How to Use a Fire Extinguisher

Well you've made the decision to fight a fire. Now what?

Use the "P.A.S.S." System:

• P = Pull - Pull the pin on the extinguisher.

• A = Aim - Aim the nozzle at the base of the fire.

• S = Squeeze - Squeeze the handle.

• S = Sweep - Sweep the nozzle from side to side at the base of the fire.

Remember there are five classes of fire. Make sure you use the right kind of extinguisher for the fire you are going to fight. The wrong type of extinguisher can do more harm than good.
