since this is the deadly poison thread https://www.theguardian.com/world/2016/aug/05/last-supper-japan-killer-puffer-fish-fugu quote:With help from a local fisheries firm and university researchers, the officials claim they have perfected a method of farming the fish that ensures the liver contains not a single trace of tetrodotoxin. If digested, the neurotoxin causes numbness around the mouth, followed by paralysis and death by asphyxiation. There is no known antidote.

Farmed fugu won’t sell. The poison is the whole point. A good chef gives you just enough to remind you of your mortality. It’s not like people are eating it for the taste.

My Lovely Horse posted:My chemist buddy told me about the time there was a small mercury spill on a wood floor some place. They pulled up a board, took a look, put the board back and called hazmat. It had not been the first spill by a long shot and there was a veritable lake of mercury under the boards that had accumulated over god knows how many years. Talk about floating floors. Yeah a prof at my mum's college in cambridge lived in a former lab and when he died they found the place was the same. In FOOF stories my mum almost killed my dad before they married with an experiment that went wrong and released cyanide gas. Luckily he's one of those who can smell it! She also blew her prof's eyebrows off when he opened a box with an experiment that she had labelled 'DO NOT OPEN, POTENTIALLY EXPLOSIVE' and he apparently thought he knew better than her.

"hey can you see how much peroxides in this sample" Sure thing pal! *Sets up for peroxide titration and squirts sample into glass flask just as the phone rings* "Uhhh I think I gave you a bottle of concentrated HF..." Yeah uhh you sure did since my flask looks a little sad.

So I work in a synthetic organic chemistry lab. A new guy that works next to me just made 4 grams of this: 6 Nitrogens : 4 Carbons is not a good ratio. Our safety officer has shut down the hood. I'm assuming there will be some kind of bomb squad in tomorrow morning. Here's a reference to the material: http://actachemscand.dk/pdf/acta_vol_38b_p0623-0626.pdf Of note (the compound in question is compound 4):

Wasabi the J posted:I'm only going off of what "Things I Won't Work With" and this thread's knowledge. 4g? Not safe for anything in the fume hood, or the fume hood. Anyone else in the room might want to be wearing ear protection. Maybe some unlucky shrapnel damage across a room, depending on what's around the source. The little CO2 cartridges are 8g, think of how big of a balloon one of those would fill at ambient pressure. Explosions are kinda (sorta) like filling up a balloon with gases equal to the mass of the explosives, but a lot faster, and with some extra heat, loud noises, and things being displaced very quickly. Each molecule of gas wants to take up about the same amount of space, regardless of their complexity or mass. So things that decompose into more simple molecules make better bangs (or better rocket fuels) than things that form fewer, more complex molecules. If you can visualize a chunk of liquid/solid CO2 becoming a balloon of gas, you can extrapolate that out to explosives exploding. It's not precise in any way, but it's enough to figure out how fast you need to be running. jetz0r has a new favorite as of 08:27 on Aug 24, 2016 |

Basically 4 grams has tipped the scale of how much you don't want it to exist anywhere near you right before it decides the same, but the 'near you' is same room or closer, not same building. You definitely don't want to be handling it with anything you'd like to keep in one piece.

My school has been cleaning out the metalwork store in recent weeks in preparation for an auditor to come out and give the school an ok as a whole. While nothing terribly FOOF worth have been found we did discover that there where multiple tins of paint that are lead based along with a pile of enamelling powders that are also lead based. What started the whole clean up in the first place was a bottle of sulphuric acid that escaped the bottle and ate through the shelf it was sitting on. Also on that shelf where a stack of other non properly stored bottles of chemicals that probably wouldn't have played nice if they had escaped their storage containers.

Fun thing about sulfuric acid is it doesn't evaporate. So it can sit for years until some poor doofus wipes it up with a paper towel barehanded.

Most of the hazmat symbols on rail tankers or trucks are pretty boring. Oxidizer usually means fertilizer. Corrosive is bleach and maybe HCl if you're lucky. Batteries on trucks. Flammable is a petroleum product that's probably oil, diesel, or gasoline. poo poo gets shipped all over the country all the time without incident. Problems usually arise because someone somewhere skipped a safety step and every safety measure failed as a result. Really nothing to worry about once you consider the nasty junk that goes into making literally everything. Still haven't topped seeing a liquid fluorine truck and I don't really want to.
