What is the difference between dry powder extinguisher and dry chemical fire extinguisher?

∙ 14y ago
The terms "dry powder" and "dry chemical", is used in regards to fire protection, refering to extinguishing agents.
Civilians, Lay persons and non-fire protection specialists use the terms interchangably. To be exact however, Dry Chemical refers to agents that extinguish Class A, B and C type fires, while Dry Powders refer to agents that extinguish Class-D type fires. Dry Chemicals have the consistancy of a flour like substance. Dry Powders have the consistancy of salt like substances. The difference is obvious to fire service professionals but not so for those who do not come in contact with the substances very often. Even the National Fire Protection Association confuses the issue when they use the word "powder" in their definition of a dry chemical.
NFPA 17 defines a dry chemical as: "a powder composed of very small particles, usually sodium bicarbonate, potassium bicarbonate, or ammonium phosphate-based with added particulate material supplemented by special treatment to provide resistance to packing, resistance to moisture absorption (caking), and the proper flow capabilities."

What is the difference between dry chemical and hcfc 123 fire extinguisher?
The difference between a dry chemical and a hcfc 123 fire extinguisher is the material used to extinguish. Dy chemical fire extinguishers typically contain a fine white powder composed mainly of monoammonium phosphate. This powder extinguishes the fire but creates a lot of smoke and is highly corrosive. Hcfc fire extinguishers use Halon instead. Halon is a liquefied, compressed gas that cuts off the combustion reaction while it is happening. Halon has very few risks and very little is needed to extinguish fires.
Should a dry chemical extinguisher or a pressure water extinguisher be used on an electrical fire?
You would not want to use a pressure water extinguisher on any electrical fire due to the possibility of electricity being conducted through the water and injuring someone.

DCP stands for Dry Chemical Powder, which is inside the extinguisher and is the actual fire suppressant. Basically, DCP is a type of ABC Extinguisher.
