What is the minimum requirement for establishing a limited access zone during wall construction?

The minimum requirement for establishing a limited access zone during wall construction is based on the height of the wall plus a specified distance for safety. The correct approach requires that this limited access zone be established at a distance equal to the height of the wall plus four feet. This is crucial for safety as it helps to protect workers from falling materials and debris during the construction process. This distance allows for a buffer zone that accounts for the potential risk of materials dislodging as walls are erected.

Using the height of the wall plus four feet as a standard ensures that all personnel are kept at a safe distance from the hazards presented by the working conditions surrounding wall construction. This requirement is grounded in safety regulations designed to minimize the risk of accidents and injuries on construction sites, promoting a safer working environment.
