So my team lead ordered a bottle of a particularly nasty chemical (don’t remember what, this was long ago) Thing is, he went on holiday immediately after and didn’t tell anyone about it. The bottle had to be shipped and kept at -20℃ otherwise it would decompose into a deadly gas; one of those lovely CMR types. So next thing that happens is, I get called on my day off by the boss saying that there is a scary box in the lab and if I could check it out. I was reluctant but I figure I’ll check it out. I though to myself that it was a little unusual that they would ship it in a styrofoam box without any dry ice (it had evaporated) so I take out a slightly bloated bottle which seems to be filled with some liquid. I then tear of the package label and read the MSDS. At this point I read all the scary labels and realize that this thing has been out here for a while, all the dry ice has evaporated, the bottle is bloated and filled with gas which I am sitting right next to. So I turn on ventilation and GTFO. I inform the boss who immeditally got his home freezer to cool it down. I meanwhile started to notice a stinging in my eyes (which was one of the effects) We wash out my eyes, stinging goes away, lungs are fine and everything ends without injury.
TLDR
Coworker orders deadly chemicals, goes on holiday, doesn’t tell anyone, almost kills me.
I’m actually genuinely interested as to why you use them.
