Does your freezer vent the CO2 gas, or do you not worry about it because
it's an ultra-low?

Subject: Lab air exchanges and VAV
Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
Is anyone willing to share their policy on air changes/hour in research
(chem, bio, rad) laboratories?
As we move to VAV systems we are advocating 10 changes/hour when labs are
occupied and 6 when the space is unoccupied. For us occupied means
occupied, not just when hoods are being used. UBC and UMC have various
requirements for 6 changes at all times, but there is little code guidance
in this area.
I am interested in design policies at other institutions, what standards
you set, how they are justified and how they are enforced. Please respond
to me personally and I can forward a summary to the list if there is interest.

Hi Folks-
I need your help!
Can anyone provide/supply/assist with a list (partial or complete) of
chemicals of chemicals that should BE (or should NOT BE) in middle or high
school classrooms? The "NOTS" list could get huge, but remember that this
is not a research situation - the obvious "bad boys" are already excluded. A
separate list for either or one or both of the two student age groups would
helpful. This is an international query - all responses are welcome and
appreciated! (I have already "hit" JAK for this... and his list is pending.)
I have a cumulative 13-year running database of the chemicals that are/were
available from the major U.S. secondary school science supply vendors. I need
to "weed" this list down. Your help is needed. The resulting list will
eventually become the "approved-without-further-CURRENT-concerns-or-
discussion" list of chemicals that all schools may have/order in my local
public school system. (Yes, I realize this opens a huge "can of worms".)
I am hoping for responses from: CHP's, CIH's, CHO's, C-CHO's, NRCC-CHO's,
NACHO's, ASSE's (not a joke- I am a member), etc. (Gee- does this seem to be
part of the current "alphabet soup" confusion???) I need this help
"yesterday"... I found out today that I chair the committee next week!!!!!
Responses can be either to me, or to the list. If interest indicates, the
names of all eventually-approved chemicals on the adopted list will be made
available to you!
Thanks for you help.

I haven't seen too many digital calomel electrodes (that give the same
response as a real one) or dropping mercury electrodes for polarography
recently.
I don't believe the idea shoud be to eliminate mercury in the academic
(college-level) laboratory, but rather teach young chemists to handle all
chemicals safely.

I should recall, but recently there has been a book by Janet Baum, who is
an architect who has been awarded prizes for attention to H&S consideration
in new lab design. You might also try "Guideline for Laboratory Design" by
Louis DeBerardinis, Janet Baum, et al, Wiley-Interscience, 1993. There
they say (p101) that there are few regs which specific air changes/hr, but
that some consensus rec's might be adopted locally. From ASHRAE to Los
Alamos labs, the recommendations ranged from 6 to 12 AC/hr. Elsewhere they
have remarks about balancing VAV systems. Perhaps John Palmer on y;our
campus might have a copy of the book.

Jim and Colleagues--We here at Cornell have an internal "Design and
Construction
Standard for Laboratories" which specifically addresses air changes per
hour (acph).
We specify 8 to 10 acph in the occupied mode and 6 acph in the unoccupied mode.
We agree that "occupied" means whenever anyone is on the room for any purpose.
"Unoccupied" means when no one is in the room, useally a night setback based on
some form of occupancy detection. We also insit that a night setback be
able to be
overridden by the lab staff if they are conducting longterm, high hazard
reactions
in a fume hood or other device where there is the potential for the release of
hazardous materials if "something goes wrong" overnight. This is a difficult
pill for our energy managers to swallow, but this is the price you have to pay
to conduct safe science. Tom

We are now using the Enviro-Safe thermometers (with the green liquid) and
they are just not working well. The column separates very easily and some of
the liquid sticks to the sides of the column as if the column were dirty. I
know the directions state that they should be stored upright but our
students calibrate their thermometers in the beginning of the semester and
need to keep them in their locked lab drawer.
I curious to hear from others who use these thermometers.

I have to agree with Harry. It is certainly appropriate to replace
mercury containing devices with mercury-free devices where appropriate and
economically feasible but remember that we will never achieve a
"chemical-free"
world unless we live in a perfect vacuum. We can use a silver-silver chloride
reference electrode in place of a calomel (mercury-mercury(I) chloride)
electrode. Digital barometers are nearly as expensive as mercury ones if we
want the same accuracy. (Note that a good Hg barometer ($750) can be read to
about +/- 0.2 mmHg while the typical "home weather station" digital barometer
($150) can be read to only about +/- 3 mmHg. To get comparable precision and
accuracy in a digital barometer would cost around $500 which if I were
equipping a NEW lab is would certainly consider. The cost would however be
hard to justify if I were simply replacing a perfectly good Hg barometer.
I believe that we need to teach all our students to work safely with
chemicals (PPE, proper ventilation, proper waste disposal, etc.) while
reducing
their exposure to ones for which an appropriate substitute of lesser hazard is
available. "Appropriate substitute" is the key phrase here. If we can carry
out the same experiment or measurement with a less hazardous method, then we
certainly should try to do so but if for pedagogical reasons and experimental
reasons we need to use a more hazardous material or method, then we must teach
our students how to handle it.

We tried switching to the Enviro-Safe thermometers and had the same problem.
I have since purchased some Ever-Safe thermometers (blue liquid) and have
not had as many problems. However, we are only testing them right now. We
will probably switch over via attrition.
As far as the drawer storage goes, we have the same problem. Various
"fixes" have been suggested. One is to make up a "common" set of
thermometers and either number them or label them with the calibration
adjustment. Someone on either this list or the NAOSMM list was
investigating the possibility of getting a vendor (I think they were dealing
with VWR, but I'm not sure...) to make small thermometer racks which are
slanted and made to fit into drawers (similar to the large ones already
available) but which are only large enough to fit about five thermometers.
I haven't heard back from her (him?). I'll check my archives and try to
track that down.

We are using the red-alcohol thermometers at the gen chem level (-10 C to
110 C)
but have not found a suitable non-mercury replacement for the organic labs
which need the high range (-10 C to ~ 250 C) thermometers. Does anyone know
of an affordable, acurate substitute?

I agree with both Harry and Robert. Minimize hazardous chemicals in the
lab, but don't eliminate them entirely--many offer unique learning
opportunities.
The younger grades are an exception to the above. One sophmore, who was an
the juvenile equivalent of parole, liked my general science class, the only
one he didn't cut. He ran off one day with the Hg from a barometer demo.
Wasn't too long after that I left classroom teaching. This was some years
back.

a couple of comments at the end.
Teresa R. Robertson
CSUB CCHO
The following materials are listed in the Science Safety Handbook for
California Public Schools as extremely hazardous chemicals "whose
potential hazards outweigh any benefit they may provide to the
instructional program."
2-acetylaminofluorine
Acrylamide
4-aminodiphenyl
aniline
arsenic powder
arsenic trioxide
asbestos
benzene
benzidine
beryllium and beryllium compounds
cadmium powder and cadmium salts
carbon tetrachloride
chloroform
chromium (VI) oxide and all hexavalent chromium compounds
cobalt
cobalt II oxide
p-dichlorobenzene
3,3-dichlorobenzidine and its salts
4-dimethylaminoazobenzene
ethylene dichloride (1,2-dichloroethane)
formaldehyde
hydrazine (anhydrous)
hydrofluoric acid
lead acetate
lead arsenate
methylchloromethyl ether
4,4-methylene bis (2-chloroaniline)
methylene chloride (dichloromethane)
alpha naphthylamine
beta naphthylamine
nickel powder and nickel compounds
4-nitrobiphenyl
beta propiolactone
sodium arsenate
sodium arsenite
vinyl chloride
The Science Safety Handbook for California Public Schools recommends
that the following materials be removed from school laboratories.
antimony
arsenic compounds - all
benzidine salts
benzoyl peroxide
bromine
calcium carbide
carbon disulfide
dimethyl amine
ethidium bromide
ethylene oxide
ethyleneimine
hydrogen peroxide (35% or greater)
lead powder
lead carbonate
lead chloride
lead nitrate
lead oxide
lead peroxide (dioxide)
lead sulfate
lead sulfide
mercurous/mercuric nitrate
mercury metal and mercury compounds
nicotine
nitrogen triiodide
perchloric acid
phenol (carbolic acid)
phosphorus (red, yellow, white)
picric acid

The Science Safety Handbook for California Public Schools states that
diethyl ether should only be used when no alternative solvent is
available, and that no other types of ethers are to be used in schools.
The California Department of Health Services has recommended that lead
and lead compounds not be used in the high school laboratory unless in
compliance with the CAL/OSHA lead standard which requires air
monitoring.

