"Excuse Me Sir, Would You Like to Buy a Kilo of Isopropyl Bromide?"

Chemophobiacs may remember Edward Tyczkowski, featured here in a breathless Salon article: https://www.salon.com/2004/03/23/armageddon/
He was a very talented fluorine chemist, who ran a custom synthesis and contract research outfit out of a shed in the ghetto somewhere in the South. From colleagues who knew him I understand that he was a true gentleman and righteous. He wasn't known for mishaps, but when he retired he left behind cylinders of sulfur tetrafluoride (10 times more toxic than phosgene) and perfluoroisobutylene (100 times more toxic than phosgene, supposedly the Russians had a stash because it passes through your regular gas masks) and much other stuff.
A trained chemist knows how to use SF4 without incident (I have done so myself), but it's remarkable that Tyczkowski, who recruited his workers from the ghetto - Apartheid was strong in the 1960s Southern US, didn't have deaths amongst his workforce. It shows what properly training one's workforce can do. Meanwhile Information Technology tries to achieve the perfect fit through endless rounds of interviewing and teambuilding and keeps failing.
About once a month they were spending a few thousand dollars on new tires for this brand new Kubota LA525. The tires would show excessive wear and, curiously enough, enormous golf ball sized holes that look like they were burned through with a torch. we all figured it was vandalism.
We'd recently unmounted one of the tires to replace it when a golf-ball chunk of white rock fell out and shot across the shop floor with a startling bang. Curious, I took it to our OSHA office and our inspector nearly screamed, 'Thats phosphorous!' Turns out the cemetery was built on an old lot used by a chemical transportation company. It also explained why the sod was being replaced about twice a year.
