A range of stored pressure Dry Chemical Powder extinguishers are suitable for A, B or C class fires or a combination of ABC class fires. All the extinguishers supplied conform to the minimum fire ratings as specified in SANS 1910:2009.

The powders are siliconised for superior flow and anti-caking.

Dry Chemical powder fire extinguishers are the most widely used of all types of extinguishers. These multi-purpose extinguisher interferes with the combustion process and provides rapid fire knock down. They are ideal for mixed fire risk environments and especially suited for the protection of liquids, storage of liquid gases and heating oils used for industry, garages and workshops.

Multipurpose ABE powder is a versatile extinguishant which is used to extinguish Class A (carbonaceous) fires achieved by sealing burning embers, it is also used on Class B (flammable liquid) fires and Class E (electrical) fires.

Advantages: Powder provides a rapid ‘knock-down’ for a range of fires types. When dry it may be cleaned up with a vacuum cleaner.

Disadvantages: On discharge, the extinguisher forms a dense cloud of powder which may temporarily restrict vision and may cause respiratory irritation. AB(E) powder, when it contacts very hot objects, can melt and form a film which may be difficult to remove. After initial ‘knock-down’, it gives no protection against re-ignition of flammable liquid fires. While B(E) powder is not effective on class A fires, AB(E) powder is not effective on fires involving cooking oils and fats.