Since I haven't seen mention of polymer-coated thermometers yet, I
will suggest that labs that must use mercury-containing thermometers
for performance sake may be able to substitute teflon polymer-coated
ones. They don't eliminate mercury, but almost guarantee no
inadvertent spillage or exposure with normal and reasonable handling.
The down-sides are higher cost, possibility of clouding of the
coating to prevent clear reading (though we haven't experienced that
in a couple of years of widespread use in our teaching labs), and an
upper temperature limit lest the coating melt (~200 C). Fisher, for
one, provides a limited selection of temp-ranges/precisions in these
coated thermometers.

I sent all of my 0-100 C., 0.01 precision thermometers to Brooklyn
Thermometer Co. and had them teflon coated. There is a slight amount of
temperature lag due to the coating but no more spills! Unfortunately, I
even moved on from these to using digital thermometers from Fisher.

We, too, have had problems with VAV systems. We are presently removing this
type of system in our chemistry building and returning to a CAV system. The
system never worked properly, but I'm not sure how long it would have
worked anyway. Many of the parts used were not designed to withstand the
corrosive nature of what goes up those stacks! Food for thought for those
looking at VAV systems.

We tried the non mercury thermometrs. and found the greatest error comes from
the inability of the liquid to transfer energy effieciently. On full
immersion, the were equally accurate with Hg thermometers. But when only the
bulb was immersed, there was about a 2 degree error in the 70 C range and 3
degree around 100C.. We've switched to electronic digital thermometers. It has
improved our students' awareness that temperature does not "leap" in 1 degree
increments and have excellent response. BUT is this a mercury free lab? The
batteries contain Hg. Why are we as chemists so interested in "eliminating"
the materials that are our subject of interest? Proper use of a resource is
the key to our education strategy
Final statement. They kidnapped my Hg barometer. Good riddance, the digital I
purchased to replace it is far more precise, versatile and safe

Dear Colleagues--We have also gone away from full VAV for new design.
The
3 facilities that were constructed with full VAV have been problem
childern
for years. Our Engineering Section's latest tactic is to use two
position VAV
with some type of setback (keyed to lights, motion detectors, etc.) for
energy
savings. The setback is 50% of a system designed to provide 80-100
lfpm
face velocity with a maximum variation of +/- 15 lfpm over the face.
This is
with the sash full open. EH&S has most often endorsed this system type
as
long as there is a manual override of the 50% setback when this may be
needed
as required by the use of the hood. CAV is used in some installations
but usually
only when energy conservation isn't an issue or there is some special
use of
a capture device, such as a gas cabinet. <bold>*</bold>The operating
budget of a technical
facility must have adequate funds to support extensive controller
maintenance
as may be required.<bold>*</bold> The new fangled computer buildings
are great when they
run well, but if they malfunction, they are the very worst! My $.02.

The Raving
A Tale of Laboratory Terror
Ethan Allan Poe
Once upon a Wednesday dreary, while I labored far from cheery,
Over many a serious process and repetitive chore -
While I labored, barely flowing, a silent hazard was a'growing,
Not that I was in the knowing, work that day was such a bore.
I paid so little notice as work had become so much a bore -
Only 2 long hours more.
Ah yes, as I ruminate, it was just before my grant's big due date;
The previous night I had worked too late and spilled something upon the
floor.
Eagerly I wished the weekend; to go fishing down at the creek bend
Was all from my thoughts I could depend - I wanted to be in the great
outdoor.
Frivolously filled with thoughts of fun, my mind was not down on the floor -
Need to work just 2 days more.
All the hidden, heinous, horrid hazards of the material stor'ed
In my la-bor-a-tory, that might fill you with terrors never felt before,
Were to me only a trifle, surely not a loaded rifle
That might change my life or send me to the doctor's door
Trivial materials that I handle everyday behind my laboratory door;
This it is and nothing more.
As if that were not sufficient, to make my day much more efficient,
And with my sick days so deficient, I brought my child to work once more.
She was too sick to go to daycare - there must be something in today's air -
So I brought her with her play chair and entered though my workplace door.
I brought her to the horrors of my workplace, just beyond the laboratory
door;
I should do this nevermore.
You see I work with human tissue and blood and fluids that might issue
>From persons such as me or you - safe, simple specimens and nothing more.
Certainly I've heard of Hepatitis, HIV even sinusitis;
An S.T.D. surely a blight is, but not within my lab door -
You'll not find such organisms here within my lab door.
Try a lab on a different floor.
Sometimes with needles I give injections and in my lab I eat confections -
But still that spill needs disinfection with bleach solution (10% or more).
Should there be some caution taken with my lettuce, tomato and bacon?
Should my hands be washed then shaken? Are those hazards here and more?
Could that blood harbor such a menace, could danger lurk within the gore?
Is that all within my lab door?
Ah distinctly I remember, from safety training last September,
Human blood is a member of the biohazard core.
Even saliva in procedures dental, should be handled extra gentle;
Treat all blood and body fluids as if they carry something more -
Universal Precautions is the term from OSHA lore.
But that class was such a bore.
Nineteen-ten ten-thirty's the citation in 29 Code of Federal Regulation,
Bloodborne Pathogen implementation applies to all of this and more.
OSHA's concern in the 1980's, were some viruses straight from Hades;
Two vile, vexing, vicious virii straight out from the Plutonian Shore!
These might be found in any human blood or fluids and are often unlooked for
-
All too often, unlooked for.
HIV is the virus that can lead to AIDS - so un-desirous,
It starts with symptoms various, that might not be diagnosed for sure,
It can progress to immune aberration which allows microbial invasion!
"These secondary contagions cause the death," doctors do concur.
No vaccine prevents this and no medicine provides a cure -
For AIDS right now there is no cure.
HBV effects the liver, first phase of infection might cause a shiver
>From fever plus jaundice, joint pain, fatigue, nausea and more!
One might not know that they carry this virus of which they should be wary;
If untreated cirrhosis, liver cancer and even death might be in store.
A vaccine can halt this hepatic horror from colonizing the body's core -
3 shots with a needle - hollow bore.
And with proper selection of equipment for personal protection,
Gloves, glasses, sharps containers, and biohazard signage on the door,
Splash gear when splash is a worry, a schedule that slows my hurry,
And clean up before spills turn furry, I know safe procedures we could
explore!
The grim, ungainly, ghastly task of Practicing Safe Science might not be a
chore;
I wish I realized this before.
"You may recall that I have mentioned, I dropped my sample - un-intentioned
I know it grows un-imagined, it grows and spreads over the tile floor!
All I can think of is the warning of blood and things there borne in;
I did not clean it in the morning and now it grows upon my floor!
I dropped the beaker from out my hand, and now that stuff grows on my
floor!"
I should have cleaned that up before!
"Be this now our sign of parting, nasty job!" I shrieked, upstarting -
"I will quit to run and hide by some safe ocean shore!
I'm afraid now that I've spoken of that beaker I have broken!"
With much haste and no slow-poke'n, I ran out of my lab door!
Grabbed coat, check and child and in panic scurried out of my lab door
To be seen there, Nevermore.
And that Hazard, never slowing, still is growing, still is growing
On the tiles of asbestos there upon my old lab floor;
And it is so mild seeming, that the next lab worker will not be dreaming,
Of the horrors that could be streaming from that spill upon the floor.
And it is that next lab worker that will find what is on the floor -
Or will it grow for Evermore?
Alcohol and calculus don't mix. Never drink and derive.

