Protection against fire risks is essential in any living, working, or industrial space. One of the most useful equipment used in fire safety is the DCP fire extinguisher.
Fires occur at times that one least expects, hence the importance of choosing the correct equipment can not be missed. DCP extinguishers are the professional equipment used to prevent different types of fires effectively and in the shortest possible time.
It is important to understand the mechanics of how they function and the areas in which they are most effective. I am going to cover every aspect of this equipment that will answer all your questions!
What is DCP Powder?
DCP powder is effective for all classes of fire – Classes A, B, C, and D. Dry chemical powder extinguishes the fire by pouring a thin layer of chemicals which isolates the fuel from the oxygen in the environment.
What Are DCP Fire Extinguishers?
Dcp fire extinguishers use fine chemical powder that extinguishes fire by suppressing the chemical chain of the fire triangle, namely heat, fuel, and oxygen.
There are two main types: basic which is suitable for most fire risks, and Specific which addresses particular threats.
How Do DCP Fire Extinguishers Work?
On discharge, the dry powder extinguisher expels a fine powder that forms a layer on the fuel cutting off its supply of oxygen in the fire.
This freezes the combustion process thus extinguishing the flames.
They are used in the case of class A, B, C, and D fires involving flaming solid, liquid fuels, flammable gasses, and electrical equipment respectively. Read more about fire extinguisher in Pakistan.
How to Use a DCP Fire Extinguisher
Using a dry powder extinguisher involves the following simple steps:
- Pull the safety pin which is located at the top of the handle to unlock it and to open the seal.
- By pointing the nozzle at the base of the fire, which is most likely the area of the highest density of fuel, the fire will be effectively attacked.
- Twist the handle clockwise/anti-clockwise with force to release the powder. Wave the nozzle from left to right across the base of the fire to put it out fully.
Where Should Dry Powder Fire Extinguishers Not Be Used?
It’s important to avoid using dry powder fire extinguishers in specific situations, such as:
- Class F fires (cooking fires, e.g., chip pan fires)
- Enclosed spaces: due to the risk of inhalation of the powder
- High voltage electrical fires (over 1000v)
- Fires involving flammable metals (unless using a specialist dry powder extinguisher)
