I would like to clarify some points that were brought up during the discussion: 1. In the NFPA 704 Standard (the fire diamond) it does state in its scope that the rankings address health, fammability, instability, and related hazards that are presented by short-term, acute exposure to a material under conditions of FIRE, SPILL, OR SIMILAR EMERGANCIES. It also states in the applicability section that the standard is not intended to address occupational exposures. Regardless of what the standard does state regrading scope and applicability, almost all companies who sell hazard communication supplies sells the NFPA fire diamond as a means of complying with haz com. Many chemical manufactures use the NFPA label as part of their hazard warning system on their labels of hazardous matierls. Whether we like it or not, it is a fact that many businesses use this system as their hazard communication labeling system. I would like to point out its similarities and differences to the OSHA definitions. I want to provide employees with useful information and if they are going to use the NFPA label, I want to show them it limitations and usefulness. In terms of ACUTE toxicity and flammability, NFPA and OSHA use the same criteria (see defintions of toxic, highly toxic, combustable, and flammable in 29 CFR 1910.1200 and NFPA 704 Standard System for the Identification of the Hazards of Materials for Emergancy Response 1996 Edition). 2. It is true that HMIS was initially developed for the paint and coatings industry. However, the scope and applicability of the system has been expanded since the time of its orginal development to other hazardous chemicals in the workplace (laboratories included). LabelMaster now has marketing rights over the HMIS system and has put out a HMIS Implementation Manual to assist employers with labeling chemicals in the work place. In the implementation guide are the criteria that is used to classify the rankings of health, flammability, and reactivity. The health ranking criteria uses the OSHA definitions of Toxic and highly toxic. They also use skin and eye irriation data to rank the health hazard of a chemical. HMIS references that their flammability and reactivity ratings are the ratings used by NFPA. Therefore, in rating flammability, HMIS uses the criteria used in OSHA's Haz Com for combustable and flammable. 3. I disagree that the HEALTH concerns of someone planning an experiement in a lab is different than someone useing the same or similar chemical in a pilot plant. Toxicity is toxicity, flammability is flammability, regardless of the setting. ****** There is so much information that workers have to be trained on just within the scope of OSHA. I am trying to keep what they need to know to a simple level. They do not know what 0,1,2,3, or 4 means on NFPA and HMIS lables unless they have something of reference to compare them to. Thank you to everyone who has participated in this discussion. I hope we all got something good out of it. My appoligies to the list members who are sick of this subject (written with humor intensions).

Compare adding 1 ml of 6N HCl to a reaction, vs pouring 50 liters in a pilot plant, and in another direction, using 0.1 ml in a microscale lab. Only really a health concern in the pilot plant. In addition the mass/volume ratio changes as you scale up. One can imagine dozens of comparisons. Now the intrinsic properties of a substance which might affect health remain the same (i.e. pH, LD50), but the health concerns are very different. Today's shift to universal PPE, and read the MSDS before doing anything, have made many of us think that everything is scary under all conditions, partly because the MSDS was originally designed for 55 gal drums or tank cars full of the stuff spilling. Some things are bad even in small amounts, e.g. HF, Na, Hg (mainly because it escapes recapture if you spill it). Many more are not. Still wouldn't drink them.

You may want to review the Safety Article "Protecting Workers in Hot Environments". One of the essentials is to provide plenty of fluid for drinking --- For those who use commercial drinks, nothing beats Quickick.... I use it on my Boy Scout campouts - the boys love it - great for atheletic teams too. Click on our QUICKICK sponsor to see their great prices - it will beat whatever you are currently using. ***************************************************************** TOP SAFETY NEWS OF THE WEEK OSHA Agrees to Recognize Crane Operator Certification OSHA will officially recognize the national crane operator certification program of the National Commission for the Certification of Crane Operators (NCCCO) as meeting OSHA requirements for crane operator proficiency. EPA Head Says Republican Budget Proposal Will Wreck Environmental Efforts She stated "the Republican budget resolution could roll back the basic protections to public health and the environment that Americans want and deserve. These cuts, if enacted, could affect EPA's ability to set public health standards that protect our communities. They could severely limit the enforcement of national laws that ensure safer food and safe drinking water. These cuts could limit our special efforts aimed specifically at protecting the health of children and communities. They could mean that cleanups of toxic waste sites will be delayed in communities across the nation. And they could mean that states will lose millions in resources for providing their citizens with healthier air and cleaner water." This sounds like election year politics to us. Fed Highway Administration Required New Refelctive Truck Standards The FHWA has amended the Federal Motor Carrier Safety Regulations (FMCSRs) to require that motor carriers engaged in interstate commerce install retroreflective tape or reflex reflectors on the sides and rear of semitrailers. The locations at which the retroreflective tape or reflex reflectors must be applied to trailers during the phase-in period is specified. [See Safety Engineering Prices on Reflective Truck Tape] ****************************************************************** RESPIRATOR CHANGE OUT SCHEDULES The revised OSHA Respiratory Protection Standard requires employers to develop a filter change out schedule based on use and environment.... many have written in asking how to accomplish this.... our recommendation is to check with the manufacturer... all the major manufacturers have developed a baseline change out plan.... Safety Engineering & Supply has just posted over 50 new prices for respirators of all types and styles .... these are the best prices ever seen .... I highly recommend using them... I did when I worked as a Safety Manager for a Fortune 500 company... these folks know what they're doing! ********************************************************************* Have a good week.

