Accepted Answer

Adjustable tower scaffolding has a winch mechanism that can raise the working platform as work progresses, allowing the worker to maintain a comfortable working height.

Question 10

Safety lanes should be established where the MCWP is to be erected.

Accepted Answer

Safety lanes should always be established where the MCWP (Mast Climbing Work Platform) is to be erected to ensure the safety of the workers and equipment. These lanes provide a clear space for the movement of personnel, materials, and equipment, reducing the risk of accidents and injuries. Therefore, it is essential to follow this safety procedure on job sites.
