How Long Do Fire Extinguishers Typically Last?
Most fire extinguishers are built with an intended lifespan of 5 to 15 years. However, the exact life expectancy of your in-house fire extinguishers depends on several factors.
- Disposable models generally last around 12 years before they expire.
- Rechargeable fire extinguishers have a longer lifespan but must be properly serviced for optimal longevity.
- Every manufacturer should print their product’s expiration date and service recommendations on the extinguisher’s label.
Scheduling regular inspections and checking pressure gauges monthly can help ensure that extinguishers are in working condition and ready for an emergency.
Signs Your Fire Extinguishers May No Longer Be Safe
Regular extinguisher inspections are essential, but you need to know the common signs of wear and malfunction to look for during your assessment.
If you spot any of these warning signs, it may be time to replace your extinguisher — even if it hasn’t technically expired:
- A damaged or missing pin and/or tamper seal
- Low or unsteady readings on the pressure gauge
- Any signs of rust, corrosion, or visible damage on the fire extinguisher’s cylinder
- Leaking fluid or obvious clogs/nozzle obstructions
- Missing or unreadable labels or instruction panels
Whether to Recharge or Replace
Knowing which type of extinguisher you have is crucial when considering whether to recharge or replace it.
- Rechargeable fire extinguishers usually have valves and pressure gauges for durability.
- Disposable models are more likely to have plastic heads — these models can’t be refilled.
Recharging refillable units may be more cost-effective, but replacement is preferred if the extinguisher is damaged or out of date. Remember that recharging must be done by a certified fire equipment professional and shouldn’t be attempted by a layperson.
How to Dispose of Expired Extinguishers Properly
There are a few proper disposal methods for old fire extinguishers, and none involve tossing your expired extinguisher in the trash.
When you need to dispose of an expired extinguisher, contact your local fire department to see if they accept drop-offs. You can also ask local hazardous waste disposal sites about their fire extinguisher guidelines. Fully discharged units may be approved for metal recycling, but checking with your preferred center is essential.
Keep in mind that improperly disposing of an expired fire extinguisher can endanger sanitation workers and those on your team. This is especially true if the canister isn’t fully discharged. Ask your security partner or fire officials how to proceed when in doubt.
Why Regular Fire Safety Inspections Matter
Fire inspections, regulations, and suppression systems exist for one reason: safety. Even the most well-intentioned safety planning can miss a faulty extinguisher or miswired safety panel, so inspections are essential.
- Schedule annual inspections and routine maintenance by professionals.
- Ensure proper placement of extinguishers according to local regulations and/or recommendations from the National Fire Protection Association (NFPA).
- Work with a licensed security and fire protection company like Bates Security to facilitate code compliance and accident readiness.
