Before climbing an extension ladder, it is crucial that the pawls are locked. The pawls are safety mechanisms that engage to prevent the fly section of the ladder from inadvertently sliding down while someone is on it. Ensuring that the pawls are locked contributes significantly to the safety of the firefighter, as it provides stability and prevents potential accidents during ascent or descent.

Checking that the pawls are locked is standard practice because it ensures that the ladder will remain at the desired height and that the structure of the ladder is secure while being used. This is an essential step that helps prevent injuries that could occur if the ladder were to collapse under weight due to unsecured components. Safety protocols prioritize ensuring all locking mechanisms are engaged to provide maximum integrity to the ladder prior to climbing.
