| Unlike people, all portable fire extinguishers are not created equal. The different letters on the labels indicate the types of fires they extinguish.
- Class A extinguishers are for fires that involve combustible materials such as cloth, wood, paper, rubber, and many plastics.
- Class B extinguishers are for fires that involve flammable and combustible liquids such as gasoline, alcohol, diesel oil, oil-based paints, lacquers, and flammable gases.
- Class C extinguishers are for fires that involve electrical equipment.
- Class D extinguishers are for fires that involve combustible metals such as magnesium, titanium, and sodium.
- Class K extinguishers are for fires that involve vegetable oils, animal oils, or fats in cooking appliances. These are mainly for commercial kitchens, like those found in restaurants, cafeterias, and caterers.
Most portable fire extinguishers are rated ABC, which means they are well suited for fires that occur in the home. If you work with metals, or cook for large crowds, consider adding class D and K extinguishers to your arsenal.
