So, it either B or C. In the worst case, they recommend not more than 2 gallons of class one flammable liquids per 100 square feet. Therefor your max is about 10 gallons if thats a class one flammable liquid.

Please read her entire posting before replying because she clarifies what she is looking for in the second paragraph. Julie O'Brien EXPO The Children's Museum and Archimica (Florida) I am working on a project for the Atlanta Children's Museum and need some help. We are working on writing a children's book on safety for early learners (4-7 years). At first we were going to base it on the five most common accidents for children, but we have come up with a new approach that will teach more critical thinking skills applied to safety issues. We would like to design a safety approach to every situation that children common accidents for children, but we have come up with a new approach that will teach more critical thinking skills applied to safety issues. We would like to design a safety approach to every situation that children could use. Does anyone have any experience with this or any suggestions for research? We are interested in doing an overall approach to safety, instead of "Ten ways to prevent fire" or "what to do when a stranger approaches you" specifics. First we would like to have a general safety theory and then utilize that theory to show how it applies in situations where children already know the safety rules. We feel this would help develop critical thinking skills and allow them to see how new situations fit into their safety schema. For example, most children know that when riding a bike they need to wear a helmet, because that is something taught in bicycle safety. However, how many children see that riding a bike and riding a go cart or rollerblading have similar needs when it comes to safety and that the same rules should apply. With a general approach, the children will learn how to view the situation and see what safety needs are there and apply basic safety strategies. I hope that clears up some of the confusion about my earlier post. Any suggestions?

For those of you who have never attended the Laboratory Safety and Environmental Management Conference (LS&EM '99) I would like to extend this invitation to attend and participate in what has become the premier national conference on laboratory safety and environmental management issues. For those of you who may be fence-sitting because of the cost of the conference, LS&EM '99 and its associated trainings are inexpensive compared to comparable commercial offerings and will give you much more bang for the buck at the same time. In the session I am chairing on Wednesday, July 28, Gary DeWinkle of Pacific Northwest National Laboratory is presenting a paper on an integrated safety management system used in his Laboratory and John Schaefer of John Hopkins University is telling of an algorithm used to determine the need for monitoring for chemical exposure in the laboratory. Both are going to be dynamite presentations. I will once again be giving the popular training, "Challenges from the Field: Topical Issues for the CHO." In this training I develop strategies for those difficult issues faced by many of us in the CHO position. My friend and fellow trainer, Neal Langerman, will also be chairing a fascinating session. Ben Owens if the Univeristy of Nevada, Reno, will discuss "Risk Assessment for Laboratories" and Robert Hill of the CDC will present "Chemical Safety Levels as a Potential Rist Management Tool." They are both going to be excellent presentations. Neal will also be presenting his trainings on "Clean-up of Small Laboratory Spills" and "Emergency Response: Contaminated Employee." Neal recently conducted spill response training here at Cornell for our EH&S staff and I can personally testify that he is a dynamic and innovative trainer. The above is just a small sample of the quality of the presentations and training to be provided at LS&EM '99. For additional information contact Dawnn Johnson at PRIZIM Inc. at 301 840-5748 or by e-mail at djohnson@prizim-inc.com. The early registration deadline is July 15, so you still have time to get the advance registration rates for the LS&EM '99 and its associated training.

They would probably need to be performed outside with lots of safety precautions. 1. Lycopodium dust explosion-Available from magic supply shops (lots of regulations on transportation of the powder) 2. Piezo popper-One drop of ethanol ignited in a film canister using a gas grill starter switch to create a spark. Available from Educational Innovations. 3. Potassium permanganate + glycerin--Example of rapid reaction between a strong oxidizer and a fuel source 4. Vapors from dry ice used to put out a fire (from a candle or match). Example of one way fire extinguishers can be used to put out a fire. Most of these require extensive safety precautions. Showing the precautions that you must take can be used as a "teachable moment". They are very effective as educational tools when executed properly. No one should perform the demonstrations I've described without learning a lot more about how they have to be excuted to be safe!! I can provide more information if you are interested. Also, there are some good videos of demonstrations which can be used to show what can happen if you do not follow the instructions on a procedure.

