K-12) and
libraries with discounts from 20 to 90 percent on
telecommunications services (local and long distance
telephone service), Internet access, and internal
wiring is in SERIOUS trouble.
Despite the fact that more than 30,000 applications
have been received, requesting $2.02 billion of the
$2.25 billion allotted for the program in 1998, none
of the money has yet been disbursed to schools and
libraries.
Now Congress is now pressuring the FCC to halt the
collection of funds for the universal service
program, which, in effect, would halt the program
itself until further consideration by Congress.
The Associated Press reports that the request was made
in a letter Thursday to FCC Chairman Bill Kennard from
the ranking members of the Senate and House Commerce
committees, which have jurisdiction over FCC. The
signers were Senators John McCain (R-AZ), and Ernest
Hollings (D-SC) and Representatives Thomas Bliley
(R-VA) and John Dingell (D-MI).
Already, last December, under pressure from Congress
and phone companies, the FCC decided to cut funding
for the Internet discounts and to provide only $625
million in subsidies to schools and libraries for the
first six months of 1998. Previously, as stated
above, the FCC had set the amount at $2.25 billion per
year.
In effect, then, Congress is attempting to rewrite
the Telecommunications Law that it passed in 1996 that
authorized the universal service program and mandated
that telecommunications companies contribute to the
e-rate fund. In the law, Congress attempted to
offset this requirement by removing certain levies
that the companies were previously required to pay.
Now the companies, in particular AT&T and MCI are
balking, and Congress is caving in.
After reading the article below that appeared in
today's Washington Post, WE URGE YOU
TO E-MAIL YOUR SENATORS AND REPRESENTATIVE,
THE FCC, AND TELECOMMUNICATIONS COMPANIES
TO OBJECT STRONGLY TO THIS
LAST-MINUTE ATTEMPT TO HALT THIS VERY
POPULAR AND IMPORTANT PROGRAM.
Ask that the universal service program be implemented
AS IT WAS PASSED BY CONGRESS. Briefly explain why
this program is so important to your students and your
school, your school district, and/or the students of
your area.
THE PROCESS IS SIMPLE.
You can send an e-mail message by going to the "Save
the E-Rate Campaign" site at
http://congress.nw.dc.us/e-rate
The site provides all necessary e-mail addresses and
will copy your message to those groups and individuals
you select.
Note that while the article below states that the FCC
was scheduled to vote on this issue next Monday, the
open meeting has now been canceled in favor of a
Congressional hearing on the matter on WESNESDAY,
June 10.
Pressure from Congress on the FCC is intense. So your
e-mail message will matter and must be sent ASAP.

FCC May Suspend Internet Program
Angry Lawmakers Target Fund Effort
By Mike Mills
Washington Post Staff Writer
Friday, June 5, 1998; Page D01
Facing pressure from key members of
Congress, the Federal Communications
Commission is on the verge of halting
the collection of money for a new
program to help wire schools and
libraries to the Internet, according
to agency sources.
Such a move could end hopes by 30,000
schools and libraries nationwide to
get discounts this year to establish
or upgrade Internet connections. It
also could lead to a reduction in
special surcharges that long-distance
companies have placed on consumer
bills to help finance the discounts.
The fees, running as high as 6
percent on bills from companies such
as AT&T Corp. and MCI Communications
Corp., have angered members of
Congress. The companies, however,
counter that they are necessary to
recoup money that the companies must
pay into a new fund set up to provide
the discounts.
Only a small portion of the fees
actually reach the fund for schools
and libraries. Most of the money goes
toward other programs to ensure
low-cost phone service to rural and
poor areas. The FCC argues that
long-distance carriers should not
impose the fees at all because their
costs have been offset by reductions
the carriers have enjoyed in the
rates they pay to local telephone
companies for beginning and ending
long-distance calls.
The FCC was deluged with calls and
letters yesterday from angry
Republican and Democratic lawmakers,
demanding that the agency stop
collecting money for the program.
The agency "should immediately
suspend further collection of funding
for its schools and libraries
program," said a letter signed by
some of the leading lawmakers on
telecommunications policy -- Rep.
John D. Dingell (D-Mich.), Rep.
Thomas J. Bliley Jr. (R-Va.), Sen.
John McCain (R-Ariz.) and Sen. Ernest
F. Hollings (D-S.C.). "We believe it
is too late for the commission to
rescue itself merely by tinkering
with a fundamentally flawed and
legally suspect program."
The letters are "pretty unambiguous,"
said a FCC staff member, who
requested anonymity. "This removes
any doubt that we'll stop" the
funding, the source said. Before the
barrage from Capitol Hill, the FCC
had been planning early next week to
take less drastic action, such as
reducing funding and ensuring that
the neediest schools get help first.
A spokesman for FCC Chairman William
Kennard said the agency plans to vote
on the issue Monday.
Lynne Bradley, deputy executive
director of the American Library
Association's Washington office,
said: "To call for a halt to this
[program] is a travesty. There are
30,000 applications in the pipeline.
There is clearly a need for this
program."
The program, part of a 1996 overhaul
of telecommunications laws, is being
derided by Republican critics as a
new tax imposed by the Clinton
administration.
Critics said the FCC, with prodding
by the administration, created a
schools and libraries program that
goes far beyond what Congress
intended. The General Accounting
Office found that the FCC exceeded
its authority by creating a Schools
and Libraries Corp. to run the
program.
The FCC has collected about $625
million from long-distance companies
this year and had planned to bring in
as much as $2 billion more by year's
end. So far, however, it has not
disbursed any of the money.

