I have some - and didn't get them until AFTER 9/11 - when I saw folks running through all that dust when the WTC's collapsed. Keep 'em in a BoB, so that if when the mohammedans knock over more buildings, I have a good DUST mask handy!
Lotta ASBESTOS was flying around that day - firefighters and police who were there that day, have come down with some serious respiratory problems since.
