All Fire Extinguishers

Fire extinguishers are essential safety devices that can mean the difference between a minor incident and a devastating blaze. But with different fire extinguishers designed for specific fire classes, choosing the proper extinguisher for your property isn't always straightforward. Understanding the various types available will help you make informed decisions about fire safety.

The main types of fire extinguishers

There are five primary types of fire extinguishers, each designed to effectively tackle specific fire classes. Water extinguishers are most effective on Class A fires, which involve ordinary combustibles such as wood and paper. Foam extinguishers handle Class A fires, although not all of them are suitable for Class B fires. Dry powder extinguishers offer the broadest coverage, ideal for Class A, B, and C fires. Carbon dioxide (CO2) extinguishers excel in extinguishing electrical fires and flammable liquids, leaving no residue. Wet chemical extinguishers are engineered explicitly for Class F fires involving cooking oils and fats.

Choosing the right fire extinguisher type

Selecting the appropriate extinguisher depends on your specific fire risks. Consider what materials are present in your environment. Offices typically need water, water mist or foam extinguishers for paper and electrical equipment. Kitchens require wet chemical extinguishers for cooking fires. Garages and workshops benefit from dry powder extinguishers due to the presence of flammable liquids and electrical equipment. Industrial settings often need multiple types to cover various hazards.

Are there fire extinguishers that work on multiple fire classes?

Yes, several types of extinguishers can handle multiple fire classes. Dry powder extinguishers are remarkably versatile and practical on Class A, B, and C fires. This makes them popular for vehicles and mixed-risk environments. Some foam extinguishers are not suitable for class B fires and almost all are dielectrically tested and so are suitable for use on fires involving electrical equipment. However, specialist extinguishers, such as wet chemical for cooking fires and CO2 for electrical equipment, often provide better-targeted protection.

The difference between portable and wheeled fire extinguishers

Portable extinguishers are designed for handheld use, typically ranging from 1kg to 9kg. They're perfect for immediate response to small fires. Wheeled extinguishers are larger units, typically ranging from 25kg to 50kg, and are mounted on wheels for enhanced mobility. These provide greater fire-fighting capacity and longer discharge times, making them ideal for industrial premises, car parks, and areas with higher fire loads.

Do different fire extinguishers require different maintenance?

All types of fire extinguishers require regular maintenance, but the specific requirements vary slightly. Water and foam extinguishers need annual servicing and pressure testing every five years. Dry powder extinguishers require similar maintenance schedules. CO2 extinguishers need weight checks and valve inspections. Wet chemical extinguishers need particular attention to seals and pressure gauges. Professional servicing ensures all types remain effective when required.

P50 fire extinguishers don't require any annual servicing (just a quick visual inspection by a member of staff).

Can I use any fire extinguisher on electrical fires?

No, only specific types are safe for electrical fires. CO2 extinguishers are ideal because they don't conduct electricity and leave no residue. Dry powder extinguishers can also be used on electrical fires, though they create a mess. Water-based extinguishers such as water, water mist and foam can be used on fires involving live electrical equipment as long as they have been dielectrically tested in accordance with BS EN3. Always isolate power where possible before utilising any extinguisher.