Hi Folks-
I need your help (again)! This is a sequel to last week's request for
chemical "hit-lists". My first query got several direct and list responses
for which I am very grateful!!!!!! Thank you. The committee meeting on the
CHP update and development of an acceptable chemical list for my local school
system as been moved to the end of next week. I desperately need additional
individual, state, and local school system input!
Can anyone provide/supply/assist with lists (partial or complete) of chemicals
of chemicals that have been judged: should BE (or should NOT BE) in their
state's or county's or town's middle or high school science classrooms? If a
rationale for the choices is available, this too would be tremendously
appreciated. This is an international query - all responses are welcome and
appreciated!
When the committee meets (and I may well be the chair of this "monster") I
need to have as many facts and choices as possible. Anything you can provide
will help me!
Thanks for your help.

Members
I have read with interest the dialogue on the use of Mercury, Carbon
Tetrachloride etc. over the last weeks.
I am of a venerable age and when I started in laboratory work in the
late 50s, Mercury was commonly used, spilt, and cleaned up when one had
time. Sometimes weeks later. Carbon Tetrachloride was the degreasing
solvent of choice and Benzene was in common use. Asbestos was the
insulation media for pyrolysis furnaces and was tossed on the floor when
repairs were required. I won't mention the time we worked with Beryllia
or that PCBs were the lubricants for ground glass joints and Mercury or
PCB was used for liquid seals around stirrers.
I am not defending this apparent casualness but it was the norm of the
time. I am aware that some of my colleagues of that era have passed on
a little early but then most of them were smokers too. I and many
others survived and continue to survive very well. To read the
correspondence one would think that exposure to the vapours from one
Mercury thermometer was going to do immediate irreparable damage and
cause almost instant death.
Please take care with chemicals and teach your students the value of
safe practices. I worked in a plant where the SO2 levels were
abominable but it taught me to hold my breath when the smell got too
strong. Something I still do automatically when I pass truck belching
smoke. Don't make them paranoid about every little spill or a few ppm
of solvent vapour. Teach them to always use fume hoods, mop up their
spills as soon as they occur with the spill kits which I'm sure you all
have and to always use their protective equipment.
Laboratories are to be enjoyed for the wonders that can be revealed not
places to be feared as dangerous.

<< To read the correspondence one would think that exposure

JAK: It was reported in Lancet, that a family of five in Germany
broke a single rectal thermometer in a childs bedroom.
Within three months, a 20 month old, a 33 month old, and a six
year old all had visible signs of mercury poisoning and mercury
blood levels four times allowed by German law.
The children needed to undergo chelation therapy to remove the
mercury. Withinn nine months there were no traces of mercury
left. It had evaporated.
I suppose the damage is not immediate and irreparable and surely
didn't cause almost instant death. It is, however, a whole lot more
serious than we thought in the past as we rolled it around in our hands
and changed pennies into dime.
Yes, the good old days were great. It's just that being poisoned by our
ignorance was not one of the best parts. One mercury thermometer can
cause a serious and significant problem. It is not a cause for hysteria
nor should it be treated with a casual indifference born out of habits and
attitudes breed in the past. ... jim

Hello, group!
I wonder if anyone could help me with a problem I am facing.
We will be undergoing a major remodeling soon in our science building.
Our administration/architect seems to feel that biology labs do not need
hoods. Hoods are very expensive, they say, in maintaining the internal
temperature of the building and why do we need one in every lab. I plan
to take MSDS of chemicals and a list of procedures needing hoods used in
the labs to the meeting we are having next week, but could anyone add

Greetings,
Most bio. labs use formaldehyde with a pel of 0.75 ppm.
Proper levels cannot be attained except with engineering controls.
Anyway if you need more ammo OSHA says you have to have one to keep
exposures below pel. Scripture and verse. 1910.1450.(C)(4)(b). Look
in Section C 1. Design (c)The laboratory should have laboratory hoods
and sinks.
If OSHA law won't convince them well.... good luck

Just because it is a biological lab does not mean they will not be using
dangerous or hazardous chemicals. Refer your Administration/Architect to
ANSI/AIHA Z9.5-1992, section 4.3, and Laboratory Ventilation, ASHRAE
Handbook on HVAC applications, chapters 13 and 14.
Good luck, it is sometimes difficult to let those who hold the purse
strings know that they can pay now and make the place safe or
pay latter when a law suit if filed.
Hope this helps,

Subject: Electric fishing
Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
Greetings Labsafety
Out of the lab and into the field, electric fishing is used by ecologists
for fish sampling in small rivers and lakes. The technique involves passing
a pulsed dc current through the water from a mains voltage generator or
battery powered pulser
Electric fishing in New Zealand is regulated by Ministry of Commerce under
the electricity act. Electric fishers must train, and there are
regulations that govern how many persons must be present, types of
equipment and so on.
Staff at National Institute for Water and Atmospheric Research (NIWA) are
debating the risks of electric fishing using mains voltage generators and
battery pack equipment, the risks of heart attack and whether or not
defibrillators would assist in case of accidents. There have been no
recent accidents involving electric fishing equipment and the risks appear
relatively low.... rather like an aircraft accident in that if anything
does go wrong it will be serious.
Do any LABsafety members:
(a) have reports on any electric fishing accidents in the US in the last
ten years
(b) information on subsequent accident investigation, age and condition of
victim, and the nature of harm etc
(c) any opinion on whether defibrillators would have materially affected
the outcome of any such accident.

Hi-
Welcome to the wonderful world of trying to make an architect understand how
labs need to work! We had a renovation of our science building about 3 years
ago and it was NOT FUN.
Yes, we do now have hoods in our biology labs. The environmental science
classes can now use their muffle furnaces in their own lab and hoods are
available for chromatography expts that use petroleum ether. We also have
one in the microbiology/genetics lab.
Hope this helps you - your idea about taking MSDS to the meeting is a good
one.

Faculty usually have influence on decisions like this. You may want to
bring up the following points to the faculty of the building:
*If the remodeling does not include hoods, what are they going to do when
they want to research that requires a hood as part of a funded grant?
*How are they going to adequately control substances such as known or
probable carcinogens?
*How are they going to control acutely toxic and mutagenic materials used
in DNA research?
*How are they going to ensure that students in laboratory classes are going
to be protected from hazardous chemicals in their experiments?
I think Michigan is under a state OSHA. Requirements of the laboratory
standard (1910.1450) would apply as well.
Good Luck

In the summer of 1997 we evaluated a half dozen MSDS management programs.
We settled on one called Scan Wizard. It is distributed by SafeTec Software
(formerly Eclipse Software) of Vancouver, Washington. Contact Gary Jackson
(360/573-2929. I recommend that you evaluate several programs to see which
one best meets your needs. Every company we dealt with was willing to send
us at least a demo version of their software.

Subject: Inventory, MSDS management programs
Greetings All,
I've been looking at a company that will link our inventory to
each and
every (25,000) chemicals we have here at Carnegie Mellon. It is
acessible via the web.
Has anyone had any experience with programs that link
inventories with
original MSDSs? Let me know.