If you receive messages in digest form you get all the messages in one send

I give a safety 'lecture' to all grads and the undergrads beginning
research. During this talk I tell them about not storing things on the
floor, in front of doors, safety showers, etc. Then I tell them that when
they get to their lab to go to the back, close their eyes and imagine
getting to the door or eye wash/shower station without being able to see.
Then look at all the things that they might have fallen over.
Several students have said this exercise really 'opened' their eyes and
they have began cleaning up the floor space.

Dear Mr. Kaufman,
A couple of points which may be useful to add to the pool of knowledge you
undoubtedly have.
I have seen two similiar similiar incidents though not in laboratories.
1/ trying to coax a garden rubbish fire with mineral terpentine from a one
gallon plastic container and similarly the use of white spirit to
coax/accelerate a charcoal barbecue fire. In both cases the container took
off like a rocket spraying the ignited fuel. Fortunately none of this came
in contact with any-body
2/ This is also important. We have bought safety cans franchaised from USA
and manfactured in Australia. On this brand the bottom tap spring is real
strong and many cannot cope with the tap. If you go long this route may I
suggest to consider ones using the plunger pump mechanism or the pour spout.
I can bench press 90 kg. I cannot use the bottom tap of some brands of
safety can and fill a plastic squeeze bottle with say alcohol or acetone.
Hence we are introducing the plunger/pump type and in this case Justrite.
Also to please note to ensure the solvent is compatible with the particular
washers etc.
I hope this is of some use to you
Regards,
Jon Amies

Analytical chemistry -
We have a class for which we teach two different methods of
quantitative analysis for the same element. We want to use AA and one
other method.
We were using copper, and a colorimetric method for the non-AA method.
We switched from analyzing for copper to calcium with the second method
being a titration. We swiched because we felt the use of calcium and
HCl to be more desirable than our use of copper and nitric acid.
The students are having trouble getting good numbers.
Here's my need and my question - Does anyone have a suggestion for a
good reliable, as safe and environmentally friendly as possible, test
method, for an element we can also run on the AA.

This also occurred with a barbecue at my neighbor's house - Two young
boys cooking for themselves when parents were away. Not such a happy
ending as above. The boy holding the can when it blew up had many,
many surgeries following.

While I don't have a good suggestion for you (my lab work ran more towards
blowing things up) I did forward your request on to a women chemists'
bulleting board I subscribe to. There should be some good stuff coming
from them.
I'm getting the hang of things around here. Though the anonymity is kind
of strange - no weird phone calls, brush fires to put out, strange problems
to solve. I'll enjoy it while it lasts! the view is nice - pretty creek
and a nice big cedar tree outside my window <g>.

Since you need nitric acid to run copper properly on an AA, why not go back to that.

As I was writing my message, I feared it may be unclear. Past use was
copper and nitric. Both copper and nitric were eliminated in favor of
calcium and hydrochloric, for safety and waste reasons. Returning to
the use of copper is one option, but we'd prefer to move on to
something altogether new.
I should also mention that a suspected problem with the calcium results
may be linked to upsets or over-demands on the deionizing system. If
we were analyzing for something pretty much nil in tap water, that
problem would go away also. We have considered zinc analysis, but
didn't care for some of the reagents needed for the colorimetric method.

Are you using an ionization suppressor, i.e. La chloride? AA measures
absorption of light at a particular wave length by the neutral atom in the
flame, Ca is very easily ionized and the ionized atoms don't absorb. It
is at least an explanation of the scatter in the student's results.

You could try silica, by flame AAS using N2O/C2H2 Vs colourimetric
(molybdenum blue)
or Ferrous iron by AAS Vs Titrimetric with dichromate or cerric sulfate, or
permangantae, or colourimetric using 1,10 phenanthroline. Or Chromium
determination by AAS N2O/C2H2 vs titrimetry with ammonium ferrous sulfate,
or Barium by AAS N2O/C2H2 vsgravimetric with sodium sulfate, or Magnesium
AAS vs gravimetric as ammonium magnesium phosphate, or titrimetric by EDTA
, etc etc
Look in Vogel's Textbook of Quantitative Inorganic Analysis, ISBN 0 582
46321 1, or APHA Standard methods for the examination of water and
wastewater, or other standard analtical texts
E-mail me for other suggestons if these do not suit your lab capabilities

Fundamentals of Analytical Chemistry by Skoog, West, and Holler
gives the outline of a good colorimetric method for testing for
Fe (II) in natural water (page 882 of my text). Iron (II) forms
a red-orange complex with orthophenanthroline. A second
colorimetric method for determing manganese in steel is also
given. This method is probably less desirable due to the need
for dissolving the steel. You should have little trouble locating
a copy of the above text. If you can't find the text, let me know
and I will send you a photocopy of the methods.

