Fire Extinguishers

A fire extinguisher can help you put out a small fire before it turns into a large one. Read the instructions and use the correct type of extinguisher for the fire you are fighting. If you use the wrong type of extinguisher, you can endanger yourself and make the fire worse.

Types of Extinguishers:

  • Class A: fires started with paper, wood, drapes and upholstery.
  • Class B: fires originating from fuel, oil, paint, grease, and other flammable liquids.
  • Class C: fires started with wiring, fuse boxes, conductors, and other electrical sources.
  • Class D: dry powder extinguisher to fight certain metals such as magnesium and sodium.

Extinguishers rated ABC Multipurpose provide the required protection for most types of fire.

Numbers are also used for Class A and B fire extinguishers. The larger the number, the larger the fire the extinguisher can put out. 

Buying and maintaining an extinguisher:

  • The extinguisher should be labeled by the Underwriter’s Laboratories of Canada (ULC).
  • Recharge it after use.
  • Store it near an exit and away from any source of heat or fire.
  • Keep it in plain view and out of reach of children.

Remember P-A-S-S:

  • Pull out the locking pin, breaking the seal.
  • Aim the nozzle at the base of the fire about 3 meters from the fire.
  • Squeeze the trigger handle all the way, the release the extinguishing agent. 
  • Sweep the contents of the extinguisher from side to side, moving front to back, across the base of the fire until it appears to be out

Only fight a fire if:

  • the fire is small and not spreading
  • occupants have been alerted and have left or are leaving the building
  • 9-1-1 has been called
  • you have a clear escape route that won't be blocked by fire
  • you know how to operate your extinguisher

Don't fight a fire in any other circumstance. Leave the premises immediately, close off the area and call 9-1-1 from a neighbour's house.

How many fire extinguishers do I need?

Assess your needs and provide accordingly. Place an extinguisher in the kitchen which has many ignition sources. If you have a wood burning stove or a fireplace, place an extinguisher between the hazard and the exit, so you never get trapped when retrieving your extinguisher.
