In the domain of firefighting sciences, every fire hazard is categorized into a particular class. This classification is mainly dependent on the flammable material, which causes fire. Ideally, you would want a material that can extinguish fire of any type and of any class. But there is no one-size-fits-all when it comes to extinguishing agents. However, dry chemical powder comes close, because it can manage a broad range of fire classes, namely, A, B, and C. In this blog, we are going to learn how a dry chemical powder (DCP) perfectly fits for an ABC fire extinguisher.
Purpose of ABC Fire Extinguisher
Before understanding why dry chemical powder is suited for ABC fire accidents, first understand its purpose. Class A involves ordinary combustible materials such as wood, paper, cloth, rubber, and plastics. Class B are the flammable liquids and Class C are the energized electrical equipment where water cannot be used because it is a conductive agent. As the ABC fire extinguisher handles all these fire classes, it is highly versatile equipment.
How DCP is Suitable For ABC Fire Extinguisher
Fine Mixture
A dry chemical powder is made in a fine composition so that it settles evenly on the flammable surface. We know that breaking the chain reaction can stop a fire, and the DCP creates a thin barrier between the fuel source and the flames.
Non Conductive
The chemistry of the powder contains phosphates and bicarbonates, which are electrically non-conductive in nature. Hence, these can be used for electrical fires (Class C). Most other hazards are either not applicable or used only for Class C fires.
Practically Simple
Quick response and easy use are some of the main qualities of any fire extinguisher. The mechanism to discharge the powder is uncomplicated and the powder stays stable in the cylinder. Overall, it is simple and doesn’t require special skills to operate the ABC fire extinguisher with dry chemical powder.
Water Repellent
Hydrophobic agents with water-repellent properties are added to this chemical powder. It prevents the cake-like clumps of residue after the extinguishing is complete. Other additives work as a flow enhancer to avoid accumulation.
Conclusion
In the ABC fire extinguisher, the mono-ammonium phosphate-based chemical agent is the right choice of material. It is easy to use, non-conductive, and acts quickly to extinguish fire. Given its excellent range of properties, it is applicable to tackle fire accidents of a diverse nature.
