Which method is NOT typically a part of direct attack strategies?

In the context of firefighting strategies, direct attack methods involve engaging the fire directly to extinguish it as quickly as possible. This typically includes applying water or other suppressants directly onto the flames, utilizing foam to smother fires, and employing techniques such as cold trail methods to cool hot areas. These methods focus on immediate suppression and control of the fire itself.

Creating a perimeter, on the other hand, is more aligned with indirect attack strategies. This involves setting up a boundary to contain the fire and prevent it from spreading, rather than directly attacking the flames. An indirect approach may be necessary in situations where the fire is too dangerous to confront head-on or when resources are limited. While all strategies have their place in the broader fire suppression efforts, creating a perimeter is not a direct attack method because it focuses on containment rather than direct extinguishment of the fire.
