Least not on the eyes or mouth.

Wait, how so? I know zero about gas masks, so how does one identity that?

He has (at least what looks like from a distance) a fully sealed face mask on so no gas particulates can enter his eyes or get on his facial tissue plus he’s wearing a respirator with (again from a distance) filter cartridges that are rated to stop aerosolized acids and other such things.

Ah, thanks!
