You make an excellent point: the frequent confusion of pet. ether and
diethyl ether, the peroxide former. Also confused, when translating from
common to chemical names are benzene and benzin, otherwise called petrol or
naptha; and dioxane, a useful solvent and peroxide former, and dioxin, an
infamous environmental contaminate, otherwise known as TCDD. Both are
toxic and carcinogenic (the former only suspect c.), the later much more so.
But you probably knew all this--didn't you, everyone.

I came late to this discussion but: There is an NFPA (704) labeling
diamond with numbers 0-4. Primarily things with a 3 or 4 rating by this
system are highly flammable. However if the inspector is talking about
CLASS 1 then he is talking abour materials with a Flash Point of less
that 100 F and they should be in a cabinet. Especially 1A materials with
a flash of < 73 F. Look in OSHA 29 CFR1910.106 for limits for storage.

Greetings,
Our hazardous waste haulers told me recently that an empty diethyl
ether can is not a problem. Even if peroxides are present and there is
a reaction , when it is opened it is only a small "pop". They danger,
they say, is when there is ether left in the can and the "pop" ignites
the flammable ether. I have no direct knowledge on this one but it
seems to make sense. Not that I'd open one myself.
> I discovered a near empty 5 lb can of diethyl ether - no one will
touch it.
Sodium azide, of course, is a acutely toxic chemical and "P"
listed chemical is one is going to dispose of it. It is not a hazard
to anyone inside a closed bottle.
Can't address the concerns over uranyl nitrate and uranium oxide.

Diethyl ether comes from the manufactures
with a peroxide inhibitor already present. Most
if not all manufacturers add BHT (butylated
hydroxy toluene) as the inhibitor. I have also
been told that the iron in the metal containers
acts as an additional inhibitor.
With diethyl ether, peroxides only reach
explosive levels upon concentration. This means
that much of the ether must be allowed to evaporate
after the peroxides have already formed for a
problem to exist. For example, I recently came
across a 4 liter glass bottle of diethyl ether
that was manufactured in 1972. Little of the
original material had been used, so the bottle
had probably only been opened a few times since
1972. The bottle was soaked under water for a
week by our hazardous materials group
to dissolve any possible peroxides hiding
under the cap. Once the bottle was finally opened,
no peroxides were found to be present. This does
not mean that I recommend that just anyone open bottles
of old ether. Only trained experts should be trusted
with such dangerous procedures. Two excellent references
are given below.

Let me be the first to welcome you to the first edition of the NACHO Chips =
newsletter. The name was suggested by one of our members. Each issue =
will contain Chips of information gleaned from the list server and =
submissions from our members.
This said, we hope that NACHO Chips will become a valued resource for =
NACHO members. It is a forum for the exchange of information to assist =
CHOs in their daily activities. In this issue, you will find an opening =
article about NACHO and how to join, the latest information on contact use =
in the labs, training presentation tips, how CHOs are compensated and the =
variations on how the job duties are assigned, as well as a sketch of the =
different work places CHOs find themselves serving.
It is my hope that you will continue to share ideas and send items of =
interest to me for publication in future issues. NACHO Chips is here for =

The founding of NACHO.
The National Association of Chemical Hygiene Officers (NACHO)
was created in Jan =2798 as a virtual association. NACHO is the
professional organization of CHOs. =20
NACHO was created to support, promote, and advance the chemical=20
hygiene officer and laboratory safety. It brings together CHOs and=20
other people interested in lab safety/chp/cho issues. =20
Today, nearly 500 people are sharing ideas, information, and resources
on an internet discussion list, LABSAFETY*L. Together, they are the
beginning of an association which adds strength to the CHO and those
who would encourage and promote health and safety in laboratories=20
throughout the world.
Tomorrow, the National Association of Chemical Hygiene Officer will
become what its members make it. The first public meeting will be
held in Raleigh*Durham, North Carolina on Wednesday evening June
24th from 6*9 p.m. in conjunction with LS&EM =2798. Join us.
For more information about NACHO, contact Jim Kaufman, President of

ACS Ok*s Contact Lenses
Jim Kaufman reports the American Chemical Society Joint Board/Council
Committee on Chemical Safety voted this morning at
the national meeting in Dallas to remove it=27s prohibition
against the wearing of contact lenses in labs.
The next issue of =22Safety in Academic Chemistry
Laboratories=22 will have a new statement which endorses
the use of contact lenses when all other appropriate forms
of eye protection are used.=20
The question was raised on the list as to why the ACS changed its policy =
and what evidence was used to support the policy change.
Dr. Kaufman responded with the following:
Members of the ACS Joint/Board Council Committee on
Chemical Safety have been investigating the issue for the past
five years (not a group to take precipitous action=21). The efforts
were coordinated by Eileen Segal (EBSEGAL=40AOL.COM).
Eileen published her finding in 1995 and 1997 (may/june issue)
of Chemical Health and Safety. The evidence and reasons were
laid out fairly concisely in those two articles. In short, most of
the arguments raised in the past were found to be unsubstantiated
rumors and conjecture.

SURVEY OF THE MONTH
Health and Safety Pledge
This modest proposal is somewhere between Jonathan Swift and
Mark Twain who said.... =22Humor is the lighter side of truth.=22
I think it=27s time to build an honor roll of college and university =
Presidents
who are willing to sign the =22Health and Safety Pledge=22....
=22At our institution, you will not have a job and not be a student unless
you are willing to follow recognized good practice and obey the laws of
health, safety, and environmental protection.=22
Could an academic institution achieve a significant strategic advantage
or simply shoot itself in the foot?
Would something of this nature assist you as CHOs for colleges and =
universities in your attempts to build compliance? Do you have something =
like this already in place? If so, has it helped?
Please respond to Janeen Lapierre directly at JLaPierre=40MAILBOX.une.edu
Results will appear in the next issue of the NACHO Chips.

