When it comes to ensuring the safety of your business and employees, fire extinguishers are one of the most essential tools in your fire safety toolkit. However, not all fire extinguishers are created equal. Choosing the right type of extinguisher for your specific business needs is critical. Incorrect choices or poor placement can have serious consequences in the event of a fire. This article will guide you through the various types of fire extinguishers, how they work, and how to select the best option for your business, all while ensuring compliance with British standards and guidelines. Understanding The Different Types Of Fire Extinguishers In the UK, fire extinguishers are classified based on the type of fire they are designed to put out. The classification is defined by British Standard BS EN 3-7:2004 for portable fire extinguishers. This standard categorises extinguishers into five main types, each suited to specific fire risks. It is crucial to know the type of fire that could potentially occur in your business premises, so you can make the right choice. 1. Water Fire Extinguishers (Class A) Water fire extinguishers are effective against fires involving solid combustibles such as wood, paper, textiles, and plastics. They should not be used for electrical fires or flammable liquids. Best for: Offices, warehouses, and environments where there are large quantities of paper, wood, or textiles, such as retail stores or educational facilities. 2. Foam Fire Extinguishers (Class A and B) Foam extinguishers are versatile, suitable for Class A and B fires. Class B fires involve flammable liquids such as oils, paints, and petrol. The foam creates a barrier that prevents oxygen from feeding the fire. Best for: Businesses dealing with flammable liquids, such as garages, chemical storage rooms, and areas where fuel is used or stored. 3. CO2 Fire Extinguishers (Class B and Electrical Fires) Carbon dioxide (CO2) extinguishers are highly effective for electrical fires and Class B fires involving flammable liquids. CO2 works by displacing oxygen, suffocating the fire. It also leaves no residue, making it ideal for electrical equipment, computers, and data centres. Best for: Offices, server rooms, IT areas, and businesses with electrical equipment or computer-based operations. 4. Powder Fire Extinguishers (Class A, B, C) Powder extinguishers are suitable for Class A, B, and C fires (involving flammable gases like propane). They are highly effective at smothering the fire but leave a residue that can be harmful to equipment and difficult to clean. Best for: Workshops, garages, warehouses, and industrial facilities where a variety of fire risks may be present, including gas fires. 5. Wet Chemical Fire Extinguishers (Class F) Wet chemical fire extinguishers are specifically designed for Class F fires, which involve cooking oils and fats. These extinguishers release a fine mist of liquid that cools and smothers the fire, preventing re-ignition. Best for: Kitchens and catering businesses, where cooking oils and fats are used, such as restaurants, cafes, and canteens. How To Assess Fire Risks In Your Business Before selecting fire extinguishers, it’s important to assess the risks specific to your business environment. Different workplaces face different fire hazards, and the type of fire extinguisher you choose should correspond to those risks. For instance: - Office Spaces: The primary fire risks are likely to be from electrical equipment, paper, and furniture. A combination of CO2 and water extinguishers is often sufficient.
- Factories or Workshops: These environments may have multiple fire hazards, including the risk of chemical, electrical, and gas fires. A foam, powder, or CO2 extinguisher could be more appropriate.
- Kitchens: In places where cooking oils and fats are used, such as restaurants, a wet chemical extinguisher is a must.
Performing a fire risk assessment, as required by the Regulatory Reform (Fire Safety) Order 2005, will help identify the specific risks in your premises and guide the selection of the right extinguishers. A professional fire risk assessor can help you with this task if needed. The British Standards And Regulations For Fire Extinguishers In the UK, fire extinguishers must conform to British Standards. BS EN 3-7:2004 is the key standard for portable fire extinguishers. This standard covers the construction, performance, and marking of fire extinguishers and ensures that they meet the required levels of safety and performance. In addition, fire extinguishers must be regularly maintained to ensure they remain effective. According to the BS 5306-3:2017 standard, fire extinguishers should undergo annual inspections and maintenance by a qualified professional. Regular maintenance ensures that the extinguishers are charged, accessible, and in good working condition when needed. How To Position Fire Extinguishers In Your Business Once you’ve selected the appropriate fire extinguishers, the next step is ensuring they are placed correctly within your business premises. The Regulatory Reform (Fire Safety) Order 2005 requires that fire extinguishers be clearly visible and easily accessible. Here are some best practices for positioning fire extinguishers: - Accessible and Visible: Extinguishers should be located near potential fire hazards but not too close to them. For example, near kitchens, electrical rooms, or warehouses. Ensure they are visible and clearly marked with appropriate signage.
- At the Right Height: Mount extinguishers at a height that is easy for everyone to access. The handle of a wall-mounted extinguisher should be no higher than 1.5 metres off the ground.
- Clear Signage: Use clear and visible signage indicating the location of extinguishers. Signage should comply with BS 5499, which outlines the design of safety signs for use in the UK.
Training Your Employees Equally important to choosing the right fire extinguishers is ensuring that your staff know how to use them correctly. Fire safety training is essential in helping employees react quickly and confidently in the event of a fire. Staff should be trained in the proper use of fire extinguishers, as well as in the general fire evacuation procedures. The Fire Safety (Employees’ Rights and Duties) Regulations 1999 require that employees receive adequate fire safety training. Regular fire drills should also be conducted to familiarise everyone with evacuation routes and fire safety protocols. Ask The Experts Choosing the right fire extinguisher for your business is crucial to ensuring the safety of your employees and protecting your assets in the event of a fire. By understanding the different types of fire extinguishers, assessing the fire risks specific to your business, and ensuring compliance with British standards such as BS EN 3-7:2004 and BS 5306-3:2017, you can ensure that your fire safety toolkit is up to the task. Remember, fire extinguishers are just one part of your fire safety strategy. Regular maintenance, employee training, and ongoing risk assessments are all equally important in creating a safe environment. Always consult with a professional fire safety expert if you are unsure about your fire safety requirements or need help with risk assessments and compliance.
