Classes of Fire
All fire extinguishers are labeled using standard symbols for the class of fire they can put out. They should be installed in escape routes, near exits, and always in plain view. Keep extinguishers away from hazards.
- Class A Includes ordinary combustibles such as wood, cloth and paper.
- Class B Includes flammable liquids such as gasoline, oil and oil-based paint.
- Class C Includes energized electrical equipment such as wiring, circuit breakers, and appliances. When the power supply is interrupted to an electrical device, a class C fire can be considered as a class A fire.

Important points to remember
- Know when to go – a safe escape is the most important thing. Every household should have a home escape plan and working smoke alarms.
- Always test the extinguisher first to ensure it works before you approach a fire.
- Most extinguishers discharge completely in as few as eight to 30 seconds.
- The operator must have a clear escape route - install fire extinguishers close to an exit and keep your back to a clear exit when you use the device so that you can make an easy escape.
- Never put a fire between yourself and your exit.
- If the room fills with smoke, leave immediately.
- Only adults who know how to use portable fire extinguishers should operate them.
- Only buy an extinguisher that has been approved by a recognized testing laboratory such as U.L.C. or C.S.A.
