Which of the following best describes indirect attack in fire-fighting strategy?

Indirect attack in firefighting strategy refers to the method of applying water to the hot gases and the environment above the fire rather than directly onto the flames themselves. This approach is effective because it cools the upper layer of hot gases, which can displace the heat and smoke, thereby reducing flame intensity and creating a safer environment for firefighters to operate. By targeting the superheated gases, this technique can help to prevent the fire from spreading and allow for a more controlled and strategic approach to extinguishing the fire.

This method often precedes a direct attack, as it can reduce the thermal layer of heat that would otherwise endanger personnel moving closer to the actual fire. Indirect attack is particularly useful in structural firefighting situations where direct application might be too hazardous due to extensive heat and smoke.
