Most portable extinguishers are rated for use with more than one classification of fire. An example would be a commercial kitchen similar to those found in restaurants and cafeterias.

Extinguishing a flammable gas fire, without shutting off the fuel, will allow unburned gas to escape into the atmosphere, which may permit a dangerous accumulation of gas to develop, and an explosion may occur if the gas is exposed to an ignition source. In fact, if the only fuel burning is the leaking gas, the best method for extinguishing the fire is to shut off the fuel supply. Note: Do not attempt to extinguish a fire involving flammable gas unless there is reasonable assurance the source of fuel can be promptly shut off.
