What unique toxic gas test must be conducted for Class Bravo fires?

Explanation:
In Class Bravo fires, the main atmospheric danger comes from the vapors of the flammable liquid itself. The test that’s uniquely important is to monitor for hydrocarbon vapors in the air. Detecting hydrocarbons lets you judge whether the atmosphere is still hazardous for entry, and it guides your ventilation and suppression decisions to keep people safe. The other gases listed—chlorine, ammonia, and phosgene—aren’t the specific, defining toxic-gas concern for a hydrocarbon fire, even though they can be present in other contexts.
