Recommended Uses: Vehicles, heavy machinery, and industrial applications. Cartridge-Operated Fire Extinguisher units store the dry chemical in a non-pressurized container and the propellant gas in a separate cartridge. Only at the time of use is the agent tank under pressure, and then only briefly. The cartridge operated units are ideal for heavy equipment; due to the vibration experienced, the chemical can settle and become compacted. The cartridge operated fire extinguisher was designed to counteract this. The gas is introduced to the agent through a tube designed to break up and “fluff” the dry chemical before it is expelled through the hose attached at the base for the tank.
ABC is a dry chemical that is very effective on fires involving ordinary combustible materials such as wood, paper, cotton, rubber, many types of plastics as well as fires involving flammable liquids and energized electrical equipment. Because of its versatility, ABC is most suitable for use on combination fires involving Class A, B or C type fires together.
BC is a dry chemical that is suitable for use on fires involving flammable liquid fires (Class B) including cooking oils, grease and energized electrical equipment (Class C).
- Purple K
Purple K is commonly used in high-risk areas such as: oil refineries, airport ramps, service stations, military facilities, naval warships, power plants, and other places where flammable liquids are handled. It is the most effective dry chemical in fighting class B (flammable liquid) or Class C (electrical) fires. Purple-K powder has an acrid taste and odor, is free-flowing, floating on most liquids, non-abrasive, does not wet with water and is compatible with most foam concentrates. It has violet color, to distinguish it from other dry agents. Purple-K is normally non-toxic, but ingestion of large amount can cause alkalosis. In high temperatures it decomposes to carbon dioxide and potassium oxide, which is toxic and highly corrosive.
Class D fire extinguishers contains a special blended Sodium Chloride based dry powder extinguishing agent. Heat from the fire causes it to cake and form a crust excluding air and dissipating heat from burning metal. Metal fires involving magnesium, sodium, potassium and sodium-potassium alloys can be successfully extinguished with this extinguisher. There is data showing that zirconium, uranium, titanium, and powdered aluminum fires can be controlled and extinguished with this unique extinguisher.
C02 fire extinguishers use carbon dioxide that is discharged as a white cloud of “snow” which smothers class B and class C fires by eliminating oxygen. It is effective for Class B flammable liquids and is electrically non-conductive. Carbon Dioxide is a clean, non-contaminating, odorless gas. Recommended for: Indoor use in furnace rooms, printing presses, pump rooms, electrical power panels, and laboratories where winds and drafts do not affect discharge.
