It is indeed fireproof, as is most webbing due to the different protein crystals being heat resistant. And actually, you could even line the web with Kevlar, which would pretty much delflect any high caliber round if it was used for chest armor, as the impsct would dissapate over the surface area of the body. I used steel here because is is malleable and is able to be molded into a mask shape.