It just says they have been trained on the provisions of the CHP. We consider it a little motivation to follow the CHP and, also, a little CYA for us in that it demonstrates that we did make an effort to train them. I know it does not protect you from a suit, but it can be used in your defense to show you did do the training. Maybe it will impress a jury. Hopefully, we'll never know. "Semper Adventurus!"

I am having a rather heated discussion with a few folks about the CHP and the CHO responsibilities for a large research complex. They are stating that each individual lab at the site (there are hundreds of them) needs to have it's own CHP and CHO to oversee it in the individual labs. Their reasoning is that the CHP needs to be lab or process specific. The CHO would have responsibility for this. My position is that there should be one CHP and one CHO for the site. The CHP would address the company's site safety plan and response with regards to the Lab Standard. To make the program lab specific, labs should use Hazard Assessments to identify hazards and then develop SOPs (using the hazard assessments) for the individual lab's hazardous chemical processes. These documents would be used to train staff in the hazards of the individual labs. The lead investigator or lab manager would have the responsibility of doing and maintaining the HAs and SOPs and providing lab specific training . I do not believe the Lab Standard intended to have a couple hundred similar CHP documents or CHOs at each facility. Any thoughts, comments or convincing arguments for either philosophy would be welcome. Thanks in advance. Mark Yanchisin Coordinator for Clinical and Lab Safety Programs University of Florida Env.

I might come down squarely in the middle. Have the first part of each segment site specific. Then add in lab specific items as needed. Just watch out that the first section does not include anything that a given lab should not be doing. Remember, if you write it, OSHA will hold you to it. I think a CHO per lab, or per chem subdivision, is a good idea. Hard to see how one CHO could effectively cover 100's of labs. Just my opinion.

So long as the CHP covers all of the labs and all of the labs follow the CHP, you are complying with the standard. There are some challenges in implementing this approach, however. Are the lines of authority sufficiently defined that the CHO can implement the plan effectively? Do any of the labs want to do things differently, and if so, can the plan account for this? Can the CHO practically maintain an oversight of chemical procurement and prior approval activites as defined in the plan? And of course if the other route is chosen, the practicality of managing a hundred different plans and training a hundred different officers while maintaining some semblance of consistency - if there are different plans and an employee may work in more than one lab, the employee must be trained in each lab-specific plan. This could be a documentation nightmare and you may find that tracking and accomplishing multiple training requirements may be more resource intensive than the chemistry you do. The CHP was not intended to be a barrier to work but to facilitate it. Just some thoughts.

Warning, a long answer follows, Hit Delete now if you are not terribly interested in this discussion. Great question you pose in regard to the Lab Standard. We do not have a hundred labs in one building here at UNE, but we do have many small research labs and larger teaching labs that cover everything from Intro. Chem to Gross Anatomy. Like wise, the needs in these labs are very diverse. We have a university wide plan currently with a CHO in the College of Arts and Sciences and one in the medical school. We have recently added a CHO for our Portland campus which is part of the undergraduate programs. All of us CHOs sit on the campus wide safety committee with other coworkers and student representatives. I have developed a specific CHP for the Gross Anatomy lab that falls under my group of labs. This lab has a very short list of hazardous chemicals but a more difficult psychological component to deal with. It became apparent that this lab has unique needs and concerns for training that could not be addressed in an overall CHP. It also became clear that none of the other lab areas had these needs. In the process of developing the plan, I set it up in sections that could stand independently in the overall document. This way I can take sections that apply to all labs, add sections for specific info such as chemicals and MSDSs, Sops and put it all in a 1/2" binder for the lab in question. I find it easier to maintain records by having specific plans, than by trying to cover everything a one large volume that no one would ready anyway. Many of our labs have the same CHP because they are teaching labs that all do the same set of experiments. We have several clinical type settings that have similar needs as well. I'm sure you can group some of 100 labs into similar categories that will help minimize the number of different plans you need. I find my faculty are much happier dealing with regs when the information I cover with them is relevant to their work. Likewise, they are more apt to come to me for assistance since I am only dealing with the needs of a medical school. I have more credibility with them than say a CHO that falls under the umbrella of undergraduate programs. So much of safety compliance is convincing people you are a credible source of information and that the regs are relevant to their work and therefore it is in their best interest to follow them. If you have folks willing and ready to serve as a CHO in specific lab areas I would take them up on it. The more buy in you have in the trenches the more powerful your safety program becomes. I would look at divisions and departments within your facility. Group labs by similar function or interest areas and then take a look at how many CHOs that would mean. In list the help of these folks in specializing and customizing the CHP for their lab areas. I think you will find that there are many parts of the CHP that will stay the same. That is what I have found. We have a university safety manual that covers lots of the general stuff. I pull relevant chapters and add them as appendices to the CHP for the lab. If you already have a document such as this, use it in this manner. Then when employees get reassigned or need to collaborate with a different group or division, they need only review the SOPs and new hazards in the new area. Their supervisor or the area's CHO can take of this training in a matter of minutes with the CHP near at hand. Its not really that different from an orientation you would give any new employee in your area. I bet I have given you way more information than you wanted. If you could not surmise from the reply above, I would favor the individual approach to CHPs and CHOs. Maybe not one for every lab but not one for all 100 either. I think the best solution lies somewhere in the middle as one of our colleagues as previously pointed out. Good luck with your endeavor. You will never convince everyone, but you can lessen their doubts and build a consensus. I find this very valuable in dealing in academia.

