A Class A fire extinguisher can be safely used on which type of fire?

• A. Oil
• B. Electrical
• C. Wood
• D. Chemical

Answer: (C)

A Class A fire extinguisher is specifically designed to combat fires that involve ordinary combustible materials such as wood, paper, cloth, and some types of plastics. These materials ignite easily and burn rapidly, making extinguishing agents like water or foam effective in cooling the material and removing the heat required for the fire to continue. When faced with a fire involving wood, the Class A extinguisher's purpose is to suppress the flames by breaking the fire triangle – heat, fuel, and oxygen. Water is the most common agent used in Class A extinguishers to lower the temperature of the burning material and prevent reignition. In contrast, using a Class A extinguisher on fires involving oil, electricity, or certain chemicals is not suitable due to the risk of spreading the fire, causing electrical shock, or generating toxic fumes. Therefore, recognizing the appropriate application of fire extinguishers is crucial for safety and effective fire response.
