Getting a fire extinguisher isn’t the end of the story. Like most things in life, fire extinguishers have a finite lifespan, with a whole host of factors influencing how long they last. Simple things like the type of extinguisher and how much damage it’s been subjected to means there is no one answer.

However, the guidance here in the UK is that most extinguishers should be replaced or be given an extended service every five years. This changes for CO2 extinguishers, which should be replaced at least every 10 years, while no fire extinguishers should exceed 20 years in age, even if undamaged and unused.

All of these recommendations are designed to help keep fire extinguishers fully functional for when you need them most. So, how do you know how long yours should last? Here are some things to keep in mind and investigate for yourself.

How to find the expiration date on a fire extinguisher

Maybe you’ve inherited a business with fire extinguishers and don’t know how old they are. If that’s the case, you can locate the expiration date on the unit itself to see when it was made. 

This date should be printed or etched into the body of the extinguisher, but it could be in a variety of places, so be sure to check:

• The top of the cylinder
• The bottom of the cylinder
• The neck and the nozzle
• The printed label

In some cases, it may be difficult to see the date as the surface may have worn or been painted. Try moving the extinguisher in different lighting to get a better look or gently rub away any paint or dirt where you think the date may be hiding.

How fire extinguishers can be recharged

Some fire extinguisher types can be recharged or refilled as part of their extended service and testing to extend their life. This is useful if the unit has been used or has gradually lost pressure over time. Water, foam, powder and CO2 extinguishers are the types you can commonly refill.

The impact of damage and wear on fire extinguishers

Any damage to your fire extinguisher will likely mean it needs to be serviced or replaced sooner. This is because you need to be absolutely sure it will work when required in an emergency. Keep an eye on your extinguishers for the following types of damage and wear:

• Torn hoses or nozzles
• Broken or missing pins and tamper seals
• Dents and scratches
• Worn instructions
• Corrosion and leaks

How to keep your fire extinguisher working for longer

Regular inspections are vital to help keep your extinguishers in good condition. Be sure to carry out your own monthly checks, and book appointments for professional maintenance.

Annual service checks from a competent professional should help you to keep on top of things, reducing risk and, ultimately, helping to save lives and protect your assets should the worst happen. 

Proper training and education on fire extinguisher use for staff, visitors or anyone who uses your building will also help to prolong the life of your units. A greater understanding of how they work and the risks of misuse will ensure your fire extinguishers are respected and preserved.
