I wonder how
many accidental poisonings occurred?
A number, I would imagine, and especially in
tight quarters. I got
exposed to some briefly during the `40s when the paper wrapping on some
decorative steel plate caught fire and the people nearest used a Carbon
Tet extinguisher to put it out. Rather pungent as I recall, so it does
provide some warning. Also in that same era we used to degrease various
components of
Resnatron Radar jamming with carbon tet and acetone bare handed. No one
thought a thing of it except for the way it degreased your hide!
Acetone. The one
common solvent I hate to hell. It ripped apart the
supposedly-chemical-resistant gloves I was wearing while I was using it and
proceeded to cover my fingers in goop. Took me a week to get all the cack
off. "Chemical resistant" my left sock.
So what if I've chopped a year or so off my life expectancy? For that year
or so, I've had a lot more fun than some people twice my age... Including
making a "slugzapper" - a 150V low-current voltage source to keep the slugs
away from my Dad's flower bed :-)
Oh, then there was the time I "accidentally" made an EHT generator out of a
solenoid coil and a few diodes, transistors, etc... It was supposed to be an
LC oscillator...
Later.

'Fraid not. Carbon Tetrachloride is a liquid at normal temperatures and
used to be the fire extinguisher of choice in hand-pumped extinguishers
for mobile - read cars, trucks, and buses - use. Halon, on the other
hand, is a gas at normal temperatures and is actually breathable for
short periods.
