Description

Trolly Monoammonium phosphate, ABC Dry Chemical, ABE Powder, tri-class, or multi-purpose dry chemical is a dry chemical extinguishing agent used on class A, class B, and class C fires. It uses a specially fluidized and siliconized monoammonium phosphate powder. ABC dry chemical is usually a mix of monoammonium phosphate and ammonium sulfate, the former being the active one. The mix between the two agents is usually 40–60%, 60-40%, or 90-10% depending on local standards worldwide. The USGS uses a similar mixture, called Phos Chek G75F.

The Powder Fire Extinguisher ABE, distinguished by a white coloured band around the top of the cylinder, is the most widely used type of fire extinguisher suited for fires occurring in the house, boat, garage, car or caravan.

They discharge a fine powder that absorbs fuel molecules, depriving the fire of a fuel source.

Powder Fire Extinguishers are available in a range of sizes for domestic and industrial situations including 1.0kg, 1.5kg, 2.0kg, 2.5kg, 4.5kg and 9.0kg models. The ABE range also offers a 4.5 kg high performance fire extinguisher.

Fire extinguishers are designed to tackle specific types of fire. There are six different classes of fire and several different types of fire extinguishers.
Classes of fire

• Class A – fires involving solid materials such as wood, paper or textiles.
• Class B – fires involving flammable liquids such as petrol, diesel or oils.
• Class C – fires involving gases.
• Class D – fires involving metals.
• Class E – fires involving live electrical apparatus. (Technically ‘Class E’ doesn’t exists however this is used for convenience here)
• Class F – fires involving cooking oils such as in deep-fat fryers.
