Chemical Hazards and Safety

It's probably going to be more dangerous to the amature chemist than thier intended victim.

Dont forget the chemicals that would also hurt your hands.

You will be absolutely fine, you really don't have to worry about it. It's very uncertain whether ingesting these chemicals is harmful, touching them briefly is just fine.

I want to point out from professional experience that the dangers of HF as stated in this article are not embellished in any way. It is really the stuff of nightmares.Also it's pretty insane IMO to put it in a bottle labeled 'rust remover'. That's bound to cause accidents like this with people thinking it's just any old stain-away soap.

It absolutely was and is. The "potential to produce toxic gases" thing the article mentions is very well known, though the usual advice to avoid it (never mix two different cleaners) was briefly a little more difficult to practice due to shortages.

Yikes. I wonder what was the nature of the work being performed. Perhaps they were working with volatile solvents?

There is a "chemicals I won't work with" on HF

Beware of toxicity of unknown conductive sprays, especially in enclosed spaces.

Or maybe heavy metal poisoning. Chemistry can be dangerous.

How dangerous is to keep lot of it in a tank in case of a leak?
