What is a significant safety recommendation regarding the movement of ladders?

The recommendation that a ladder must not be moved when someone is on it is vital for ensuring the safety of the person using the ladder. When an individual is on a ladder, their center of gravity is shifted, and moving the ladder can lead to instability, potentially causing the person to fall and sustain injuries.

By establishing this rule, it emphasizes the importance of maintaining a stable and secure ladder position. Ensuring that no one is on the ladder before moving it allows the individual to focus on safely navigating their work area without the added risk of losing balance or control.

While securing a ladder before anyone climbs is also crucial, this particular recommendation specifically addresses the scenario of safety during the ladder's use. This understanding is essential for anyone involved in roofing or similar trades where ladder safety is paramount.
