Final answer:
It is incorrect to move the scaffold while someone is on it due to safety concerns, particularly on an inclined surface. The correct procedure is to have the person descend before moving the scaffold.
Step-by-step explanation:
The procedure of instructing a worker to move the scaffold while someone is still on it is incorrect. The primary reason is that any movement could cause the scaffold to become unstable or tip over, especially since it's on a surface with a five-degree incline. Even with the scaffold's rubber wheels designed for mobility, safety protocols usually require that no one should be on the scaffold while it is being moved to prevent accidents and falls. The correct action is for the person on the scaffold to descend and then relocate the scaffold from the ground, ensuring that the wheels are locked before getting back on.
