Office Fire Extinguishers

Different types of fire extinguishers for offices

Most offices are best protected with water mist extinguishers, as they can tackle both common Class A fires (such as paper, wood, and fabrics) and electrical fires, covering the main risks found in office environments. While many workplaces still use a combination of CO2 and water extinguishers, CO2 is really only necessary where there are large volumes of valuable electrical equipment, such as in server rooms.

For office kitchens or canteens, the right protection depends on the cooking equipment in use. A wet chemical extinguisher is only required if there is a deep fat fryer or hob, as it is specifically designed to deal with cooking oil fires. In most other cases, a water mist extinguisher combined with a fire blanket will provide sufficient coverage for typical kitchen risks.

How many fire extinguishers does an office need?

The number depends on the size and layout of your office. As a general rule, you need enough coverage so that no one has to travel more than 30 metres to reach an extinguisher. For most small offices, two or three strategically placed fire extinguishers will suffice. Larger offices may require one per floor, plus additional units near high-risk areas such as server rooms or kitchens.

Where should office fire extinguishers be placed?

Position extinguishers near exit routes so people can grab them on their way out, not on their way in. Mount them at a height where everyone can easily reach them. Keep them visible and accessible, never tucked away behind furniture or in storage cupboards.

CO2 fire extinguishers are ideally located near server rooms and areas with a large volume of electrical equipment. Place water-based extinguishers in general office areas where paper and furniture fires are likely to start. If you have a kitchen with a deep fat fryer or hob, place a wet chemical extinguisher right where cooking occurs.

What size fire extinguisher is best suited for an office?

For most office applications, 6ltr water mist extinguishers are usually sufficient for all office risks. They're powerful enough to tackle typical office fires but light enough for most people to handle confidently.

Do offices need special fire extinguisher servicing?

Yes, all steel fire extinguishers need annual servicing to ensure they'll work when you need them most. This isn't just good practice, it's a legal requirement for most workplaces. During annual servicing, technicians check the pressure, inspect the extinguisher body for damage, and ensure all components are working correctly.

However, P50 Service-Free extinguishers are an exception. They don’t require annual professional servicing, only simple visual checks, making them a lower-maintenance and more cost-effective option.

Keep records of all servicing and inspections. Many insurance companies require proof of proper maintenance, and fire safety officers will want to see these records during inspections.

Frequently Asked Questions (FAQs)

Can modern office fire extinguishers replace both water and CO2 types?

Yes, newer water mist extinguishers can tackle both Class A fires and electrical equipment up to 1000V when used from a distance of more than 1 metre. This means you can often replace your traditional water and CO2 combination with a single extinguisher type, simplifying your office fire safety setup.

What makes service-free fire extinguishers different for offices?

Service-free extinguishers, such as the P50 Extinguisher models, don't require annual professional servicing, making them ideal for smaller offices or businesses that want to reduce ongoing maintenance costs. They're designed with extended-life technology that maintains reliability without regular professional checks.

Are refurbished fire extinguishers suitable for use in an office?

Refurbished CO2 extinguishers offer an economical solution for offices. These are high-quality UK reworked units that meet safety standards, but cost significantly less than new models, making them ideal for budget-conscious businesses that still require proper fire protection.

Why do server rooms need specific fire extinguisher types?

Server rooms and high-voltage areas need CO2 extinguishers because they don't conduct electricity and won't damage sensitive electronic equipment. The 2kg CO2 models are particularly popular as they're lightweight and easy to manoeuvre in cramped server room spaces. Understanding fire extinguisher types for live electrical equipment is crucial for making the right choice.

Can water mist extinguishers be used on office electrical equipment?

Yes, water mist extinguishers using microscopic water particles are safe for use on live electrical equipment up to 1000V, provided a distance of more than 1 metre is maintained. This makes them incredibly versatile for modern offices filled with computers, printers, and other electrical devices.