Here at UNE we follow the Bloodborne Pathogen Standard. We take a universal precaution point of view and treat all bodily fluids as potentially infectious substances. In general, we would have students work on their own urine. It is really no different that the safety precautions you would have in place for a microbiology course. There is the possibility of bacterium in the urine samples. Gloves(latex or nitrile), safety glasses with side shields and a lab coat are the minimum PPE we require. Good hygiene, ie. washing hands in lab after removing gloves, and cleaning lab benches with a disinfectant at the end of the period are very important. Equipment and specimens should be autoclave or red bagged for disposal. Like I said, follow same safety considerations you would in any microbiology lab.

Do you have any chemicals that could spontaneously polymerize? Moisture sensitive materials are a concern because, as the bottles warm up after being in air conditioned rooms, the humid air will condense on the outside of bottles and can seep into poorly sealed bottles.

The campus or site CHO is needed to assure consistency, resolve campus-wide issues, and keep up with current events. But each campus has its own culture so it may be prudent to designate deputies. It is also prudent to decide whether CHOs or deputies are or are not researchers. Local CHPs can become a nightmare, as mentioned by Ben Greene. Congress mandated paperwork minimization some years ago, but it seems there is a lot of pressure nowadays working in the other direction. A central CHP granting discretion under specified conditions to deputies might be helpful.

A blanket CHP for the institution, implementing the hygiene plan in a general way, and then individual labs would have lab-specific standard operating procedures or protocols as part of their lab safety plan. Chemical Hygiene Coordinators would implement and train to the lab-specific sop and the CHO would keep all those folks heading in the right direction, provide resources and general training, be a "critical friend" for audits, etc. This scheme has worked in other institutions with which I am familiar.

Many thanks for all the responses. I also found a great many CHPs on the WWW that call for a 6-inch setback.

Some chemicals simply degrade at elevated temps. Some solid organics sublime at the higher end of "room temp" and many of these are toxic/noxious/nasty/etc. Some become unstable. And if you have volatile or flammable liquids, well... Needless to say, these are going to be a problem. Also, are you still getting room changes of air or is the air in the room simply stagnating? And what is the status of the humidity level? I recently found out that our campus has been taking the AC in our building offline overnight and on weekends to make ice for the chillers. I will be starting a war with facilities over that. I am less than amused at being called in at midnight (an hour drive in from home!) only to find out that the alarm that was triggered was due to the AC being offline! When I entered the solid chemical storage room, the air was barely breathable and probably VERY unhealthy. The temps were above 90 and the humidity was off the scale.

