Question: 1 / 400

Which of the following should you use to extinguish a tire fire?

Foam extinguisher

Water

Using water to extinguish a tire fire is not advisable, as tires are made of rubber and often contain oils, which can cause the fire to flare up. The best method to extinguish a tire fire involves using options that can smother the flames or absorb the heat, but in this context, water is not the correct answer.

The proper approach to managing a tire fire typically involves utilizing a foam extinguisher or sand. A foam extinguisher works well by smothering the fire and cutting off the oxygen supply. Sand can also be effective as it helps to suffocate the flames. Therefore, while water might seem like a straightforward option, it is not effective and not recommended for tire fires.

In summary, while the notion of using water to fight a fire is common, when it comes to tire fires, specific methods that can efficiently smother and control the fire, such as foam extinguishers or sand, are the appropriate choices.
