Is it Time to Replace Your Fire Extinguisher? Here are 6 Signs


Fire extinguishers are an important safety device that can help to prevent or mitigate damage caused by fires. However, it’s important to understand that they have a limited lifespan and can become less effective over time. Therefore, it’s essential to know the signs that indicate your fire extinguisher needs to be replaced. An expert who specialises in fire extinguisher testing lists the following signs below.


Most fire extinguishers have a lifespan of 5 years, and after that, they should be replaced. If you’re not sure how old your extinguisher is, check the label or tag, which should indicate the date of manufacture or last service. If the extinguisher is more than 5 years old, it must be pressure-tested or replaced if necessary.

Visible Damage

If you notice any visible damage during the fire extinguisher inspection (such as dents, corrosion, cracks, or leaks), it’s time to replace it. Even minor damage can affect the effectiveness of the extinguisher, as well as its ability to hold pressure. A damaged extinguisher may also be more difficult to use in an emergency, which could be dangerous.

Low Pressure

One of the most common signs that a fire extinguisher needs to be replaced is low pressure. This can be caused by a variety of factors, including age, damage, or a leak in the cylinder. If you notice that the gauge on the extinguisher reads below the recommended pressure, it’s time to replace it. Low pressure can indicate that the extinguisher won’t work properly in an emergency, which could be disastrous.

Powder Accumulation

If you have a dry powder extinguisher, you may notice a buildup of powder around the nozzle or discharge area. This can be a sign that the extinguisher has been discharged or leaked, and the powder can make it difficult to use the extinguisher in an emergency. If you notice a buildup of powder, it’s best to replace the extinguisher.


If you notice any discolouration on the extinguisher, such as yellowing or fading, it may indicate that the extinguisher has been exposed to heat or sunlight for an extended period of time. This can affect the integrity of the cylinder, as well as the pressure and effectiveness of the extinguishing agent. If you notice any discoloration during a fire extinguisher inspection near me, it’s best to replace it.

Rust or Corrosion

Rust or corrosion on the exterior of the fire extinguisher can indicate damage to the interior components. Corrosion can weaken the structure of the extinguisher and cause it to fail in an emergency situation. If you notice any signs of rust or corrosion on your fire extinguisher, it’s important to replace it as soon as possible.

Fire extinguishers are an important safety device that should be regularly inspected and maintained. If you notice any of the signs listed above, replace the extinguisher to ensure that it will function properly in an emergency. Always consult with a qualified professional if you need a fire extinguisher test and tag. The experts can also help you pick the right device for your needs, if need be.