Actually, after looking at numerous demos and trial version, the REAL
version prices, I decide to create my own. At theat time we had just
switched to an all MS Office office, which gave me access to MS Access and
Visual Basic. In three months I had a working chemical/equipment,
inventory control and purchasing/transaction database. I am gradually
implementing hazard/safety info. Within 3 months the whole thing will be
'web-enabled' to allow anyone on campus to see our inventory.
The database part is really not difficult, although it still lacks some of
the 'niceties' of the commercial versions. One thing I haven't figured out
is how to get chemical names sorted properly. But that is a small matter
compared to being able to search, sort and query our entire inventory for
some obscure item.
Good luck in your search.

Use the CAS number as the primary sorter. It is a unique identifier. Many
chemicals go by more than one name, loosley analagous to Charles, Charlie
and Chuck, and variations throwing in middle and last names.
I was trying to persuade a purchasing agent to change his "alphabetical"
listing of chemical materials to sorting by general category. In this
case, e.g., adhesives, gases, metals, solvents, paints, and misc.. If
something were misfiled it was easier to find. Before shipments of
isopropanol had been filed under 'i', propyl alcohol, rubbing alcohol etc.
If filed under solvent, all versions came together, or at least closer.
Hope this might give you some ideas. But for academia, the CAS# sh;ould be
it.

Read this again... Does anyone link their electronic inventory to an
electronic MSDS databasae so labs can look at each chemical and hit a
"button" and get the corresponding MSDS?
ImmageWave does do this thanks Ray.

Hi Folks,
We are considering purchasing the software program for
our chemcial inventory put out by ChemSW called "Chemical
Inventory System". We are also looking at the BarCode and Remote
Inventory BarCode Modules (Total cost around $1800). When I
called the company the technician also STRONGLY suggested I
purchase the Contract Support (a yearly renewable warranty
around ($600.00) We are a small community college chemistry
department with less than 1000 bottles of "stuff" and would be a
single user. My questions for this group:
Is anyone using this system? How is it working out?
Does anyone use a barcode system? Does it save time or reduce
the work?
Can anyone suggest a inventory system for a small chemistry
stockroom? Managing MSDSs is not a problem. We have a nice
filing system accessible and easily duplicated.
Thanks! I look forward to your responses

We're using it- have about 14,000 different containers, counting duplicates.
System works well- our only problem with it is it's not user-friendly enough
for non- computer literate folks. they end up not using it, so the
inventory is out of date.
Also, when I installed it, it was difficult to set it up the way we want it,
rather than what they think it should be. It is difficult to print out the
inventory for any given lab, to do a physiacl with.
I wish I had a better system. WE do NOT barcode.

Ditto what Mary Ann said about CAS #. And sometimes, if you search hard
enough, you can find specific CAS # that apply to specific forms of the
same molecule (i.e., for different waters of hydration, etc.).
I've used Access since it came out 5 or so years ago. Flexible, friendly

Oh Tammy, no. CAS numbers are not assigned in alphabetical order - totally
random assignment. There is a nmemonic to the numbering, to verify that
the number is valid. The public portion of the CAS website describes it.
Also, ChemFinder by CambridgeSoft (http://chemfinder.camsoft.com) has a
description.
In your database, you should build in the capability to search on all the
names of the chemical as well as the CAS # and the property (corrosive,
etc.) and where it's kept and who's got it and and and <grin>. But, and
this is the important part, all the various names of a chemical should be
tied or linked to the CAS # for the chemical. This is what's meant by the
"primary identifier" in the database. When you get to finding the
chemicals on the shelf, they should be arranged by compatibility group and
then alphabetically within the group.
Hope this helps. I _have_ to get the incident report done on the
rope/cow/thumb fiasco <g>.

I use a Macintosh and I use FileMakerPro Database to inventory my

created both a chemical name field and what I call a rear prefix chemical
name. This field would show 2,4-Dinitrobenzene as Dinitrobenzene-2,4.

I'm using this system currently. I bought it this summer. I am
barcoding, but did not purchase their barcode system. I simply purchased
what is called a "wedge barcode reader". It plugs in between the keyboard
and the computer and requires no additional software. I use the ChemSW
program to print the barcodes onto Avery labels purchased from an office
supply store.
I would recommend the support contract if you can afford it. I've run
into problems and had to call them several times. I don't know what
version you are looking at, but I got the CISPro because I thought it
would be more versatile over all. Initially, it had some bugs in it such
as not searching properly for the names and synonyms. I also had major
problems designing a report that I wanted and ended up purchasing the
query engine. Turns out, it had a bug, too. So, now they've sent me an
updated version of the CISPro software which also includes the query
engine. THe only bug I've found so far in that one is that clicking on
"exit" does nothing. I use the X in the upper right corner to exit the
program. I still couldn't figure out how to do the report I wanted, but
the tech support person helped me get it done.
Overall, I'm still of mixed feelings about the program. I love the way it
looks. I'm happy with the barcoding and the amount of information that
can be included for each chemical. I still need to get past the
frustration of getting what should have been a simple report written.

Here's some analytical methods questions dealing with air contaminant
sampling I know someone can handle.
1. Does the NIOSH measurement method for toluene, acetone, & cyclohexane
call for impingment (absorption) of these vapors in Carbon disulfide via a
sampling pump with GC/FID analysis to follow?
2. If so, is there something less hazardous than CS2 that is applicable?
3. Also, what is the most recognized method for arriving at TWA values for
these types of organic vapors?
Just doing a little research.

Here are the following methods used:
Acetone OSHA 69 Method Carbosieve S III
Toluene NIOSH 1500 Charcoal Tube (small)
Cyclohexane NIOSH 1500 Charcoal Tube (small)
Neither involve carbon disulfied in the sampling train. I got this
information from the Wisconsin State Lab. of Hygiene (U of Wisc). Call them
at 608-263-6550 (hope this is current).

According to the NIOSH Manual of Analytical Methods (NMAM), method 1500, air
samples are collected with a charcoal tube. The analyte is then desorbed
from the charcoal using carbon disulfide.

Greetings:
I'm afraid I came in on the end of the discussion re: VAV vs. CAV
systems for research facilities. I'm very interested in the subject,
especially since we're in the process of soliciting designs for a new
research facility (mostly biology, but some chemistry). If I understood
correctly, some of you have had problems with your VAV systems. I'd
be very interested in learning of first-hand experiences and the "pros &
cons" of each system. Since this subject has already been covered to
some extent on-line, please reply to me directly. Thanks in advance for

Like Becky at USDA we too are remodelling/rebuilding our R&D lab. Our

do we?
a) Obviously, from previous discussions, there is a lot of disatisfaction
with the systems out there - in fact does anyone have anything good to say?
b) One correspondant mentioned that the controls do not stand up to
corrosive conditions. We use a lot of SO3 and SO2, so corrosion concerns
obviously apply to us. Is there any way around this?
c) We are only a small facility and will require a maximum of (around)12
hoods. Since economics seems to be the main driving force behind VAV, is
this number of hoods sufficient to make VAV worth while even from this
standpoint?

We remodel a large number of labs here at Glaxo Wellcome and use VAV
primarily as an energy/installed systems saving measure. When you look
at straight economics, VAV appears very attractive - minimize the
outflow of air and you minimize the amount of energy and infrastructure
you need to support the laboratory(s).
On the negative side, the significant disadvantage that you need to
consider is the low transport velocity in the duct - this can result in
condensation or settling out of solids and corrosion or damage.
One should be very careful with diversity factors and placement of the
VAV boxes. A good point of reference is the Phoenix group - they are a
manufacturer of these items and their tech service people seem to be top
notch.
Good luck.

I don't know about OSHA (I'd think it'd fall under emergency procedures in
a CHP), but check out the Life Safety Code (NFPA 101), which covers
government buildings too. Chapters 10 and 11 cover new and existing
(respectively) educational occupancies; Chapter 5 , Section 5-10, covers
marking of means of egress.

