How it's used
Beyond the literal meaning of toxic chemical vapors, this term is frequently used in casual conversation to describe an extremely unpleasant or suffocating smell, such as a foul odor in a room or from a person. It carries a hyperbolic tone when used to complain about bad air quality or body odor. It is not used to describe actual chemical warfare agents in a formal or military context, where more technical terms are preferred.
Examples
It smells like there is poison gas here, it stinks.
The factory is leaking poison gas, everyone hurry and leave.

Common mistake
Do not confuse this with 毒氣室, which specifically refers to a gas chamber. Using this word to describe a simple bad smell is common, but it is quite strong and implies the air is physically harmful or unbearable.