Ideally, elimination of storing incompatible chemicals together is the ideal situation, which segregation by hazard may not accomplish. Storing chemicals by chemical family may solve this, but what about multi-family compounds? Where do you store 2-chloro-benzylamine; with the halogenated compounds or with the amines?

I saw once where it was referenced approvingly by L. Bretherick, dean of authoritative info. on reactive chemicals (which reacted when they shouldn't have). Did anyone there seriously consider alphabetical storage?? If so, shame on them. In addition take account of no aggressive acids or bases above eye level, no large bottles above waste level, or even knees, put little vials or small jars on deep trays for easier retrieval. Also deep trays for liquids is good for spill control. Fasten backs or tops of shelving to studs, joists or other substantial members. Any chance at all for quakes, put lips or other preventers on all shelf edges, and latches on cupboard doors.

Five were taken to Santa Clara Valley Medical Center and treated for minor cuts and chemical exposure. The sixth was treated outside the basement laboratory in Duncan Hall. San Jose Fire Department's hazardous materials team sealed off the room to prevent fumes from spreading to the rest of the building, school officials said. The explosion occurred about 11:10 a.m. when a student mixed nitric acid and ethanol in a one-gallon jar. Those standing close by were showered with flying glass and spattered with the mixture, fire Capt. Rob Piper said. Craig R.

One of the experiments uses 2,4-DNP (2,4-Dinitrophenylhydrazine) to distinguish aldehydes and ketones from alcohols by forming a yellow precipitate with an aldehyde or a ketone. However, when I prepare the reagent, the yellow precipitate appears. The recipe that I have: 3.0 g of 2,4-DNP, 15 ml. of Sulfuric Acid, 75 ml. of 95% EtOH and 10 ml. of water. I thought that my problem might be occuring from the 1% of ketone added to the EtOH as indicated on the Fisher label. So, I tried MeOH, but that did not seem to make a difference. Does anyone else perform this test in their lab? Does it work? Is there another possible solvent to use in the reagent? I would appreciate any help you can offer! Thank you. Amy R.

The informal consensus was, 24 is max, 20 better -- unless the teacher always has a well-trained lab asst. (Cannot find this in my quickly scanned notes, though). 30 is an accident waiting to happen for 1 teacher. In any case, insist on good sight lines throughout the lab -- that will add a bit to safety. And keep traffic lanes away from hood fronts--that traffic will foul up ventilation systems. Try it (walking past hood face) while someone is holding a smoke tube--you'll quickly see what I mean. Are the administrators chemists? I doubt it. Mary Ann At 09:13 AM 4/8/99 -0700, you wrote: >On Thu, 8 Apr 1999, lucy zotter wrote: >> I said that I did not think that this 24/1 ratio >> was safe.

We were able to get it to work with anhydrous ethanol. Methanol has different solublity properties and this may cause problems. Isopropanol may work. We now use the non-denatured ETOH since we obtained an alocohol user permit from the TABC, and it works fine.

"When she stood up to see what it was, a needle was found poking through the seat with an attached note saying, 'You have been infected with HIV.'" The memo goes on to say that "the Centers for Disease Control in Atlanta reports similar events have taken place in several other cities recently. All needles HAVE been positive for HIV. The CDC also reports that needles have been found in the coin return areas of pay phones and soda machines." Can anyone shed some light on this report?? Thanks in advance.

I called the CDC in Atlanta, HIV section and they say this is a hoax!!! There have been NO substantiated reports of any incidents like this. Whenever you get urban legends like this call the "source" and find out if it is true rather than perpetuating it. I also called the American Cancer Society who has a web page on the email chain letter. If you do call CDC as I did you will get a long groan about this story.

