Dielectrical testing is carried out on fire extinguishers to determine whether they are safe for use on electrical equpiment. If the contents conducts electricity, it will not be safe for this use. Once the extinguisher has passed this 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).

Yes, extinguishers can be refilled after discharge. All our extinguisher ranges can be refilled after you have used them.
In addition to this, powder, foam and water extinguishers will require a discharge and refill after 5 years and CO2 fire extinguishers after 10 years. P50 service free extinguishers do not require service or refilling for ten years.
If you have extinguishers that need refilling, contact firstname.lastname@example.org.
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 to 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, it is 'a fire involving live electrical equipment'. The use of, for example, a simple water extinguisher on this type of fire could lead to electrocution of the person fighting the fire. Our section of electrically safe extinguishers will help you select a suitable extinguisher for your building or application.
Some foam extinguishers are dielectrically tested and can therefore be used on or near the fire. You need to carefully read the product description to see if they're suitable for use "near" or "on" live electrical fires. A new solution is the dry water mist extinguisher that uses de-ionised water which cannot conduct electricity. It has a very fine mist generation that does not pool and protects the user from both fire and electrocution. View our range of extinguishers for electrical equipment.
AFFF foam contains PFAS chemicals, which have been identified as being harmful to the environment, people, and wildlife. Some PFAS chemicals have been banned since 2020, and other legal restrictions are imminent. This new legislation is expected to enforce a ban on the manufacture, sale and eventually ban the use of all AFFF foam extinguishers in the UK.

HGVs carrying dangerous goods require dry powder extinguishers and must comply with The Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations (CDG) where the minimum amount of dry powder depends on the vehicle tonnage. To find out the requirements for your vehicle, please see the summary of minimum dry powder requirements.
Water mist extinguishers are real multi-purpose fire extinguishers capable of tackling the most common types of fire:
This includes waste bins, clothing, wooden furniture, soft furnishings, curtains and small gas appliances, making them ideal for a wide range of environments from homes to offices, workshops to churches, and even schools.