TRAINING TIP OF THE MONTH
Using the Darwin Awards in Laboratory Safety Training
=20
I spend quite a bit of time presenting laboratory safety training to our =
new scientific staff, and I am always looking for ways to make it more =
interesting and memorable. Discussion of the Darwin Awards has been a =
successful way to capture the researchers=27 attention and to help focus =
on the practical importance of safety awareness. It also introduces a bit =
of humor into safety training =21
Here=27s the a definition of the Darwin Awards concept, followed by their =
website address: =22Following the ideas of Charles Darwin, the Darwin =
Awards are given, usually posthumously, to the individual(s) who remove =
themselves from the gene pool in the most spectacular fashion. However =
there is an exception to the requirement to die. If said individual does =
not die, however does render him/her self incapable of producing any =
children * they may be eligible for the dubious honor of receiving the =
award while still alive.=22=20
Darwin Awards Website (http://www.officialdarwinawards.com)
At the end of each Laboratory Safety training session, I ask if my =
audience has heard of the Darwin Awards, then get one of the scientists to =
recount their favorite one; if they haven=27t heard of the awards, I tell =
them a few of my favorites.
We start off with a simple one, like the man who tipped a Coke machine
in order to get a free coke, it fell over on him and crushed him to =
death...he had several =24 and change in his pocket at the time of his =
demise... Most folks think, THAT will never happen to me, it is too =

=20
So, next we discuss one about a fellow who was a little more intelligent...=
...This guy was clever enough to figure out how to steal a jet assisted =

enough to figure out how to attach it to his car and wire an ignition =
switch to his dashboard. He took his car out onto a long stretch of =
highway in the desert, a safe place to enjoy the ride and away he went. =
The wreckage from his vehicle was found smashed into the side of a cliff a =
few miles away.......
=20
I like to ask questions like these after introducing the Darwin Awards...
What safety awareness was lacking in these incidents? What did these folks =
forget to consider?? Would a different attitude towards safety/risk have =
changed these scenarios??
Then...How can you incorporate safety awareness into your research? =
Connecting this concept directly to their day to day experiences, I ask =
them to think about the Darwin Award concept before they do their next new =
experiment.....What is the worst possible thing that could happen if =
everything in your experiment went wrong????? and are you prepared??? What =
could happen that could make you look really ignorant, or that could =
injure you or those in your lab???
Using the Darwin Awards as a tool to introduce safety awareness has
helped increase participation by our scientists in the Laboratory Safety =
training program. While this segment takes only 5*10 minutes out of our =
three hour laboratory safety training session; it has been a useful way =
to make connections between the safety staff and our researchers. After =
almost every lab safety training session, I have a person or two who =
lingers to tell me a story of some fire, incident, etc..that they observed =
or heard of from a friend while they were in graduate school or at another =
industrial position. I use these stories to liven up subsequent safety =
training sessions., in addition to the Darwin Awards.

I know that we're always looking for anecdotes for safety training. This
one just happened to me on Friday at work:

I was oxidizing organic material dissolved in water to carbon dioxide and
collecting the gas in a tertiary amine liquid scintillation cocktail for C-14
concentration determination. The apparatus is a standard flask, with
condensing arm, addition funnel, and a cold trap between the flask and
liquid scintillation cocktail to prevent any water carry over into the
cocktail. The entire apparatus is pressurized in order to get a steady
flow of the CO2 produced in the reaction to the LSC. The cold trap is an
ice/ethanol bath, about -10 C. My oxidant for the water is "Van-Slyke
Folsch" solution, essentially chromic acid. (Chromium trioxide dissolved
in 20% sulfuric acid/phosphoric acid mixture. Works REAL good!) This
oxidant is boiled with the sample (water) to make the reaction work a
little faster.
Apparently an ice crystal formed in the cold trap thus creating the
ubiquitous "closed system." About 16 mintues into a 25 minute experiment,
the tygon tube carring the pressurized carrier gas (10 psig/100 ml/min)
ruptured, thus bathing the entire fume hood which enclosed the experiment
in a beautiful orange liquid. The lovely fountain of chromic acid which
spewed forth easily reached the top of the fume hood and then dripped down.
I checked for ice crystal formation 2 experiments prior to the event, and
there were none in the system.
Lessons learned:
(1) Engineered safeguards can and do work. (I consider hoods an engineered
safeguard, even though the operator has to turn them on.) The sash was
pulled down on the hood to about my chest level, (I'm 6 foot tall) and not
a single drop of the chromic acid was sprayed outside the hood. Everything
was set at least 6" into the hood, which I am sure helped prevent spraying
the room, since most of the top portion of the sash was sprayed.
(2) Ice can form quickly between experiments. Historically, I usually
check every three or four experiments because the condenser is very
efficient for drying the gas produced. Check more often.
(3) PV=nRT is for real. I've personally tested it Friday. Heating closed
systems will can be problems!
No one was in the room at the time. I was about 15 feet away when I heard
the "swoooosh" of the rapid depressurization. Clean-up took most of the
morning with the usual jeers from my collegues about Boyle's and Charles' Law.
There ya go! One more for the books!

We test them at a couple of opening heights to determine if there are
oddities, and we sticker them at the side of the sash with a label that
points to the sash height at which the reported average face velocity
(written on the sticker) was measured. We educate VAV hood users on the
matter of "this is the height at which the reported AFV was measured and
when you move the sash around it may change some..." I believe that at the
request of users we have put a couple of stickers on, reporting the
measured AFV at two sash heights. It seems that most of our VAV hoods are
stickered somewhere around 14 - 18 inches.

I asked one of our planners a similar question several years ago, and at
that time he answered with some confidence that his nearest reckoning for
the expense of throwing away gobs of conditioned/tempered air was
$1/cfm/year. (E.g. a 4-foot hood pulling 100 linear fpm through an 18 inch
opening is sucking out about 600 cfms; run it that way all year and it
costs $600.) We are in rural "mid-north" Indiana, if that helps compare
energy costs. I don't have data handy.

On page 181 of "Prudent Practices" it says 80-100 fpm if the system is
properly designed. The implication is that this is at the sash height used
for normal operations.

Greetings:
Please educate me. I thought that Variable Air Volume (VAV) was a
dynamic system that adjusted the face velocity to ~100 fmp at any
height the sash is at. Some systems responded faster like the Phenix
system reacts within seconds. What is going on? I'm confused.

There are some VAV hoods that do a very good job of keeping the face
velocity fairly constant over most heights of the sash, but our experience
is that they are not at all perfect. Many VAV units, especially older
ones, do not have face velocity sensors and rely entirely on a cable
attached to the sash to close and open a damper. The volume of exhausted
air is decreased, for example, when the sash is pulled down, but we do not
count on it being in *exact* proportion to the height decrease.

About 12 or 15 years ago, an energy=conservation technician
labelled all the fume hoods on campus with a fluorescent sticker
that said something to the effect "This hood consumes $700 in
energy per year. Please turn off when not being used". Most of
these stickers are still on the hoods, believe it or not.
So factor in inflation and you can see that a hood eats a lot of
warm/cold air. None of our hoods use cold make-up air; they all
exhaust the conditioned room air.
P.S. The stickers work - people DO turn off hoods now.

That depends on your job description and your employer's vision of what
you're suppose to do. By the regulation, the CHO is reponsible for the
implementation and "maintenance" of the Chemical Hygiene Plan. Your
employer may require you to develop and maintain the Hazard Communication
Plan for your facility as well.

