[QUOTE="KarlVP, post: 779300, member: 16136"] Partly correct. [b]A[/b] is combustable materials. Anything that leaves an ash. [b]B[/b] is liquid fires. [b]C[/b] is electrical fires. But once power is disconnected, these become A fires. You need an extinguisher that is ABC rated for maximum efficency. The problem with Co2 extinguishers, is they do not prevent reflash of the fire. So if the material is hot enough, after the Co2 dissapates, the fire will re start. Dry Chem is better because it breaks down the reaction of the fire and doesn't allow it to reflash. It's like throwing a wet blanket on a fire. Halon replaces the oxygen in a fire with halon, which doesn't burn. It's fairly bad for the environment. Best fire extinguisher? An ABC. Bigger the better. The way I see it, the worst situation would be a human covered in fuel burning. (Screaming Alpha fire) get one that you can put that out with. Don't go out and get one of those little tiny auto parts store extinguishers. While they look cool, they only have about one second of agent in them. Not enough to do anything but cool your crotch after you spill hot coffee in it. Give Evergreen Fire and Safety a call. You can get a good sized extinguisher for less than $30. Well worth it.
