Guide to Annual Fire Extinguisher Servicing

Annual fire extinguisher servicing is a critical part of workplace fire safety in the UK. It must be carried out by a competent person or a qualified fire extinguisher technician, ensuring all fire suppression equipment—whether water, foam, powder, or CO2 extinguishers—functions correctly when needed. Regular professional servicing ensures compliance with UK fire safety legislation, specifically the Regulatory Reform (Fire Safety) Order 2005 (RRO), and follows the requirements of British Standard BS 5306-3. This not only protects your business from escalating fire risks but also from legal penalties.

TL;DR: Annual fire extinguisher servicing must be performed by a competent person/qualified technician. Monthly visual checks by staff are helpful but do not replace the mandatory annual service for any extinguisher type.

Key Takeaways:

  • Annual servicing must be conducted by a competent person or qualified fire extinguisher technician.
  • UK fire safety law (e.g., the Regulatory Reform (Fire Safety) Order 2005) and British Standard BS 5306-3 require documented annual servicing.
  • Monthly visual checks by staff are recommended but do not substitute for professional annual servicing for portable fire extinguishers.
  • Professional technicians inspect mechanical components and perform maintenance beyond basic visual checks on the fire extinguisher.
  • Non-compliance can result in substantial fines or prosecution.

Understanding Your Legal Obligations for Fire Extinguisher Servicing

As a 'Responsible Person' under the RRO 2005, business owners or designated individuals are legally required to ensure fire safety equipment, including portable fire extinguishers, is maintained in efficient working order. This typically means annual servicing by a competent person, as defined by BS 5306-3.

Documentation is essential: maintain records of all servicing and maintenance. Each extinguisher must have a service label with the date and technician’s details. Poor record-keeping or neglect can lead to enforcement action by the Fire and Rescue Service.

Who Should Perform Annual Fire Extinguisher Servicing?

Annual servicing MUST be performed by a competent person. This is typically a fire extinguisher technician who is trained and certified by organisations such as BAFE (British Approvals for Fire Equipment) or the FIA (Fire Industry Association), and who works in accordance with BS 5306-3 standards. Regular employees cannot perform this official annual service unless specifically trained and certified as competent.

Fire extinguishers require technical expertise for proper maintenance. Professionals are trained to spot issues missed by untrained eyes and carry out necessary maintenance procedures. Properly maintained fire extinguishers can prevent many small fires from becoming major incidents. Professional maintenance is about effective fire prevention and protection, ensuring your fire extinguishers work when needed.

What Technicians Check During Servicing

Competent technicians conduct a comprehensive examination in accordance with BS 5306-3. Professional servicing includes verifying extinguishers are:

  • Correctly located and mounted (as per BS 5306-8).
  • Easily accessible, with no obstructions, and have clear operating instructions.
  • Inspected for corrosion, damage, or tampering.
  • Showing correct pressure (for stored pressure types). (Vital for all types of fire extinguishers, including CO2 fire extinguishers, powder fire extinguishers, and water extinguishers).
  • Correctly weighed (for CO2 and cartridge-operated extinguishers).
  • Have discharge hoses and nozzles clear and undamaged.
  • Confirming service dates and recommending extended service, overhaul, or replacement as needed based on the extinguisher type and condition.

Technicians will assess external condition and internal components as required by the service schedule.

Monthly Visual Inspections: Your Team's Responsibility

Implement regular monthly visual checks by trained employees as part of your fire safety routine. These supplement the annual professional service and are good practice under the RRO.

Train your team to check for:

  • Obvious physical damage (dents, rust, leaks).
  • Correct pressure gauge readings (if fitted).
  • Clear, unobstructed access.
  • Intact seals and safety pins.
  • Visible and legible instructions and unobstructed nozzles.

Document these checks, for instance, in a fire logbook. They don't replace the required annual professional servicing but enhance day-to-day fire safety. Combining monthly checks and annual servicing as part of their fire risk assessments creates a robust fire safety management system.

Beyond Annual Servicing: Extended Service and Overhaul/Testing

Annual servicing is part of a comprehensive maintenance schedule. British Standard BS 5306-3 also specifies requirements for more detailed servicing at longer intervals:

Extended Service: This is required for most water, foam, powder, and wet chemical extinguishers, typically every 5 years. It involves a more thorough examination than the basic annual service, including a test discharge, internal inspection, and replacement of certain components. Some primary sealed powder extinguishers may have different requirements.

Overhaul and Testing (for CO2 extinguishers): CO2 fire extinguishers require an overhaul and hydraulic pressure test every 10 years to ensure the integrity of the cylinder. After this, they are typically refurbished or replaced.

These specialised services must be carried out by competent technicians with the appropriate equipment and knowledge.

Minimum Number of Extinguishers

UK regulations and BS 5306-8 recommend that for any storey, the number of Class A extinguishers should be such that the aggregate A rating is not less than 0.065 x floor area of the storey in m2, with a minimum of 2 extinguishers per floor with an aggregate A rating of at least 26A. For very small premises where this might hinder escape, a specific fire risk assessment should determine appropriate provision.

Finding a Qualified Fire Protection Company

Selecting the right fire protection company is a crucial decision. Look for reputable providers, ideally those with third-party accreditation (e.g., BAFE SP101 scheme), whose technicians are trained and competent to work in accordance with BS 5306. Request references. Many companies offer servicing for a full range of fire extinguishers and other fire safety equipment like fire blankets or fixed fire extinguishing systems. Consider companies offering fire extinguisher stands or cabinets if needed. You can often buy fire extinguishers online or through specialist suppliers in the fire industry. Ensure they provide high quality fire safety equipment compliant with British Standards.

The right partner not only performs servicing but can also provide valuable fire training on using different fire extinguisher types (knowing which extinguisher should be used for different classes of fire).

Coordinating Servicing for Maximum Efficiency

Schedule annual fire extinguisher servicing alongside other fire safety system checks (like fire alarms or emergency lighting) to minimise disruption and potentially lower costs. Use calendar reminders or opt for service contracts which often include automatic scheduling. Factor in requirements for various extinguisher types (e.g., wet chemical fire extinguishers in kitchens, CO2 fire extinguishers near electrical equipment).

Documentation Best Practices

Maintain both digital and physical records of all servicing and maintenance, including your fire logbook, as required by the Regulatory Reform (Fire Safety) Order 2005. Organise by date and extinguisher location/ID. Ensure service labels are attached to extinguishers and are legible. Make records readily accessible for inspection by the Fire and Rescue Service or other relevant authorities. Thorough documentation demonstrates your commitment to fire safety and legal compliance.