Hello Desi.
I enjoyed our chat the other day. =20
As far as haz com is concerned, it is a standard in and of itself. As CHO =
you may be asked to do job hazard assessments which will in turn let you =
know who will require this training. Folks in your facilities department =
are likely candidates. Until you have a chemical hygiene plan then the =
lab personnel will fall under this standard too.=20
The CHO is responsible for putting together Chemical Hygiene plans for =
labs and implementing the training associated with the CHP. The Lab =
Standard is very specific as to what it expects from a CHO. This said, =
your institution probably has a much broader view of what they want from =
you. =20
As you are in the discussion phase of CHO at your school, be sure to ask =
what they expect from you. I have never been required to do haz com for =
facilities unless they were working in one of my areas. Then I would give =
them lab safety training and haz com for the stuff in the direct area they =
would be working in. This is very different from going into the shop area =
and determining what hazards are there and training for that stuff.
Hope this is helpful, Janeen

Jeff,
I'll deal with question 2 as we only have constant volume bypass
hoods at our facility.
Last June, Landis & Staefa provided several _excellent_ laboratory
ventillation seminars in Maryland. According to Greg DeLuga P.E. (Landis
and Staefa) annual fume hood operational costs is between $3 - $5 per
CFM per Year. We found the $4 figure to pretty much account for our
fume hood costs based on the average CFMs determined during our annual
hood surveys.
You may be best off contacting the individual hood manufacturers to
see what the current cost/cfm/year they are using to sell their hoods in
your area. Their figures may better reflect your local electric service
rates.
Hope this helps!
Linda

We are in the process of re-evaluating our fume hood certification SOP.

2) Also, can anyone provide a rule of thumb or a reference a method to
find the HVAC cost of conditioning a cubic foot of air?
Thanks for your help,
Jeff

I guess this may sound like a silly question, but how much peroxide is
acceptable in a "pure" chemical? We have been testing our organics for
peroxides for a while now, and the turnover seems rather high. In fact, one
bottle of 2-pentanone tested contaminated when we opened it upon receipt
from the manufacturer! I contacted Aldrich, the manufacturer, and they said
that they don't have a standard for peroxide levels, so they didn't see a
problem. These chemicals are used an unknowns in our organic labs, so they
are used in a lot of "wet testing" (iodoform, schiffs test, sodium test,
solubility testing), physical properties tests (bp, refractive index,
density) and spectroscopy (IR, FTIR, NMR). Some of the instructors have the
students distill the unknown as a way of finding the boiling point. I have
tried to get them to stop this, as microscale distillations (frequently)
accidentally go to dry. Also, they tend to oxidize some of the aldehydes we
use. Suggestions?

samples for mineral analysis. We cannot substitute HF for another reagent.
We carry calcium Gluconate gell in our first aid kits and we train our
staff in the dangers and safety requirements for handling HF.
Our current volume is 2 to 5 litres per day
At present we are using an Optifix teflon dispenser from 2.5 litre bottles.
The dispenser is held in a sink inside the fume hood (to prevent syphoning)
and operators are required to wear full protective clothing including PVC
apron, PVC sleeves, rubber gloves, face shield and safety glasses.
We believe this is the best method available.
There have been instances where the dispenser leaks (weeps) around the
seals, and changing from one empty bottle to a new one poses the risk of
droplet splash or drip.
Does anyone else know of a better system of dispensing HF?

Dear Colleagues--Yes, they are <italic>supposed </italic>to adjust the
face velocity
to the set point (usually 100 l.f.p.m.). This doesn't always happen.
As with all electronic devices there is some drift over time in the
setpoints of various parameters for the operation of the boxes, valves
fans and other components under the integrated control of the VAV
control device. Many VAV systems are rather sophisticated (read as
many different components) and keeping all of the hardware in control
is easier said than done in some cases. It is important that the VAV
functions of each hood are checked on at lease an annual basis. We
determine face velocity at 6" (three points), raise the sash to full
open
and do a 2nd face velocity. The 6" and full open readings should be
within
20 % of the set point, although, realistically, the 6" readings are
often too high (c. 150-200 l.f.p.m.) to be within the 20% range.
We have a criteria that when the sash is raised up that the face
velocity
should return to the set point criteria in a minute or less.
I hope this is useful information. Tom
P.S.: Face velocity is not indicative of capture. We use the dry ice
protocol along with face velocity to determine the functionalily of
a fume hood.

It looks like you did a lot of things right. For additional safety
awareness, see if you can persuade the network to make available a copy of
last week's episode which includes a patient brought to ER after an HF
spill. Not too far off the mark for a "drama".
Did anyone else out there watch that episode? Pretty well done, I thought,
although I would have given him another half day to expire, but then
another nurse would have been on duty.

Hi there:
Martin: It sounds like you're doing alot right - 2 to 5 liters a day
of HF - that's a pretty scary amount. Having an outside expert or
someone else in your organization, not involved with the process,
review the procedure on a regular basis may be a good way to root out
complacency and familiarity. Familiarity, of course, breeds contempt
and spawns accidents.

I was pretty impressed that it was so accurate. I watched it with my
hubby who was fairly wide-eyed when I started telling him some of the
more horrible HF stories in my repetoire. I would've given him a few
more days to expire too but the rest was close to the mark.

Greetings all,
I have two sources that, I think are saying different things. Any
opinions? Bretherick's Handbook of Reactive Chemical Hazards says:
(p1150) " Nitric acid methanol in concentrations >10% is not
recommended. At best it is completely unpredictable approximation to
a nitric acid-alcohol rocket propulsion system."..."It also form the
explosive ester, methyl nitrate. Hawley's Condensed Chemical
Dictionary, says, "Methyl nitrate Deviation: By reaction of nitric
acid and methanol in the presence or urea."
My problem. Students use a solution they call 'Nital' formula 5%
nitric 95% methanol but some bright grad students decided more is
better. Are these darlings making rocket fuel?
I was first told of this when they were concerned that the solution was
boiling on it's own. Our waste hauler dressed up in their bomb outfits
to dilute it before they would take it. I have been asked to write a
safety protocol for it's continued use. I've got a protocol JUST WANT
TO KNOW ABOUT THE CHEMISTRY. Thanks in advance.

I saw it and was looking for technical/psuedotechnical information on the
treatment. When the man was brought in, Dr. Green mentioned treatment with
Calcium ?, but I missed it. Was it Calcium gluconate?...something else?
I also missed the the part about how the man was exposed and how much/type
of exposure there was. I figure it must have been a large container
explosion.
As for how much time the man lived, if exposure was more than dermal, such
as inhalation of vapor, the time they gave him was probably reasonable.

