that is interesting reading indeed. what a tangled mess, it seems it's worse in California. bleah.
somewhere in the middle of the article he mentions supplying a fire extinguisher. definitely a good idea. but I wonder if 2A10BC really is the right thing for putting out APCP fires? surely something more specific would be better, the C (electrical) isn't really needed? (A is for "ordinary combustables, such as wood and paper"; B is for "flammable liquids, such as grease, gasoline, oil, etc.")
