Final answer:
The minimum height and width requirements for guarding wall openings depend on the anticipated drop distance.
Step-by-step explanation:
The Height and Width Requirements for Guarding Wall Openings
In order to ensure safety, wall openings that could potentially lead to falls must meet certain height and width requirements. According to the given information, the minimum height of these wall openings should be 15 times the anticipated drop distance. As for the width, the rule of thumb is to have a width of at least 8 times the anticipated drop distance.
For example, if persons could fall with a drop of more than 10 feet, then the minimum height requirement would be 150 feet (15 x 10) and the minimum width requirement would be 80 feet (8 x 10).