Obviously when you cause 1st/2nd degree burns on the skin then the water is "too hot" and if you induce hypothermia the water is too cold. In the Midwest, we have a phrase for "tepid" means, but suffice it to say you want the temperature to be just like Little Bear's Porridge---"just right." (That is to say, just right for deluge showering, not the optimium gruel temperature, whatever that may be.) I've seen some thermocouple/bimetallic strip controlled mixing valves available on the market. I might recommend looking into them for new construction. I think LabSafety Supply might have them. If you want, I can research this a little further. As far as retrofitting my existing lab, we're not going to. Too many $$ and engineering time. I figure that we can give a quick deluge at the bone-chilling Lake Springfield water temperature and then move to a real shower in a matter of minutes for the rest of the recommended.

My understanding is that the testing pertains to the transport and charging of cylinders (check out DOT regs at 49CFR 173.34). Most of our cylinders are swapped out to our vendor at less than one-year or less intervals, but we have several that are infrequently used and are at least 20 years, though in fine condition as per visual inspections. Could the legal experts among us shed some light on the testing requirements? Are there any testing requirements for the storage and/or use (not transport or charging) of cylinders, other than prudent visual inspections for obvious damage and defects? OSHA's 29CFR 1910.101 simply requires the employer to determine that cylinders are in a safe condition to the extent that can be determined by visual inspection.

The cylinder looked fine by visual inspection. However, since we didn't need it, I had the vendor pick it up anyway. When they tilted it to roll it on its edge over the othe cylinder cart, the bottom fell out. Literally. The *entire* bottom dropped out of the cylinder. It seems that, amongst other things, the cleaning crew had been washing, stripping and waxing the floor around the cylinder, with it never being moved. At some point during all that the bottom was eaten through. Luckily, it apparentlly leaked out the hydrogen slowly and in non-explosive concentrations. I think in this case, the *prudent* thing would have been to ditch the cylinder a loooong time previously, even though it seemed to be in good condition. Sometimes the transportation costs and the costs of a new/full cylinder outweigh the possible problems, not to mention the cost of demurage!

We have a sales representative who seems quite knowledgeable about this type of thing. Other than that, I cannot vouch for the accuracy of the information. The typical high pressure gas cylinder must undergo a hydrostatic pressure test every 10 years. The test dates are stamped near the neck. A user might pay a monthly rental fee, or might lease a tank for 1 to 10 years, or might own the tank outright. If you rent or lease the tank, it is up to the vendor to make sure the tank is within the 10-year period. The cost of doing the test is figured into the rental/lease fee. If you own the tank, it is up to you to get it tested every ten years. The vendor is technically not allowed to refill a tank that is "out-of-date." The obvious question is whether the vendor will notice that your customer-owned cylinder is out of date or not. This is sort of like whether the bar tender notices a customer is underage or not. At one time bar tenders did not always check ID's. But as the penalty got worse the number of young people getting "carded" increased dramatically, and today it's pretty hard for a young person to get a drink without showing an ID. There are several vendors in our area. Some of have old crummy-looking tanks and I suspect they are not careful about inspections, etc. But the company we choose to do business with keeps their tanks clean and they tell me they always check the inspection date before refilling a tank. I have been told that the cost for a customer to get a single tank tested can be significantly more than the cost of a lease. Plus, you have the headache of arranging to get the tank tested. Your local vendor might help you arrange this, but maybe not. For these reasons we do not purchase our tanks... we let the vendor have the headache of keeping the tanks tested... and we choose a reputable vendor. We have found a 5-year lease most economical for us... but whether the 1, 2, 5, 10-year lease is better for you depends on your vendor. Our Buildings-and-Grounds people just pay monthly rental on the tanks they use. Our vendor is generous in the sense they charge us for the total number of "tanks leased" without necessarily mandating it be the same gas each month. For example, if we currently have six tanks of a specific size on lease, they might currently be 2 oxygen, 2 nitrogen, 2 hydrogen. But if I want to send back a hydrogen tank back and replace it with a carbon dioxide tank of same/similar size, I can do it without a new lease. So our current vendor specifies the number of leased cylinders by tank size. Some vendors lease by the specific gas and would not allow me to apply the lease to a hydrogen tank this month and a CO2 tank next month. In other words... shop around. My vendor has warned me that the regulations for acetylene cylinders are about to get significantly more stringent. Apparently the internal mineral has to be inspected for integrity to make sure it fills the whole space without cracks in itself or between the mineral and the wall. They expect 50% of cylinders to fail on a regular basis. This means the cost of using acetylene will probably be determined more by the cost of delivery and rental (including inspections and cylinder replacements) rather than the actual cost of the gas.