We use two methods for iron. One is a coloremetric method (Spec20) using a
permanganate solution and then an AA method.
We have also done Chloride by ISE electrode and gravimetric titration using
silver nitrate but you may not want the hassle of reclaming all the silver
or disposing of the AgCl and excess silver nitrate.
We have thought of analyzing Mg by AA and also EDTA titration. As someone
mentioned earlier you will want to use Lanthanum oxide to get good AA
results.

It was in a Sacramento, CA high school. Three students were
observing the effects of alcohol on some lower animals. One of them lite
a match. The worse injury was 3rd degree burns to the face and hands; I
believe there was also some lung damage -- he was taken to a burn center.
The other two received less sever burns and were released from the
hospital the day of the accident. Have not seen anything about if or
when the more seriously burned student was/has been released.
The investigation is trying to find out where the matches came
from.

The discussion about analytical methods raises some issues
about the focus of the LABSAFETY-L list. We want to
encourage breadth in its use while remaining true to our mission.
Are there some health and safety issues surrounding the choice
of methods and instrumentation?
On some occasions, we may want to have the responses sent
direct to the original poster with a summary back to the list at
the end. I am not suggesting that I think this is one of those
occasions. Rather, I am raising the matter in response to an
off line inquiry I received to stimulate some thought and discussion

Is there anyone who would say no ? Health and safety are two of the
four reasons I posed the question to the list. The other two reasons
are (1) environmental concerns and (2) control of costs in the other
three areas.
I have another question to ponder, if there is interest. As a CHO, are
a lot of your duties tied to environmental responsibilities, or do
other employees take on those duties?

Dear colleagues:
I am planning on taking the CHO certification exam offered by the NRCC in
Boston in August. I would like to ask the group for advice on good study
materials. Also, hearing from someone who has recently completed this exam
would be helpful. Of course, all replies should be direct to me personally
and I will forward a summary, if wanted.
Thanks in advance,

I have to say I agree with Janeen. One possible miscommunication is the
meaning of "environmental" for some CHO's it may mean the working
environment. For most it should mean (in addition) the world environment.
I find it hard to believe that one can be ensuring compliance with OSHA,
EPA, etc and not have some thoughts regarding the environment enter into the
equation. One of the nice things about lists such as these is the fact that
one _can_ pick lots of peoples brains about better ways to handle something.
Whether that means a more environmentally sound method or one that is
personally safer really doesn't matter. Part of LabSafety is the safety of
the individuals who work there and who also (probably) reside in the
vicinity. That is their environment and they are affected by everything
that goes (gets dumped) into it!

YES! discussions must be open so all persons may participate...otherwise
you do not get the entire story. I am responsible for Health, Safety,
Environmental AND Quality Issues where I work. All of these are directly
interrelated. Many companies have tried to separate them out but crossover
issues constantly arise. Indeed, even OSHA & EPA have crossover
responsibilities. There is a book distributed by American Society for
Quality (ASQ) entitled "QUALITY, SAFETY, AND ENVIRONMENT...Synergy in the
21st Century" which examines this concept thoroughly.
I would agree with Jim, however, that often an issue should be pointed
towards an offlist discussion (perhaps Yahoo CHAT!, an electronic bulletin
board, or some other venue). Otherwise, the email messages can overwhelm a
person who cannot POSSIBLY get through all of them in a day. Jim...do you
have a suggestion of where?

The email I'm receiving from the LABSAFETY List Server has problems. Quite
a few messages are "hanging up" and will not let me download any messages
after the "hung up" one.
I'm writing this on the blind, because I've not received any incoming
email since last thursday. So far I've had to ask the compter techs to
delete 3 "hung up" emails. And, I'm still getting more of them ...
The computer techs on campus would like to know if the problems I'm having
with email from the LABSAFETY List Server are:
1) originating from the list server
2) originating from the campus server
3) or, is it Eudora with the problem ?
Can anyone figure out what's happening? Your thoughts ...?

In general the NFPA diamond is designed for information to firemen and
other emergency responders. As such it is designed to inform on relative
fire risk, dangerous reactivities, as to water, for example, and ACUTE
health effects.
Make sure your students understand that it is not the best guide for
laboratory reagent hazards as they are likely to be used. JT Baker has one
widely used guide, as does Malinkrodt. Unfortunately they are very
different--some years ago there was a big flap about copywrites on the
systems, much to the detrement of the lab chemists, and to benefit of lawyers.
Anyone have an update on that flap.

Since Mallinckrodt and Baker are now subsidiaries of each other, the flap
may have gone away. I looked through my Baker catalog and their web site,
and cannot find any information on the labelling system everyone talks about.
Mallinckrodt's system (LabGuard Labeling System) is listed in their
catalog. It separates chemicals by hazard class (Flammable, Health,
Corrosive, Reactive, Incompatible or None).
Is this adequate for a chemical lab or storeroom? We are establishing a
University wide labeling system for chemical storage and would like to know
what the 'big boys and girls' are using.
If anyone has info on the Baker system, please forward it.

Baker catalog (97-98) lists 0-4 hazard ratings for health, flam, reac,
contact and recommended storage color for each individual product entry.

We are not big but we use a combination of Baker, Fisher, Mallinkrodt,
et. al. in categorizing chemicals for stockroom storage.
> If anyone has info on the Baker system, please forward it.
Join their Chemical Care Program (if it still exists). They will send
you posters, handouts, and workbook that explains their system and lists
ratings and storage colors for all their products. Sorry, I don't have
a point of contact handy. Try customer service.

