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 Fire Extinguisher?
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.
DCP fire extinguishers are available in different sizes, including
What is the Content of DCP Fire Extinguisher?
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.
DCP Automatic Fire Extinguisher
Automatic Fire Extinguisher is an efficient solution for fighting Class A, B, and C fires.
It is ideal for industrial and commercial spaces. It works by releasing a fine powder that extinguishes flames, cutting off oxygen and stopping the chemical reaction fueling the fire.
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,s thus extinguishing the flames.
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)
How to Identify DCP Fire Extinguishers
You can identify a dry powder extinguisher by its distinctive color coding—usually blue with a white band. It’s also known as DCP (Dry Chemical Powder) or ABE (Ammonium Phosphate Base Extinguisher), depending on the chemical composition.
Alternate Names for Dry Powder Fire Extinguishers
A dry powder fire extinguisher is also known as:
- Dry chemical fire extinguisher
- ABC fire extinguisher
- Multi-purpose fire extinguisher
- Dry powder fire extinguisher
- Dry chem extinguisher.
Pros and Cons of DCP Fire Extinguishers
Pros
- Multi-talented: Dry chemical extinguishers are used on class A, class B, class C and class E fires.
- Fast Action: They can brag of rather high fire knockdown rates that are understood as the ability to quickly stop fire.
- Adaptable: These extinguishers are multipurpose which is ideal for areas with varying fire risks and hazards.
Cons:
- Should not be used in indoor areas: Because of the inhalation risk, they are not suitable for use in confined environments.
- Harmful for some appliances: The substance in the powder can be injurious to sensitive electrical appliances.
Installation of DCP Extinguishers
Geentech also installs DCP exitnguishers wherever you want, but if you want to do it yourself,f then follow these guidelines for proper installation,
- Determine the Location: Install the extinguisher near fire-prone areas, such as kitchens, workshops, storage areas.
- Mount at Accessible Height: The extinguisher should be mounted on a sturdy wall bracket with the top handle not higher than 4 feet (1.2 meters).
- Ensure Visibility: Place the extinguisher in a visible and clear location.
- Maintain Clearance: Ensure no objects block access to the extinguisher.
- Install Near Exit Points: Position extinguishers near exits for safe access during emergencies.
- Regular Inspections: After installation, check for secure mounting, proper pressure levels, and functional parts. Conduct routine maintenance to ensure readiness.
DCP Powder Price in Pakistan
DCP powder fire extinguisher price in Pakistan is around Rs. 2,500 for 2kg. However, price may vary depending upon size, and brand. GreenTech offers DCP powder at reasonable price. To get further details, feel free to contact 0321-1719229.
What to do if You Inhale Fire Extinguisher Powder?
While extinguishing a fire, you might occasionally inhale some of the powder. Although extinguisher powder is typically non-toxic, still, it can irritate your lungs and airways.
If you start coughing, sneezing, or experiencing difficulty breathing after using a fire extinguisher, here’s what to do:
Seek medical attention immediately if you experience:
- Severe or persistent coughing or wheezing
- Difficulty breathing
- Chest tightness
- Burning or stinging in the eyes
What is the Difference Between DCP and CO2 Fire Extinguisher?
Frequently Asked Questions
DCP stands for dry chemical powder.
The dry chemical powder used in most ABC fire extinguishers is non-toxic, but it can cause skin irritation upon contact. If you come into contact with the powder, wash the affected area with soap and water.
Dry powder fire extinguishers are highly versatile and can be used in many environments, including workshops, kitchens, garages, and warehouses.
DCP fire extinguisher contains Dry Chemical Powder, usually monoammonium phosphate.
Fire extinguishers are color-coded to indicate their specific use:
- Red – Water-based extinguishers (spray and mist)
- Blue – Dry powder extinguishers for multiple fire types
- Cream – Foam extinguishers for flammable liquids
- Black – CO₂ extinguishers for electrical and liquid fires
- Yellow – Wet chemical extinguishers for cooking oil fires
- Purple – Clean agent extinguishers for sensitive equipment
Wrapping Up
The DCP Fire Extinguisher is one of the most powerful tools used in fire fighting since it is used in fighting most of the classes of fires.
If you want to maximize your fire safety readiness, you must know how it works and when it is best to use it.
