Fire Extinguishers for Offices

One of the main fire risks in modern office environment is electrical equipment with workstations containing computers, stereos, kettles, shredders etc. Using foam or powder extinguishers near to electrical equipment such as computers can cause damage / or create mess that may require careful clean up to the surrounding area, we therefore recommend the use of residue-free extinguishers such as water mist extinguishers containing de-ionised water.

Please note that any liquid-based extinguisher used must be certified safe for use on electric equipment. Water mist extinguishers contain de-ionised water and are safe to use on live electrical equipment up to 1000V from a distance of 1m.

Water Mist Extinguisher

Water Mist Extinguisher with de-ionised water provide fire fighting for class A, B, C and Electrical risks. In an office environment these water mist fire extinguishers provide users with a multi-purpose unit with next to no residue meaning reduced clean up. As de-ionised water cannot conduct electricity, these extinguishers are safe on live electrical equipment of up to 1,000 Volt at 1m distance.

Water mist units can be used on a multitude of fire risks and are therefore ideally located in areas with untrained users, where a single extinguisher type can be used to tackle all hazards.

Fire Classification

Water Mist Fire Extinguishers are suitable for use on the following types of fire.

CO2 Fire Extinguishers – Ideal for Computers and Servers

With today's office environments containing computers, printers, radios, heaters etc, it is important to have the necessary fire fighting equipment to hand. A CO2 fire extinguisher has the capability of putting out fires fuelled by electrical equipment by depriving the fire of oxygen.

With CO2 fire extinguishers working on the principle of suffocating fires, the same danger can apply to humans so it is unadvisable to use a CO2 fire extinguisher in confined areas where the flow of air may be limited.

P50 Water Mist Service-Free Fire Extinguishers

P50 Water Mist Service-Free Fire Extinguishers are an ideal all-rounder for use in most reception areas. Giving excellent coverage for class A (solid combustibles) fires, the P50 water mist is dielectrically tested, making it safe for use on live electrical equipment such as computers or lighting (up to 1000 V electricity from 1m distance).

The P50 Water Mist Extinguisher can be used as a replacement for a traditional foam and CO2, or water and CO2 combination. Having one single unit to tackle all fires reduces the risk of the wrong extinguisher being used in the event of a fire. P50s are also ''service-free'', meaning they do not require servicing annually by a technician. Switching to P50 extinguishers could save you up to 50% on the cost of your fire extinguishers.
