The requirement for a masonry-project "limited access zone" being equal to the height of the wall to be reconstructed plus four feet is rooted in safety protocols designed to protect workers from potential hazards associated with masonry operations, particularly during reconstruction activities.

This specific height ensures that the area surrounding the masonry work is sufficiently clear of potential falling debris, which is a significant risk when working at heights. By establishing a limited access zone that extends to the height of the wall plus an additional four feet, regulations aim to create a safer working environment and minimize the chances of accidents caused by materials or equipment falling from the wall or workspace.

The focus on an adequate safety buffer aligns with general construction safety practices, which prioritize preventing injuries due to falling objects. By adhering to these guidelines, workers and bystanders can maintain a safer distance from the reconstruction activity, thus contributing positively to the overall safety management of the construction site.
