Fire Extinguisher Types

Fire extinguishers are tools for the immediate squelching of flame as a means of self-preservation and fire prevention. They are not a substitute for emergency calls to the fire department, and they certainly do not supersede a properly maintained fire protection system.

No one type can be considered a “universal” fire extinguisher, and thus there are several fire extinguisher types.

 The type of fire hazard determines if you need a class A, B, C, D or K extinguisher for given use. When choosing a fire extinguisher for your home, office or other setting, bear in in mind what type of fire hazard you’re most likely to encounter before making your choice. A list of fire extinguisher types follows:

  • A class A fire extinguisher is for “ordinary” combustible materials, though this description is somewhat misleading. Paper, wood, and other flammable hydrocarbons are defined in this category as “ordinary.” At a glance, look for a green triangle.
  • A class B fire extinguisher is for extinguishing flammable liquids like gasoline or kerosene, and can also be used on cooking oils, although these are not considered kitchen fire extinguishers. Look for a red square.
  • A class C fire extinguisher is for electrical equipment and wiring. This includes appliances and computers. Class C extinguishers use non-conductive material to put out the fire. Look for a blue circle.
  • Class D fire extinguishers are unusual in home applications since they are for combustible metals like magnesium. They carry a yellow decagon as their symbol, and they’re mostly found in laboratory settings.
  • Class K fire extinguishers are, as their lettering suggests, for kitchens. Class K extinguishers are specially designed to be used on fats, oils, and the appliances they may be stuck in. Look for the distinctive black
