When to Fight a Fire
Fire extinguishers are designed for small, contained fires. Before attempting to fight any fire, you must make critical decisions quickly.
- Everyone is evacuating or has evacuated β Life safety comes first.
- The fire department has been called β Always call 911 first.
- The fire is small and contained β No larger than a small trash can.
- You have an escape route β Never let fire get between you and the exit.
- You have the right extinguisher β The wrong type can make fires worse.
- You know how to use it β No time to read instructions during a fire.
GET OUT if: the fire is spreading rapidly, there is heavy smoke, you're unsure what's burning, you don't have the right extinguisher, or your instincts say to leave. Your life is more valuable than any property.
Types of Fires
Fires are classified by the fuel that's burning. Using the wrong extinguisher can be ineffective or dangerous.
Ordinary
Wood, paper, cloth, trash, plastics
Liquids
Gasoline, oil, grease, paint, solvents
Electrical
Energized equipment, wiring, appliances
Metals
Magnesium, titanium, sodium (industrial)
Cooking
Cooking oils, fats in kitchens
ABC-rated extinguishers work on Class A, B, and C fires and are the most common for homes and offices. Check the label on your extinguisher to know what fires it can fight.
The PASS Technique
Remember PASS β the four steps to using a fire extinguisher effectively.
Pull
Pull the pin to break the tamper seal
Aim
Aim low at the base of the fire, not the flames
Squeeze
Squeeze the handle to release the agent
Sweep
Sweep side to side at the base until fire is out
- Stand 6-8 feet away β Move closer as the fire diminishes.
- Aim at the base β Spraying flames doesn't put out the fuel.
- Use short bursts β Most extinguishers last only 10-20 seconds.
- Back away facing fire β Watch for re-ignition as you leave.
Extinguisher Maintenance
An extinguisher that doesn't work when you need it is useless. Regular inspection ensures readiness.
- Accessible: Not blocked, visible, easy to reach.
- Pressure gauge: Needle in the green zone.
- Pin and seal: Pin in place, tamper seal intact.
- Physical condition: No rust, dents, or damage to hose/nozzle.
- Instructions: Label legible and facing outward.
Fire extinguishers should be professionally inspected annually. After any use (even partial), have it recharged or replaced. Most extinguishers have a 5-12 year lifespan.
Kitchen Fire Safety
Cooking is the #1 cause of home fires. Kitchen fires require special attention.
- Turn off the heat β If safe to do so.
- Cover with a lid β Slide a lid over the pan to smother flames.
- Leave it covered β Don't remove the lid or move the pan.
- NEVER use water β Water on grease fires causes explosive splashing.
- Use a Class K extinguisher β If available, or a Class B for small grease fires.
NEVER throw water on a grease fire β it will cause a violent fireball. NEVER try to carry a burning pan outside β you risk spreading fire and severe burns. If the fire spreads beyond the pan, evacuate and call 911.