I can't leave this one alone. One of my nerves has been hit:
Chemical storage schemes should be organized around the inventory's
ability to react with itself - the ability of one chemical to react
unpleasantly with on or more of the other materials in the inventory.
Using this criterion, I would take steps to separate as much as
possible:
-- oxidizers from the oxidizable (all organics)
-- strong mineral acids from strong bases
-- acid reactive materials (cyanides, sulfides, Mg, Zn, etc.) from all
acids
-- This scheme goes on ... you get the idea. (Note: What you see
printed here so far is not sufficient.)
My point? "Health Hazard" or "Toxic" is not a chemical property and
should not be one of the pigeon holes used to categorize materials for
compatible chemical storage. With few exceptions, I see them all as
health hazards. I'm not sure how to address the category called
"Incompatible". Each one is incompatible with SOMETHING.
I first threw this fit a few years ago when I discovered J. T. Baker's
storage scheme with the colored labels, etc. They, too, had a category
called "Toxic". I discovered a number of combinations that I ( and
Prudent Practices...) would call incompatible that JTB had lumped
together as Toxic materials.
There was also inconsistency with the colors used by JTB and other
chemical giants with similar compatible color schemes. Was the
development of color scheme storage intended for use by chemists who
don't know much chemistry? Were the color schemes developed by
someone in "Techincal Support" or by someone in "Marketing" at the
offices of the 'big boys and girls'? I have been ignoring the color
schemes of the 'big boys and girls' for a long time now. Maybe they
have changed - I don't know.
My suggestion is to get someone who is conversant in chemical reactions
and (especially) NOMENCLATURE, to look at each chemical name and assign
it a storage class with a written label attached to the bottle(s).
A decent guide ( if not a list of your storage categories) can be found
in Prudent Practices ... , 1995 edition, on page 54, Table 3.10.
Thank you for listening.

IN an industrial R&D lab, we have organics, inorganics, flammables, corrosive acids,
and corrosove bases. Works for us.

Used the Flinn system over Baker. More detailed and was better able to
handle some of those pesky compatibility issues that the simple Baker or
Mallinckrodt systems won't.
Don't have my Flinn catalog - it's walked off somewhere. Could someone
help with a phone number? I'd heard they were getting ready to mount a
website?

I think Michael deserves a round of applause and a seal of approval for
taking on this project on his own. He is to be commended for being
proactive and helping to make his workplace safer for himself, his
co-workers and his students. Would that more chemistry professors thought
like you do!!! Good luck, don't get discouraged, pass safety-sense on to
your students!!!

Hi Gang,
We used to buy really nice acetone wash bottles, made by Nalgene, which
had the NFPA diamond in color printed on them. The only problem with
them was that they would dribble on the bench top when they got warm-
like for example when the sun shone on them.
The last time we ordered from Fisher, they sent us some made in Engand,
also with NFPA but not in color. Generally not as nice.
So we called Nalgene- they said they are redesigning because of the
tendancy to dribble. The English ones also dribble. maybe that's not a
problem in England.
I never thought the dribble was a big problem- you just loosen the screw
top and it doesn't do it.
Thoughts? Suggestions? I really don't want generic bottles with hand
labels on them- they smear and run with the acetone and become
unreadable very quickly. I'm thinking we are going to get something
with a vent in it which won't work well for rinsing dishes.

I have been designing (re-designing) a compatible storage plan for
chemical inventory. I'm updating our CHP. According Prudent
Practices ... (Table 3.10) inorganic cyanides need to be kept separate
from acids AND from strong bases. The acid mixture I know about.
A search through several chemistry texts, Bretherick's book, and through
Sax has not revealed to me the chemical consequences of a cyanide +
hydroxide mixture. What am I missing?
I'm not adverse to following the advice of a recognized source of
wisdom, but I am curious to know what the chemical reaction is that I am
avoiding by keeping cyanides away from strong bases.
Are there any ideas out there?
Thanks.

I did a lot of work with NaCN. It's stable, except it very slowly reacts
with CO2 in the air to generate HCN. But that is very slow. NaOH can be
used to scrub HCN.
I guess I come out the same as you- should be OK with base.

I thought that was odd, too. Our resident chemist in charge of hazwaste
pointed out that CN compounds may be shipped in alkali; we couldn't find
any nasty CN-strong base reactions listed either. Our chemist did point
out that the EPA states that CN waste shouldn't be exposed to pH < 2 or >
12.5 (actually, the document stated BETWEEN 2 and 12.5, but we figured that
was an error).

You can dispose of liquid cyanide waste by mixing with sodium hypochlroite
(Liquid pool chlorine) or with potassium permanganate solution. The cyanide
is oxidised to cyanate which is much safer. This then hydrolises to ammonia
and CO2 slowly in alkaline conditions.

