What is the concept of protecting exposures in exterior operations?

Applying water to the main fire only.

Protecting exposures is not part of exterior operations.

Directing all water to the interior crew.

Applying water to nearby structures or materials at risk of ignition to prevent fire spread from the main fire.

Protecting exposures means using water on structures or materials nearby that could catch fire, to stop the fire from spreading beyond the main flames. In exterior operations, this tactic targets the heat, flames, and embers that can reach adjacent buildings, vehicles, or vegetation. By cooling these exposures and keeping them wet, you reduce the likelihood they will ignite, which helps keep the fire from growing and buys time for interior crews or for a safer overall shutdown. This approach is a deliberate part of exterior strategy because preventing spread to surroundings is just as important as forcing the main fire to a stop.

Choosing to apply water only to the main fire neglects the risk to nearby exposures, and saying protecting exposures isn’t part of exterior operations misses a key containment goal. Directing all water to interior crews focuses on inside attack, which isn’t the same exterior objective of protecting surroundings.
