MaintainlyHow often should you check your fire extinguisher?
Check fire extinguisher once a month. The commonly recommended range is inspect monthly, service yearly. A discharged or expired extinguisher is useless in an emergency. This is a safety-critical task, so do not let it slip.
The monthly check is thirty seconds of looking, not a service. You are confirming three things: that the extinguisher is where it should be, that the gauge reads in the green, and that nothing has obstructed it since last month.
Why does checking your fire extinguisher matter?
A discharged or expired extinguisher is useless in an emergency.
What happens if you skip checking your fire extinguisher?
An extinguisher that has lost pressure, been damaged or been buried behind boxes fails at the one moment you reach for it, when there is no time to discover a problem. The US Fire Administration’s advice is to use one only on a small, contained fire, after others have been alerted and the fire department called. Otherwise leave.
How do you do it?
- Confirm it is in its place and unobstructed. Extinguishers migrate. Check nothing is blocking or limiting your ability to reach it.
- Read the pressure gauge. The needle should sit in the green band. A reading that is too high or too low means it needs service or replacement.
- Check the pin and tamper seal. The pin should be in place and the seal unbroken. A broken seal means it may have been used or tampered with.
- Look over the body and hose. The US Fire Administration says to make sure the can, hoses and nozzles are not damaged, dented or rusted.
- Wipe it clean and follow the label. Remove any dust, oil or grease from the outside. Some extinguishers need to be shaken monthly and others pressure tested every few years, so do what the label on yours says.
- Note the date. Record the check, along with any service or expiry date printed on the label.
What does it take?
How do you know checking your fire extinguisher is overdue?
- The gauge needle outside the green band
- A broken or missing tamper seal
- Rust, dents or damage to the cylinder, hose or nozzle
What do people get wrong?
- Buying without reading the class label. The US Fire Administration lists Class A for ordinary materials like cloth, wood and paper, Class B for flammable liquids like grease and oil, and Class C for plugged-in electrical equipment; a multipurpose A-B-C unit can be used on most types of home fires
- Storing it under the sink behind the cleaning products, where you cannot reach it during a fire
- Attempting to fight a fire that is not small and contained: alert others, get out and call the fire service
- Treating the gauge as the whole check and never looking at the hose, the pin or the body
What changes how often you need to do it?
- Extinguishers in garages and workshops take more knocks, so look them over with extra care
- Service and replacement intervals differ by model; the label on yours is the rule to follow
- After any use at all, however brief, it must be recharged or replaced
When should you stop and call someone?
Recharging, pressure testing and any unit with a gauge outside the green go to a fire equipment service company. Do not attempt to repressurise one yourself.
Does this differ in the US, UK, Australia or Canada?
United States
For workplaces, the federal OSHA standard requires portable extinguishers to be visually inspected monthly and given an annual maintenance check. That rule covers employers rather than private homes, but the same rhythm is a sensible one to copy. The US Fire Administration says extinguishers labelled A-B-C can be used on most types of home fires.
United Kingdom
Fire and rescue services publish their own advice on whether a home is better served by an extinguisher, a fire blanket or neither, so check your local service’s guidance. If you rent, or live in a building with shared areas, ask the landlord or managing agent who maintains any equipment provided.
Australia
State and territory fire services publish advice on extinguishers and fire blankets for homes, including which type suits a kitchen. Check your own service’s guidance, and follow the maintenance instructions on the label.
Canada
Check your local fire department’s guidance on the type and size to keep at home. In apartment and condo buildings, equipment in shared areas is the building owner’s to maintain, so report a missing or damaged unit rather than servicing it yourself.
