What Are the Benefits of ABC Powder?

Different kinds of dry chemical extinguishing agents are employed in different types of fire situations. 

One is ABC Dry Chemical, also known as monoammonium phosphate. The efficiency of monoammonium phosphate powder is exclusively dependent on the powdered form of monoammonium phosphate that has been specifically fluidized and siliconized.

Differences between ABC Powder, BC Powder, and Dry Powder Extinguishers

“What is the difference between ABC powder extinguishers and dry powder extinguishers?” is a common question asked when discussing powder fire extinguishers.

The majority of dry powder extinguishers on the market today are ABC powder extinguishers, so the answer is that the two terms are pretty much synonymous. 

To be more specific, the majority of dry powder extinguishers use ABC powder, whereas the term “dry powder” refers to a particular type of extinguisher. Still, there are alternative ‘dry powders’ out there.

The Different Powder Extinguisher Types

ABC Powder

Ammonium or monoammonium phosphate is mixed with other powders to create ABC powder, which is used to increase bulk or improve flow. 

Class A, B, and C fires can be put out with ABC powder, also known as general purpose or multi purpose extinguisher powder.

BC Powder

Because it was popular before ABC powder became the standard, BC powder also known as standard powder is based on sodium bicarbonate.

Monnex Powder

Potassium bicarbonate is the ingredient in Monnex powder, which works wonders on oil and gasoline fueled fires. In comparison to powders like BC and ABC, Monnex powder is more costly.

Class “D” Powder

Class D powders are specialized powders that are applied with a low velocity discharge wand that drops the powder directly onto the fire. 

They are typically used on fires involving explosive metals, such as shavings or swarf made of magnesium and lithium. 

The powder itself melts and forms a glassy layer that covers the fire, absorbs heat, and keeps oxygen from getting to the fuel. 

For lithium ion fires, like those triggered by laptop batteries, these extinguishers are NOT appropriate!

What Are The Benefits? 

Typically, one part monoammonium phosphate and two or three parts ammonium sulfates are combined in ABC dry chemical processing. 

The former functions as an active component, whereas the latter is present in different quantities across the globe based on local standards. There are three possible mixtures between them: 40–60%, 60–40%, or 90–10%. 

1. Puts Out All Fires

Dry chemical powder is a commonly utilized method for putting out fires of all kinds. Its efficaciousness stems from its capacity to generate a dust layer that efficiently envelops the burning substance. 

Additionally, this powder interferes with the fire’s reaction, which makes it a powerful extinguishing agent. The gas cartridges inside the cylinder provide the pressure needed for it to function. 

Its range with this configuration is 3 to 4.5 meters (10 to 15 feet). Apply pressure for about 45 seconds.

2. Handles Typical Burning Solid Materials

ABC dry chemical powder acts as an insulator and has a melting point of approximately 180–200 °C (350–400 °F), making it a highly effective firefighting agent.

3. Suitable for Gases and Liquids

When used to put out fires involving liquids and gases, such as natural gas, propane, oil, and gasoline, the powder forms a coating on the affected surface, breaking the chain reaction of the fire. These kinds of fires are classified as Class B in the system.

4. ABC Powder Can Put Out Fires Started by Electricity

Because it’s essential to avoid using equipment that conducts energy back to the user, electrical fires pose a challenge. 

ABC dry chemical powder, which is safe and non-conductive for putting out electrical fires, works well in certain situations. These fires are categorized as Class C in the system, but they are classified as Class E in the system. 

It’s important to remember that, in other classes, electricity can also start fires.

5. Fits in Chimneys Without Any Problems

Chimney explosives are a commonly used tool by firefighters to put out chimney fires. The ABC dry chemical powder filled bags used in these chimney bombs are released down the chimney. 

They came into contact with the fire’s heat and the flue bottom. Let go of the powder. 

This chemical powder is then carried up the chimney by the natural draft, covering the creosote and extinguishing the fire. 

It might be required to use multiple chimney bombs, depending on how bad the fire is. Alternatively, these bombs can still work if they are opened before being dropped. 

It’s necessary to remember, though, that clearing the chimney may be required prior to using chimney bombs.


ABC dry chemical powder is a flexible fire extinguishing agent that can be used against a variety of fire types. 

It’s a great option for putting out fires started by common combustible materials, burning liquids and gases, and electrical equipment because it can separate the fuel from the oxygen in the air and stop the chemical reaction of fire.
