On which type of fire is water an acceptable extinguishing agent?

  1. Electrical fires

  2. Gasoline fires

  3. Tire fires

  4. Kitchen fires

The correct answer is: Tire fires

Water is an acceptable extinguishing agent for tire fires because it can effectively cool down the burning material and reduce the temperature below the ignition point, thereby suppressing the fire. While tires can emit harmful smoke when burned, and water may not be the most effective solution in every circumstance, it can still be used in many situations involving tires to help control and extinguish the flames. In contrast, other options present scenarios where water is typically not appropriate. For example, using water on electrical fires can lead to the risk of electrocution, as water is a conductor of electricity. In the case of gasoline fires, water can spread the flammable liquid rather than extinguish the fire, as it does not effectively suppress the burning liquid. For kitchen fires, which can often involve grease, water may cause the grease to splatter and spread the flames, resulting in a more dangerous situation. This highlights why understanding the nature of the fire and the materials involved is crucial for choosing the right extinguishing agent.
