Fire Extinguisher Testing – A Critical Aspect of Fire Safety in London

Ensuring the safety and preparedness of any residential or commercial space in London involves a series of crucial steps, among which fire extinguisher testing stands paramount. 

At Metro PAT, we understand the importance of regular and thorough testing, a process often confused with, but distinctly different from, general servicing.

Understanding the Need for Fire Extinguisher Testing


Fire extinguishers are your first line of defence against a fire outbreak. But how sure are you that they will work when needed? That's where testing comes in. Unlike servicing, which involves physical checks and maintenance tasks to ensure the unit is operational, testing focuses on verifying that the extinguisher will perform effectively in an emergency.


The Regulations Guiding Fire Extinguisher Testing in London


The Regulatory Reform (Fire Safety) Order 2005 mandates that all firefighting equipment in the UK must be in good working order. For London businesses and property owners, this translates to adhering to British Standard BS 5306-3:2017, which specifies the procedures for the commissioning and maintaining of portable fire extinguishers.


Types of UK Fire Extinguishers: Classes and Uses


When it comes to fire extinguisher testing, it's essential to recognise that different types of extinguishers are designed for various classes of fires. Below is a table outlining the main types of fire extinguishers available in the UK, their corresponding fire classes, and their recommended uses.

Type of Extinguisher

Fire Class

Fire Extinguisher Testing Process Demystified


Metro PAT is dedicated to providing thorough and professional testing of fire extinguishers to ensure they are reliable in the event of a fire. Here's a closer look at our comprehensive testing process:


Visual Inspections


The first step in our testing process involves a meticulous visual examination of each fire extinguisher. Our expert technicians look for the following:


  • Signs of wear and tear, such as dents or rust.

  • Obstructions in the hose or nozzle that could impede discharge.

  • Legibility of operating instructions.

  • Validity of the maintenance tag, indicating the last service date.

  • Security of the tamper seal and safety pin.


Any discrepancies found during this inspection may necessitate further servicing or replacement of the unit.


Weight and Pressure Checks


Each type of fire extinguisher has a specified weight and pressure required for optimal operation. Our checks include:


  • Weighing the extinguisher to ensure it meets the expected weight indicates no leakage has occurred.

  • Checking the pressure gauge or indicator to ensure the unit is within the operable range.

  • Assessing the integrity of the valve and shell for signs indicating depressurization.


Additional steps, such as recharging or hydrostatic testing, may be required if the extinguisher fails to meet its required specifications.


Discharge Testing


Also referred to as extended servicing, discharge testing is carried out at specified intervals according to British Standards. During this process:


  • The extinguisher is fully discharged in a controlled environment to confirm it operates correctly.

  • The internal condition of the cylinder is inspected for corrosion or any other irregularities.

  • After successful discharge and inspection, the extinguisher is refilled with the appropriate agent and re-pressurized.


This test is critical as it simulates real-world use conditions to ensure functionality.


Record Keeping


Proper documentation is an integral part of the testing process. Metro PAT maintains detailed records that include:


  • The date of the test and the technician who conducted it.

  • Any issues found during the testing process and the actions taken to correct them.

  • The next due date for testing or servicing.

  • A log of replacement parts or refilling materials used.


This meticulous record keeping ensures that all fire extinguishers are tracked for their lifespan and maintains compliance with legal requirements.


By adhering to these stringent testing procedures, Metro PAT ensures that every fire extinguisher we test is ready to perform when needed, providing peace of mind and safety for our clients throughout London.

Understanding Fire Extinguisher Testing Standards


Overview of British Standards


To ensure the safety and efficacy of fire extinguishers, it's imperative to adhere to the British Standards, which provide the framework for fire extinguisher maintenance and testing. These standards are not merely guidelines; they are authoritative protocols meticulously developed to guarantee that fire extinguishers function as intended in an emergency.


BS 5306-3:2017 – Commissioning and Maintenance of Portable Fire Extinguishers:


This particular standard is the cornerstone of fire extinguisher maintenance. BS 5306-3:2017 outlines the recommendations for the commissioning (the process of bringing an extinguisher into service) and the periodic maintenance of portable fire extinguishers. It provides detailed procedures for inspecting extinguishers, diagnosing any issues they may have, and performing necessary repairs or replacements.


The standard specifies that:


  • Extinguishers should be initially commissioned on-site by a competent person to ensure they are fit for purpose.

  • The user should perform regular visual inspections to monitor for any signs of tampering or damage.

  • Essential services should be carried out annually by a competent person to ensure the extinguishers are in good working order.

  • An extended service, which includes a full discharge and refill, should be conducted at intervals specified by the manufacturer, usually every five years for water, foam, powder, and wet chemical extinguishers and every ten years for CO2 extinguishers.


BS 5306-8:2012 – Selection and Positioning of Portable Fire Extinguishers: While BS 5306-3:2017 focuses on maintenance, BS 5306-8:2012 provides guidelines on choosing the correct type and number of extinguishers for a given environment. It also advises on their proper placement to ensure accessibility during a fire.


BS 5306-9:2015 – Recharging and Hydrostatic Pressure Testing: This standard covers specifics on how to recharge extinguishers properly after use or as part of the extended servicing, as well as the requirements for hydrostatic pressure testing, which is a method used to test the integrity of the extinguisher's cylinder.


By strictly following these standards, Metro PAT ensures that every fire extinguisher is tested precisely and is up-to-date with current fire safety expectations. Our commitment to maintaining these standards is one aspect of our dedication to providing exemplary fire safety services across London.

Frequently Asked Questions About Fire Extinguisher Testing London


Common Concerns Addressed


Below are some of the most frequently asked questions about fire extinguisher testing and comprehensive answers.


How often should fire extinguishers be tested? Fire extinguishers should receive a basic service from a competent person once a year as per BS 5306-3:2017. Extended servicing, which includes a discharge test and refill, should be done every five years for most extinguishers, except for CO2 extinguishers, which require this service every ten years.


How long does the testing process take per extinguisher? A basic annual inspection typically takes around 15 to 20 minutes per extinguisher. This includes a thorough visual inspection, pressure check, and any minor maintenance required. Extended servicing will take longer as it involves discharging, recharging, and re-pressurizing the extinguisher.


What happens if an extinguisher fails a test? An extinguisher must be repaired or replaced immediately if it fails its test. Metro PAT technicians will advise on the best course of action depending on the type and extent of the damage or malfunction. Faulty extinguishers are tagged out of service and should not be used until they are repaired or replaced and retested.


Can an extinguisher still fail even if it hasn't been used? Yes, fire extinguishers can fail due to internal corrosion, seal degradation, or pressure loss, even if not used. Regular testing ensures these issues are identified and corrected so the extinguisher is operational when needed.


Is there a difference between testing and servicing? Yes. Testing may involve visual inspection and functional checks to ensure the device operates correctly.
