ABC Dry Powder Fire Extinguisher

Spare Parts

Benefits: Cheap, Efficient, Multipurpose

ABC or Multi-Purpose dry chemical is a dry chemical extinguishing agent. It uses a specially fluidized and siliconized monoammonium phosphate powder. ABC dry chemical is usually a mix of monoammonium phosphate and ammonium sulphate.

In addition to the particle surface extinguishing effect of a Class B powder, Class
ABC powders have low melting/decomposition points in order of 150oC to 180oC,
and when these powders are applied to hot and smouldering surfaces, the
particle fuse and swell to form a barrier which excludes oxygen and thereby
completes the extinguishing process and prevents re-ignition.
