How do you put out a Class A fire?

Water
Gas
Fabric
All of the above

The correct answer is: Water

Using water is the correct method to extinguish a Class A fire, which primarily involves ordinary combustible materials such as wood, paper, and textiles. Water is effective in cooling the burning material, thereby reducing the temperature below the ignition point and putting out the fire. Fires classified as Class A include those that involve materials found in many common settings, making water a readily available and effective extinguishing agent. It absorbs heat and helps to smother the flames, ultimately stopping the fire's progress. The other options are not suitable for Class A fires. Gas can actually exacerbate a fire, increasing the intensity and spreading the flames. Fabric, depending on its composition and condition, may also ignite or not be effective in smothering flames. Therefore, the use of water is the safest and most effective method for addressing this type of fire.
