Types of Fire Extinguishers

Types of fire
  • Class A fires: Solids such as paper, wood, and plastic
  • Class B fires: Liquids such as paraffin, petrol, and oil
  • Class C fires: Gases such as propane, butane, and methane
  • Class D fires: Metals such as aluminium, magnesium, and titanium
  • Class E fires: Electrical Fires
  • Class F fires: Oil and Fat
Water Extinguisher (Class A fires)

Fires involving organic solid materials such as wood, cloth, paper, plastics, coal etc.

Water Spray Extinguisher (Class A fires)

Fires involving organic solid materials such as wood, cloth, paper, plastics, coal etc. These offer significantly improved fire fighting capability compared to traditional jet type water fire extinguishers.

Water Mist Extinguisher (Class A, B & C fires)

The first broad spectrum extinguisher to tackle A, B, C rated risks as well as fats and deep fat fryers (Class F). Models filled with de-ionised water tested with dielectric test to 35k Volts can be safely used on electrical fires (up to 1000 Volt) if a safety distance of 1m is adhered to, as their mist (de-ionised water) does not conduct electricity and the extinguisher does not normally form puddles, which could conduct electricity.

Powder Extinguisher (Class A C & F fires)

Can be used on fires involving organic solids, liquids such as grease, fats, oil, paint, petrol, etc but not on chip or fat pan fires. Can also be used on gas fires.

Dry Powder Extinguisher (A, B & C fires)

These specialist powder extinguishers are designed to tackle fires involving combustible metals such as lithium, magnesium, sodium or aluminium when in the form of swarf or powder.

Foam Extinguisher (A & B)

Fires involving solids and burning liquids, such as paint and petrol but not suitable for chip or fat pan fires. Safe on fires caused by electricity if tested to 35kV (dielectric test) and a 1m safety distance is adhered to.

Wet Chemical (Class F fires)

Wet chemical fire extinguishers are ideal for Class F fires, involving cooking oils and fats, such as lard, olive oil, sunflower oil, maize oil and butter.

Fire Blanket

Fire blankets are made of fire resistant materials. They are useful for smothering small pan fires or for wrapping round a person whose clothing is on fire. Fire blankets should generally be disposed of after use.
