Permanent, curved, spring-loaded metal devices that secure the tip of a roof ladder to a pitched roof are:

The answer B refers to roof hooks, which are essential tools used in firefighting when positioning a roof ladder on a pitched roof. Roof hooks are designed with permanent curved metal components that allow them to securely grip the roofing material. Their spring-loaded mechanism aids in maintaining tension and helps stabilize the ladder, which is especially important when accessing a roof during firefighting operations.

When a firefighter places a roof ladder against a pitched roof, the roof hooks anchor the ladder in place, minimizing the risk of slipping or falling. This secure attachment is critical for safety, as it allows firefighters to perform their tasks efficiently and safely while elevated. In addition, the design of these hooks ensures they can accommodate different types of roofing materials and slopes, making them versatile for various situations encountered during fire response.

Understanding the function and importance of roof hooks contributes to overall operational safety and effectiveness for firefighters during roof access maneuvers.