Our undergraduate thermochemistry students do a "heat of vaporization"

acetone, isopropanol, and/or possibly other solvents to compare the
results. I'd like to substitute a safer solvent for the carbon
tetrachloride, but the instructor can't think of another solvent that will
meet her needs. She wants a non-polar solvent with a vapor pressure
similar to that of carbon tetrachloride (91 mm Hg), and a boiling point
below 100 degrees C. (CCl4 boils at 77 deg. C.).
I haven't been able to find a substitute yet. Someone told me the CRC

haven't found it yet.
Do any of you have any ideas?

You definitely should not be using carbon tet due to the health effects.
Try some of the new freon cleaning agents. The polarity might be
a problem.

I would stay away from the freons, that is if you can find them. Ozone
depletion is a hot topic. The closest substitute to carbon tet I know of that
is easily obtainable is trichloroethane. It's safer than carbon tet. It has a
level of risk but if done in a hood is safe enough and shouldn't get you in
trouble with the tree huggers. After all this is chemistry!

Two cents on trichloroethane (1,1,1 -trichloroethane, aka methyl
chloroform): I also like this solvent for its moderate (by comparison to
its peers) health risk and nonflammability, but it too is on the list of
ozone-depleting compounds, minus the notoriety of the freons. This has
lead to replacing it in some products with more toxic/hazardous substances.

This is true. When I first suggested a freon (I thought I said new freon),
I was refering to those that USEPA has given their blessing as nonozone

Subject: EPA Offers Assistance to Small Laboratories!
PRESS RELEASE:
EPA OFFERS ASSISTANCE TO SMALL LABORATORIES
EPA's Office of Small Business Ombudsman (OSBO) has published the long
awaited "Environmental Management Guide for Small Laboratories." With
over 30,000 laboratories nationwide, EPA believes this document will
meet a large unmet need to address unique environmental issues
associated with labs.
Small labs are found in academia, hospitals, water and waste water
treatment plants, and as testing, quality control, or research and
development functions in manufacturing and government organizations.
Given their wide scope, most communities have a surprising number of
labs. This is the first comprehensive EPA document addressing lab
operations.
Labs are unique because, unlike manufacturing operations, labs typically
handle a large variety of chemicals but in small quantities. Labs may
also handle radioactive or biologically active substances which raise
additional environmental concerns.
The Guide offers critical regulatory and technical information on key
environmental program improvement areas primarily related to chemical
handling. These key areas are management systems, air pollution, water
pollution, waste management, and pollution prevention. For each of
these key areas, the Guide includes a self-assessment checklist. The
Guide also provides an overview of relevant environmental management
areas, specific pollution prevention opportunities, and a long list of
relevant references for those who want more information.
At 54 pages, the Guide is designed to be a "must have" source of
information on environmental management at small labs. Many larger labs
will find it useful as well. To get a free copy, contact the OSBO
Hotline by calling 1-800-368-5888. Ask for the document by its title or
number (EPA 233-B-98-001).
For additional information contact Frank J. Priznar at (301) 840-9316.

Greetings,
In the past my concern about iodine has not been it's oral dose, it's
been it's inhaled dose. Iodine is a very good at sublimation. Put an
iodine bottle into another clear glass bottle and in a short time,
(weeks, months) you'll notice that the outside bottle turns brown.
If you drop a crystal on a white surface you'll quickly see
(minutes) how it moves. Pretty cool.
Iodine has an affinity to the thyroid so I always avoided any exposure.
In fact it was the only chemical I stored in the back of the hood.
Hope this helps.

Accordint to "Prudent Practices for Disposal of Chemicals from
Laboratories"
Nickel, palladium, platinum, and other metals or combinations that are
used as hydrogenation catalysts should never be allowed to dry in air
following a hydrogenation, for example on filter paper, because they are
prone to ignite. Filter cakes containg such catalysts should be promptly
moistened with water. Used nickel catalyst can be dissolved in
hydrochloric acid as described earlier in the same chapter to produce a
less reactive Nickel chloride which can be further precipitated as an
insoluble hydroxide and removed from solution to reduce volume and
disposal costs. I highly recommend you purchase the book. It is available
from Lab Safety Supply.

I find it hard to believe either number. 14g/kg seems way high, however,
14mg/kg would put iodine in the Universal Fire Code "highly toxic" category
(<50 mg/kg) requiring major limitations on its use. Note: industrial
organophosphate pesticides such as dicrotophos and dichlorvos have higher
oral LD50's than this!
More important than the oral dose is the inhalation dose, ACGIH recommends
0.1ppm as the ceiling.

Perhaps the original reference goes into more detail, but in California
the Department of Toxic Substances Control (DTSC) has something to say
about disposal of treatment residue "down the drain".
Concerning bench-top treatment, DTSC has approved only those methods
contained in Prudent Practices - approved as Treatment of a Hazardous
Waste Without a Permit. The treatment of Raney Nickel as approximately
described above is an approved treatment technique. This approval is
contingent upon a few circumstances:
++ The treatment must be performed by the person who generated the
waste, and the treatment must be done within 10 days after the end of
the procedure which generated the waste.
++ The treatment procedure should include confirming the pH of the
"aqueous" mentioned in the original post. Treatment of that liquid
(neutralization to pH less than 12.5 and greater than 2) is also
approved without permit.
I have seen a number of references ( books and MSDS information) that
describe disposal techniques that would be illegal in California if
performed as written. Please be aware that Hazardous Waste Regulators
in California ( and probably in other states) have a funny way of
deciding on their own what is acceptable despite what your best
reference has told you to do.

This is true about very nearly all waste disposal/treatment information I
have seen. Most of them at least have sense enough to mention that you
should check with your local and state regulatory agencies before following
their instructions. And they really do MEAN IT!!! Maryland does not have
the most strict rules out there, but I have seen some instructions given in
msds's, catalogs, etc that would definitely violate even ours!

Actually, fire blankets are about the worst thing you can buy. The old
fashioned idea of a "fire blanket" that you roll someone up in to put out
the fire has been the cause of many facial and respiratory burns. Wrapping
someone who has a fire on their person in a blanket creates a funnel effect,
forcing the fire up to the victim's head and face. Needless to say, this is
not a condition which one should want to create! The fire department's
"stop, drop and roll" is a better solution, even in a lab!
The better item to purchase in an Emergency Blanket. They are just as fire
retardant as the old fire blankets, however they do not come packaged on
rollers (as some of the old fire blankets did) and do not have the same
connotation as the old fire blankets. They are also useful for treating for
shock or hypothermia when necessary. They usually can be purchased in a
wall dispensing unit or a bag of some sort. I got mine from Lab Safety
Supply (800-356-0783). It comes folded in a soft green pouch that mounts on
the was and has a velco bottom closure, allowing you to pull the handle and
have the blanket drop into your hands. Very convenient. The nice thing
about the soft package is that you don't have to worry about students (or
faculty or staff) bumping into the corners and hurting themselves. I'm sure
there are other companies out there who sell equally good items.
My two cents.

Ditto on the danger associated with fire blankets, but there are a wide
variety of "emergency blankets" - some are flammable (not designed for
labs), smoe are impregnated with water-soluble gel (e.g., "Water-Jel")
which are designed to cool and cover burns. Problem is, even the
water-soluble gels can make initial treatment of 3rd-degree burns more
painful (due to residue removal) and interfere with grafting, althoug they
do put out fire well. Our EMS system evaluated their use and decided
against them; the Advanced Burn Life Support curriculum also recommends
against them.
For non-burning people, however, most emergency blankets are very nice.

