Which of the following is a reason to consider using PPV after vertical ventilation?

Explanation:
PPV after vertical ventilation is used to create a flow that pushes remaining smoke and hot gases toward the exterior exhaust, clearing the structure and improving visibility and conditions for interior crews. This helps interior teams see better, move more safely, and conduct searches more effectively. The other options aren’t aligned with PPV’s purpose: cooling exterior walls with water doesn’t involve ventilation flow, increasing interior temperature worsens conditions, and delaying search isn’t a goal.
