Fire extinguishers everywhere The fire extinguishers are designed to put out or control small fires. It is important that we equip facilities with the proper fire extinguishers as part of fire protection plan.
Air-pressurized water extinguishers Water is one of the most commonly used extinguishing agents for type A fires. Always you can recognize an APW by its large silver container. They are filled about two-thirds of the way with ordinary water, pressurized with air. APWs are designed for Class A (wood, paper, cloth, rubber, and certain plastics) fires only.
Carbon Dioxide extinguishers This type of extinguisher is filled with Carbon Dioxide (CO2), a non-flammable gas under extreme pressure. These extinguishers put out fires by displacing oxygen, You can recognize this type of extinguisher by its hard horn and absent pressure gauge. CO2 extinguishers are designed for Class B and C (flammable liquid and electrical) fires only.
Dry Chemical extinguishers Dry chemical extinguishers put out fires by coating the fuel with a thin layer of fire retardant powder, separating the fuel from the oxygen. The powder also works to interrupt the chemical reaction, which makes these extinguishers extremely effective. Dry Chemical extinguisherswill have a label indicating they may be used on class A, B, and/or C fires. OR
