Why Fire Extinguisher Knowledge Matters

Knowing the right type of fire extinguisher for different fire scenarios can make a significant difference in an emergency. Each type is designed to combat specific classes of fires, and using the wrong type can be ineffective or even dangerous.

Fire Extinguisher Classes and Types

1. Class A Fire Extinguishers: Class A extinguishers are designed for fires involving ordinary combustibles such as wood, paper, cloth, and plastics. They work by cooling the fire with water or extinguishing it with foam.

  • Uses: Offices, schools, homes, and general commercial buildings.
  • Types: Water, foam, and multi-purpose dry chemical extinguishers.

2. Class B Fire Extinguishers: Class B extinguishers are used for fires involving flammable liquids like gasoline, oil, grease, and solvents. These extinguishers smother the fire by cutting off its oxygen supply or interrupting the chemical reaction.

  • Uses: Kitchens, garages, workshops, and industrial facilities.
  • Types: CO2, dry chemical, and foam extinguishers.

3. Class C Fire Extinguishers: Class C extinguishers are designed for electrical fires involving energized electrical equipment such as wiring, circuit breakers, machinery, and appliances. They use non-conductive agents to extinguish the fire without the risk of electrical shock.

  • Uses: Offices, server rooms, electrical installations, and homes.
  • Types: CO2 and dry chemical extinguishers.

4. Class D Fire Extinguishers: Class D extinguishers are used for fires involving combustible metals such as magnesium, titanium, potassium, and sodium. These fires require a special extinguishing agent that separates the fuel from the oxygen and cools the material.

  • Uses: Laboratories, factories, and metal workshops.
  • Types: Dry powder extinguishers specifically designed for metal fires.

5. Class K Fire Extinguishers: Class K extinguishers are specifically designed for fires involving cooking oils and fats. These extinguishers work by saponification, which turns the burning oils into soap, effectively smothering the fire and cooling it down.

  • Uses: Commercial kitchens, restaurants, and cafeterias.
  • Types: Wet chemical extinguishers.
