How high should the top of a guard rail be?

The top of a guard rail should be set at a height of 42 inches. This standard height is established to ensure maximum safety in environments where falling hazards are present. By setting the guard rail at this specific height, it provides an adequate barrier that helps prevent falls from elevated surfaces, effectively guiding individuals and maintaining safety standards.

Choosing 42 inches as the height of the guard rail accounts for the average height of individuals and is designed to be protective without being overly obstructive. This measurement aligns with safety regulations, which are informed by research and practical experience in construction and safety protocols. Additionally, a guard rail set at this height is easier to see and navigate around for individuals working near edges or elevated areas.