Hi NACHO Members....
With so many new members this past month, I thought it
might be a good time to announce again the existance of
a NACHO Steering Committee.
The Steering Committee is open to all members who would
like to work on the growth and development of the Association.
Currently there are about a dozen members. You are welcome
to be part of this Committee if you are interested.
In previous planning discussions the Committee came up with
the following goals and mission statement for the Association.
Your comments and suggestions are welcome. This is a good
time since we are heading into our first public meeting in less than
two weeks.
If you are interested in joining the Steering Committee, please
express your interest directly to me (labsafe@aol.com). ... jim

I don't know about other states, but in California, if I were to do the
above at my place of employment, I would be treating hazardous waste
without a permit to do so.
Has anyone heard what's up with the laboratory reform proposals
submitted to the Ca. Dept. of Toxic Substances in 1996? I heard in Jan
of 1997 that we would soon get the green light to implement the 12
accepted proposals (one of which was being able to bench-top treat
waste).

What about making the "treatment" the LAST STEP of a procedure which
generates the "waste?" I am not completely sure, but I don't think that is
considered "treatment" if the substance you're treating is not yet
officially "waste."

I also am in California, and there is some wiggle room. Point one
is that it isn't a waste until the generator declares it a waste, and
point two is that if the mixing sodium hyprchlorite with liquid cyanide is
part of your written procedure it is part of your procedure and is not
treatment. Treatment occures when you collect it in a special contaminer
(which you labeled waste), and then as a separate, unrelated, activity to
the chemical process one adds a chemical to the waste so as to change the
hazardous nature of the waste.
This approach is legally more defensible if it is someone else who
added those additional steps to the procedure (harder to argue that you
put it in just to avoid being a waste generator). Also it would make a
much stronger legal argument that this is the "standard procedure" if such
steps were routinely included in books of standard methods, but I haven't
seen any where it is done.
If you decided to go this route, it would be a good idea to run it
past your legal staff and see if they buy off on the argument. There are
gray areas, and it would be best to have them committed to the concept
before hand and not after the fact.

At least we seem to have some degree of sanity with the rgulations in
Australia.
One would assume that if a company has a licence to use hazardous chemicals
responsibly then they would have the expertise to treat the waste products
according to an agreed procedure. The volume of waste produced in our case
is very small compared to an industrial process or mine.
Maybe you could classify the "waste treatment" as "hazard reduction"
(even
though we chemists understand it is oxidation ). Alternatively call it
"modification of reaction products" after all it is not really waste
product until you need to dispose of it.
You could justify the step as being necessary under your duty of care.

Justification in our own minds does not mean the EPA will smile. The
very most difficult part of my employment is having to help people
understand that we don't get to oppose the law just because we don't
agree with it. If we all had the same opinion, we wouldn't need
elections. Poor laws need revision, not violation.

In response to the question," Has DTSC responded to the Laboratory
Reform Task Force?" ---
I was briefly involved with the Laboratory Safety Alliance when we were
wrestling with the idea of benchtop treatment and other laboratory
issues of interest to the Department of Toxic Substances Control (DTSC).
A list of proposed laboratory procedures and proposed regulatory
"options" were drawn up by the Laboratory Regulatory Reform Task Force
(in which DTSC participated) and, yes, there is a response (if not
conclusion)from DTSC. You can see it in all its glory at the following
website --- http://www.calepa.ca.gov/dtsc/txhwlrtf.htm
In a nutshell, benchtop treatment is legal in California if:
* the treatment is done by the person generating the waste.
* the treatment is done in a laboratory and (my interpretation) in the
SAME laboratory where the waste was generated.
* the treatment is done as a batch (not in-line process) and the maximum
batch size and treatment methods are as described in Prudent Practices.
* the treatment occurs with 10 working days after the end of the
procedure.
*there are a couple of other chemical common sense items too.
The good news is that benchtop waste treatment is California is legal
under certain conditions. The bad news may be in the conditions.
Prudent Practices describes waste treatment for about 18 categories of
compounds. The procedure for acid-base reactions is quite
uncomplicated, as one might expect. The procedures for almost
everything else are much more than most experimenters would approach
with glee. The one for cyanide treatment reads, "An aqueous solution
of the cyanide salt in an ice-cooled, three-necked flask equipped with a
stirrer, thermometer, and dropping funnel is cooled to 4 to 10 deg. C.
A 50% excess of bleach is added slowly the stirring ..."
I have other concerns about what Prudent Practices has to say where the
treated residue should go (in the case of treated cyanide), but DTSC
said is was OK. Right? I wonder how much excess hypochlorite it takes
to qualify as hazardous waste. I wonder how much cyanate it takes to
qualify as hazardous waste.
(These are some of the little things that bring joy and uncertainty into
the lives of CHO's everywhere. I'll stop driving us crazy now.)
Thanks for asking.

