6ltr Water Mist Fire Extinguisher - Act Fire

De-ionised water mist extinguishers are serviced in the same way foam and water fire extinguishers are. Steel extinguishers require an annual service by an engineer and a refill with de-ionised waterevery 5 years. For service-free P50 fire extinguishers with de-ionised water, the customer can carry out and record a simplified annual inspection. This type of extinguisher only requires a refill (and factory refurb) every ten years.

Yes, de-ionised water mist fire extinguishers have passed the di-electrical conductivity test, which marks them as safe for use on live electrical equipment up to 1,000V. Two key factors differentiate water mist fire extinguishers from traditional water or foam units: 

• Water mist extinguishers are filled with de-ionised water, which cannot carry electrical current.

• The microscopic droplets that form the signature mist are too small and too far apart for electricity to flow through them.

No, water mist extinguishers are probably the most environmentally-friendly extinguishers on the market. Our water mist extinguishers contain only de-ionised water – there are no chemicals in the extinguishers. This makes the discharge environmentally friendly and any spill or residue can be easily cleaned up.

Water mist extinguishers have been certified for use on Class F fires (cooking oils and fats), however following our own independent research, Safelincs does not recommend using water mist on anything above a 5F-rated fire (this is equivalent to an average domestic deep fat fryer). For class F fires above a 5F rating, we recommend a wet chemical extinguisher.
