What is the first step in relocating an articulated ladder while in use?

The process of relocating an articulated ladder while it is in use requires prioritizing safety and stability. The correct first step is to first descend, then relocate the ladder. This is essential because remaining on the ladder while attempting to move it increases the risk of losing balance and experiencing a fall.

Descending first allows the user to safely stabilize themselves on solid ground, where they can then properly assess and execute the relocation of the ladder. Movement while on a ladder can compromise safety, making it imperative to ensure that the individual is completely off the ladder before making any adjustments to its position.

The other options do not prioritize safety in the same manner. Ascending to the highest rung while relocating poses significant risks, as does adjusting the angle or stabilizing the base without first being on the ground. Each of these actions could lead to instability and increase the likelihood of accidents.
