DCP Fire Extinguishers

DCry chemical Powder fire extinguishers are increasingly being used in homes and business premises. DCP fire extinguishers contain a chemical powder that eliminates the fire without causing damage to equipment and surroundings. DCP Powder is known for its efficiency in dry conditions. DCP Fire Extinguisher also stops poisonous gases from burning plastics or carpets, making it safe to use even indoors.

DCP Fire Extinguisher helps us fight fires without leaving any harmful residue behind. These Extinguishers are available in various sizes catering to specific fuels and fires. It’s a cost-effective solution for everyone who wants a safe environment at home and the workplace.

So of the best features, uses, and benefits of this blog!

What is a dry powder fire extinguisher?

Dry powder is a fire extinguisher designed to put out fires based on solid materials. DCP fire extinguishers are specifically designed for fires that involve electrical appliances, where it would be dangerous to use water or foam. This fire powder is also suitable for general household risks from cooking oil and similar flammable liquids.

Why it’s best?

– DCP dry chemical powder does not leave any residue after usage so that it can be used safely without the risk of contamination of equipment or damage to the environment

– It has a very effective knockdown power, so it can quickly put out flames, leaving the area safe

– DCP storage cylinder is made of durable stainless steel with an easy-to-use discharge horn. The safety valve is certified to the latest European Standard EN3.

– DCP fire extinguishers are available in different sizes, from 1 kg to 5 kg for home or office use. DCP powder is dry & non-corrosive, so it does not attack metal surfaces, making it perfectly safe for electrical equipment

– Must have for a room where there is an electrical appliance

What applications can DCP be used? 

DCP Fire Extinguisher is suitable for:

  • Business and industrial applications including server rooms, IT equipment, and laboratories
  • Kitchens where oil/flammable liquid fires may take place. DCF extinguishers have an excellent reputation for use with cooking oil risk fires
  • DCP dry chemical extinguishers will quickly put out electrical fires while leaving no residue or damage to equipment. DCP fire extinguisher is safe to use on electrical appliances, including computers, servers & electrical panels
  • DCF powder can be used safely around chemicals or flammable liquids that may risk people. These safety equipment are perfect for areas where water cannot be used due to harmful chemicals.
  • DCP Fire Extinguishers have a long shelf life and store safely for up to 4 years without the risk of deterioration, so DCF extinguishers will always be ready when needed.

How does a dry powder fire extinguisher work?

The dry chemical works by surrounding the burning material with a layer of chemicals that prevent further oxygen from reaching the fire. It also works by cooling the material below its ignition temperature.

DCPs operate as pressurized cylinders containing sodium bicarbonate and aluminum powder. When the cylinder is activated, it mixes these components, releasing carbon dioxide gas from the mixture. This causes pressure inside the dry chemical fire extinguisher to increase from a maximum of about 80 bar (1200 psi) up to a minimum of 120 bar (1800 psi).

The increased pressure forces a stream of dry powder out through the nozzle of the DCP fire extinguisher at around 40–50 liters per second. Because DCPs operate at relatively low pressures, they are limited in that they cannot be used on Class F fires involving cooking oil or fat. DCF fire extinguishers are also not suitable for fires involving burning metals, where the DCP will cause the molten metal to scatter.

What chemicals are involved in dry chemical powder fire extinguishers?

The dry chemical powder consists of a mixture of sodium bicarbonate (NaHCO3), with 6–10 percent moisture content, generally referred to as ‘C6/10’, and aluminum powder. DCP Fire Extinguisher contains different ratios of these components depending upon their application. DCPs for use against electrical fires contain around 60% NaHCO3, 10% Aluminium powder, and 30% water by weight, while DCF powders have only 11-14 % water by weight. DCP used in kitchens or garages needs to be powerful enough to extinguish oil or fat fires.

These fire extinguishers used in these areas have a slightly different formulation made with around 72% NaHCO3, 15% Aluminium powder, and 13% water by weight. DCP Fire Extinguisher is also used for fighting Class D combustible metal fires where DCF is not adequate. DCPs for this type of fire has a slightly different formulation containing 90% NaHCO3, 4-5 % Aluminium powder, and 5% water by weight.

Available Sizes?

Dry chemical powder fire extinguishers are available in sizes from 1 kg to 5 kg. DCP dry chemical powders are used extensively in homes, commercial kitchens, and garages, usually to protect against oil or fat fires.

Ideal for Class D fire

Dry chemical powder fire extinguishers are also used for Class D combustible metal fires. Dry chemical powders are specially formulated for this type of application.

To put out a DCP Fire Extinguisher fire, you should first try to douse the flames with water. DCP powder will boost the effectiveness of your water jet DC. If this is not possible, proceed as follows:

Steps to Use

1) Make sure that you wear suitable protective clothing (i.e., gloves and safety goggles).

2) Direct the stream at the base of the fire

3) Do not point directly at personnel involved in fighting the fire DC

4) Keep the DCP nozzle free from obstructions DCP Fire Extinguisher to avoid blockage DC

5) Do not direct DCP onto burning liquids DC

6) Best used on Class B fires involving combustibles DC

7) Read manufacturer’s instructions before using DCP Fire Extinguisher. DCP Dry Chemical Powder are not for use on live electrical equipment.

8) Follow manufacturer’s safety precautions when using this type of extinguishing agent


9) DCP are not recommended for use on Class D fires, including combustible metals DC

10) DCP is unsuitable for use on class F fires involving cooking oils or fats DCV

Hazards of DCP Fire Extinguisher?

Dry chemical powder extinguishers are classified as ‘B: E’ types under the revised European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR). Dry Chemical Powder Fire Extinguisher contains chemicals that pose a low health risk. However, when the dry chemical powder is in contact with the skin, it can irritate.

Final Words:

Proper training and correct maintenance of DCP Fire Extinguisher will ensure that these Fire safety equipment are working effectively. If you are a building owner and want to protect it from unwanted fire hazards, contact well-reputed fire safety equipment suppliers only.
