A range of fire extinguishers for use on or around live electrical equipment, including traditional powder and CO2 extinguishers. We also offer water mist fire extinguishers that have been di-electrically tested in accordance with EN3-7. These extinguishers use de-ionised water and a specially designed spray nozzle dispenses a fine mist which ensures they are safe to use on or near live electricity.

One of the most popular extinguishers on the market, a 6l foam offers protection against class A & B fires. Most commonly found in offices and public areas.
With high fire ratings, these extinguisher units are often installed on caravan parks, ideal for extinguishing burning wood, furniture and flammable liquids.
Dielectrical testing verifies that even with an incredibly high voltage of 35000 Volt, no electrical current can flow back to the person discharging an extinguisher on a fire involving live electricity. Certain test distances between user and fire apply for this test. Once the extinguisher has passed this stringent test, it is still limited for safety reasons for use on maximum 1000V and a minimum distance between extinguisher and fire of 1 meter (1000V is four times the voltage used in a domestic building!).
If a liquid is used on a fire involving live electricity there is still a risk of a pool of liquid forming and if this liquid is able to transport current there could be a risk to the user from electrocution if the user stands in the pool. However, one has to keep in mind that the use of any liquid on live electrical equipment usually leads to immediate fuse-triggering. So the pooling issue is more theoretical.
Our dry water mist extinguishers apply de-ionisde water and discharge an extremely fine spray. Pooling is almost impossible and in addition, de-ionised water cannot carry electrical current, so dry water mist extinguishers are a new option to fight electrical fires and cause minimum damage to the equipment on fire by the fire fighting agent.
Strictly speaking there is no such thing as electrical fire, as electricity does not burn. Neither do the cable cores and other conductors. However, electrical current can heat up other materials and start fires. Often, it is the cable covering or foreign bodies in the electric equipment start start to burn first.
If the electric supply to the equipment on fire continues we speak of a fire involving live electrical equipment and the use of, for example, a simple water extinguisher could lead to electrocution of the person fighting the fire. When planning extinguishers for your business or home you therefore need to consider the electrical equipment eg laptops, printers, kettles or washing machines. Our section of electrically safe extinguishers will help you select a suitable extinguisher for your building or application.
Which extinguishers are suitable for electric equipment?
Traditionally, CO2 extinguishers are used for electric equipment, as the CO2 gas does not carry electricity. However, CO2 gas can drift off and the fire can re-ignite.
Powder extinguishers were also used in the past, as they are powerful and do not conduct electricity. However, they are not recommended for use indoors any longer, as they cause inhalation issues and can cloud the escape route.
Dry water mist extinguishers use de-ionised water which cannot conduct electricity combined with a very fine mist generation that does not pool and protects the user from both fire and electrocution.
