Choosing the right one
When using a fire extinguisher it’s important to select the correct suppressant for the flammable material in question. Failure to do so may increase the fire hazard and pose a danger to the operator – e.g. you should never use a water fire extinguisher if you suspect an electrical hazard.
UK Fire Safety Systems offer a comprehensive selection of fire extinguishers to combat different classes of fire. If in doubt, please contact one of our experts for our professional opinion.
YEARS OF EXPERIENCE
- Water fire extinguishers: Class A fires ONLY – solid materials including wood, paper, textile carpets, clothing/curtains etc.
- Foam fire extinguishers: Class B fires – flammable industrial liquids, including diesel, petrol, industrial oils, greases, and paints. Foam extinguishers can also be used to combat Class A fires.
- Powder fire extinguishers: There are three types of powder fire extinguisher, designed to combat various fire hazards:
- Class C fires – flammable gases (in compressed liquid or gaseous form), including propane, hydrogen, natural gas, and methane. Powder fire extinguishers are also suitable for fires caused by mixed materials, or when you are unsure of the source.
- Class D fires – flammable metals, including aluminium, magnesium, and sodium, but not lithium.
- Class D Lithium – Specialist powder extinguishers designed for use with lithium fires. Also compatible with other metal fires.
- CO2 fire extinguishers: Suitable for use with all electrical fire hazards. Carbon dioxide does not damage electrical and computer equipment, so is ideal for combating localised fires in office environments without risk of damage to IT assets.
- Chemical fire extinguishers: Class F fires – flammable domestic liquids, including olive oil, sunflower oil, vegetable oil, butter, and animal fat.
