What is a consideration when rescuing victims off a parapet-style roof?

When rescuing victims off a parapet-style roof, resting the roof ladder against the aerial ladder is essential for ensuring stability and safety during the rescue operation. Parapet roofs often present challenges due to their design, which can make it difficult for rescuers to reach victims or maneuver effectively. By resting the roof ladder against the aerial ladder, it creates a secure and calibrated connection, allowing rescuers to safely navigate the distance between the aerial device and the roof surface. This method helps mitigate the risks associated with height and unstable footing, making the rescue operation more efficient and secure.

In contrast, considerations like using a rescue basket instead of a ladder may be impractical or unnecessary for specific rescues, particularly if the victims are already near the edge of the roof. While the request for additional manpower is critical for many rescue operations, it doesn't specifically address the unique challenges of parapet roofs. Also, limiting the use of aerial devices solely to severe emergencies is not a sound approach, as effective rescue often requires their deployment in various situations, not just in dire circumstances.
