Why do Shoes roam around the boat in polyester coveralls when "everyone is a firefighter?" Logic is not their forte.
Yeah, I'm pretty sure the regular coveralls are "fire resistant." If you're talking about the engineering coveralls, I'm pretty sure those are even more fire resistant, other than the glaring flaw of having a pocket flap that goes all the way through.
And if you're fighting a no shit fire, that's what an FFE is for.
