Fire Extinguishers

In 2019, fires caused more than $14 billion in property damage. Fire extinguishers, when used properly, can save lives and significantly reduce property damage. While all types of fire extinguishers are effective fire safety tools, they should only be used if a fire is contained to a single object and not spreading.

  • Types of Fire Extinguishers

    There are five types of extinguishers designed to put out the different types of fire classes. Knowing the different fire classes will help you determine which types of fire extinguishers to have available for use.

    The different fire classes are:

    • Class A: Ordinary combustibles such as cloth, wood, rubber paper and many plastics
    • Class B: Flammable liquids such as gasoline, oils, oil-based paint, alcohols, petroleum gases and tars
    • Class C: Energized electric equipment such as appliances, tools and computers
    • Class D: Combustible industrial metals such as sodium, lithium, titanium, magnesium and potassium
    • Class K: Cooking oils and greases such as animal and vegetable fats
  • Using a Fire Extinguisher

    After identifying the appropriate type of fire extinguisher to use, it is important to make sure you understand how to properly operate one. Become familiar with how to use a fire extinguisher before a fire occurs, and always remember to:

    • Use a fire extinguisher only when the fire is contained to a single object and not spreading.
    • Use a fire extinguisher that is large enough to put out a small fire, but not so heavy that it makes handling it difficult.
    • Store fire extinguishers next to exits to ensure the fire is not blocking a safe escape if it spreads.
    • Follow the word “PASS”:
      • Pull the pin at the top of the extinguisher that keeps the handle from being accidentally pressed.
      • Aim the nozzle toward the base of the fire, standing approximately eight feet away.
      • Squeeze the handle slowly and evenly.
      • Sweep the nozzle back and forth at the base of the fire.