I think I mentioned that Dr. Miguel Trevi=F1o, HF expert, will be giving a
free seminar on medical management of HF exposure, this Fri, in Austin
(anyone who's nearby is welcome - we even have a few coming from St.
Louis). Dr. Trevi=F1o said that the ER episode has made him somewhat of a
celebrity.
There'll be a fair-sized (i.e., too big to fax, and it probably wouldn't
come out too well anyway) handout to go along with his presentation. If
anyone would like a copy of the handout, which I haven't seen yet, please
contact me off-line - be sure to include a mailing address.

They did not use Calcium gluconate in the ER episode. I believe they said
Calcium chloride.

Hello everyone. I am putting some training material together for employees
regrading useful information on a MSDS. I would like you to review the
following section of it and tell me what you think. Is it accurate?
"Vapor Pressure, Vapor Density, and Evaporation Rate. Chemicals with high
vapor pressures (greater than 1 atmosphere) evaporate quickly. Low vapor
pressure compounds do not. Chemical vapors will rise when the vapor
density is less than 1 and will go to the floor when greater than 1. High
vapor pressure chemicals with a vapor density less than 1 present an
inhalation hazard. Heavier chemicals concentrate in low places, creating
fire, explosion, or health hazards."
If you see a problem with it please let me know directly. Thanks for your
help.

I agree with Janeen's reply, but at the same time, air currents (open door,
open window, ceiling exhaust, etc.) could easily mix dense, potentially
flammable, chemical fumes to create a potentially explosive mixture. Density
alone does not determine whether a gas/vapor mixes with the ambient
atmosphere. Physical conditions within the room may actually be more
important!

As I visited with my ophthamologist yesterday (during an exam--my aging
eyes need bifocals), we discussed contact lens use when working with
chemicals. I related the new stance that ACS is taking on the use of
contact lenses. He told me that just two months ago, he treated a
fellow who had lime blown into his face and eyes. The eyes swelled,
creating the need for the ophthamologist to remove the contact lenses.
Dr. Pheneger told me that when he removed the contact lens, it took a
layer of tissue off the eye. But, he also said that the layer of tissue
was a much more minor issue than an alkali burn to the eye. Thus, he
felt that the contact had actually helped protect the eye (relatively
speaking). He didn't feel it was worth publishing, but thought it was a
related anecdote.
Just one more story to help support ACS's new stand.

Get your hands on the Lab Standard, 21 CFR part 1910.1450. IN the
definitions, it says:" " Chemical Hygiene Officer" means an employee who
is designated by the employeer, and who is qualified by training or
experience, to provide technical guidance iin the development and
implementation of the provisions of the Chemical Hygiene Plan." (bold my
addition) "Training or experience" seems pretty clear.
I think Jim said you can download a copy from the OSHA.org site.

A third party account by me;
My brother was part of a day's pay maintenance team at a petro-chemical
refinery. As they were cutting through a plugged line with a hacksaw the
line eventually ruptured (suprise!). Fortunately he had stopped a few
moments earlier and all three of them moved their face shields from the
elevated position to the protective position. None of the three had their
safety glasses on.
His accounts of the treatment with calcium (gluconate I presume) indicate a
significant of pain is involved. These three were quite fortunate the line
did not rupture earlier. Ironically, they had just repaired another section
of the same line downstream. Needless to say the supervisor was extremely
embarassed by his letting the safety of PPE slide.
This was a particularly embarassing story for my brother as I had finished
my graduate work in Industrial Hygiene a few months prior. Needless to say,
the safety person and his brother have had any discussion about safety is
more important than production. Think I'm one up on him at least! There
are other incidents but that's another ...

Response to the offer of HF handouts has been a bit more than I expected (>
20 and counting). Not a problem, but it would make things much easier if
you could provide your address in a format that I can readily copy and
paste into a mailing-label format. Please include your name, and you might
want to leave off the alphabet soup. This may seem minor, but multiply it
by 20-30 and you get the idea.
I should be able to send out the copies next week.

Desi,
Did you say Physical Education? Yipes.
It would be pretty unlikely that too many folks will go on record with
CHO-horror stories. Since the whole thing is an invention (a good one) of
regulators, to admit them might cause problems.
However, there is information out there to help you prove your point. One
of our articles in Chemical Health & Safety, (May/June 1997, page 10) is
entitled "What every CHO must know." Too be honest, just about anything
published in the magazine falls under that category. There is a new CHO
certification process thru the National Registry in Clinical Chemistry and
you'd better believe those exams cover chemistry- lots of chemistry.
Contact Gilbert Smith 202-393-7140 or NRCC6@aol.com and have him send you
info regarding what the test covers. Lastly, you can download the standard
itself from www.osha-slc.gov under standards, go to 29 CFR 1910.1450. If
you want more info, contact me directly-
good luck!

Being in the UK I thought we would be a very long time waiting to see the HF
episode, so I was quite amazed when it was shown last night (Thursday 8th).
I don't regularly watch it too closely, so my wife was very surprised at my
accurate predictions of what was going to happen - she did not know I have
the advantage of all the collective wisdom out there!

Content-Type: text/plain; charset="us-ascii"
As many of you know, I am involved in an effort to develop a Project XL in
cooperation with the EPA around the issue of the application of RCRA to
laboratories (details are available at http://esf.uvm.edu/labxl). One of
the challenges we have faced in this effort is that the EPA is a very
diverse audience of people, who have a wide variety of perspectives
relative to regulatory issues. For example, some are strictly concerned
about enforcement issues and legal concerns around how regulations are
implemented, while are others are more hands-on and concerned with how
particular regulations might be implemented in practice in order to
encourage pollution prevention.
As a result of this, we have developed a number of lines of argument about
the need for RCRA reform as is it applies to laboratories. So far, we have
developed physically-based, socially-based and regulatorily-based
arguments. These have made a significant impression on the EPA, but there
are still some people who question the need for a new regulatory scheme,
given the expense this implies for re-writing regulations and re-training
inspectors and other enforcement officials with regard to the new scheme.
We would like to develop another argument, based on the need for parity in
the way the regulations are applied to laboratories. We are aware of
various instances where very different inspection results have occured
depending on which inspector or agency was conducting the RCRA inspection.
We are trying to compile a list of these instances to help the agency
understand the degree of variability we perceive in the way RCRA is applied
to labs and thus the need for a clearer standard for application to
laboratories.
So, if your institution has a history of RCRA inspections of laboratories,
we would be interested in a brief listing of:
the date of inspection,
the number of labs covered,
the agency inspecting and
the outcome, in terms of the number of violations found and the amount of
any fine.
While this information is publiclly available, we are in a bit of a hurry
for it and gathering and organizing it into a form suitable for our
purposes is likely to be time-consuming. Sending the information directly
to me is preferred; I will compile the results and make them available on
the Lab-XL web page.
Thanks for any help with this.