It sure has been a busy week here. We are in the midst of Bacteriology lab for the first year med students. How does 56:1 sound to you for a student:teacher ratio? It is absolutely insane! But that's what I'm dealing with right now. Prof. Ternai makes many good points in this recent e-mail posting and I especially love the 12 to 16 students per instructor. I have had the pleasure of working with small upper level undergraduate labs with only 10 to 15 students in them. We were able to do some really neat stuff and the students told me they learned more in lab about genetics than they did in the lecture portion of the course. Unfortunately, these decisions are not always made by educators who have actually taught students in the lab setting. They are more concerned with FTE's(money) than educational and safety considerations. I must say that this is an unfortunate trend and I for one would like to see some very stringent guidelines put in place for all educational settings in this regard. All administrators are not so graced with common sense as we would like to think. Well, I'll hop off the soap box now. Hope you all have a great weekend, Janeen. ***************** Janeen Lapierre, CHO College of Osteopathic Medicine University of New England 11 Hills Beach Road Biddeford, ME 04005 E-Mail: JLaPierre@MAILBOX.UNE.EDU Phone: (207) 283-0170 ext 2446 Opinions are mine and not those of UNE. >>> "Prof. B.

One aspect of being effective is being safe. In this regard we operate, and we have seen others operate, on the basis that a lab size can be as large as 24 students, but there must be two supervisors once the size is over 12. (I have seen others use 15 for this number.) One supervisor is a regular staff member (professor/teacher) and the other is a TA or student assistant. Although it is clear some people assume that the 24 limit suggested by ACS is with one supervisor, it is clear many schools use two supervisors for 24 students, perhaps partly for the reason described in the next paragraph. The second aspect of effective (and we feel this is just as important) is making sure the students have a good educational experience. Are they getting a good interaction with a competent lab professional to answer their questions and to have the lab techniques observed and critiqued. We think this requires a ratio of about 12:1. At Bluffton College, with no graduate program, we have zero TA's. We have also found it difficult to rely on undergraduate lab assistants because they rarely have time they can schedule to be present for a two or three hour lab (unless it's their own lab). Therefore we only use professors, and we follow a 12:1 rule. Occasionally the freshman chemistry instructor has used a junior/senior chemistry student to help even with a 12-student lab. He got worried about spending so much time with one or two students that he was not always observing what happened behind his back. So he wanted a good chemistry student present to watch over the whole group while he was spending time answering the questions of one or a few. That enabled him to be very effective in the second meaning of "effective" as described above. Finally, let me point out a very interesting point that ought to have some weight with administrators at least in colleges. Most colleges advertise their student faculty ratio, and brag if it is low. A quick survey of the top colleges in the "US News and World Report" rankings of college shows that the best ranked colleges have student/faculty ratios around 10:1, and they boldly advertise that. As you go down in the rankings, the ratio climbs: 12:1 15:1, 18:1, etc. But even at some large state-supported universities the ratio is advertised at less than 18:1. So here's the point... In a lab experience, when so much is at stake both safety-wise and educationally-wise, how can a school sanction a 24:1 (or worse) lab ratio when they brag about an overall faculty student ratio of 10 or 12 or 15 to one? The answer is that they can't. And the good schools don't. The good schools have a 12:1 or 15:1 ratio in lab just like the ratio for the college as a whole. It is true that student/faculty ratios in public schools is higher. I believe our state requires a class-size average of no more than 24:1... although this is an average. But how could you justify that the intense atmosphere of a lab could possibly be one of the classes that exceeds the average? Michael D.

With regard to using sulfur on a Hg spill, Prudent Practices says: "The common practice of using sulfur should be discontinued because the practice is ineffective and the resulting waste creates a disposal problem." (page 89) PP recommends using the spill kit, which allows for Hg reclamation. Dave -- David C.

In any case the vacuum he mentions is not regular or even HEPA--they would just disperse Hg vapor more effectively. The old aspirator bottle, (run by water power, with a trap) rubber hose and pipet tip will help. The glass can be picked up with two index cards, and don't forget leather gloves for the glass bit. "Flowers" of sulfur dusted in the area will help. Then wipe all surfaces, including vertical nearby, with a damp towel. Dispose of all in heavy plastic bag, seal and mark as Hg waste. Good idea to wear shoe covering--even a plastic bag--in the area. Shoes can spread Hg pretty fast. And ventilate as Boyter reminds us.

(page >89) Instead of sulfur, zinc shavings makes an effective "sweeping compound" for picking up surface contamination too small for the pipette/vacuum. It works best on fresh spills - it forms an amalgam with the mercury. It's often sold by the jar in the catalogs alongside the Hg spill kits, usually with a bit of citric acid mixed in. It's meant to be used dampened with water, and I've found it effective. Disposal is still a problem. We containerize it and send it off as mercury waste, one of our most expensive waste streams. Lastly, there is a product called "Merconvap", a liquid meant to be sprayed on surfaces after clean-up to reduce the volatility of any remaining mercury. It contains a glycol (not sure if it's ethylene or propylene) and a sulfur compound to form a non-volatile coating on microdroplets. Good for cracks between tiles, along baseboards etc. Not recommended for spraying larger floor areas - it's quite slippery. I realize these aren't items you'll likely have on the shelf, but something to consider in stocking your spill kit. Don ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