Cleaning up after a colleagues retirement brings a question
Found many bottles of HCl in an acid cabinet (Wood and plastic construction)
along with a single unopened bottle of nitric. The HCl bottles were covered
with a gritty brown deposit on all horizontal surfaces (cap and bottle
shoulder) The substance looked like rust, but again, there is no metal in the
cabinet (just the door hinge wire and maybe an exposed screw head or two) The
brown material did not wipe off dry, the plastic safety coating on the glass
had become sticky and discolored from the material. It almost felt greasy.
Alconox and hot water did not clean very well, lots of brush and sponge
scrubbing was needed. Even then, the plastic was permanently discolored,
almost in a splashed pattern. Some of the HCl bottles had 20 yr old delivery
dates.
The nitric acid bottle had almost none of these characteristics
Any suggestions as to the nature of this material and the cause?
Thanks in advance

It sounds too much like it was in a metal cabinet at one time. Could it
have been in a metal cabinet and then moved into a newer non-metal
cabinet later without cleaning the bottle? I've seen this before.

along with a single unopened bottle of nitric. The HCl bottles were
covered
with a gritty brown deposit on all horizontal surfaces (cap and bottle
shoulder) The substance looked like rust, but again, there is no metal
in the
cabinet (just the door hinge wire and maybe an exposed screw head or
two) The
brown material did not wipe off dry, the plastic safety coating on the
glass
had become sticky and discolored from the material. It almost felt
greasy.
Alconox and hot water did not clean very well, lots of brush and sponge
scrubbing was needed. Even then, the plastic was permanently discolored,
almost in a splashed pattern. Some of the HCl bottles had 20 yr old
delivery
dates.
The nitric acid bottle had almost none of these characteristics
Any suggestions as to the nature of this material and the cause?
Thanks in advance

FYI - since we talked about what was the status of the LRRTF
recommendations a few days ago..... DTSC accepted 10 or 12 of 14 (maybe
Mary Ann can help me with the numbers here), then said that it was not up
to Toxics to do anything about it. So, it has been left to the California
Legislature to codify and direct implementation of the recommendations.
In our Standards Work Group meeting this morning, AB 2424 (Ackerman -
California State Assembly) and AB 2698 (Ducheny) were discussed. These
bills will implement a portion of the LRRTF recommendations as applied to
onsite treatment. AB 2424 is currently with the Policy Committee - letters
would probably help to move it out. See
www.calepa.ca.gov/dtsc/leghot98.htm for more information. There are also
some proposed changes to the hazardous waste regulations (waste oil,
alkaline batteries, fees, etc.) that those of you in California should take
a look at.

We have had your chemical chygiene plan for about a year now.

Yes. We call them inspections and we have a annual review of the written
program that involves the faculty members who are involved with the hygiene
plan.
> 3 . What , exactly , is addressed in the annual audits ?
This year, our audit is very basic. I will preform a monthly inspection
that is in our chemical hygiene plan and is available at:
http://www.bgsu.edu/offices/envhs/self.htm
The reason that it is the basic monthly inspection is to develop a trust
level with faculty. Our department's intension is to help them provide a
safe place to work and conduct research and not to police them. The
inspection should be called a advisory inspection. The responsibilty for
providing a safe and healthy lab environment rests on the faculty member or
principal investigator of a lab and we try to help them to do that. If I
do notice a serious safety or health hazard, I do bring it up, but my main
goal is to develope a trust level with researchers. I notify them what the
inspection will look at and I give them a time when to expect me.
> 4 . What should be addressed in a chemical hygiene audit ?
I think the specifics depend on the University/College/School that you are
at. Each will have more important issues than others. The main idea of
ours is to begin looking at health and safety concerns of the labs. In the
future, it will grow to be more then just that and address specific issues.
> 5 . What level of management should recieve or review the audit
reports
>?
Currently, the person responsible for the lab gets a report with a copy to
the department chair. Any more administrative levels that would get the
report may not know what to do about it. If there was a serious health and
safety concern that was not addressed at the chair level, then it should go
to the next level. Try solving the problem before reporting it to upper
administration. That is key to an effective program.

The National Association of Chemical Hygiene Officers Association
held it's first ever public meeting this evening at the Sheraton Imperial
in Durham, North Carolina. Fifty CHO's and folks interested in lab
safety attended.
The group spent two hours discussing the future of the organization,
consuming pizza and soda/beer compliments of Kaufman & Associates,
and enjoying the opportunity to visit with each other. The meeting was
held in conjunction with the LS&EM'98 Conference.
The discussion of the organization's future focused on whether to try
to do more than function as a virtual association through the
Labsafety-l discussion list. The clear concensus was to continue the
current path and try to add a web site as soon as possible.
Concern was expressed that there is currently no recogition of life
experience in the criterial for seeking NRCC CHO certification.
The only vote taken was to decide whether or not to notify Pat Hamm
that the pizza had arrive. Pat was waiting in the front lobby to lead
the Pizza Hut delivery people to our meeting room. Meeting
convener Kaufman cast the tie breaking vote and Keith Krohn
volunteer to save Pat (the second time today).
The next public meeting will be held in January at the New Safety '99
meeting. Stay tuned. A NACHO breakfast will again be held at the
ACS national meeting on monday, August 24th. Location to be

