What is the recommended extension for ladders below rooflines?

The recommended extension for ladders below rooflines is one to three rungs below rooflines. This guideline is crucial for ensuring firefighter safety and operational effectiveness. When a ladder is extended to the appropriate height, having one to three rungs remaining below the roofline allows for safe access and egress for firefighters. This extension helps prevent individuals from accidentally slipping off the ladder when transitioning onto or off the roof, which can occur if a ladder is too high or just at the roof edge.

Additionally, this positioning provides a secure handhold for firefighters as they navigate onto the roof or descend from it, promoting stability and reducing the risk of falls. In situations where rapid exit or entry is necessary, this extension provides a margin of error that enhances safety during challenging conditions. Therefore, this practice reflects established safety protocols in firefighting operations.