I, too, have had experience with nitration mixtures. Several years ago
the chemistry department here made p-chloronitrobenzene from
chlorobenzene. Here are a couple of appropriate anecdotes:
1. The purification step involved recrystallizing from reagent alcohol.
The occasional student would vacuum filter the recrystallized product
(in ethanol) using the same buchner funnel and flask still containing
the nitration mixture filtered after the synthesis step. Forgetting to
empty and clean the filter flask between uses usually caused the
apparatus to erupt, sending the buchner funnel and most of the flask
contents ( 50/50 nitric and sulfuric acids previously diluted to ca. 20%
strength with ice water PLUS the recently added ethanol) a couple of
feet into the air. Miraculously, no major catastrophes resulted. The
procedure was changed when the pattern became obvious after a few of
these.
2. During the time the original procedure was being used, waste bottles
of the nitration mixture were routinely seen to be bubbling
spontaneously. It is my unconfirmed suspicion that an amount of
alcohol found its way into the waste bottle intended for the nitration
mixture. This, too, was abated when the procedure was changed.
(I make no claim of truth or fantasy to the rumor that this is related
to the fact that the bulk of the students in this survey organic course
were majoring in disciplines other than Science or Engineering.)
As to the dependability of your two references: I put my money on
Bretherick. This reference is highly empirical, very extensive, and
thoroughly documented. Hawleys is also a very fine reference; it just
has a different sort of pedegree. Hawleys works well if you are
merely wondering what "methyl nitrate deviation" means. Bretherick
will give you a list of those who have blown up a laboratory doing it.
I think your "darlings" may indeed be making rocket fuel (or close to it
much of the time). Their report of the boiling mixture is a wake-up
call. I applaud the caution of your waste hauler. I think your
students need to find another way to their desired end rather than
contining toward their undesired end.
Good Luck.

Hello Stephen,
At our location we use scanned images that are indexed in an Oracle database and linked to our chemical inventory. We communicate with the server using a telnet connection on a distributed network. Scanned images can be faxed to any fax machine. In the near future we will upgrade (?) to graphical user interface developed using Powerbuilder and run in Windows 95 or NT. We have over 65,000 chemicals so this creates a full time job for someone to scan and enter these into the database. Overall it is an expensive solution but has the advantage of getting MSDSs from the manufacturer for the specific chemical/mixture. I can put you in contact with the developers from Argonne National Laboratory if you would like more details. Another solution might be to try a commercial MSDS application like the package Envirowin Software, Inc. advertises. You can reach them at (800) 454-0404 or www.envirowin.com - I don't know the quality of their database but they advertise it contains ove!

I am working for the VA Med Center in Washington, DC, and we need an
automated, easy-to-use MSDS management system. I am interested in your recommendations, warnings, thoughts, endorsements, and condemnations.
We are currently running two networks:
1)VMS on an alpha Dec Server with terminals, and
2)PC network running Windows NT
The MSDS system will in all likelihood run on the PC Network.
We are thinking that Scanning images of MSDSs with a limited #

All thoughts will be appreciated.

This has been a big issue in health care for several years. Many of the
latex allergies begin as sensitivities to the powder (commonly corn starch
plus or minus other ingredients) in the gloves. As the wearer's hands
became irritated, the latex worsened the irritation, leading to latex
sensitivity (in a miinority of cases, but there're lots of users). It's
the employers responsibility to provide non-allergenic PPE , but it's the
employee's responsibility to demonstrate sensitivity to standard PPE. Some
employers (hospitals in particular seem to specialize in this) make this a
very difficult process.
Two tidbits:
1) If you're allergic to tropical oils and fruits (e.g., palm oil,
bananas), odds are fairly high that you will develop a latex allergy fairly
easily (remember, latex comes from tropical plants).
2) People with spina bifida commonly have allergies to tropical oils and
fruits, and latex. This can lead to anaphylactic (i.e., life-threatening)
reactions when touched by health-care providers wearing latex gloves, or
just by using IV tubing with latex injection ports. Extreme cases react to
powder generated by someone donning latex gloves in the same room.
Nitrile is nice!

Good points. For non-latex gloves, blowing into them before use may reveal
perforations (the again, maybe not); thicker fingertips (gloves, that is)
may work, too. Maybe the best solution is to use a higher grade of latex
gloves when latex is appropriate. I'm guessing that the FDA is looking at
the cheaper gloves that have more natural rubber and thus more sensitizing
proteins. It's worth noting that latex gloves do poorly with many common
organic chemicals, too (most ketones, many alcohols, aldehydes - including
crotonaldehyde, chloroform, B-T-X, hexanes, etc.), although butyl rubber
works well with most aldehydes, alcohols, and ketones. How appropriate a
choice is latex for chemicals found in most labs?
I agree in principle that chemical protection should take precedence, but
people with latex sensitivity shouldn't have to choose between causes of
hand discomfort. The irritation is not only, well, irritating, but also
degrades the integrity of the skin, thus enhancing said skin's owner to
exposure to pathogens and chemicals. Moreover, as sensitization tends to
be a cumulative process, each exposure (i.e., glove use) may increse
discomfort and/or increase the likelihood of future allergic reactions.
There's a nice little compilation of compatibility info in a spiral bound
handbook: "Quick Selection Guide to Chemical Protective Clothing" (K.
Forsberg & S. Z. Mansdorf, Van Nostrand Rheinhold, ISBN 0-442-02377-4).
The 3rd edition came out at the end of 1997, and lists compatibilities of
16 different barrier materials against 600 chemicals. It lists for ~ $25 -
I just put at least one in every lab building. It's handy to use before a
procedure or when ordering chemicals (order PPE at the same time!).
No easy answers.

We evaluated a half dozen programs that supposedly allow you to scan in
your MSDSs and retrieve them electronically. We selected a program called
SCAN WIZARD. The program was formally sold by Eclipse Software, but
ownership recently changed. The new company is called SafeTec Software
(360/573-2929). SafeTec will scan in your MSDSs for you (for a price, of
course).
Before purchase we obtained demo copies from each company. Several of the
products would not work on our system. I highly recommend that you try a
demo before plunging in with a purchase.
We run the system on Windows NT 4.0. We have been scanning MSDSs in
furiously for most of this year and now have about 7,000 in the system,
which is about 40% of what we expect to be the final number. To supplement
this program, we purchased the Sigma/Aldrich/Fluka and Fisher/ACROS
compendiums of MSDSs on CD ROM. Otherwise we would have more than twice as
many MSDSs to scan in. The program is written using a version of Microsoft
ACCESS.

