The PASS Technique: How to Use a Fire Extinguisher
In an emergency, you won't have time to read instructions. Learn the PASS technique now so it becomes muscle memory when seconds count.
PASS in 10 Seconds
When NOT to Use an Extinguisher
Before attempting to fight any fire, ensure these conditions are met. If ANY are false, evacuate immediately.
- Fire is larger than a small trash can
- You don't have a clear escape route behind you
- The room is filling with smoke
- You're unsure what type of fire it is
- The fire has spread to multiple areas
PASS: Step-by-Step Guide
PULL
Pull the pin at the top of the extinguisher
- Break the tamper seal
- The pin keeps the handle from being accidentally pressed
- Don't squeeze the handle until you're ready
If the pin won't come out, twist and pull. Some have plastic seals that need to break.
AIM
Aim the nozzle at the BASE of the fire
- Not at the flames – at the source
- Stand 6-8 feet away (farther for larger fires)
- Keep the extinguisher upright
Aiming at flames wastes agent. The base is where the fuel is burning.
SQUEEZE
Squeeze the handle to discharge the agent
- Apply steady pressure
- The discharge will begin immediately
- Control the flow with handle pressure
You can release the handle to stop the flow – useful for conserving agent.
SWEEP
Sweep side to side across the base of the fire
- Cover the entire base of the fire
- Move closer as the fire diminishes
- Continue until completely extinguished
Sweep motion prevents fire from outflanking your coverage.
Common Mistakes to Avoid
Even with training, panic can lead to errors. Knowing these common mistakes helps you avoid them under pressure.
Standing too close
Why it's dangerous: The spray pressure can spread burning material
Instead: Start 6-8 feet back, move closer as needed
Aiming at flames instead of base
Why it's dangerous: Wastes extinguishing agent without cutting off fuel
Instead: Always aim at the base where fuel meets fire
Turning your back on the fire
Why it's dangerous: Fire can re-ignite or spread behind you
Instead: Back away facing the fire, watch for re-ignition
Using wrong extinguisher type
Why it's dangerous: Water on grease = explosion; CO2 on paper = ineffective
Instead: Check labels, use ABC for most situations
Staying too long
Why it's dangerous: Smoke inhalation, fire growth can trap you
Instead: If not out in 30 seconds, evacuate immediately
LifeSafe's "Deodorant-Style" Operation
LifeSafe and similar aerosol extinguishers operate differently than traditional units. There's no pin to pull—just aim and spray like a can of spray paint.
Modified PASS for LifeSafe
Important Difference
LifeSafe has shorter spray distance (6-8 ft vs 10-15 ft) and limited capacity. You may need to get closer, which means being more certain the fire is small enough to handle safely.
Special Considerations: Seniors & Limited Mobility
Traditional fire extinguishers can be challenging for those with limited grip strength, mobility issues, or who have never used one before. Here are adaptations:
Physical Adaptations
- • Consider lighter aerosol-style units (LifeSafe, Element)
- • Practice removing the pin before an emergency
- • Position extinguisher at waist height for easy grab
- • Two-hand operation is fine for traditional units
When to Skip Fighting
- • Mobility limits quick escape? Don't engage
- • Can't lift the extinguisher? Evacuate
- • Vision impaired? Call 911, evacuate
- • Any doubt about ability? Get out first
Recommendation for Seniors
The LifeSafe StaySafe 335ml is our top recommendation for elderly users due to its light weight (600g) and one-hand operation. The simplified operation reduces confusion under stress.
Practice Techniques Without Waste
You don't need to discharge an extinguisher to practice the technique. Here's how:
Dry Practice Drill
- 1Walk to your extinguisher, pick it up (feel the weight)
- 2Practice removing the pin (don't actually pull it)
- 3Position yourself 6-8 feet from an imaginary fire
- 4Practice the sweeping motion while saying "base of the fire"
- 5Practice backing away while keeping the extinguisher aimed
Some fire departments offer free hands-on training where you can practice on controlled fires with expired extinguishers. Call your local department to ask.
The Bottom Line
Remember PASS: Pull, Aim (at base), Squeeze, Sweep
When in doubt: Evacuate first, call 911, let professionals handle it
