Which technique is appropriate when working with extension ladders?

Grasping the extension ladder beams when extending or retracting is important for maintaining control and stability during the operation of the ladder. This technique allows firefighters to manage the extension process safely and effectively, minimizing the risk of losing balance or causing the ladder to become unstable. By holding the beams, the firefighter can apply the necessary force to extend or retract the ladder while keeping their body positioned in a stable manner.

This technique also helps to provide a safer grip that reduces the likelihood of slipping or dropping the ladder, which can occur if one were to use less stable handholds. Ensuring that hands are securely positioned on the beams allows for better control, particularly when maneuvering in different environmental conditions, such as on uneven ground or in windy weather.

In contrast, the other techniques listed are less safe due to increased risks of instability, accidents, or improper handling of the equipment.
