Fire Extinguisher Lifespan: Key Safety Tips for Maintenance

Fire extinguishers are a common sight in workplaces and homes, providing a first line of defense against small, controllable fires and can prevent serious damage or injury when used correctly. However, extinguishers are only effective if they are in good working order.

Here, the team at health and safety training experts High Speed Training explains how long fire extinguishers last and highlights key safety points that you need to know about.

Dr. Richard Anderson, Director of Learning at High Speed Training, said: “Most standard, portable fire extinguishers last between 5 and 15 years, depending on the type of fire extinguisher, the environment it’s kept in, and the maintenance schedule.

“An expired or poorly maintained extinguisher can be dangerous. It may fail to discharge, leak, or even rupture under pressure. Over time, components can degrade, pressure can be lost, and the extinguishing agent may become less effective.

“Relying on a faulty fire extinguisher during an emergency can put lives at risk and may leave your organization non-compliant with fire safety regulations, such as the Regulatory Reform (Fire Safety) Order 2005.”

In the UK, fire extinguisher maintenance is guided by BS 5306 standards. These recommend annual servicing by a competent person, with extended servicing at 5-year intervals for certain types of extinguishers. They also recommend hydraulic pressure testing every 10 years for refillable extinguishers.

You can usually find the date when the fire extinguisher was manufactured stamped on the body of the extinguisher or printed on the label. This helps determine its age and when servicing or replacement may be required.

In some cases, the date can be hard to see due to wear, paint, or dirt. Try viewing the surface in better lighting or gently cleaning the area where the stamp may be located to make it more visible.

When to Replace a Fire Extinguisher

Regular checks are essential to ensure fire extinguishers remain safe and effective. Signs that an extinguisher may need servicing or replacing include

• Visible damage, such as dents, cracks or corrosion.
• Signs of leakage or residue around the nozzle or valve.
• Faded, torn or missing labels that make instructions unreadable.
• A missing or broken safety pin or tamper seal.
• The pressure gauge needle in the red zone.
• Damaged, blocked or perished hoses.
• Evidence of unauthorised use or partial discharge.

Dr Anderson said: “If a fire extinguisher has expired or is no longer in safe working condition, it must be disposed of correctly. Fire extinguishers are pressurised vessels and may contain chemicals that require controlled handling. Proper disposal of fire extinguishers helps to protect the environment, ensures legal compliance and prevents unsafe equipment from being reused.”

“Do not place fire extinguishers in general waste or recycling bins. It is best to contact a licensed waste disposal contractor or your extinguisher service provider, or check whether the manufacturer offers a take-back or recycling scheme. Ensure the unit is fully depressurised by a qualified professional before disposal, and keep disposal records where required for workplace compliance.
