Your Ultimate Fire Extinguisher Handbook
Attention Employers: Fire safety should be a top priority in your workplace, but life safety comes first. Only extinguish fires or use fire equipment when it is safe, and life is not at risk. When in doubt, get out.
Why is fire safety so important, you ask? Fires can occur unexpectedly and spread rapidly, causing devastation in a matter of minutes. Make sure your employees are trained on how to use a fire extinguisher and that your workplace has the correct fire extinguisher for specific hazards. Employers must implement a fire safety and emergency action plan, conduct regular drills, and prioritize fire extinguisher training. Remember, prevention is key.
Types of Fires and Extinguishers
Employees are never required to fight fires, but they should know how to use a fire extinguisher if they volunteer. Using a fire extinguisher by employees is voluntary. Understanding the different types of fires and fire extinguishers is crucial. There are five fire classifications, each requiring a different type of extinguisher. Let’s go through each:
- Class A Fire: Involves ordinary combustibles like wood, paper, or cloth. Use Class A extinguishers (water or dry chemical).
- Class B Fire: Caused by flammable liquids like gasoline or oil. Use foam or CO2 extinguishers.
- Class C Fire: Energized electrical equipment (appliances, wiring). Use CO2 extinguishers or ABC extinguishers (non-conductive agents to prevent electrical shock).
- Class D Fire: Combustible metals like magnesium. Use dry powder portable fire extinguishers.
- Class K Fire: Fueled by cooking oils or grease. Use wet chemical extinguishers for their cooling effect.
How to Use a Fire Extinguisher
Knowing how to use a fire extinguisher correctly can mean the difference between containing a small fire and a disastrous blaze. Remember the acronym P.A.S.S. to help you remember these steps:
- Step 1: Pull the pin from the top of the extinguisher.
- Step 2: Aim the extinguisher nozzle at the base of the fire. Do not aim at the flames.
- Step 3: Squeeze the handle to release the extinguishing agent.
- Step 4: Sweep the nozzle from side to side, aiming at the base of the fire, until it’s extinguished.
Common mistakes to avoid include using the wrong type of extinguisher, aiming at the flames instead of the base of the fire and not having the proper training to use a fire extinguisher effectively.

When to Use a Fire Extinguisher
Knowing when to use a fire extinguisher is just as important as knowing how to use it. Attempting to extinguish a fire can be dangerous and potentially life-threatening, so it’s essential to make the right decision.
The first step in deciding whether to use a fire extinguisher is to identify the fire hazard. If the fire is too large or spreading, an employee shouldn’t attempt to extinguish it. Instead, they should evacuate the area immediately and call the fire department.
Do not enter an enclosed area, blocked area or corner to extinguish a fire.
If the fire is smaller than a wastebasket and contained, and you have the appropriate type of extinguisher, then a trained employee can attempt to extinguish the fire. Do not attempt to extinguish a fire larger than a waste basket.
It’s essential to discuss the rules for using a fire extinguisher with all employees and make sure that everyone knows how to use one. To help, here’s a quick list of the safety tips above:
● Only tackle fires smaller than a wastebasket.
● Ensure you have the right fire extinguisher for the fire class.
● Never enter enclosed spaces or block exits.
● If in doubt, evacuate and call the fire department.
