The thing I hated the most in the lab was having to constantly deal with formaldehyde - a pretty potent carcinogen. It's used in tissue preservation, so anytime you want to extract some DNA/RNA from formalin fixed paraffin embedded (FFPE) tissue you end up getting a dose of it.

The strangest thing is how in our chemistry labs all the waste chemicals from all our experiments had to be put into one big jar, so there would be this viscous, almost gooey mass of this silvery-orange-black'ish sort of toxic waste which was a combination of all the 30-40 different (already toxic) chemicals put together. That would then need to sit in the lab for a month until waste collection day arrived.

Due to one absent-minded, japanese, 60-year old woman, I inhaled SO3. It wasn't pleasant...

Interesting. Shouldn't this be * geek?

Wow... I would have raged.

I would have, except my lungs were in pain and I had to go home and rest.

Comment hidden because you are ignoring dag.(show it anyway)

Interesting that no one mentioned radioactives. Probably because the biggest danger about them is the fear of them. These guys wouldn't be afraid of a little plutonium.

Yep I was surprised they didn't talk to uranium boy for this one. Maybe they agreed amongst themselves not to spread radioactive fear. Or maybe the exhaustive controls they have around radioactive materials means that it generally isn't a danger feel about it. Or maybe it's their limited access to anything that is ...dangerously.. radioactive. I think probably the last reason is correct.

I'm not a chemist, but this is quite interesting.

It's creeping death.

nitric acid was my must dangerous

Yeah... still dealing with this myself in lab. Its so commonly used that people just messily use it like its sucrose or something.

National Toxicology Program 'Report On Carcinogens, Twelfth Edition (2011)'
pg.195
"Formaldehyde is known to be a human carcinogen based on sufficient
evidence of carcinogenicity from studies in humans and supporting
data on mechanisms of carcinogenesis. Formaldehyde was first listed
in the Second Annual Report on Carcinogens in 1981 as reasonably
anticipated to be a human carcinogen based on sufficient evidence
from studies in experimental animals. Since that time, additional
cancer studies in humans have been published, and the listing status
was changed to known to be a human carcinogen in the Twelfth Report on Carcinogens (2011)."

I think the reason why no one said any of the radioactives is because they're stable. You can deal with the radiation easily. Something that becomes sulfuric acid on contact with the water in the air, or poisonous and unstable materials, the unknown factor, I think is what makes them jump a little.

Yep. They have discussed in previous videos though the only kind of radioactives they get to deal with are really weak.
