What is the minimum required height for guards?

The minimum required height for guards is set at 42 inches. This standard is based on safety regulations designed to prevent falls from elevated surfaces, ensuring that guards are tall enough to effectively block individuals from slipping over the edge. By establishing a guard height of 42 inches, building codes aim to provide a level of protection that is appropriate for most situations, such as around stairways, balconies, and other elevated areas.

This height requirement is also informed by best practices and studies which show that a guard at this height offers a balance of safety while considering visibility and usability for individuals using these spaces. Lower heights may not provide adequate protection, while excessively high guards could obstruct views or create other safety hazards. The specified height is a critical component of safety design in construction and building maintenance.