10. WETTERHAHN LABORATORY POISONING CASE: FINAL MEDICAL REPORT
In the spring of 1997, the science community, and in particular
the chemistry community, was saddened to learn of the tragic
death of Karen E. Wetterhahn, age 48, a professor of chemistry
(Dartmouth College, US) and a noted researcher on the effects of
heavy metals in biological systems. Wetterhahn died of
dimethylmercury poisoning as the result of the accidental
spillage of a few drops of the chemical on her latex glove-
covered hand. The accident occurred on August 14, 1996, and the
poisoning produced progressive destruction of Wetterhahn's
nervous system, until she finally died 10 months later. Before
she lapsed into a vegetative state, Karen Wetterhahn requested
that her case be presented to the general medical community, to
scientists working with mercury, and to toxicologists, in the
hope of improving the recognition, treatment, and prevention of
future cases of mercury poisoning. The full medical case report
of the illness, death, and autopsy of Karen E. Wetterhahn has now
been published. Nierenberg et al (9 authors at 2 installations,
US), the authors of the report, make the following points: 1)
Dimethylmercury is lethal at a dose of approximately 400 mg of
mercury (equivalent to a few drops, or approximately 5 mg per
kilogram of body weight. It is classified as a "supertoxic"
chemical. 2) Records suggest that Wetterhahn handled dimethyl-
mercury on only one day, while wearing latex gloves and working
under a ventilated hood designed to prevent exposure to chemical
fumes. She had delayed but ultimately fatal neurotoxic effects
similar to those caused by methylmercury compounds, and this case
illustrates the potent toxicity of dimethylmercury and the need
for additional safety precautions if it is to be used in any
scientific research. 2) Five months after the accident, on
January 20, 1997, Wetterhahn was admitted to the university
medical center with a 5 day history of progressive deterioration
in balance, gait, and speech. She had lost 15 lb over a period of
2 months, and had experienced several brief episodes of nausea,
diarrhea, and abdominal discomfort. 3) Wetterhahn recalled that
in August 1996, while transferring liquid dimethylmercury from a
container to a capillary tube, she spilled several drops from the
tip of the pipette onto the back of her gloved hand. She reported
that she had cleaned up the spill and then removed the protective
gloves. (The date of the accident was established from her
notebooks and other laboratory data to be August 14, 1996.) 4) On
February 6th, 22 days after the first neurologic symptoms
developed (and 176 days after exposure), Wetterhahn became
unresponsive to all visual, verbal, and light-touch stimuli. 5)
The authors report they could find only 3 previously reported
cases of poisoning with dimethylmercury, all of which were fatal,
and that equally bleak outcomes had been reported in patients
with severe methylmercury poisoning. In view of the dismal
prognosis, and after more than 3 months of aggressive treatment
and support, Wetterhahn's advance directives were followed, and
she died peacefully on June 8, 1998, 298 days after exposure. 6)
Some anatomical findings from the autopsy report: "The cortex of
the cerebral hemispheres was diffusely thinned, to 3 mm. The
visual cortex around the calcarine fissure was grossly gliotic,
as was the superior surface of the superior temporal gyri. The
cerebellum showed diffuse atrophy of both vermal and hemispheric
folia. Microscopical study showed extensive neuronal loss and
gliosis bilaterally within the primary visual and auditory
cortices, with milder loss of neurons and gliosis in the motor
and sensory cortices. There was widespread loss of cerebellar
granular-cell neurons, Purkinje cells, and basket-cell neurons,
with evidence of loss of parallel fibers in the molecular
layer... An extensive high mercury content was found in the
frontal lobe and visual cortex, liver, and kidney cortex. The
mercury content of the brain was approximately 6 times that of
whole blood at the time of death... 7) The authors conclude:
"Dimethylmercury appears to be so dangerous that scientists
should use less toxic mercury compounds whenever possible. Since
dimethylmercury is a "supertoxic" chemical that can quickly
permeate common latex gloves and form a toxic vapor after a
spill, its synthesis, transportation, and use by scientists
should be kept to a minimum, and it should be handled only with
extreme caution and with the use of rigorous protective
measures."

Related Background:
DEATH OF PROMINENT CHEMIST PROMPTS CALL FOR CHANGE IN NMR METHODS
The international chemistry community was shocked recently by the
death of Karen E. Wetterhahn, age 48, Professor of Chemistry at
Dartmouth College (NH US). Wetterhahn was a well-known authority
on the effects of heavy metals on biological systems. Ten months
ago, in the course of calibrating a nuclear magnetic resonance
(NMR) apparatus with the standard dimethylmercury, Wetterhahn
accidentally spilled a few drops of the substance on her latex-
covered hand. Unexpectedly, the substance penetrated the glove,
and within a few months the first neurological symptoms of
mercury poisoning appeared. She died on June 8th. John Winn, head
of the Dartmouth Chemistry Department, and others, have now
called for the chemical community to establish an NMR standard
safer than dimethylmercury.

LabSafety Folks,
We are in the process of purchasing a 400MHZ NMR for our new Science
Facility. The safety section of the sight planning document gives
some very basic info on keeping people out of the 5 Gauss zone but
that is about it. Do any of you have suggestions for finding info on
safety and electromagnetic fields - or personal experience? How are
areas like this handles in the CHP?
Also, the manufacturer has indicated that the instrument does not
need to be on emergency power but we have heard horror stories about
the cost of starting up the magnet again if it goes down. Any
experience, advise?

The only people truly at risk from an NMR megnet would be those with
pacemakers. Everyone else just needs to remove their wallet both to
protect their credit cards from demagnetization and to minimize the amount
of dollars which these things tend to suck up.
The magnet does not require electricity to run because it is superconducting.
A UPS is still a good idea to minimize damage to the electronics during
power failures.

Depending on the size of the magnet and manufacturing, the cost to restart
a quenched magnet could be $10,000. Also, a quenched magnet will never be
as good as before, so you can lose stability of the instrument.

