How to Use a Fire Extinguisher

PASS (Pull – Aim – Squeeze – Sweep)

  • Pull the safety pin at the top of the extinguisher (some units have latches or levers instead)
  • Aim the nozzle, horn, or hose at the base of the flames. Hold the extinguisher vertically to ensure the unit will have enough pressure
  • Squeeze or press the handle to release the extinguishing agent. Always read manufacturer’s directions for your particular model
  • Sweep from side to side at the base of the fire and at least six inches past the edges of the flames until completely extinguished
What Type of Fire Extinguisher Do I Need?

Every type of extinguisher is designed to fight a certain class or classes of fire. There are four classes which are determined by the type of fuel. Learning to identify these classes will help you select the right fire extinguisher. Using the wrong type of fire extinguisher can cause a fire to spread and place you in greater danger.

There are also multi-purpose fire extinguishers that can be used on types A, B, and C classes of fire. Select the most appropriate types of fire extinguishers for your needs, and learn which type of extinguisher can be used on each class of fire.
