A mechanical foam fire extinguisher is designed to combat Class A (ordinary combustibles) and Class B (flammable liquids) fires. It utilizes a specialized agent known as Aqueous Film Forming Foam (AFFF) to extinguish flames.
Description
How it Works
AFFF:This agent creates a blanket of foam on the fire's surface, separating the fuel from the oxygen in the air.This process, combined with cooling, effectively smothers the fire.
Mechanical Operation: The extinguisher uses a mechanical system to generate foam. This system typically involves a cartridge containing compressed gas that mixes with the AFFF solution when activated, producing foam.
Key Features
Effective against Class A and B fires:Suitable for fires involving solids like wood, paper, and cloth, as well as flammable liquids like gasoline and oil.
Rapid fire suppression: The foam blanket quickly extinguishes the fire and prevents reignition.
Environmentally friendly:AFFF agents are generally biodegradable and have minimal environmental impact.
Portable: Available in various sizes, making them suitable for both residential and commercial use