Couple of things. Make sure you check the rooms next to the magnet. It can mess up
instrumentation
through a wall. Also do some training, if for no other reason, to teach people to leave
their credit
cards in their offices. These NMRs really play havoc with those magnetic strips.

I heard on the radio this morning that the NIH panel on EMR has released
their findings. Apparently they are saying there may actually be a link
between exposure to EMF and medical problems. Haven't seen the actual

I also believe they were more addressing the issue of high power lines, too.

Prudent Practices just states in the dark and under nitrogen. Check to see
if the chloroform is stabilized - 0.75% of alcohol is typical and provides
good protection against formation of phosgene.

What do you think are the pros and cons of keeping them in a locked

Hi Cynthia,
Did you get enough responses? Here are some more. As you can see there are
lots of varied items thrown out to a simple request. I am going out on a limb
and figure you are getting a Bruker, with an Oxford magnet. The person that
installs the instrument will most likely be a Ph.D. in Chemistry or Physics.
When installed he/she will most likely have a training day for all users. The
person who will be maintaining Liq. He and Liq. N2 should help with the
installation, stay close to the installer, look, listen, and learn.
The suggestion of an UPS on the system may not be practical as there is a lot
more power consumed than a PC. We had Northern Technologies, an UPS and power
conditioner manufacture, price us a suitable UPS, nearly $10,000 for a 20
minute backup. Remember, though our system is 1991 vintage, and power
consumption for the controller may be less now.
The installer of our machine put a red/white stripe strip at the 5 gauss point,
in our case 5 foot radial axis. He put a large sign warning for people who
have pacemakers, and neural implants, metal implants in bones, and etc. at the
entrance door. Much of the safety issues will most likely be gone over by the
manufacturer's installer. Read the preliminary site preparation manual that
you most likely have received, ours had much info on safety issues.
I personally do not believe that we will ever find any conclusive evidence as
to ElectroMagnetic field effects on human physiology, except in an extreme
field, much larger that 10 or 20 gauss.
Lastly, Dr. Switzer is wrong on the issue of a quench, his statement is true
only if there is damage to the magnet core. We quenched last year, $6000.00 to
restart, but we are getting better results now. We apparently had not gotten a
really good tune during installation.
Good Luck

If you don't use them, why would you want to keep them?? Unless the cost
of disposal is a problem, I'd get rid of them.

The phosgene is generated in the chloroform by the incidence of light
rather than by the heat. Refrigeration helps as long as the container
is keeped in the dark.

Kay:
You probably aren't going to like this but here goes <weak grin>:
Since the containers are partly used, surplusing them to another source is
not an option (no one will want an open container). And if you aren't
going to use them anymore, why keep them and leave the problem for someone
else to clean up?
Bite the bullet, Kay, and dispose of them with a haz waste firm. Gonna
cost you some dollars but it'll be taken care of. The price will only go
up with time.
If you need some info about waste firms, e-mail me privately.
Good luck,

If these items are truly not going to be used in the foreseeable future,
then all they become now are accidents and spills just waiting to happen.
It's best to dispose of them. No locked cabinet stays locked forever;
you'll need to include them every year in your chemical inventory update
(saving every little bit of work helps); and the mercury compounds (even
as a "stable" compound like mercuric chloride) offers some risk of
elemental mercury vapor and becomes a trickier cleanup should the
bottle break.

I don't have my references at hand, and it's been more than a few years,
but roughly it goes like this:
R-Cl destroys or at least temporarily use up or inactivate the liver
enzymes responsible for metabolizing ethanol.
In industry there is the well known degreaser's flush, when those working
with certain solverts stop for a pint after work. Some other solvents,
such as those used in autobody shops will have a similar effect.

Subject: photodecomposition of bromoform

Is it safe to assume that bromoform photodecomposes to carbonyl
bromide just like chloroform photodecomposes to carbonyl chloride
(phosgene)? I couldn't find anything on carbonyl bromide toxicity -- less,
same, or worse than phosgene. I did find reference in Merck Index that
bromoform can be stabilized with several percent alcohol and should be
stored in the dark which sounds like chloroform.
The reason I raise this issue is that bromoform is used by
geologists use it as a heavy liquid for density separations of minerals;
there could be some very old bottles of it in the back of a mineralogy lab.

Sorry it took me so long to respond; I'm only in the office a couple of
days a week in the summer.
The scheme came from the Nov. 1991 issue of Journal of Chemical Education
(vol 68, no. 11, p. 942). "A Short Qualitative Analysis Scheme without
Hazardous Wastes", by John T. Petty.
We made a couple of minor modifications, such as making sure the solution
is basic before testing for nickel, and using ammonium thiocyanate and
1-pentanol in place of 1-nitroso-2-naphthol when testing for cobalt.
Basically, though, the scheme works great and can be completed in about 3
hours. We have the students test known solutions of the ions one week and
do an unknown the second week.

Question that still comes to mind is how do you students know if they have
lead, chromium, silver, etc.? Seems to me, that what we are looking at are
qual schemes for innocuous metals, but the ones used in industry are not
being addressed?
Wouldn't it be much more instructive to incorporate the testing and problems
with DISPOSAL in a class setting.
