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.

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

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.

We use this data base too. I love it. It is very easy to work with and =
can be used on PC's as easily as Mac's. We have been using it for 5 years =
now.
For what its worth, Janeen.

I use a Macintosh and I use FileMakerPro Database to inventory my
chemicals. I use MacLabelPro and BarCodePro to bar code and label all
bottles. One nice feature of this extremely easy to use program is that I
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.
This allows easy alphabetical sorting.

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
your time and assistance.

Like Becky at USDA we too are remodelling/rebuilding our R&D lab. Our
architect mentioned VAV as in "Of course you will need a VAV system." But
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?
Please feel free to answer me directly,
TIA

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.
