How To Use A Fire Extinguisher: The PASS Method (Step-By-Step)
When a fire breaks out, you have 30 seconds to act before it doubles in size. Here\u2019s the PASS method, the modern aerosol method, and the mistakes that get people killed.
Use the PASS method: Pull the pin, Aim at the base of the flames, Squeeze the handle, Sweep side to side. For modern aerosol extinguishers like the LifeSafe StaySafe All-in-1, the simpler method is: Twist the cap, Aim at the base, Press and spray. Always evacuate first if the fire is bigger than a wastebasket.
Before You Try To Fight A Fire — Decide If You Should
Most fire-safety advice skips the most important question: should you fight this fire at all? Misjudging this is how people die in house fires. The general rule from fire services worldwide: if the fire is larger than a wastebasket, contained to one item, and your evacuation route is behind you — fight it. If anything else is true, leave.
Time matters. Fires double in size every 30 seconds. By 90 seconds, a small contained kitchen fire becomes an unrecoverable house fire. If you decide to fight, you have less than a minute. Do it right, do it fast, or get out.
Always do these things first, in order: get others out of the building, call emergency services, then fight the fire only if it's safe. Never reverse this order. The fire doesn't care that you grabbed your extinguisher fast if you didn't call the fire service to back you up.
\u2705 FIGHT THE FIRE IF:
- \u2022It’s smaller than a wastebasket
- \u2022It’s contained to one item
- \u2022Your exit is behind you
- \u2022You’ve already called 911 / 999
- \u2022You’re trained on the extinguisher you’re holding
\u274c DO NOT FIGHT IF:
- \u2022Flames are above your head
- \u2022Smoke is filling the room
- \u2022The fire blocks your exit
- \u2022You’re alone with no one knowing you’re inside
- \u2022You don’t know what’s burning
THE PASS METHOD
For traditional pin-and-lever fire extinguishers
PULL
Pull the pin
Pull the safety pin straight out from the handle. This breaks the tamper seal and arms the extinguisher. The pin should release with moderate force — don’t twist it.
AIM
Aim at the base
Aim the nozzle at the base of the flames, not the flames themselves. The fuel is at the base — that’s what you need to suppress. Stand 6–8 feet away.
SQUEEZE
Squeeze the handle
Squeeze the operating handle slowly and steadily. Don’t pulse — sustain the discharge. A typical home extinguisher empties in 8–15 seconds.
SWEEP
Sweep side to side
Sweep the discharge across the base of the fire in a steady side-to-side motion. Continue until the fire is fully out. Watch for re-ignition for at least 5 minutes.
The Modern Aerosol Method (For Twist-Cap Extinguishers)
Modern compact aerosol extinguishers like the LifeSafe StaySafe All-in-1 simplify the PASS method. There's no pin, no lever, no sweep — just three steps you can perform one-handed in under 5 seconds.
TWIST
Twist off the cap. The cap doubles as a tamper seal — twisting it off arms the unit instantly. No pin to fumble with.
AIM
Point the nozzle at the base of the flames from 3–6 feet away. Closer than traditional extinguishers because aerosol units have shorter range.
PRESS
Press and hold the discharge button. Continue spraying until empty. The unit empties in approximately 25 seconds.

Common Mistakes That Make Fires Worse
Most house fires that start as contained incidents become catastrophic because of one or more of these common mistakes. Knowing them in advance is half the battle.
Aiming At The Flames
Flames are the symptom, not the cause. Aim at the base where the fuel is.
Standing Too Close
You’ll be hit by flying embers, oil splashes, or pressure blowback. Stand at the recommended distance.
Using Water On Grease
Water on hot oil creates a fireball. Never use water or wet rags on a Class F/K fire.
Moving A Burning Pan
Carrying a burning pan to the sink is how kitchens become house fires. Leave it on the stove.
Not Calling 911 / 999 First
Even contained fires reignite. Always call emergency services before fighting the fire, not after.
Using The Wrong Class Extinguisher
An ABC dry-powder unit on a grease fire spreads burning oil. Match the extinguisher to the fire class.
What To Do After You've Used The Extinguisher
Putting out the fire isn't the end of the emergency. Here's the protocol fire services recommend for the minutes and hours after suppression.
Evacuate Everyone (If Not Already Done)
Even if the fire looks out, evacuate. Smoke and reignition are immediate risks.
Call 911 / 999 (If Not Already Done)
Fire services should always inspect after any fire. They confirm full extinguishment and check for hidden spread.
Watch For Reignition For 30+ Minutes
Most home fires reignite within the first 30 minutes after suppression. Stay vigilant.
Ventilate The Room
Open windows and doors to clear smoke and any extinguishant residue.
Replace The Extinguisher Immediately
Single-use units (like aerosol extinguishers) cannot be refilled. Refillable units must be professionally serviced before reuse.
