Safety Tips: Fire Extinguisher Maintenance and Disposal

A well-maintained fire extinguisher could last for many years. However, most fire extinguishers don’t come with an expiry date and most people often don’t know when the fire extinguisher was first purchased to know how long it has been sat in your building.
We explain what you can look out for when determining when to replace an extinguisher if there is no set expiry date. 

When was the fire extinguisher last serviced?

The first thing to look for is the condition of the fire extinguisher. Then, check the service label to see if it has been serviced at the correct intervals – in most cases this will be annually. Damage, rust and corrosion are indicators that the unit should be replaced.
How old is the fire extinguisher? It can be hard to know exactly when a fire extinguisher was installed in your building, but you can see the manufacturing date of a fire extinguisher date stamped on the body or written on the service label. The manufacture date will determine if the fire extinguisher requires its extended service. 
If your fire extinguisher is either water, powder, or foam, they are due 5 years after first commissioning. If you have a CO2 extinguisher this will be due after 10 years. 

Is the fire extinguisher outdated?

Some fire extinguishers may have been forgotten about especially in older buildings. Since fire extinguishers have evolved over the years, some older ones may not meet current standards. Fire extinguisher that can no longer be serviced according to the manufacturers’ specification or where parts are no longer available should be replaced. 
Many extinguishers are no longer economical to test and recharge at the 5-year Extended Service intervals, so you may well be offered a new one instead.
If you are concerned about any fire extinguishers in your building, you can contact RCL Safety Centre for expert advice. We offer you advice and guidance on fire safety in your premises. 
There are certain problems you should address promptly: –
•    The handle is broken
•    The pressure gauge needle is in the red zone
•    The maintenance record isn’t up to date
•    The nozzle has become blocked
•    The headcap locking pin is missing or the security seal is broken

When Fire Extinguishers Expire

Fire extinguishers are often only “good” for a certain amount of time. While they may not have a set expiration date, they do need to be tested periodically to ensure that the contents are still functioning properly and the cannister itself isn’t damaged.

There are essentially two types of fire extinguishers: rechargeable and disposable. You can check which kind you have by checking the gauge. Rechargeable ones will read either “charge” or in the green, “overcharge” or “recharge,” and disposable ones will read “full” or “empty.”

If you have a disposable extinguisher, they’re just that – disposable; they cannot be recharged. Extinguishers are filled with a pressurized gas – typically nitrogen or carbon dioxide – that over time can lose pressure and become unusable. Or, if used, the chemical will of course no longer be inside of the unit. If you have this type of extinguisher, you’ll need to replace it after use or once the chemicals have become ineffective and depressurized – typically at least every 12 years.

Rechargeable fire extinguishers are a little bit different. These also contain pressurized chemicals, but the cannister is designed to be “recharged” or “refilled.” They need to be recharged after every use – even if not all of the contents were used – and also every six years even without use, according to the National Fire Prevention Association (NFPA).

Recharging works by completely depressurizing the extinguisher, cleaning all of the parts thoroughly, installing a new valve, refilling with the active agent and re-pressurizing the unit. A trained professional should recharge any extinguishers.

What to Do with Expired Extinguishers

Your fire extinguisher is expired or damaged – now what?

If it simply needs to be recharged, then you should contact a professional fire and life safety company like RCL Safety Centre to recharge it and conduct an inspection to ensure it’s good to go.

If the extinguisher is disposable or damaged, then properly disposing of the unit is critical. Fire extinguishers with any contents remaining inside should never be thrown in the trash, as they contain hazardous, pressurized chemicals. Instead, fire extinguishers should be taken to your local hazardous waste location or a local fire department. If you’re taking one to the fire department, call ahead to ensure that they receive expired extinguishers.

Not only is improper disposal of fire extinguishers bad for the environment and dangerous – there can also be a fine depending on where you live. Be sure to utilize one of the other options instead.

If your fire extinguisher is completely empty of any chemicals, then it may be able to be thrown away in your normal trash. You should test the unit by releasing the pressure in an open area and letting it sit out in an open area for several days, to make certain all of the pressure is released. When in doubt, ask your local fire department or trash company about disposal.
