Water Spray Extinguisher (Water with additive) :
Fires involving organic solid materials such as wood, cloth, paper, plastics, coal etc. These offer significantly improved fire fighting capability compared to traditional jet type water fire extinguishers. Available in 3 and 6 litres.
Water Mist Extinguisher (De-Ionised Water) :
The first broad spectrum extinguisher to tackle A, B, C rated risks as well as fats and deep fat fryers (Class F). Models filled with de-ionised water tested with dielectric test to 35k Volts can be safely used on electrical fires (up to 1000 Volt) if a safety distance of 1m is adhered to, as their mist (de-ionised water) does not conduct electricity and the extinguisher does not normally form puddles, which could conduct electricity. The UltraFire water mist extinguishers contain only de-ionised water which cannot carry any electric current.
