![]() This is important to ensure that the media is non-conductive and bacteria-free. When researching products we would recommend that you ensure that the mist extinguisher in consideration is charged with de-ionised water and not just ordinary water. Tests show absence of legionella bacteria over the lifespan of a fill. De-ionised water also restricts bacteria growth. In contrast to powder extinguishers, water mist extinguishers also eliminate the risk of powder inhalation in small spaces such as boats or small kitchens. The water mist is also suitable for churches and historic buildings as the water mist does not saturate the objects in the building as a traditional water extinguisher would and has no harmful substances that could chemically damage wood or soft furnishing. Refills are relatively cheap and disposal at the end of the extinguisher life is no problem. The water mist discharge can even be safely pointed at people if their clothes are on fire. The discharge from water mist extinguishers with de-ionised water is completely non-conductive, leaves no residue and can be used in food preparation areas and clean rooms. This offers customers significant savings. They have been di-electrically tested with 35,000 Volt for user safety and are therefore safe for use on live electrical equipment of up to 1000 Volt (1m safety distance).Īs only one extinguisher type is required for almost all locations, water mist extinguishers do reduce the risk of confusion and can replace typical fire points consisting of a CO2 and a traditional water-based extinguisher with just one single fire extinguisher. Water mist extinguishers with de-ionised water are ideal for offices, public buildings, such as schools, but are also excellent general household fire extinguishers. Water mist extinguishers are nevertheless suited for B and C fires. Hence the limited number of classes stated on the front of all water mist extinguishers. Please note that the current certification standards do not allow yet the the formal certification of water-based extinguishers on B and C fires. They are capable of extinguishing class A (solids), class B (flammable liquids) and class C (flammable gasses) fires. This has the effect of providing a much higher fire rating than a plain water extinguisher.Portable water mist extinguishers with de-ionised water are broad spectrum fire extinguishers. ![]() ![]() This increases the effectiveness of the water, cooling and damping down the burning substance at a much faster rate. The additive in the Water Additive fire extinguisher serves to reduce the surface tension of the water, which makes the water softer making it soak into the material much quicker. One of the key issues when using water as a fire fighting medium is that it can take some time to absorb into the material, the water just sitting on the surface of the fuel as opposed to soaking in – therefore reducing it effectiveness. Water Additive Extinguishers – MAKING WATER WETTER! This fact has an added benefit in that it helps to prevent flashbacks – this is when although the fire seems to be extinguished, the residual heat is sufficient to re-ignite the fire. ![]() Water fire extinguishers tackle the fire by cooling the burning materials below the level of heat required of spontaneous combustion. ![]() Water is the oldest known method of extinguishing fire, and is still as effective as it ever was! Its use is limited to most burning solids, including wood, paper, textiles and other carbonaceous materials. ![]()
