This is the new style of labeling that shows this <br /> extinguisher may be used on Ordinary Combustibles, <br /> Flammable Liquids, or Electrical Equipment fires. <br /> This is the new labeling style with a diagonal red line <br /> ' drawn through the picture to indicate what type of <br /> fire this extinguisher is NOT suitable for. In this <br /> example, the fire extinguisher could be used on <br /> Ordinary Combustibles and Flammable Liquids fires, <br /> but not for Electrical Equipment fires. <br /> Types of Fire Extinguishers <br /> Dry Chemical extinguishers are usually rated for multiple purpose use. They <br /> contain an extinguishing agent and use a compressed, non-flammable gas as a <br /> propellant. <br /> Halon extinguishers contain a gas that interrupts the chemical reaction that takes <br /> place when fuels burn. These types of extinguishers are often used to protect <br /> valuable electrical equipment since thein leave no residue to clean up. Halon <br /> extinguishers have a limited range, usually 4 to 6 feet. The initial application of <br /> Halon should be made at the base of the fire, even after the flames have been <br /> extinguished. <br /> Water These extinguishers contain water and compressed gas and should only <br /> be used on Class A(ordinary combustibles) fines. <br /> Carbon Dioxide (CO2) extinguishers are most effective on Class B and C <br /> (liquids and electrical) fires. Since the gas disperses quickly, these extinguishers <br /> are only effective from 3 to 8 feet. The carbon dioxide is stored as a compressed <br /> liquid in the extinguisher; as it expands, it cools the surrounding air. The cooling <br /> will often cause ice to form around the "horn" where the gas is expelled from the <br /> extinguisher. Since the fire could re-ignite, continue to apply the agent even after <br /> the fire appears to be out. <br />
