  • Class B Gases and liquids that are flammable
    • Petroleum oil, gasoline paint, propane-butane
    • Not included in cooking oil.
  • Class C – Electrical equipment that is energized
    • Transformers, motors, appliances, and appliances
  • Class D – Combustible metals
    • Aluminum, sodium, potassium magnesium
  • Class K – Kitchen applications
    • Grease and cooking oils animal fats vegetable fats

Warning The use of an extinguisher that is not appropriate for the fire class could result in the flame growing, spreading, or even exploding.

Fire Triangle

The Fire Triangle is composed of heat, oxygen, and fuel, the three essential elements of a fire. If one or more of these elements are eliminated the fire could be slowed or quelled. Thus, every extinguisher aims to remove any one or more of these three elements.

    • Use for class B and C fires
  • Dry Chemical – Fire extinguishers are the standard ABC extinguishers that the majority of people know about. They are used to stop chemical reactions involving heat fuel and oxygen. The extinguishers also act as a barrier between oxygen and the fuel components within the triangle.
    • It is used on Class A, B, and C fires
  • Wet Chemical –  Fire extinguishers take heat out of the triangle, and prevent ignition by establishing barriers between oxygen and the fuel elements. They are typically employed to put out fires caused by grease inside commercial kitchens.
    • Use for Class A and K fires
  • Clean Agents – or Halogenated extinguishers stop the chemical reaction that occurs in the triangle of fire.
    • Use for class B and C fires
  • Dry Powder – Extinguishers that are like dry chemicals, except they operate by separating the fuel from oxygen, or by taking heat from the triangle of fire.
    • Use only on Classes D fires only
  • Water Mist – Extinguishers take the heat element from the fire triangle. They also are a good alternative to extinguishers that are clean when there is concern about contamination.
    • Use for Classes A and C-class fires
  • Cartridge Operating Dry Chemical – Extinguishers are generally used in harsh environments that require more durability than the typical extinguishers that are pressure dry.
    • Use for class B and C fires

Annual – Inspections every year are mandatory and require the inspectors to ensure that the extinguisher’s pressure is at a minimum and unaffected and is properly weighted. Inspections at the annual level also include a test of the pull of the pin and a replacement of the seal, as well as a current inspection tag. If the extinguisher does not comply with these standards then it should be replaced.

Six-Year Maintenance – Extinguishers that store the contents of a pressurized agent should be empty and replaced every 6 years. 6-year maintenance demands a careful inspection of both the exterior and interior and should be completed within 72 months of the date of manufacturing.
