Final answer:
Water should not be used to put out gasoline fires, tire fires, or electrical fires due to risks such as spreading the fire further, reignition, and electrical shock. Special extinguishers designed for the specific types of fires, such as dry chemical extinguishers for gasoline fires, foam for tire fires, and Class C extinguishers for electrical fires, should be used instead. The correct answer is none of the above.
Step-by-step explanation:
- Gasoline fires.
- Tire fires.
- Electrical fires.
However, water should not be used to put out gasoline fires, tire fires, or electrical fires. Each one of these fires requires a specific type of extinguisher due to the nature of the material or element involved in the fire.
For instance, gasoline fires should not be extinguished with water because gasoline is less dense than water and would float, potentially spreading the fire further. Water can also cause splashing, which can spread the fire even more. Special chemical extinguishers, such as dry chemical extinguishers, are designed to handle flammable liquid fires like gasoline.
Similarly, tire fires are difficult to extinguish with water due to the high heat and the potential for re-ignition. Foam is typically used to suffocate the fire and prevent oxygen from continuing to feed it. This can be followed by water cooling, but generally direct water application is not recommended initially.
Electrical fires involve the risk of electrical shock if water is used as an extinguishing agent. Therefore, it is crucial to use a Class C fire extinguisher in the United States, which is non-conductive and safe for use on electrical fires.
