ABC type Fire Extinguisher

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 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.

It insulates Class-A fires by melting at approximately 350–400 degrees F. The powder breaks the chain reaction of Class-B fires by coating the surface to which it is applied. It is safe and effective for Class-C fires since it is a non-conductor of electricity.

CO2 Fire Extinguisher

Carbon dioxide extinguishes flames, and some fire extinguishers, especially those designed for electrical fires, contain liquid carbon dioxide under pressure. Carbon dioxide extinguishers work well on small flammable liquid and electrical fires, but not on ordinary combustible fires, because although it excludes oxygen, it does not cool the burning substances significantly and when the carbon dioxide disperses they are free to catch fire upon exposure to atmospheric oxygen.

Carbon dioxide has also been widely used as an extinguishing agent in fixed fire protection systems for local application of specific hazards and total flooding of a protected space.

Mechanical Foam type Fire Extinguisher

Foam Type fire extinguisher is designed to be most effecive on class ' B ' fires, although they can also be used in class ' A ' fires. Foam is a powerful flame knockdown for spill fires involving flammable and volatile liquid like petrol, paints and alcohols.

In use these extinguishers form a thick blanket of foam over the burning surface, effectively cutting off the oxygen supply, thereby smothering the fire and preventing reignition.

Water type Fire Extinguisher

Water Type fire extinguisher for use against class 'A' fires involving carbonaceous material such as Wood, Paper, Plastic, Cloth & textile etc. Designed and constructed in accordance with IS : 940. Water knocks down fire rapidly by striking instantly cooling & penetrating the most deep seated "A" Class Fires.
