Agree. Our most likely fire is B (gasoline, etc) or C (electric) as stated. "A" would be small to start with, we are not an 18 wheeler with a tire fire. Anyway, water is the best thing for A, even if it's a ditch of water. C is usually going to be preceded by the smell or something not working, or smoke getting out of the wires. That's what the ignition switch or master battery disconnect are for, and the dry chemical BC if needed. B is the only one that really scares me and the BC is fine for that. If the one on the car is not enough, hopefully help arrives with another. Been on both ends of that. (IMHO, US DOT & WSO Safety & Security Director, ret.)
