The P.A.S.S. Fire Extinguisher Method

Start with a safe setup

Alert others and call 911 before attempting to fight a fire. Position yourself with the exit behind you so the fire cannot cut off your way out.

P: Pull the pin

Hold the extinguisher upright, break the tamper seal, and pull the safety pin. The pin prevents accidental discharge during normal handling.

• Read the label before using the unit if time permits.
• Keep the nozzle pointed away from people.
• Do not test-fire the extinguisher in a hallway or work area.

A and S: Aim and squeeze

1. 1Aim low — Point the nozzle or hose at the base of the fire, where the fuel is burning.
2. 2Squeeze the handle — Press the operating lever steadily to release the extinguishing agent.
3. 3Control the discharge — Use short, deliberate movement rather than spraying above the fire.

For a liquid fire, avoid blasting directly into the liquid hard enough to splash it. Aim at the near edge and let the agent cover the fuel surface.

S: Sweep across the fuel

Sweep from side to side at the base until the flames are down. Continue briefly over hot spots, then back away while watching for re-ignition.

• Move toward the fire only if it is shrinking.
• Keep the exit in view.
• Leave immediately if the agent runs out before the fire is controlled.

After the extinguisher is used

Evacuate the immediate area and let the fire department assess the scene. Dry chemical residue can damage equipment and should be cleaned safely after responders release the area.

Common questions

What does P.A.S.S. stand for?

Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep side to side.

Should I aim at the flames?

Aim at the fuel at the base of the flames so the agent interrupts the fire where it is burning.

What if the fire comes back?

Leave the area, keep others out, and wait for the fire department. Do not assume a re-igniting fire is safe to fight.
