Types of Fire Extinguishers

Would you know which fire extinguisher to use in an emergency?  There are 8 different types of fire extinguisher to deal with a multitude of different fire classes.

Water

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

Water Spray (Water with additive)

For 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 (Dry Water Mist)

For tackling A, B, C rated risks as well as fats and deep fat fryers (Class F). Models 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.

Dry Powder (Multi-Purpose)

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 (Special Powders)

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 (AFFF)

For 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.

Carbon Dioxide

For live electrical equipment, although it allows re-ignition of hot plastics. Now mainly used on large computer servers, although care has to be taken not to asphyxiate people when using the extinguisher in small server rooms.

Wet Chemical

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.
