Do you know how to use a fire extinguisher? Many of us have learned the P.A.S.S. acronym for usage – Pull the pin, Aim at the base of the fire, Squeeze the trigger, Sweep from side to side. However, this is not all you need to know. There are also different types of fire extinguishers, all of them meant for a different type of fire.
Fires are classified as one of 5 types: Type A fires are regular fires in wood and similar materials. Type B fires are in flammable petroleum based liquids. Type C fires are electrical. Type D fires are in combustible metals like magnesium and potassium. Type K fires are usually in kitchens in vegetable oils or animal fats.
On fire extinguishers you will usually find a listing of what types of fires they are meant for. This is important to pay attention to, since using the wrong kind of extinguisher could make the fire worse, or cause you personal injury.
