Typical Lifespan of Fire Extinguishers

Most fire extinguishers are designed to last between 5 and 15 years, depending on the type and manufacturer. This isn’t just a random number; it’s based on how the chemicals inside the extinguisher degrade over time. Even if your extinguisher looks fine on the outside, the contents can become less effective as they age.

I remember a client named Tom who called me up in a panic because his fire extinguisher wouldn’t work during a minor kitchen fire. When we inspected it, we found that it was over 15 years old. It was a tough lesson on why expiration dates matter.

Why Expiration Matters

Think of your fire extinguisher like a litre of milk. Over time, the milk goes off, no matter how tightly sealed it is. The same happens with fire extinguishers. They’re filled with pressurised chemicals that, over time, can lose their effectiveness. An expired extinguisher might not have enough pressure to put out a fire, and that’s a risk no one should take.

How to Check if Your Fire Extinguisher is Expired

Locate the Expiration Date

The first step is to locate the expiration date. Most fire extinguishers have a label on the side or bottom where you’ll find this information. If it’s not immediately visible, look for a date stamp or a label that indicates when it was last serviced. If you’re having trouble finding it, you might need to consult the manufacturer’s website or your original purchase documentation.

Pro Tip: Some extinguishers don’t have a clear expiration date but include a manufacture date. In these cases, use the general rule of thumb to replace the extinguisher after 10-15 years.

Visual Inspection

Next, do a visual inspection of the extinguisher. Check for any signs of damage like rust, dents, or corrosion. If you see any of these, it’s a red flag that the extinguisher might not be reliable.

Maintenance Tags and Service Records

If your extinguisher has a maintenance tag or service record, check the last inspection date. Some extinguishers are professionally serviced every few years, and these tags provide a handy reference. If the tag shows the extinguisher hasn’t been serviced recently, it might be time for a replacement or servicing.

What to Do If Your Fire Extinguisher is Expired?

Immediate Actions

Replace It: If your extinguisher is expired or shows signs of damage, replace it as soon as possible. 

Dispose of It Properly:  Don’t just toss an expired extinguisher in the trash. Many fire departments and local waste management services offer proper disposal services. Some manufacturers also provide recycling programs. Proper disposal is crucial to avoid accidents and environmental harm.

Choosing a New Fire Extinguisher

Type of Extinguisher: Choose the right type for your specific needs. Here’s a quick rundown:

• Class A: For ordinary combustibles like wood and paper.
• Class B: For flammable liquids like petrol and oil.
• Class C: For electrical fires.
• Class D: For combustible metals.
• Class K: For kitchen fires involving cooking oils and fats.

Regular Maintenance Tips

Routine Inspections

Perform a quick visual check of your fire extinguisher every month. Make sure it’s in its designated place, the pressure gauge is in the green, and there are no signs of damage. A monthly check is a small investment of time for your safety.

Pro Tip: Set a calendar reminder or use a checklist to keep track of these inspections.

Keeping Records

Maintain a log of your inspections and any service or replacement activities. This helps you keep track of when you last checked or serviced your extinguisher and ensures you stay on top of maintenance.

Professional Servicing

Schedule professional servicing if required. Many companies offer annual inspections and recharging services. Professional servicing ensures that your extinguisher is in top shape and ready to go in case of an emergency.

What Should I Do if My Fire Extinguisher Doesn’t Have an Expiration Date?

If you can’t find an expiration date, refer to the manufacturer’s guidelines. If you can’t locate any information, it’s generally a good idea to replace the extinguisher.

How Can I Tell if My Fire Extinguisher is Still Effective Even if It Hasn’t Expired?

Even if your extinguisher isn’t expired, check for physical damage, ensure the pressure gauge is in the green, and verify that it has been serviced recently. If in doubt, consider having it inspected by a professional.

Can I Refill an Expired Fire Extinguisher Myself?

It’s not advisable to refill an expired fire extinguisher yourself. This should be done by a certified professional to ensure it’s properly recharged and safe to use.

Checking and replacing your fire extinguisher might seem like a small task, but it’s a crucial part of fire safety. By ensuring your extinguisher is within its operational lifespan and in good condition, you’re taking a vital step to protect your home, family, or business from fire hazards.
