Students, the Other Unprotected Lab Animals

theodp writes "Slate reports on the horrible — and preventable — death of a young UCLA biochemist in a t-butyl lithium incident, which led a Chemical Health and Safety columnist to the disheartening conclusion that most academic laboratories are unsafe venues for work or study. It's estimated that accidents and injuries occur hundreds of times more frequently in academic labs than in industrial ones. Why? For one thing, Slate says, occupational safety and health laws that protect workers in hazardous jobs apply only to employees, not to undergrads, grad students, or research fellows who receive stipends from outside funders."

Because you don't work with Milling Machines in CS or Oxy-Acetylene/Arc Welders while machining and assembling a CAR versus writing test cases in software. The fact this University doesn't have strict standards falls square on the shoulders of their full time professional staff who manage the labs and should be drilling into these kids Factors of Safety. If we ever mishandled metal lathes we got our asses chewed by the machinists.

      You'll never get the conservatives to reform the welfare system, because they don't want it to exist. Unfortunately, however, they also don't have the power to abolish it. In the end, you end up with a lot of petty arguments and underhanded political tactics, and the problem grows larger and larger.

      These sort of polarizing arguments occur quite frequently in university politics, and can result in safety standards not being properly implemented. Tenured professors can be very hot-headed.

  2. Mid-range time in the lab by Martin+Blank · · Score: 5, Interesting

    I wonder if some of the lab students fall into the trap of thinking that they knew enough, and not realizing that their earlier practices were put in place not to protect them as novices, but to protect them at all times.

    It seems similar to something that I've read happens to some pilots. In those cases, a pilot with, say, 200 hours still considers himself a novice, and will carefully follow the checklist and be extremely careful to not get overwhelmed. That pilot may reach 800 hours, and think that he's got it down. This is, according to one investigator (Australian, I think) the most dangerous time to be a pilot. Once this stage is passed, usually around 1500 hours, the pilot has had enough close calls to realize that what they learned early on should be applied all throughout their career.

    IIRC, this was the conclusion of an inquiry into a crash of an Australian military helicopter that killed most or all aboard when it came down too hard and too fast to the back of a ship, bounced off, and landed in the ocean. The base reason was "pilot error," but there was much more to the psychology of the situation.

      I don't know if it's overconfidence so much as getting lazy. I worked in a lab that was classified biohazard level 2 (I think) when I was a lab noob. Always wore gloves for one thing. I'm somewhat less of a noob now in a different lab. When I first started in my current lab, I would wear gloves for everything, even, say, when cutting chicken embryos out of their eggs. Clearly nothing in that which is going to hurt me.

      Now I've probably swung too far the other direction. I've caught myself doing stupid things like not putting gloves on when carrying a test tube full of toxins because I would have had to walk 10 feet to the gloves and was in a hurry. I guess there was a little "I probably didn't get any outside the test tube" but it was mostly just laziness and bad habits. And I think that's probably where most of the dangers in academic labs come from.

      Experienced researchers are often just as cavalier about dangers as anyone else in my experience, I think because a close call with lab safety, in some labs anyway, is much less dramatic than with a pilot. If you almost spill something bad on yourself, you might know it's something you want to avoid, but that's kind of academic. "Oh, a carcinogen almost landed on me, that would have been bad." You might laugh about it with your labmates next week, hopefully tell yourself you won't do that particular mistake again.

      If you almost crash a helicopter on the other hand, you probably nearly wet your pants, and the reaction isn't "Oh, that would have been bad," it's more "OHMIGOD I CAN'T BELIEVE I'M STILL ALIVE!" A much more viceral experience that probably causes you to be more careful with -everything- rather than just that one mistake. At least, I would guess that's the case.

Factories all keep track of the number of days since a reportable accident, and this number is rarely more than a couple of months. We get training each and every year on safety. We get monthly email bulletins of near misses and what we can learn. There are walk around audits of the lab areas.

      Example: recently the factory started requiring a splash shield over the standard wrap around safety glasses. Why? Someone splashed a small amount of isopropyl alcohol in their eye even though they had the wrap around safety glasses. Do you wear both a splash shield and safety glasses when you dispense IPA from a squeeze bottle?

      In grad school a woman was severely burned refluxing THF (flammable solvent) with metallic sodium (pyrophoric as in this article) in a glass round bottom flask in a hood (using an electric heating mantle). By accident the round bottom was not vented to atmospheric pressure (the stop cock was still in the neck). The THF was refluxing under pressure and this woman noticed and removed the stopper. The THF immediately turned into a gas, filled the hood, caught fire and exploded. Blew out the windows from the building.

      No industrial lab would allow a flammable solvent near an electrically charged heating mantle. This would have to be done in a Class 1 Group D flammable safety room (intrinsically safe electricity wiring and blow out walls (no windows), you have to wear ESD shoes to prevent sparking) in a sealed container.

      I work in an academic lab. We have potential biological, radioactive, chemical, cryo, electrical and magnetic field hazards. Without a serious safety regime it could be a dangerous place. Like most university labs we have very few undergrad students, who are continuously supervised while they are with us for short projects. Everybody has to take regular safety courses. We also have to report safety incidents. We have regular safety audits. This is normal for a university. That you rarely reach more than a couple of months between reportable incidents speaks as much for your own record as for the quality of the system, we typically go for much longer without incident.

      I think part of the problem here is that most university grads have not been grad students. As an undergrad you are well protected (mainly from yourself). The experiments you undertake have been pre-designed to allow for your limited experience. But it's cool to talk about how dangerous your lab work is. If you start working as a grad student, the safety training really starts. It's not about going on courses where you learn about what to do in a fire (we have to do those to), it's about learning to always look for safety risks in what you do. As a scientist, you are best qualified to recognise risks in your own experiment. A good scientist quickly forms the habit of always checking.

      In my experience, safety for our industrial partners means someone in their safety office has signed off on an experiment. For me, it means I sit down with a colleague or two and work out if we need anything above the normal safety procedure. Different approaches for different environments. Both can work, if done properly.

    And that's just one of countless examples I've seen. Undergrads, and even many grad students, don't really know what they're doing half the time.