Thanks to everyone who replied on this subject! I was asked to post any
good suggestions to the list, so here they are:
Re: Substitutes for CCl4 in "Heat of Vaporization" experiment:
1. Cyclohexane comes pretty close. BP 80.7 and vap press 100 mm at 25.5
oC. It is nonpolar and NOT toxic.
2. Try some of the new freon cleaning agents (those that USEPA has given
their blessing as nonozone depleters.) The polarity might be a problem.
3. I'm not an organic chemist, but when our latest organic chemist came on
board, he began to substitute dichloromethane as a solvent in place of
carbon tet.
4. The closest substitute to carbon tet I know of that is easily obtainable
is trichloroethane. It's safer than carbon tet. However, it too is on the
list of ozone-depleting compounds, minus the notoriety of the freons.
Re: Finding Polarities of Solvents:
5. I recommend you try Lange's Handbook for the polarities. They have a
table that has the dipole moments for a lot of chemicals.
6. Look in your CRC for a table of "Dielectric Constants of Organic
Materials ..." Organic liquids which have similar dielectric constants
will have similar polarities also.

Hi Tammy

For your purpose I would have thought a pure wool blanket would be =
ideal, but then, I come from a country with 3.5 million people and 50 =

This of course is used in conjunction with Stop, Drop and Roll. If the =

the rescuer rushing towards them. Wrap them, knock them over and roll.

Please save this message for future reference, especially if this is the
first time you subscribe to an electronic mailing list. If you ever need
to leave the list, you will find the necessary instructions below.
Perhaps more importantly, saving a copy of this message (and of all
future subscription notices from other mailing lists) in a special mail
folder will give you instant access to the list of mailing lists that you
are subscribed to. This may prove very useful the next time you go on
vacation and need to leave the lists temporarily so as not to fill up
your mailbox while you are away! You should also save the "welcome
messages" from the list owners that you will occasionally receive after
subscribing to a new list.
To send a message to all the people currently subscribed to the list,
just send mail to LABSAFETY-L@SIU.EDU. This is called "sending mail to
the list", because you send mail to a single address and LISTSERV
makes copies for all the people who have subscribed. This a=
ddress
(LABSAFETY-L@SIU.EDU) is also called the "list address". You must never
try to send any command to that address, as it would be distributed to=
all
the people who have subscribed. All commands must be sent to the
"LISTSERV address", LISTSERV@SIU.EDU. It is very important to understand
the difference between the two, but fortunately it is not complicated.
The LISTSERV address is like a FAX number that connects you to a machine,
whereas the list address is like a normal voice line connecting you to a
person. If you make a mistake and dial the FAX number when you wanted to
talk to someone on the phone, you will quickly realize that you used the
wrong number and call again. No harm will have been done. If on the other
hand you accidentally make your FAX call someone's voice line, the person
receiving the call will be inconvenienced, especially if your FAX then
re-dials every 5 minutes. The fact that most people will eventually
connect the FAX machine to the voice line to allow the FAX to go through
and make the calls stop does not mean that you should continue to send
FAXes to the voice number. People would just get mad at you. It works
pretty much the same way with mailing lists, with the difference that you
are calling hundreds or thousands of people at the same time, and
consequently you can expect a lot of people to get upset if you
consistently send commands to the list address.
You may leave the list at any time by sending a "SIGNOFF LABSAFETY-=
L"
command to LISTSERV@SIU.EDU. You can also tell LISTSERV how you
want it to confirm the receipt of messages you send to the list. If y=
ou do not
trust the system, send a "SET LABSAFETY-L REPRO" command and LISTSERV
will send you a copy of your own messages, so that you can see tha=
t the
message was distributed and did not get damaged on the way. After a while
you may find that this is getting annoying, especially if your mail
program does not tell you that the message is from you when it informs
you that new mail has arrived from LABSAFETY-L. If you send a "S=
ET
LABSAFETY-L ACK NOREPRO" command, LISTSERV will mail you a
short acknowledgement instead, which will look different in your m=
ailbox
directory. With most mail programs you will know immediately that this is
an acknowledgement you can read later. Finally, you can turn off
acknowledgements completely with "SET LABSAFETY-L NOACK NOREPRO".
Contributions sent to this list are automatically archived. You can get a
list of the available archive files by sending an "INDEX LABSAFETY-=
L"
command to LISTSERV@SIU.EDU. You can then order these files with a "GET
LABSAFETY-L LOGxxxx" command, or using LISTSERV's database
search facilities. Send an "INFO DATABASE" command for more information=
on the latter.
This list is available in digest form. If you wish to receive the
digested version of the postings, just issue a SET LABSAFETY-L DIGE=
ST
command.
If you are going on vacation or will be away for business and would like
to suspend email delivery, send a SET LABSAFETY-L NOMail command.
To restore service, send SET LABSAFETY-L Mail.
Please note that it is presently possible for other people to determine
that you are signed up to the list through the use of the "REVIEW"
command, which returns the e-mail address and name of all the
subscribers. If you do not want your name to be visible, just issue a
"SET LABSAFETY-L CONCEAL" command.
More information on LISTSERV commands can be found in the LISTSERV

Absent a mercury vac, one of the best ways to pick-up small droplets of
mercury is duct tape. Give it a try. As for overexposure, it is highly
unlikely that you will be overexposed from the small amount of Hg that will
leak out of a broken oral thermometer.

Someone recently pointed out an article in The Lancet, Dec. 22-29, 1990, p.
1578, which relates to household mercury exposure. Three children in a home
has chronic mercury intoxication. The source of mercury was a broken
thermometer in the children's room.

Concerning the Lancet article, a possibly critical factor in the incident,
mentioned in that article, was that the room had sub-floor radiant heat and
no ventilation per se.
For what it's worth, I recall a presentation at the AIHCE* of a study that
I believe was conducted by the Connecticut Dept. of Health roughly two
years ago that found no significant hazard in the breakage of single fever
thermometers in household settings.

I agree - in fact, the paper specifically mentions the room conditions
(small and unventilated) as being significant. The floor heating probably
helped accelerate the process (higher concentrations of Hg vapor over a
shorter time). Still, that's not much Hg. Any chance on finding that
AIHACE paper?

Here at CMU the folks in our Dept. of Health and Human Performance had a
small room where they stored their blood pressure
cuffs(Sphygmomamometers). This room had a carpeted floor.
On two occasions they had Mercury spills due to the apparatus being
knocked over. To remediate the situation I had to go in and physically
cut out large enough pieces of the carpeting that I could be assured that
I had removed all of the Mercury.Monitoring confirmed this. The pieces
were packed into open head drums for manifested proper waste disposal.
Ouch that cost a bundle.

Greetings Jim,
WOW! What a great idea ,duct tape. I hate picking up small mercury
spills. It can take hours chasing down the small droplets with a
hand-held Hg vac pump. As much as I hate duct tape simply because
people use it as a short-term fix and leave it as the long-term fix ,
this is a great idea. I have changed my mind about duct-tape. I will
try it the next time we have a small spill.
> Absent a mercury vac, one of the best ways to pick-up small droplets of

By the way the tape will need to be disposed of in a tight container,
say a zip lock bag, as Mercury debris. Pretty costly. Our vendor
charges $500 -$600 / 5 gal pail. So pick up the big droplets with the
vac but the small ones try the duct tape! The little mercury sponges
work well too but it takes time for them to react.

Another help in picking up mercury is to use tin foil. The tin and mercury
form a crumbly amalgam that is much easier to pick up and can even pull the
droplets out of some pretty small cracks. I don't know how much help it
would be on carpet,however. A plus is that the vapor pressure of the amalgam
is much lower than that of mercury.

Because we are all on the subject of Mercury spill clean up procedures I
thought everyone should be made aware of an excellent commercial product
I have used many times. It is called HgX Mercury Spill Control Powder
and it is available from Acton Associates, Inc.
100 Thompson St. Pittston, PA. 18640. I buy the 5 lb can for $30.00. As
everyone has alluded to when Mercury hits the floor it disperses into
tens of thousands of microscopic droplets that penetrate any crack,
between tiles, etc.and make 100% cleanup impossible. This product will
cover, amalgamate and greatly assist in containing and ultimately
removing all the Mercury.

