Optimising your fire safety equipment such as extinguishers ensures they are reliable and functional, ready to be used in a time of need. Ignoring maintenance can have catastrophic consequences, significantly increasing the potential damage and risk to life in the event of a fire.

The Role of Fire Extinguishers in Safety

It is important to understand the vital role these devices play in ensuring safety. Fire extinguishers are designed to suppress or extinguish small fires, preventing them from spreading and causing further damage. They are an essential tool to buy time, allowing individuals to escape a building or to control smaller fires before emergency services arrive.

Without fire extinguishers or with faulty ones, the ability to respond effectively when a fire breaks out is severely compromised. Regular monthly visual inspections and an annual fire extinguisher service are essential to ensure that these devices are ready and able to fulfil their role in protecting lives and property.

Legal Requirements for Fire Extinguisher Maintenance

Fire safety in the UK is governed by legislation to minimise the risks and ensure proper fire prevention measures are in place. The Regulatory Reform Fire Safety Order 2005 outlines the legal requirements for fire safety, including extinguisher maintenance.

Under this order, it is the responsibility of the “Responsible Person” to ensure that extinguishers are properly maintained and regularly checked. Failure by a competent person to comply with this legal requirement can result in severe penalties and, more importantly, put lives at risk.


Firstly, the accessibility of extinguishers is of utmost importance. Extinguishers should be easily visible and within reach, ensuring that they can be quickly accessed in case of an emergency. This means that they should not be obstructed by furniture, equipment, or any other objects. This ensures they are correctly located.


They also need to be fully charged to be effective. A fully charged extinguisher contains the necessary amount of extinguishing agent to combat a fire. Regular checks should be conducted to ensure that the pressure gauge on the extinguisher indicates that it is fully charged. If the pressure gauge shows a lower reading, it may indicate it needs to be recharged.

Free from Defect

Extinguishers should be free from any defects that may hinder their functionality. This includes checking for visible signs of damage, such as dents, corrosion, or leakage. Any damaged extinguishers should be immediately replaced or repaired to ensure their effectiveness in case of a fire.

It is also important to note that different types of extinguishers are designed to combat specific types of fires. For example, water-based extinguishers are suitable for fires involving ordinary combustible materials, while CO2 extinguishers are effective for electrical fires. Checks should include verifying that the correct type of extinguisher is in place for the specific hazards present in the building.

Regular Checks

Regular checks should be carried out by responsible person or individuals who are knowledgeable about the different types of extinguishers and their maintenance requirements. These checks should be documented, including the date of the check, the name of the responsible person for conducting the check, and any actions taken, such as recharging or replacing extinguishers.

Extinguisher visual inspections are essential for ensuring the safety of occupants, employees, and visitors. By conducting visual inspections, extinguishers can be maintained in optimal condition, ready to be used in case of a fire. Compliance with legal requirements and proper maintenance practices can significantly reduce the risks associated with fires and protect lives and property.

Types of Fire Extinguishers and Their Specific Checks

There are several types of fire extinguishers, each designed to tackle different types of fires. It is essential to understand the specific checks required for each type to ensure their effectiveness. Let’s explore some of the most common types of fire extinguishers and their maintenance requirements:

Water Extinguishers

Are suitable for fighting fires involving solid combustibles, such as paper, wood, and fabric. Regular checks for water extinguishers include ensuring the extinguisher is full and has not been discharged or tampered with. The pressure gauge should be within the recommended range, indicating that the internal pressure is sufficient for effective use.

Additionally, it is important to inspect the condition of the hose and nozzle. Any signs of wear or damage to service parts should be addressed promptly to ensure proper functionality. The handle and safety pin should also be checked to ensure they are intact and easily accessible in case of an emergency.

Water extinguishers should be stored in a designated place in a location that is easily accessible and visible. It is crucial to keep them away from potential obstructions or clutter that may hinder their quick retrieval during a fire incident.

CO2 Extinguishers

CO2 extinguishers are primarily used to tackle fires involving flammable liquids and electrical equipment. Checks for CO2 extinguishers involve examining the discharge horn and checking for any obstructions or damage. The weight of the extinguisher should also be within the specified range, indicating that it is full and ready for use.

In addition to these checks, it is vital to visually inspect the condition of the pressure gauge and ensure it is functioning correctly. The CO2 extinguisher should be stored in a cool and dry place, away from direct sunlight or extreme temperatures, to prevent any potential damage or decrease in effectiveness.

Moreover, it is recommended to have a trained professional conduct periodic inspections annual servicing and maintenance on CO2 extinguishers to ensure their optimal performance. They can assess the overall condition of the extinguisher, including the integrity of the cylinder and the functionality of the valve.

Foam Extinguishers

Foam extinguishers are effective for fires involving flammable liquids, such as petrol, oil, and paints. Maintenance checks for foam extinguishers include ensuring the pressure gauge is within the recommended range and inspecting the discharge nozzle, ensuring it is clear of any obstructions.

It is important to check the foam concentrate level and ensure it is at the correct pressure range and appropriate level for effective firefighting. The foam extinguisher should be stored upright to prevent the foam from settling or separating, which may affect its performance during an emergency.

Additionally, foam extinguishers should be visually inspected for any signs of corrosion or damage to the cylinder. If any issues are detected during visual inspections, it is important to have the extinguisher serviced or replaced by a qualified professional to ensure its reliability.

Regular training and education on the proper use of foam extinguishers should also be provided to individuals who may need to operate them in an emergency. This will ensure that they are familiar with the operational and safety limits of the equipment and can effectively respond to a fire incident.

The Fire Extinguisher Inspection Process

Proper inspection of fire extinguishers involves a systematic process to verify their condition. This process typically comprises the following steps:

Initial Visual Inspection

The initial visual inspection involves assessing the overall condition and accessibility of the fire extinguisher. This includes checking for any physical damage, ensuring the extinguisher is mounted and correctly located, and ensuring the operating instructions and safety pin are in place.

Detailed Extinguisher Check

During the detailed extinguisher check, each extinguisher is individually inspected to ensure it meets the necessary requirements. This includes examining the pressure gauge, checking the weight, inspecting the extinguisher label for any signs of deterioration, and confirming the presence of a valid inspection tag.

Documentation and Reporting

Documentation is a crucial part of extinguisher checks, providing a record of maintenance activities. After each inspection, it is important to update the inspection log or tag with the date, name of the inspector, and any actions taken. This documentation serves as evidence of compliance with legal requirements and can be used to track the history of each fire extinguisher.

Frequency of Extinguisher Checks

Regular fire extinguisher checks are crucial to ensure their reliability in case of fire. There are two main categories of checks to be performed:

Regular Self-Inspections

Self-inspections should be conducted regularly by the responsible person or any designated competent person within the organisation. These checks typically involve a visual examination of the fire extinguishers. This ensures they are undamaged, accessible, and have not been tampered with. The frequency of self-inspections depends on various factors:

  • The type of extinguisher
