The height of handrails shall not be more than ________ or less than ________.

The height of handrails is specified in safety regulations to ensure the effectiveness and safety of fall protection in various environments. According to the U.S. Army Corps of Engineers (USACE) EM 385-1-1 guidelines, handrails must be designed to be both functional and safe for the users.

In this context, the correct answer provides the specifications that fall within the recommended standard height range for handrails, which plays a crucial role in preventing falls and providing support to individuals traversing stairs, ramps, or elevated walkways. The specified range not only accommodates a variety of users, including those who may be taller or shorter, but also aligns with general best practices found in broader safety regulations.

This standard height also considers ergonomics, ensuring that handrails are positioned effectively for an average adult's grip while minimizing the risk of accidents. By adhering to this requirement, facilities can enhance safety and compliance with federal guidelines, thus protecting workers and the public.
