What is a dry chemical powder fire extinguisher used for?

There are just two types of dry chemical powder fire extinguisher available: standard and specialist. Standard dry powder extinguishers can extinguish almost any type of fire. Specialist dry powder extinguishers are for certain types of metal fires. However, because of the dispersal of powder, it’s important not to use them in enclosed spaces.

Dry powder extinguishers can also be known as ABC fire extinguishers, multi-purpose extinguishers or dry chemical extinguishers.

Standard dry powder extinguishers can be used on:

Class A fires – combustible materials: caused by flammable solids, such as wood, paper, and textiles
Class B fires – flammable liquids: such as petrol, paint or spirits
Class C fires – flammable gases: like propane and butane
Electrical fires – electrical equipment: such as computers and photocopiers
Specialist dry powder extinguishers can be used on:

Flammable metal fires: such as lithium (L2 powder extinguishers only)
All other flammable metal fires: (M28 powder extinguishers only)
Dry powder extinguishers should never be used on the following fire types:

Class F fires – cooking oils: such as olive oil or butter. Typically a chip-pan fire
Electrical fires: if the voltage exceeds 1000v
Flammable metal fires: unless it’s a specialist dry powder extinguisher
Identifying a Dry Powder Fire Extinguisher
Dry powder fire extinguishers have a blue coloured label stating ‘DRY POWDER’. It should also have a sign above or next to the extinguisher that states ‘Powder Extinguisher’.

Dry powder extinguishers sizes:

600g, 1kg, 2kg, 3kg, 4kg, 5kg, 8kg, 25kg, 35kg

How dry chemical powder fire extinguishers work？

These extinguishers work by smothering a fire and creating a barrier between the source of the fire and oxygen. However, because there’s no cooling effect with a dry chemical powder fire extinguisher, there’s a small change of the fire re-igniting.

When to choose a dry chemical powder fire extinguisher?

They’re suited to open or outdoor environments where there’s a fire risk from several different sources. An example would be a garage forecourt or a workshop, where there’s a fire risk present from fuel, vehicles, and chemicals.

Dry Chemical Powder Fire Extinguisher

What does a dry chemical powder fire extinguisher contain?

Dry chemical powder fire extinguishers are filled with monoammonium phosphate, an extinguishing agent that spreads easily and melts over flames. When the powder covers a fire, it blocks heat and oxygen, causing the fire to die down. Dry chemical powder fire extinguishers also act as a great heat shield.
