Fire Extinguisher Life Expectancy & Maintenance

The average lifespan of an extinguisher varies according to its category:

Water fire extinguishers have an average lifespan of 10 years. However, it should be serviced every year to check its condition and should be recharged every 5 years.

The powder extinguisher has an average lifespan of 20 years, which is the longest lifespan compared with other extinguishers. However, it is still important to service this extinguisher annually and recharge it every 5 or 10 years, depending on the model.

CO2 extinguishers have a lifespan of 10 years and must be inspected every year with a refill every 10 years.

Foam extinguishers have an average lifespan of 15 years and should be checked every year. Recharging should be done every 5 or 10 years like the powder extinguisher.

Please be aware, these lifespans are for guidance only, they may vary depending on the model and also the environment in which it is found. It is therefore important to check with the manufacturer.

To ensure that fire extinguishers remain in good working order and are ready for use in an emergency, they must be inspected and maintained at regular intervals.

In the UK, the maintenance of portable fire extinguishers is covered by BS 5306-3:2017 – Commissioning and Maintenance of Portable Fire Extinguishers. The standard recommends that all fire extinguishers are subject to an annual service by a competent person, with more extensive maintenance or replacement carried out at specified intervals depending on the type of extinguisher.

Following the recommended inspection and maintenance schedule helps organisations minimise risk, remain compliant with their fire safety responsibilities and ensure that extinguishers will operate effectively when needed.

At Scutum, we recommend entering into a fire extinguisher maintenance agreement with a competent specialist provider. This ensures that your fire extinguishers are inspected and serviced at the appropriate intervals, helping you maintain compliance and reducing the administrative burden of managing inspection schedules and maintenance visits internally.

Regular fire extinguisher maintenance is essential to ensure that equipment remains safe, compliant and ready to operate in an emergency. A poorly maintained extinguisher may fail when it is needed most, potentially putting lives, property and business operations at risk.

Effective maintenance helps to ensure:

• Regulatory compliance: Regular servicing in accordance with relevant UK standards, such as BS 5306-3, helps organisations meet their fire safety obligations and demonstrate that appropriate fire protection measures are in place. Failure to maintain fire safety equipment could lead to enforcement action, increased insurance costs or, in serious cases, business disruption or prosecution.
• The safety of people and property: Properly maintained fire extinguishers can play a vital role in controlling a small fire before it escalates, helping to protect employees, visitors and premises.
• Business continuity: A fire can have significant financial and operational consequences, including damage to buildings, loss of stock, interruption to services and reputational harm. Regular maintenance helps ensure that extinguishers will operate effectively, supporting a swift response and reducing the potential impact of an incident.

Investing in regular fire extinguisher maintenance is therefore not only a legal and practical requirement, but also an important part of protecting your people, assets and long-term business resilience.

The maintenance of an extinguisher is carried out in several stages:

Visual inspection:A check is made of the general condition of the extinguisher as well as its accessibility.

Technical assessment:The checking agent ensures that the extinguisher shows no signs of leakage and checks the pressure of the extinguisher.

Recharging by the agent: Depending on the maintenance cycle, the agent may have to recharge the extinguisher.

Adding a maintenance label to the extinguisher: This label is proof of the equipment's compliance. It also indicates the actions carried out on it.

While it is not a legal requirement to have a fire extinguisher maintenance contract in place, it is highly advisable to engage a competent fire extinguisher maintenance provider to ensure that your equipment is inspected and serviced at the appropriate intervals.

Regular fire extinguisher maintenance is an important part of meeting your fire safety responsibilities and helping to protect people, property and business operations. By following the recommended maintenance schedule, organisations can reduce the risk of equipment failure and ensure that extinguishers will operate effectively in an emergency.

Although a maintenance contract is not compulsory, partnering with a specialist provider can provide valuable peace of mind, ensuring that inspections and servicing are carried out on time and by competent professionals.
