When positioning ladder pipes during defensive operations, with what feature should the ladders’ turntable be aligned?

In defensive operations, positioning ladder pipes effectively is crucial for maximizing operational efficiency and safety. Aligning the ladder's turntable with the corner of the building is optimal because it allows for better access to the building's exterior while providing a wider range of coverage for water application. This alignment gives operators the ability to direct the water stream onto the most affected areas of the structure while ensuring that the ladder can maintain stability and support the nozzle team.

Furthermore, positioning the turntable at the building's corner facilitates setup in tight spaces where other positions may limit maneuverability or accessibility. It also enhances visibility for the firefighters operating the ladder at various angles and provides a strategic advantage in battling the fire from multiple sides of the structure, especially if the fire is spreading.

Ensuring the ladder pipes are accessible and effectively covering potential fire spread areas is key in a defensive firefighting strategy, and aligning with the building corner achieves this aim.
