Properly fighting small fires

Fire extinguishers are designed to fight fires in their early stages when the fire presents a relatively small hazard. An extinguisher can be used when the fire possesses the following characteristics:
  • Small
  • Slow growing
  • Giving off minimal smoke
  • Emitting minimal heat
If a fire is too large, if there is too much smoke or if you are too frightened, evacuate immediately. PASS Use the PASS method: P=Pull 
  • The safety pin is usually held in place by a plastic seal and will pull off. Do not push down on the operating lever while pulling the pin, it won’t come out.
  • Aim at the base of the fire, the lowest flame closest to you. The base of the fire will recede from you as you use the extinguisher, so you must adjust your aim.
  • The operating lever is above the carrying handle. The operating lever opens the valve when you squeeze it down. When you let go, the valve closes and the discharge stops
  • Sweep the nozzle by moving your arm at the elbow. Direct the discharge to cover the entire width of the base of the fire.
