They are also safe for use on live electrical equipment, making them an ideal replacement for the AFFF foam extinguishers which will soon be subject to international restrictions.

Can water mist extinguishers be used on cooking oil fires?
Traditional water extinguishers deliver a jet of water which penetrates the surface of the burning fat, sinks because it is heavier than fat, and almost instantly evaporates. This rapid expansion pushes the burning fat out of the pan or deep fat fryer, creating violent flares and spreading the fire. With a water mist extinguisher; most of the droplets evaporate above the fat creating a cooling ‘blanket’ reducing the oxygen from the surface and preventing re-ignition. That is why our water mist extinguishers are suited to fight small F-Class fires such as on shallow frying pans and domestic deep fat fryers (typically 2 to 3 litres). On larger fat and cooking oil fires, such as commercial deep fat fryers, there is a larger surface area burning and a much larger volume of oil to cool, which may still be disturbed by the instant evaporation of the water mist droplets; for this reason, we recommend a wet chemical extinguisher for fires above a 5F rating.
Are water mist extinguishers environmentally friendly?
Water mist fire extinguishers contain only de-ionised water, meaning that no chemicals are released into the environment on discharge. This makes water mist extinguishers a sustainable and eco-friendly option, suitable for most common types of fire in schools, offices, and other public buildings.
What are water mist extinguishers used for?
Our water mist extinguisher is suitable for extinguishing A, B, and C type fires, including live electrical equipment, as it has been tested up to 35,000 volts and contains only de-ionized water, which does not conduct electricity. These units are well-suited for various settings such as in the home, offices, nurseries, schools, churches, HMOs, and areas where a messy discharge would pose a problem.
How do water mist extinguishers work?
Our versatile water mist fire extinguishers, sometimes referred to as 'dry' water mist because of their production of microscopic water droplets, represent innovative firefighting technology. The supersonic nozzle design of these extinguishers generates a mist curtain that diminishes the oxygen supply fuelling the fire, thus extinguishing the flames. Additionally, it forms a highly efficient cooling layer over the burning material, effectively preventing re-ignition.
Where can water mist extinguishers be used?
Water mist extinguishers are suitable for multiple locations, they are especially appropriate for use in schools, nurseries and anywhere where children or vulnerable people are present. The discharge of the water mist extinguisher is at low pressure and not harmful; the water itself is of course completely harmless. The dry water mist extinguishers can be installed in HMOs; they are easy to use and can be used on all common household risks ensuring users face no confusion or risk of misapplication when dealing with fires. These units are environmentally friendly and use de-ionised water therefore are free of residue. Water mist fire extinguishers are also efficient on clothing fires, extinguishing the fire immediately and cooling the area affected without causing harm to burns or the person. Clothing and textiles are solid combustibles, making them a Class A fire risk. Water Mist extinguishers have been shown to be very effective against this type of fire. This is ideal for retail premises, as nearby clothing which has not yet caught fire will not be damaged upon discharge.
