Why is phosgene the most dangerous gas?

User Avatar

Asked by Wiki User

Phosgene is certainly a dangerous gas, that was specifically designed to be poisonous to people, so that it could be used as a weapon of war, but it is not the most dangerous gas. Fluorine gas is more dangerous. But fluorine is so dangerous that it would not be practical to use it as a weapon (not that phosgene is a very practical weapon either; poison gas blows on the wind, and easily turns back toward the people who are using it). Anyone trying to use fluorine gas as a weapon would almost certainly wind up being killed by it. It is almost impossible to handle safely.
