I think this could be a large untapped market, potentially.  I asked about buying a gas mask at Home Depot and all they had were flimsy respirators for painting and stuff, which would obviously melt as soon as lava hit them.  And nothing at all in the way of lava-proof suits.

I did buy a big piece of rebar, though, which I hit people with who come into my yard.  So I don't need a baton or anything like that.