It's my understanding that the apparent allergy to the corn starch is
really an allergy to latex particles carried on the starch. But the
problem with co-workers being affected by others removing their gloves is a
real one.

I loved this! But, I have to bring everyone down again. What is called in
lay terms a calorie is actually a kilocalorie in dietetic or scientific
terms (i.e. a 300 calorie candy bar is actually 300 kilocalories).
Therefore, only 6 kcals have been pulled from the body fat for that first
example and you can figure the rest. Sorry to burst the humor bubble. I
will still be sending this to my fellow nutrition students.

Subject: Liability Concerns
Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
A recent discussion I had with a campus Chemical Hygiene Committee member
promted a question regarding individual liability.
Does an individual's personal liability in regards to possible litigation
increase as a result of being named to a Safety Committee?
In this case, our campus committee is responsible for meeting the
objectives of the Hazard Communication Standard in their specific
departments. One member feels that the more he knows about the requirements
of the standard (and I am the one who is supposed to to train him) the more
responsible he will be if an injury occurs and a student decides to pursue
litigation. So, he feels it may not be in his best interest to serve on
this committee or learn more about HazCom.
Any thoughts on how to motivate him in the right direction? Or, is he right?

I went round and round on this with someone the Chemistry Dept appointed to
our committee. There was an article in Chemical Health and Safety that
addressed this issue (for CHO's) as well (June/July, 1994).
The bottom line is that their liability is already established by being the
supervisor of a lab and joining the committee will not add to it, but
subtract from it by demonstrating "good faith" efforts to be informed.
Personal protection is provided by the institution's insurance coverage as
long as you don't do anything illegal. Obviously, nobody is protected from
that. It can be hard to convince someone who doesn't want to hear it that
that is a good deal.
The faculty member in question bailed from the committee and he was
replaced with someone more interested and better able to function,
providing the object lesson:
If they don't want to be there, then do you want them there?
Good luck

It's not an OSHA issue - OSHA only thinks in terms of "employer" and
"employee" and doesn't get involved in how the employer distributes
responsibility/liability to supervisors, committees, etc.
I'm in the Risk Management Dept here, which are the people who buy the
University's insurance. So they have the most practical knowledge of
liability issues. In response to the case I mentioned before, in addition
to a lot of others, they put together the policy I've attached below. This
is the long form of "the University will protect you if you're sued for
performing your duties".
The problem is that there are examples in environmental, occupational
health and regulatory fields of people being arrested and taken to jail
because of on the job activity considered criminal by the prosecutors.
These are extreme cases (either in the type of activity or the reaction by
the prosecutors), but are used as examples by lawyers to describe an
individual's legal risk in working in the health and safety field. That's
what gets people nervous.

I have addressed the liability concerns to our own faculty, after
having discussed the issue with the Assistant Att'y General; in short,
the answer is that the supervisor of a lab is responsible for the lab
and the degree of liability has nothing to do with being named CHO, or
as a member of a safety committee. Remember that Ignorance of the law
does not lessen a person's liability- therefore, it is better to be aware of
the regulations, and put in place policies & procedures to the best of your
abilities and resources, and cover yourself with a paper trail if the admin.
does not support specific items. A lab supervisor who does not have an MSDS
available for a student, or who KNOWINGLY puts a student in a dangerous
situation (working with a volatile toxic chemical but not providing a fume
hood) DOES increase their liability potential if the student gets hurt.
Think of it this way- if you claim that you didn't KNOW the speed limit, does
that lessen your liability if you crash into someone?

Our Anatomy labs use "Downey" fabric softener as a wetting agent on fixed

Your squirt bottle idea is safer than spraying.

The glove manufacturer's also have a great eal of information regarding
glove selection. I just picked up a software program from Best at the AIHCE
meeting in Atlanta last week. (Yes, Linda you can have a copy). They were
passing them out very freely. I have not looked for a website for Best or
any of the others.
Look also beyond the lab. Just finished a conversation with the director of
the automotive shop of the community college, his students really enjoy
using the latex gloves to help keep their hand clean. He had never heard of
latex allergies. Many art student use them also.

My personal experience. . . . . Previous to my current position, I'd
used only vinyl gloves, and when I arrived here, found the predominant
glove in use to be latex. I started having dry skin problems that I
attributed to the increase in hand washing that also came with the new
job. My hands became rashy, then weepy. Now I thought it must be the
soap, either in the lab or the ladies's room. I brought my own soap
from home and kept putting those latex gloves on to protect to weepy
rash !!!
I've had the same experience with nickel and earrings - a weepy rash on
my earlobes. I think "allergen" is sometimes looked over as one of the
lesser hazards of chemical handling, but for some it can be a potent
hazard. We had a student once ask us to call 911 if we saw her giving
herself an injection, because her doctor thought it might be a likely
occurrence for her to have an allergic reaction in the chemistry lab.

A cautionary note about RTECS data. It is comprehensive, gathering data
from all over, but may well include non-referred and otherwise less than
reliable data.
If this is critical, you may want to go to the original source--not always

I am interested in the recommendations that CHOs (or other lab safety

allowed to be stored in individual laboratories (teaching and
research). In particular, I would like to find out the maximum volume
of flammable liquid that is allowed to be stored outside of flammable
storage cabinets. I have read the NFPA 45 document several times but I
find their guidance some what hard to decipher and their recommended
maximum volumes seem high for individual laboratories. I would like to
hear what people think is really prudent (and feasible) with regards to
flammable liquid storage in individual labs.

I do not consider "recommended, prudent, and feasible" as interesting
as the "regulated" amount, which you never want to exceed. At my place
of employment, we are regulated by the UFC (Uniform Fire Code). If you
are under its jurisdiction also, send E-mail out on your campus asking
if anyone has a copy of volume 1. If no one there has one, you should
buy one. I can tell you how if you'd like. trobertson@csubak.edu

Although we discourage uncontained flammable liquids (FLs) in any volume (I
almost managed to write that without laughing), the max allowable FL volume
in labs is 10 gal. More than that requires at least one of the following:
1) reduction in inventory; 2) installation and use of an FL cabinet. Note
that the total allowable includes FL waste, a point commonly overlooked by
lab occupants.

