OSHA 30 Hour Construction Program Practice Test

What is a key characteristic of a limited access zone in masonry work?

1. It is only temporary

2. It is equal to the height of the wall plus 4 ft

3. It must be less than 10 ft wide

4. It allows unrestricted access

The correct answer is: It is equal to the height of the wall plus 4 ft

A key characteristic of a limited access zone in masonry work is that it must be equal to the height of the wall being constructed plus an additional 4 feet. This regulation ensures that the area surrounding the masonry work is adequately controlled to protect workers from falling materials and potential hazards from the work being done at elevated heights. The rationale behind this requirement is to establish a boundary where only authorized personnel may enter, which minimizes the risk of injury due to falling objects, equipment, or other hazards associated with masonry operations. This measure is critical for maintaining safety on construction sites, as it delineates a clearly defined area where additional caution is necessary due to the proximity to hazardous activities. Understanding this characteristic is vital for ensuring compliance with safety regulations and for the effective management of risk on construction sites.
