How to Put Out a Small Fire Safely
A portable extinguisher is for a small, contained fire and a clear escape route. Your first job is to alert others and call 911, not to protect property.
Make the decision before you approach
Only consider using an extinguisher if the fire is small, you understand what is burning, the room is not filling with smoke, and the exit remains behind you. If any of those conditions changes, leave.
- Activate the alarm or tell others immediately.
- Call 911 or assign a specific person to call.
- Keep a clear path between you and the exit.
- Use an extinguisher rated for the fuel involved.
Choose the right extinguisher
An ABC dry chemical extinguisher handles ordinary combustibles, flammable liquids, and energized electrical equipment. A commercial kitchen grease fire calls for a Class K wet chemical extinguisher after the hood system operates.
Use the extinguisher from a safe position
- 1Stand back — Start several feet away, with the exit behind you and smoke moving away from your path.
- 2Aim at the fuel — Direct the agent at the base of the flames, not at the smoke above them.
- 3Discharge in a controlled sweep — Move side to side across the burning material and watch for the flames to collapse.
- 4Back away after the fire is out — Do not turn your back. Leave the area and wait for the fire department to say it is safe.
A discharged extinguisher is no longer ready for the next emergency, even if it still feels heavy. Tag it out of service and arrange prompt recharge or replacement.
Watch for re-ignition
Hot material, hidden fuel, or a leaking liquid can restart a fire after the visible flames are gone. Do not resume work just because the room looks clear.
- Keep people away from the area.
- Close doors if you can do so safely.
- Do not reset alarms or suppression equipment.
- Meet responders and explain what burned and what agent was used.
Prepare your team before an emergency
Employees should know extinguisher locations, the alarm procedure, the evacuation route, and that evacuation comes before firefighting. Practice with an instructor instead of learning during an incident.
Common questions
- Should I always try the extinguisher first?
- No. Sound the alarm, call 911, and evacuate if the fire is growing, smoky, unfamiliar, or blocks your exit.
- How close should I stand?
- Start at a safe distance stated on the extinguisher label, then move closer only as needed while keeping the exit behind you.
- Can I use an extinguisher more than once?
- After any discharge, have it serviced or replace it before returning it to service.