Dear Colleagues--I generally second Jeff Rubin's recommendations: 10
gallons
flammable liquids (mixed classes, container types and sizes, per the
aveage lab)
maximum without a flammable storage cabinet; a maximum of 60 gallons
of
flammable liquids stored in flammable storage cabinets. We too
encourage
the use of flammable storage cabinets for <italic>all</italic>
flammable liquids. Preferably
properly maintained (keep the screen clean!!) vented cabinets with a
good
draw.
If more than 60 gallons of flammable liquids are in use in a lab room
this would constitute a "special use" area and would require special
fire protection
features, LEL monitors, intrinsically safe electrical equipment, etc.
This gets
really expensive really fast. The main type of research done in such a
room in
my experience is ether extractions conducted on a production basis,
such as
Mojonier (sp.?), or similar high volume work. These types of lab
facilities are
few and far between any more as everyone has gone to microscale and
intrumentation.

Subject: Re: flammable liquid storage requirements
In Ontario, Canada, we follow the Ontario Fire Code, Part IV. It
is quite stringent as regards labs:
5 liters of flammables outside an *approved* (UL) flammable
storage cabinet. Need not be in a safety can, but safety cans
are preferred. You may have in addition 5 liters of combustible
liquid (acetic acid, kerosine, etc). Most people don't use
combustibles so it isn't really an issue.
50 liters of flammables in the fire compartment (usually
individual labs, but some have been subdivided by drywall so be
careful how you determine the fire compartment). The 50 liters
must be in an approved cabinet or flammable storage fridge (not
50 liters in each!!). No 5 gallon shipping containers in labs
(no grounded dispensing system available).
5 liters of flammable liquids total in basements. Since we have
some basement labs, we declare NO ONE may have flammable liquids
since who would get the quota. This had resulted in several
labs being relocated upstairs (they get windows so no one is
complaining except those that pay the bill). Some labs still
require relocation. Some are able to limit their load of
flammables to 5 liters at a time (they may have an auxilliary
lab upstairs which contains most of the flammables) and they are
the only lab in the basement.
This is costing a lot of money for upgrading because several
storage vaults have been declared non-compliant because they
were in basements and people must control their inventory to
stay within lab limits. We often hear that it is cheaper to buy
in bulk and they want to store it in the lab. The city fire
department inspects these areas and can issue citations for non-
compliance. It is amazing what people from "outside" in
uniforms can accomplish when you as an insider get nowhere.

The National Toxicology Program (NTP) has established an email
listserver.
The purpose of this server is to be able to disseminate announcements
and
other information about the Program to a large number of people at one
time.
For example
The NTP's 8th Report on Carcinogens was made accessible on
the
website
(http://ehis.niehs.nih.gov) May 21, 1998.
The next update issue will give readers that have electronic mail
capabilities
the option of subscribing to this listserver and to not receive future
printed copies of these NTP Liaison Office updates since the same
information will be sent by the email listserver.
To SUBSCRIBE to the NTP Mailing List send mail to rowley@niehs.nih.gov
with the word "subscribe " as the body of the message.
To UNSUBSCRIBE, send mail to majordomo@list.niehs.nih.gov with the
command "unsubscribe ntpmail" as the body of the message.

Stephen,
Your idea about scanning your MSDS collection sounds like a very
retreivable form in which to keep your information. However, if you
plan to scan only the identifyer and ingredient information, this may
not make your MSDS collection OSHA compliant. The Hazard Communication
Standard requires accessibility to Hazard Information on your materials
in addition to what their names and ingredients are.
Good Luck

Subject: Help identify gas cylinder
Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
I have been trying to identify an unusual gas cylinder
that has no label. The only markings on the cylinder indicate
that it was produced by a company called N.P. Pratt out of
Atlanta. All efforts to contact the company have failed, and
I believe them to be out of bussiness. The Compressed Gas
Association has a FAX number to which questions can be submitted.
When I sent them my question, they refused to help citing the
fact that I am not a member of the CGA.
The cylinder is about 5 foot tall, and unusually slender
(about 6" in diameter). It initially contained 3600 lbs. of
pressure. The cylinder is maroon with one large black stripe
across the mid section. The valve stem is also unusual, and
resembles a 2" diameter pipe extending from the top of the cylinder.
A typical regulator will not fit on the valve stem.
Please let me know if you have any suggestions on how to
identify the contents of this gas cylinder. Thanks in advance.

The connection may give a clue as to the type of material. Flammable
gasses have left handed threads. Connections are CGA- for example,
hydrogen is a CGA 350, a .825" -14 LH ext.
I'd call a manufacturer, mabe Linde or Matheson. If you can get your
hands on a Matheson Gas Data Book, it might help.
Look at the connection very carefully- it may have the CGA number
stamped in. You should be able to determine by looking if the thread is
left or right handed.
If you send me that info, I'll go through my copy of the Matheson book
for you.

If you have the capability, your best bet for ID'ing the contents in the
cylinder are to identify the actual CGA valve. This will specifically ID
the gas, or narrow it to a hazard class. The easiest ways to do this are
(1) ask your gas distributor driver to look at the valve. These guys
frequently can ID it on sight; (2) try every regulator you can find, until
you get the correct one - you then have the CGA valve. Once you have the
CGA number, look in any gas catalog and match it to the gas.
DO NOT OPEN THE VALVE - you could be very surprised!
PS - I can do this, but as a formal consulting project.

We require that all students in "Gen Chem I" purchase WSWC by Genium.
We spend 3-4 days in class on this book/topic in concert with a series
of 8-9 pre-lab sessions (20-30 min) that focus on particular lab
hazards. Test questions follow. The kids like Hugh.

Hello,
Who has aquatic toxicity test results on Formalin 10%, 6.7%, or 3% ?
If the test results indicate an aquatic 96-hour LC50 < 500 mg/l, then the
formalin is considered toxic in California. The method of disposal is dependent
on this test.
Our laboratory prepares different solutions of buffered formalin. For example,
a 3% formalin with sodium borate is used to preserve samples.
Thank you, Jeff

I am not sure how your local regulations treat this situation, but in New
Zealand we treat all containers as full unless and until they are gas free.
So if you have 80 5-gallon (20 litre) cans, you need to store them as if you
had 1600 litres of fuel. In other words, not under your bed!!. The
principle behind this is that in the event of a fire, empty cans full of
vapour will take off in all sorts of random directions at high velocity,
whereas full containers have sufficient heat capacity inthe fuel to burn
down to the level of the fuel (if they are plastic) but not generally take
off. We have exactly your situation at our surf clubs where their
inflatable rescue boats are outboard-powered and the fuel bladders are
stored in fire-rated lockers with appropriate isolation to the clubhouse,
depending on the quantities involved.

Are you sure all you need to consider is the aquatic toxicity? Our
supplier labels a 37% solution, with methanol as a stabilizer, as
"highly toxic and and cancer suspect agent." There are special OSHA
regs for formaldehyde, maybe special haz waste regs also. Try also
http://chemfinder.camsoft.com, type in formalin, hit enter twice, and
you will get a list of links pertaining to formalin (formaldehyde
solutions).

