Jesus flipping Christ. I'm a chemist. I speak with authority: mercury is really not that toxic. Doctors used to prescribe it as a laxative. Granted, you don't want to be around if someone drops it on a stove, as inhaling the vapor can cause problems, but this school is completely buttfarking stupid. I could list a dozen things more toxic than mercury that are allowed in school.

Which isn't to say the assignment wasn't stupid. Literally "everything is from the periodic table."

Don' tell them there's mercury in all those 4ft. fluorescent lights hanging over their heads.

The stupid has infected this country. Time to start over.

The Irresponsible Captain: Wha? When did a mercury thermometer become hazardous? There must have been hundreds of those things around my school, especially, you know, for taking the temperature of things in Science class.


Cause people have a really crappy understanding of toxicology. Metallic mercury isn't particularly dangerous. People used to drink it back int he day when people were even more ignorant than they are now. Doesn't kill you because the bio-availability is very low. Neon shop workers are exposed to small amounts of mercury, since neon contains mercury, the few industrial studies show nothing.

Problems are organic mercury compounds in fish and mercury vapor. It's compounded because mercury is an insidious poison, and is neuro-toxic. Insidious because it's excreted very slowly so it's easy for continuous love level exposure to poison people.

Not this shiat again...

Elemental mercury is NOT dangerous unless you go out of your way to make it so! You can farking drink it with little effect, hell, you can INJECT it and have only relatively minor problems. Breathing the vapors, on the other hand, can be a big problem, as can organic mercury compounds.

Mercury

Pay special attention to the section "Mercury as a Poison".

Take away science and all you get is... Floridians.

If the thermometer breaks, the mercury cleanup is a pain in the ass. Given the potential to damage particularly if theres aluminum the mercury can get to, calling professionals saved money if anything went wrong. Usually, it's a money loser, but if it's done every single time Hg might be spilled, that overreaction probably saves money.


Plus, HAZMAT Team must make sure budget cuts never effect them.

As long as the themometer is not broken it is still safe enough to put up your bum.

It's stupid, yes. But I fail to see why the "government" part was necessary or relevant. Public schools are hardly the only places with dopey, zero-tolerance policies and disproportionate, hysterical behavior.

Magorn: Skirl Hutsenreiter: This is hilarious.

In my day, we did experiments with mercury-filled manometers in chemistry class. For obvious reasons, they weren't completely sealed like thermometers. You just rely on the fact that a protective oxidized layer forms on undisturbed mercury.

Coolest application: super cheap observatory lenses created by taking a bowl of mercury and spinning it up to a constant speed. It forms a parabolic mirror surface, and once the surface is stable, it's safe. You just have to pump out the hazardous vapors that were created while it was being spun up.

If that works why haven't we lauched about 55 gals of the stuff into space and made a truly huge space telescope?


You have to have gravity for it to work.

Unobtanium: Did anybody bring a smoke detector? I found out well after the fact that my school system at one time had a seed irradiator. Don't know if it was cobalt or cesium.


Americium is the most common element.

Well, any area of any size has to have one, just in case. So there are a lot of sunk costs. The real cost of the incident are tax-free gas that might not otherwise have been used, and what? I think it's a big deal over nothing like anyone else, I just don't see the authorities' response as particularly irrational. It's Florida and no one ended up shot, doesn't that have to be marked in the "Win" column?

In order to have nonsensical bureaucratic activity, it usually requires a government to be involved.
It just doesn't replicate much in a small school environment. Not that it could not happen. If a teacher or administrator happened to also be an HOA board member, you might see some of the same fine qualities that produce OC rules.

While we were taking a very tough Biology exam, our teacher dropped a chunk of sodium in a beaker of water. (Just for the lulz.) Did a hell of a lot more damage than a damned thermometer.
