Description

Trolley fire extinguishers are typically rated for use on Class A fires (fires involving flammable solids such as wood), Class B fires (Flammable liquids or gases) and Class C (fires involving electrical equipment due to, for example, faulty wiring).

A class A fire extinguisher typically uses dry powder to produce foam and a dry nitrogen propellant. The powder contains ammonium phosphate (MAP) as well as silicates and filler material. This is also known as a DCP fire extinguisher (for ‘dry chemical powder’).

East Rand Fire supplies and services dry powder, water, and foam-based standard fire extinguishers.