Hi All,
Another good book is the Lab Safety Pocket Guide published by
Genium.
All of the boos that were mentioned are available from LSI.
And in most cases, the cost is below the publisher's list.

Jeff,
You should weigh the cost of the aquatic bioassay (96hr LC50) which is
in the $200 ballpark, against the cost of disposal of your material. If
you are generating more than about 1 gallon per month (another ballpark)
it may well be worth spending the money for the bioassay. If you are
making much less than 1 gallon per month, the cost of disposal as
hazardous waste is probably too small to justify the cost of the lab
test.
If you do send a sample for bioassay, send one that has EVERYTHING in it
that your normal used preservative has in it ( formalin, buffers, chunks
of tissue, whatever) and not just a 3% formalin sample. I also suggest
that if you generate a variety of concentrations of this stuff, send a
sample of the "worst case", or pour it all together (assuming you
already do that) and then take the sample. Check with the lab to see
what sample size they need and how to preserve it (usually just kept
cold.)
Good Luck.

Subject: anhydrous ether waste
Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
Recently, our hazardous waste team cleaned out an old stockroom of some 5
gal. cans of anhydrous ether. Before we moved them, we checked that they
were stabalized with BHT and in steel cans (which further stabalizes
against peroxide formation). The material was about ten years old but
unopened and still full. The storage area was a passively ventilated brick
out-building with a flat roof and was hot inside due to ambient
temperature. Because of the temperature and the size of the containers,
there was enough internal pressure that the containers would not sit flat
on their lower rims, but rocked slightly. We transported in our waste
vehicle which does not have air conditioning in the box, to our waste
facility where we left the material on the truck overnight to cool and
intended to offload in the morning when the temperature was down. The
material was consolidated into 55 gal. containers the next morning without
incident.
In your experience would you have done this task differently? How?
There are some follow-up questions that I would like to ask, but for now
I'd like to leave you with the open question.
Thanks for the help

Greetings Jeff,
When I worked at a marine science lab the ichthyologist converted their
museum collection from formalin to ethanol. We had drums and drums of
formalin waste. Although not covered by RCRA we did have our waste
hualers take the drums away for incineration. It was pretty
inexpensive.
I am not familiar with CA rules but I guarantee that no fish will live
in any of those solutions.
This probably doesn't help. Oh well, good luck.

Not only could you be surprised, you may become very dead. It isn't worth
messing around. Have it picked up by a company specializing in disposal of
unknown cylinders.

Subject: Re: Help identify gas cylinder
If you have the capability, your best bet for ID'ing the contents in the
cylinder are to identify the actual CGA valve. This will specifically ID
the gas, or narrow it to a hazard class. The easiest ways to do this are
(1) ask your gas distributor driver to look at the valve. These guys
frequently can ID it on sight; (2) try every regulator you can find, until
you get the correct one - you then have the CGA valve. Once you have the
CGA number, look in any gas catalog and match it to the gas.
DO NOT OPEN THE VALVE - you could be very surprised!
PS - I can do this, but as a formal consulting project.

Ron,
Let me answer your question with a question. Do you think you were
CORRECT in handling the ether in this way, or do you think you were
LUCKY in handling the ether this way? I don't know.
I can tell you I have seen 5+ year old ethyl ether in a metal can, maybe
opened, maybe not, with no detectable peroxide in it. This happened
about 5 weeks ago. I have also seen diethyl ether 24 months old, in a
metal can, never opened, with approximately 3 ppm peroxide in it. Both
were stabilized. You never know. The addition of stabilizer and the
use of metal cans will retard, not prevent, the formation of peroxides
in diethyl ether. There is also some data which suggests metal salt
contamination (rusty cans?)accelerates peroxide formation.
By the way, did you happen to test your ether for peroxides, just to
satisfy your curiosity? I'll bet your waste hauler would appreciate
the information.
I don't happen to know at what concentration of peroxide the ether
container will explode when it is moved. I have never seen numbers on
this, and I have so far resisted the temptation to determine it
empirically.
If you are interested I have a clipping of an incident at UC San
Francisco Medical Center several years ago where a medium size research
lab was damaged (4th story window blown out of the building, etc.) when
several bottles, including some old ethyl ether was MOVED about three
feet. I don't have the copy in front of me right now, but this is
fairly close. Let me know if you are interested in a FAX copy.
It is also quite possible that your local bomb disposal unit would have
been willing to run your ether as a very live exercise - maybe even for
free if they could coordinate the exercise with some other training
schedule they have. I have done something like this several times
with our Sheriff Department's Bomb Disposal Unit. They just love picric
acid. Maybe you would have been in the news, too. And since being in
the news is possible, you should mention all this to the Appropriate
Administrator before jumping in, if there is a next time. (I have
experience with this, too. The Coast Guard came - long story.)
Please be aware that 5 gallons of any flammable liquid will make a
Godawful big fire. Allowing the cans to cool overnight was smart.
Scheduling 6 a.m. to move the cans in the first place would have been
smart, also. Perhaps the Fire Department would have enjoyed standing
by for the event (another good reason to choose 5 or 6 a.m.) in case of
a leak or worse.
Did you bond and ground the containers when you poured the ether into
the larger drum?
This answer to your original question is getting to be as long as anyone
should be asked to endure, but it was an enticing question.
The short version might be something like," Any landing you walk away
from is a good one."
Next time (and always) ask yourself these questions:
What is the worst thing that can happen?
What should I do to prepare for this disaster?
What should I do when it happens?
How angry will the family be if Mom or Dad doesn't come home any more?
Very few absolutes exist. Protect your people.
Congratulations on your success.
Thanks.

Trust me when I say that I have no intention of opening the
cylinder to check the contents. Just trying to identify them
so that we can have the cylinder picked up. The cylinder appears
to have an initial date of 1920!!

If the cylinder is that old, it probably doesn't have DOT markings on it --
which means it can't be legally transported. You'll have to get a firm to
come in and sample it on site, and if still contains anything hazardous,
probably transfer it to an approved cylinder for transport/disposal.
We had to do this 2 weeks ago with a 1943 cylinder with unknown contents
and no label. By the way, the fittings weren't the standard type -- the
cylinder had straight threads and current standard fittings have tapered
threads. The work crew had to call all the local hardware and plumbing
stores searching for the right fittings before they could finish the job.
For what it's worth, we used ETSC Government Services. They have a main
office in Illinois, a branch in Olympia, WA, and a website at
http://www.etscgs.com
We've been pleased with their service.
