The amount of phosgene (COCl2; preferred IUPAC name: "carbonyl
dichloride") required to be in trouble is: "If you can smell it,
you're already in the zone of 'oh hey look at the time, it's emergency
room o'clock.'" (The concentration at which it can be smelled is four
times larger than the concentration needed to actually start having
adverse health effects.)

Aside: Phosgene is not the same as mustard gas (C4H8Cl2S; preferred
IUPAC name: "1-Chloro-2-[(2-chloroethyl)sulfanyl]ethane"). Phosgene is
actually mildly useful as a reagent in producing polyurethanes and
polycarbonates. Mustard gas is... well other than horrifically maiming
people (which it's great at) it's pretty useless; though one of the
related nitrogen mustard agents (specifically HN2, C5H11Cl2N;
preferred IUPAC name
"2-Chloro-N-(2-chloroethyl)-N-methylethan-1-amine"; which is also
great at horrifically maiming people) did end up becoming the first
ever chemotherapy drug: mustine. (Those must have been fun
conversations with your doctor. "So you have cancer." "Oh no." "But
there's a cure." "Oh yay." "It involves injecting you with mustard
gas." "...")
