High Flow (ABC/Purple K) FIRE EXTINGUISHER INFORMATION

 

The quick discharge rate enables the dry chemical agent to reach fires faster, providing increased firefighting capability as compared to a standard fire extinguisher.

 

They are available in ABC or Purple K agent. A Sentry High-Flow Stored Pressure fire extinguisher has a dry chemical capacity of 10 lb or greater with a discharge rate of 1 lb per second or greater, which complies with NFPA 1: Standard for Portable Fire Extinguishers.

 

The higher discharge rate allows a greater volume of dry chemical agent to be applied to the fire. This provides an increased firefighting capability when compared with standard fire extinguishers.

 

The High-Flow Stored Pressure fire extinguishers are designed for propane filling and storage facilities, hazardous construction sites, maintenance facilities, hazardous material cabinets, small paint booths and repair facilities, marinas, salvage and recycling facilities, warehouses and storage facilities.

 
 

“A” GARBAGE–WOOD–PAPER

Fire extinguishers with a Class A rating are effective against fires involving paper, wood, textiles, and plastics. The primary chemical used to fight these fires is monoammonium phosphate, because of its ability to smother fires in these types of materials.

“B” LIQUIDS

Fire extinguishers with a Class B rating are effective against flammable liquid fires. These can be fires where cooking liquids, oil, gasoline, kerosene, or paint have become ignited. Two commonly used chemicals are effective in fighting these types of fires. Monoammonium phosphate effectively smothers the fire, while sodium bicarbonate induces a chemical reaction which extinguishes the fire.

“C” ELECTRICAL EQUIPMENT

Fire extinguishers with a Class C rating are suitable for fires in “live” electrical equipment. Both monoammonium phosphate and sodium bicarbonate are commonly used to fight this type of fire because of their nonconductive properties.
