That's the insidious thing about isocyanates--not that they're
immediately toxic but that when your system decides that it's had enough,
then you
can't even get _close_ to them. And when that point of sensitization
occurs seems to be random--one guy can spray his whole life without any
protection and never have a problem, another guy can get sensitized the
first time he forgets to wear his air mask.

It was a methyl isocyanate leak that killed over 2,000 people in Bhopal
India.

Enough of _anything_ will kill you outright. Most of us don't release 40
metric tons of pure isocyanate at one time.