Mime-Version: 1.0
Content-Type: text/plain
First of all, thanks to all who took the time to respond to my inquiry on the
subject. I appreciate the information. As is to be expected, there are
pros and cons to each system. I've been asked to share what I've
learned with the group, so here goes.
1. Base decisions on risks, use requirements, flexibility, future use of
space, etc., and not solely on dollars. (This may be hard to get the
engineers and fund-holders to swallow...you may need to spoon-feed
them on this one.)
2. Long-term cost factors need to be considered when looking at VAV
systems. These include the cost of long-term maintenance. Is there
qualified staff in-house to "babysit" the computer and electronics
systems? Is the vendor willing to train your staff, or will you need to
establish a "long-term business relationship ($$$)" with your vendor?
3. Some applications are evidently not appropriate for VAV systems.
Several people reported problems with sensors and controllers caused
by the caustic/corrosive nature of materials used in the hoods.
4. If pursing the VAV option, Phoenix controllers seem to be the only
way to go.
Again, my appreciation to all respondents. You've been more help than
you know!

Since we are discussing chemistry, let's keep kinetics v. thermodynamics
straight. Yes, mercury forms amalgams with a number of metals. It will
happen, if you wait long enough. However, the kinetics of the reactions are
very slow. In powder form, the reactions go faster, but even then they are
slow. Sulfur and other metals for a surface coating on mercury drops which
adhere by electrostatic forces. These are not amalgams. They do lower the
vapor pressure, until disturbed.
The only product I have found that works fast (20 minutes or so) is MERCON
from EPS Chemicals in BC. Check the archives for their address.
As to your carpet issue - cut it out and dispose of it as a hazardous waste.
In tight homes, the bed room ventilation is poor. It is not worth exposing
a rapidly growing nervous system, as in a child, to the mercury vapor. And,
yes, there are well documented reports of a single fever thermometer (1/2 g
of Hg) causing an over-exposure with symptoms.

Perhaps the theoretical reactions go slowly, but I have used tin foil for
years ever since stealing the idea from a Swiss grad student who said that's
the way they did it back home. I'm here to tell you that when a thin tin
foil comes into contact with liquid mercury it instantaneously becomes a
crumbly solid that is easily swept up with a brush.

Both are terms for air flow management in laboratories
VAV = Variable Air Volume
CAV = Constant Air Volume

Prudent Practices... says:
"Constant air volume (CAV) air supply systems...assumes
constant exhaust and supply air flow rates through the laboratory."
"Variable air volume (VAV)... systems are based on fume
hoods with face velocity controls. As the users operate the fume hoods, the
exhaust volume changes..."
Think SAFETY.

Subject: Ethidium bromide waste
MIME-version: 1.0
Content-type: text/plain; charset="us-ascii"
Hello group-
Two of our labs have been generating ethidium bromide waste in the form of
used stain and gels. I've seen a couple of protocols for dealing with
waste, but the chemicals used in these are fairly nasty too!
The method described by Bloom et al. (1996) adapted from Quillardet and
Hofnung (1988) uses KMnO4 (an explosive), HCl, and NaOH. After treatment
they recommend that you "discard the disabled solution down a sink drain.
Drain disabled gels, and discard them in the regular trash."
The new EPA guide for small laboratories mentions destroying ethidium
bromide w/ NaNO2 and hydrophosphorus acid, but there is no protocol, and no
indication of what to do with the waste.
Obviously I'd like to use a protocol that is safe and reliable. I
understand that the bleach method does NOT work. Any suggestions?
Many thanks,
Dorian

Good morning:
We've had two "bat encounters of the rabid kind" on campus recently. It's
the migration of the Mexican bat to its wintering grounds and so we're
pretty batty around here for a few weeks <har har>. Seems sort of
appropriate, right before Halloween.
Our campus vet has posted an excellent article up on our website and I
thought the group might be interested.

Greetings all,
I thought you might be interested in an article I caught while visiting
in Boston last weekend. This article appeared in MIT's "The Tech"
Dated Oct. 23, 1998 (hot off the press). I reserve comment until later.
LAB FIRE CAUSES LIMITED DAMAGE
A solvent fire in a chemistry lab in Building 6 Wednesday closed much
of main campus for several hours.
The fire began around 1:15 pm in Room 6-430 when a graduate student
dropped a bottle containing about a liter of hexane about 10
centimeters, according to W. Gerald Diaz, director of the safety office.
The laboratory is used by student of Professor of Chemistry Richard R.
Schrock. Two students were in the lab at the time; no one was hurt.
Hexane is a "standard, routine solvent" that is "similar to gasoline in
flammability," said Rick L. Danheiser, professor of chemistry and chair
of the department's safety committee. [insert photo of ladder truck
with firefighters.]
After dropping the container, the graduate student threw several spill
pillows on the liquid. Such pillows are designed to control substances
like hexane by absorbing them. Those pillows are required in all labs,
Dannheiser said.
However, four pillows were not enough to control the fumes, and the
fire started when they came into contact with an ignition source. "We
suspect is was a drying oven" which was located close to the spill,
Danheiser said.
Eyewitnesses said the fire gave off very thick, black smoke almost
immediately. Those near the fire could not fight it because of the
smoke, said Ann S. Jones G, who was standing in the hallway outside the
lab when the fire began.
No one was hurt by the fire, which was contained by several Cambridge
Fire pumper and ladder trucks: Most buildings reopened around 3 pm.
Test conducted in the lab after the fire showed that the residual level
of hexane was "well below dangerous levels," Diaz said.
EXTENT OF DAMAGE UNCERTAIN
Reports of the level of damage to the facilities have differed.
Initially, reports said the lab was a "total loss," according to Sarah
Wright of the News Office.
However, reports yesterday indicated that direct damage to the lab was
minimal, and that most damage was from smoke and water. "No valuable
equipment as affected," Danheiser said. In addition, no data was lost.
Damage was contained to the lab, which was scheduled to be renovated
soon.
Danheiser said that the researcher did nothing wrong, and that he
"would never criticize [him] for having a harmless accident." The fire
occurred "in spite of his best efforts" to control the spill.
One possible safety problem with the lab, however, is that a possible
ignition source was located close to stored flammable liquids, Diaz
said.

Some chemicals which have the potential to rapidly decompose with exposure
to air (like those listed in Prudent Practices) will have to be checked
frequently as a matter of safety.
As a matter of good laboratory practice however, most solid analytical
reagents, especially salts should be used or disposed within one to three
years after opening. It depends on "what school" you come from. To a
physical chemist, if it's still in the bottle, it must be ok. To an
analytical chemist, if it's not sealed with the lot analysis printed on the
label, it is not acceptable. Since I'm both (P-chem by academic training,
analytical chemist by job), I figure if it's been open long enough for a
group of lab techs to contaminate it beyond usefulness, then I need to
replace it. Experience has shown that to be about 12-18 months in my
current location. I try to order very small quantiites (10-100 g) of
chemicals which I know won't be completely used by the time they "go bad"
or are contaminated. That really cuts back on disposal costs as well.
For what it's worth....

We also have looked at purchasing "portable" eye wash devices for some

using the "eye wash in a bottle". Any help would be appreciated.

