A minor spark could start a fire?
Bob, I'll concede that polystyrene is flammable, but if you've ever tried to burn the stuff you'll realized it's kinda hard to get it burning. It melts and pulls away from the source of heat.
If it was as flammable as you're suggesting, it wouldn't be used as insulation in virtually all of the flat roofs on the continent.
