DCHAS folks, I find John Nail's argument below sound and thoughtful. I, too, have been a chemistry professor (28 years) and volunteer firefighter (15 years) and feel qualified to comment upon the use of a fire extinguisher in a lab. The first rule is: save thyself, and those around you. Fight a (small) fire with an extinguisher only if you feel qualified to do so, putting neither yourself nor others at significant risk. Large, raging fires cannot be extinguished with an small extinguisher regardless of the skill and training of the user. Small fires can often be extinguished; it is situation-dependent. Hands-on training is best, for sure, but read the side of any extinguisher: PASS: PULL the pin, AIM the extinguisher, SQUEEZE the handle, and SWEEP across the base of the fire. If it were irresponsible to allow an untrained person to use a small extinguisher, the warnings against such action (which do NOT appear on the extinguisher) would be in very large print. Indeed, the simplicity of the four steps invites use by the untrained. An ABC extinguisher works amazingly well (and leaves a lovely mess of white powder which is easier to clean up than a fully-destroyed lab). Assuming that the report below is accurate, I agree with John: what is OSHA thinking to cite an institution for failure to train employees to use devices that are designed to be used by the untrained? Shame on the local FD for removing the extinguishers; rather, they should have worked with the institution on training, if that's what they wanted. Dave David C.

Indeed, in your case it is obvious that you are well-qualified to use fire extinguishers when there is a fire in the lab. But I must take issue with your conclusion which comes close to assuming that everyone else is as well qualified to use fire extinguishers as you are. In my rather extensive experience, most professors of science, even professors of chemistry, are simply not qualified to use a fire extinguisher. And in a fire if the fire extinguisher-user does not know how to use that tool, the he or she often in their use of that extinguisher will enhance, not reduce, the severity of the fire.
