Be accurate when using as they have a short to moderate spray range and last only 10 to 25 seconds.īe cautious of the residue after using dry chemical extinguishers. The powder also works to break the chemical reaction. The extinguishers discharge a blanket of fine powder which creates a break between the fuel and the oxygen in the air. These extinguishers will be marked for the classes they are designed to extinguish (e.g., ABC type extinguisher will put out Class A, B and C fires).

Do not use CO 2 extinguishers for Class A fires because the fire may continue to smolder and re-ignite after the CO 2 disperses.ĭry Chemical extinguishers: Dry chemical extinguishers are the most common and available in few types.Only use in a confined space if workers have appropriate respiratory protection. Do not use CO 2 extinguishers in confined spaces as CO 2 can displace the oxygen in the air, making breathing difficult.A hard horn attached to the end of the spray tube helps to contain and aim the spray at the target area. It has a moderate spray range and last only 10 to 30 seconds. Be thorough when using a CO 2 extinguisher. When used for Class B and C fires, the CO 2 covers the fuel by blanketing it, and stops the reaction at the surface by displacing oxygen. Water is ineffective as it helps to spread the liquid and the fire.Ĭarbon Dioxide (CO 2) extinguishers: The extinguishing media is pressurized CO 2. Do not use water to extinguish flammable liquid or cooking oil fires.Water is a good conductor and can increase the possibility of electrocution.

Do not use water to extinguish an electrical fire.When used for Class A fires, these extinguishers remove the heat from the burning materials. Water extinguishers: Water extinguishers are filled about two-thirds with water and then pressurized with air.
