Dry Powder Abc Type

Description

The ABC-type dry powder fire extinguisher is one of the most universal and widely used types of firefighting equipment. It is known for its wide significance, it can fight fires involving light, ordinary, and high hazards. ABC dry powder extinguishers are specially designed to combat Class A fires (involving ordinary combustibles like wood, paper, and plastic), Class B fires (flammable liquids like gasoline), and Class C fires (flammable gases). Also, these extinguishers can be used on electrically actuated fires, making them an all-in-one solution for various fire emergencies.

ABC dry powder fire extinguishers are marked by a specific blue color band, which is easily observable in an emergency and helps users identify them quickly. These extinguishers are portable, making them perfect for a range of applications in industrial, domestic, and commercial settings. Made with high-quality components, they provide dedicated protection for multiple fire-prone environments.

Design and Performance of ABC Dry Powder

The ABC dry chemical powder used in these extinguishers is based on mono ammonium phosphate, a key agent that provides effective fire suppression. Additional additives are mixed into the powder to make it free-flowing, moisture-resistant, and frost-resistant, providing optimal performance even in difficult conditions. This formulation is highly effective in extinguishing fires involving various materials, such as wood, paper, cotton, rubber, and different types of plastics, as well as fires fueled by flammable liquids and energized electrical equipment. The addition of hydrophobic (water-repelling) agents controls the powder from caking during storage, making it just for high-risk environments like refineries, chemical plants, and airfields.

Extinguishing Mechanism

The extinguishing action of ABC dry powder is unique and highly effective. On Class B fires, it disrupts the combustion process by interfering with the chemical chain reaction that sustains the fire. For Class A fires, the particles in the powder fuse and swell, making a protective barrier or coating that cuts off the oxygen supply, thus extinguishing the fire and preventing re-ignition. This dual-action mechanism makes ABC powder highly effective across different types of fire hazards.

Applications

The ABC dry chemical agent is versatile, allowing it to be utilized for various fire types:

• Class A: Ordinary combustible materials including wood, cloth, paper, rubber, and many plastics.
• Class B: Flammable liquids, gases, and greases.
• Class C: Fires involving energized electrical equipment.

Variants

ABC dry powder extinguishers, such as those under the Flamax brand, are available in several MAP (mono ammonium phosphate) concentration variants to work different needs:

• Flomax ABC-20, ABC-30, ABC-40, ABC-50, and ABC-90: These versions offer varying levels of extinguishing effectiveness, with MAP concentrations that can be tailored for specific fire risk levels.
• Stored Pressure Extinguishers: These models use silicon-coated mono ammonium phosphate powder with MAP concentrations of 50% or 90%, meeting different customer requirements.

Features of ABC Dry Powder Fire Extinguishers

ABC dry powder extinguishers are packed with features designed for durability and efficiency:

• Deep Drawn Steel Cylinders: These provide strong, durable protection for the extinguishing agent.
• High Glossy Polyester Powder Coating: This durable coating improves the cylinder’s resistance to wear and corrosion.
• Brass Forging Valve: Heavy-duty, chrome-plated valve for added durability and reliability.
• Siliconized MAP-Based Powder: The powder is certified by BIS/IRS and UL-listed, providing high-quality, reliable fire suppression.
• Multiple MAP Variants: Available in 50% and 90% MAP concentrations.
• Helium Leak Tested: On request, stored pressure models can undergo helium leak testing to ensure airtight construction.
• Stainless Steel Option: Stainless steel-bodied models are available and come with BIS marking, enhancing resistance in demanding environments.
• BIS and CE Certifications: Cartridge-type models are BIS/IRS-approved and CE-certified for safety and quality compliance.

ABC dry powder fire extinguishers combine effectiveness with versatility, making them perfect for controlling many fire hazards across various settings. Their high-quality construction and diverse options allow them to complete specific safety requirements, providing a reliable solution for industrial, commercial, and domestic fire protection.