If the hood is not performing, work in the lab is not safe. The August issue of ENGINEERED SYSTEMS will focus on laboratory design and laboratory airflow control systems. The theme of the issue is laboratories and their proper performance. As Joanna Turpin, Contributing Editor writes in the article, "When it comes to making sure a fume hood system is safe, there are many factors that an engineer must take into consideration. However, the final goal is always containment - if the fumes aren't contained, the system isn't safe." Judging from the continued appearance of newspaper and trade journal articles, it is apparent that we have not solved all the problems associated with the laboratory workplace environment, even thought we have been working on it since the early laboratory of Thomas Edison some 100 years ago, If it is YOUR lab, in YOUR plant, with YOUR technicians, you want to know: o At what face velocity should a fume hood operate? o Does a uniform face velocity at 100 fpm equal good containment? o Should hoods be tested according to the tracer gas challenge method? o Is variable volume room and hood exhaust flow better than constant volume? o Is there anything in the laboratory that compromises the performance of the hood? o How do you select design engineers that know what factors contribute to hood containment? Check out the articles presented in the August issue of ENGINEERED SYSTEMS and judge for yourself. You probably want a system in your laboratory that is based on testing, research, and experience yielding consistently reproducible results. o Do you want to know who is currently doing testing and what the results are? o Do you want to know what the current "state of the art" is? o Can fume hoods can be built that can produce 100% containment? o Is there a possibility that your existing hoods and air systems can be modified -- in place -- to improve containment and is guaranteed to be cost effective? o How are the different elements in the air flow system designed and assembled to achieve the needed containment goals? If you do not subscribe to ENGINEERED SYSTEMS monthly magazine, borrow a copy from a friend or read the articles at www.esmagazine.com. YOUR technicians, in YOUR lab, in YOUR university or college are worth it. If you want to do your own preliminary safety containment survey, GOTO http://www.accuaire.com and use our "10 Point Laboratory Ventilation Checklist." If you recognize that some of the listed symptoms are in your lab, call us and allow us to do a "walk through" and share our findings and experience with you. Swiki Anderson, Ph.D., P.E.

With experience in both industrial and academic laboratories, Jim gives a "real world" approach to safety issues in the laboratory. His stories are both interesting and pertinent, and interactive demonstrations help you deal with everything from creative wiring in the lab to administrators without a vision of what it means to have a safe workplace. Highly entertaining, and an excellent forum to speak openly about safety problems in your workplace. SATURDAY, August 21, 1999 8:30 - 4:30 Westin Canal Place, Terrace $249 non-members / $199 DivCHAS members How to be a More Effective Chemical Hygiene Officer Dr. Jim Kaufman, Mr. Russell Phifer, Dr. George Wahl Take a close look at the Chemical Hygiene Officer position, and prepare at the same time for the CHP Certification exam to be held the next day. Kaufman, Phifer and Wahl give a different slant to safety issues in the laboratory, focusing on what you do and how you can do it better. The presenters bring a wide variety of experience to the table, but the real stars of the workshop are you - past attendees note the interactive approach focusing on their problems, from getting administrators involved in safety to dealing with regulatory concerns. The course covers all of the content areas of the certification exam (presented on Sunday, August 22 through the National Registry of Clinical Chemistry), including a sample test in the same format as the real one. Whether you are a new Chemical Hygiene Officer or an "old" one, you will find something to put to real use in this fast-paced presentation.

Due to an upcoming renovation, all of our chemistry/biochemistry labs will be relocating to other parts of the same building. Specifically what I'm looking for is a checklist that covers the proper transport of chemicals (i.e.-segregation of incompatibles, carts with secondary containment, rubber safety carriers for acids, ppe, etc.) as well as proper storage and disposal considerations. My intention is to distribute this checklist to all laboratory supervisors for them to complete prior to moving any chemicals. It is my hope that this will prevent me from having to personally meet with supervisors to discuss these issues. Any and all help will be greatly appreciated. Thanks in advance for your time.
