Fire Extinguisher Monthly Check: A Two-Minute Routine
By Fire Safety BD · Last updated
What to look at each month — gauge, pin, seal, hose and body — and when the extinguisher needs a service technician instead.
An extinguisher that hangs on the wall for years is easy to forget. A quick look once a month tells you whether it will work on the day you need it.
The monthly look
- Place — it is where it should be, easy to see and nothing is stacked in front of it.
- Gauge — the needle sits in the green zone. (CO2 extinguishers have no gauge; they are checked by weight.)
- Pin and seal — the safety pin is in place and the tamper seal is unbroken.
- Hose and nozzle — no cracks, and nothing blocking the opening.
- Body — no dents, rust or leaks, and the label can still be read.
- Service tag — the last service or refill date is still within its period.
Write the date and your initials on the tag or in a log. A record makes it obvious when a month has been missed.
When to call a service provider
- The gauge needle is in the red, low or high.
- The pin or seal is missing — treat the unit as possibly used.
- There is visible damage or corrosion.
- The unit has been discharged, even briefly.
- The service date has passed.
Extinguishers are usually given a full service by a competent technician about once a year. Follow the period on the service tag and the manufacturer's label.
Keep it reachable
Mount the extinguisher on a bracket, stand or in a cabinet near the exit route, and mark the spot with a location sign so it can be found through smoke or by someone new to the building.
This is general guidance for routine visual checks. It does not replace professional servicing.
Frequently asked questions
How do I check a CO2 extinguisher that has no pressure gauge?
A CO2 extinguisher is checked by weight. Compare its weight with the full weight marked on the cylinder; a clear loss means it needs to be refilled by a service provider.
Does an extinguisher need refilling if it was used only for a second?
Yes. Once the seal is broken an extinguisher can slowly lose pressure, so it should be refilled or replaced after any use, however short.