BIG NO on the squirt-bottles! They may be OK if someone is trying to get
an ordinary particle out of an eye, but are completely inadequate for
irrigation of chemical contamination. In addition, the water can
evaporate, start growing things, or precipitate them, depending on how well
the stations are tended. Eyewash stations that attach directly to faucets
will do if that's the only option, but they require a lot of action (for
someone with burning eyes) to operate. If you care to leave the water
trickling, so that someone need only pull the valve that redirects the
water, the running water can serve as an auditory guide, something pointed
out by one of our profs (but it does waste water). If the station requires
the user to hold onto something to keep water flowing, ditch it - it must
be a "hands-free" operation (in order to be able to hold the eyes open.
Another disadvantage of the faucet-mount is that it may require the user to
lean well over the sink, which could be difficult or even dangerous.
The best kind can be tied into sink plumbing (but not at the faucet), has a
slap or push plate that stays open, and delivers a generous flow.
Best of luck,
JNR

If I'm not mistaken you won't find any "specs" in the OSHA PPE standards,
1910.130 series. The actual eye and face protection specifications come
from the ANSI standards. For eye protection, that would be the Z87
standard. For Emergency Eye washes and Showers, I think it's ANSI 358, but
I may be off a few numbers on that one, since I don't have my copy of the
standards at home. However, the OSHA general industry regulations often
refer to ANSI standards, effectively elevating ANSI to regulatory status.
In a word, NEVER substitute the "eyewash in a bottle" for a regular
eyewash. First, ANSI doesn't allow for it. There are many requirements,
including "hands free operation," "15 minute continuous supply" as well as
pressure/flow rate requirements, and now, temperature requirements for
newly installed systems. You really have to get into the standard to pick
up all the requirements.
Good luck!

One of the OSHA references is 29 CFR 1910.151(c). It is vague and does
not specify minimum requirements.
"Where the eyes or body of any person may be exposed to
injurious corrosive materials, suitable facilities for quick drenching
or flushing of the eyes and body shall be provided within the work area
for immediate emergency use."
There are other specific OSHA regs. relating to eye washes for: open
surface tanks; storage & handling of anhydrous ammonia; powered
industrial trucks; hazardous materials, and a couple more.
I think most facilities use ANSI (American National Standard Institute)
specifications: ANSI Z358.1-1990 for installing eyewashes/safety
showers.
From a practical standpoint, I agree that bottles are not very useful,
but are good if they are the only resource you have. Employees/
students should be trained on the use of them.
Plumbed eyewashes are better, and stand alone are even nicer, because
you don't have to make your way to a sink which may have other chemicals
in the vicinity to add to the mess. ANSI requires the valves to be
stay-open, leaving the hands free; and plumbed units to be checked
weekly.
Another alternative is a drench hose, which will allow you to flush the
eyes or body; however, these do not have stay open valves.
A good resource for OSHA standard summaries is EZFacts, a fax-on-demand
system for some standards. (800) 393-2287. Just be aware that these
are summaries of the actual regulations.
Hope this is helpful-

Subject: eye wash stations/safety showers
We are going to install additional eye wash stations and safety
showers
in several teaching labs. We found some economically priced eye
wash
stations that fit onto an existing faucet. The manufacturer
claims this
device "meets OSHA specs". I would like to look at the actual
OSHA
regulation which describes the standards for eye wash stations.
Can
someone point me in the right direction?
We also have looked at purchasing "portable" eye wash devices
for some
of our maintenance people working in remote locations; these are
just
bottles filled with saline solution which can be carried onto
remote job
sites. I would like to know if anyone has had any experience
with
using the "eye wash in a bottle". Any help would be
appreciated.
Sincerely,
Karen A. Glover

that vanadium pentoxide dust is an irritant and there are serious problems
with chronic exposure. However, I haven't been able to find any

I would agree with Jeff on the BIG NO on the plastic bottles. We
have
disallowed these units and whenever we find one in place, instead of a
real eyewash, we attempt (usually successfully) to find funds to
replace
it with the real thing. There are industrial, portable eyewash
stations
that have a resevoir of several gallons of potable water but, as Jeff
pointed out, contamination can occur fairly easily in any portable
eyewash unless it is very well maintained. The larger portable units
are good for construction sites, but any workplace furnished with
running water should have plumbed in eyewashes of one type or
another.
>Eyewash stations that attach directly to faucets
>will do if that's the only option, but they require a lot of action
(for
>someone with burning eyes) to operate.
We have speced out faucet and sink-mounted units in some lab locations
where it would be very expensive to install a standard, free-standing
eyewash. The type mounted next to the sink which is automatically
activated when the eyewash head is swung out over the sink is the best
style as far as I have experience with sink mounted units. Re Jeff's
comment:
>The best kind can be tied into sink plumbing (but not at the faucet),
has a
>slap or push plate that stays open, and delivers a generous flow.
>Another disadvantage of the faucet-mount is that it may require the
user to
>lean well over the sink, which could be difficult or even dangerous.
This can be an important concern as many lab workers are too short to
adequately put their face in the eyewash streams given the height of
some
lab sink faucets. The benchtop, next-to-the-sink mounted units help
here, also.
Another significant concern, and one that is addressed by the tempered
water
qualifications of Z358.1-1998, is that a chemically blinded person may
reach a sink-mounted unit and accidentally turn on the <italic>hot
water</italic> in a
panic, <italic>not</italic> the cold water, and cause additional eye
damage from the
hot water itself as well as exagerate eye damage by creating an
exothermic
reaction, such as the mixing of H2SO4 with water in the eye.
(None of the above are very pleasant thoughts!!)

I don't want to dwell on this point, but I think it should be mentioned.
Regardless of the contaminant on the skin or the eye, Lots-o-Water is THE
immedate first aid treatment of choice at the lab. I think that any
secondary damage to the tissue caused by the exothermic reaction of an acid
or base will be insignificant compared to leaving the contaminant on the
tissue itself while we waste time wondering what is the treatment of
choice. A few drops of concentrated sulfuric acid just won't react
significantly with a gallon of water. Don't let a little knowledge of
"chemistry" interfere with "physiology" by overanalyzing this situation.
Secondary treatment given by EMS or other health care professionals can be
more specific to the contaminant.
Eileen Segal in the last issue of Chemical Health and Safety did a
wonderful job discussing first aid for HF dermal/ocular exposure. Though
the recommended treatment for HF is only 5 minutes of flushing while EMS is
on it's way, the important point for this discussion, I believe, is that
flushing is still the recommended immediate action.

Greetings,
I think I didn't explain myself vey well. I never ment that water
shouldn't be used when one had acid in one's eyes. I was just
comenting of the cold water vs hot water exothermic comment.
That's all.

Rules of thumb when I worked in a qa/qc, r & d lab and then in a contract
analysis lab. Good results depended on clean, reliable reagents. Liquids
and organic solvents I would keep for a year, if opened. The
peroxidizables or chemicals that are stabilized, like ether or thf, I used
the manufacturer's expiration date. For solids and non-hygroscopic salts,
I'd hang on to them forever <g>. But if there was no use for a year or
two, out they went. As far as I know, there really isn't a single
resource for expiration dates because there isn't concensus on when a given
chemical "goes bad."
For storage information, the uniform fire code and local building codes are
a good place to start. Contact the fire department - besides, they should
know what you're up to anyway. Someone else suggested Flinn - that's a
great resource.
Disposal information for hazardous materials will be in the regulations.
References like Prudent Practices are also a good resource.
Hope this helps.

Conserning faucet mounted eyewash-We bought two and my advice is -don't
Once mounted it became obvious that they looked efficient but could not be
used. Ours were designed to mount on what I call a goose neck faucet (not
flexible, just sort of straight up curving into straight down.
Too High and there was not enough room between the eye jets to the pipe to get
your forehead in. They would be great if your eyes were above your eyebrows or
if you got ink or dirt on your forehead and needed to wash it off. Probably
useful on Ash Wednesday but I can't think of any other time.
A bit of humor (but true) on a serious subject
By the way, we replaced them with a separately plumbed counter top mount.
