When using a combination attack, what is the first action that should be taken concerning the ceiling?

Starting with penciling at the ceiling is essential when using a combination attack because it allows firefighters to assess the conditions above them before fully committing to the next steps in the firefighting process. Penciling involves directing a stream of water towards the upper parts of the fire area, specifically targeting the ceiling and upper walls. This helps in cooling the hot gases that accumulate in those regions, which can prevent flashover and improve the safety of the firefighting team.

By beginning with this approach, firefighters can also gauge the fire’s intensity and the potential for extension, providing crucial information that influences subsequent tactical decisions. This initial action is vital in a combination attack, where both direct and indirect methods are employed to suppress a fire effectively. Furthermore, it creates an opportunity to reduce heat and improve visibility within the space, benefiting both the firefighters and any potential victims who may need rescue.
