OSHA National Association of State Contractors Licensing Agencies (NASCLA) Practice Exam

The correct height for scaffold handrails is between 36 and 45 inches. This standard range is established to ensure safety for workers on scaffolds, minimizing the risk of falls. Handrails that are placed within this height range provide adequate support and help workers maintain balance while they perform their tasks at elevated heights.

In addition, this height range is designed to fit the majority of workers, accommodating various body sizes and ensuring that the rails are effective in preventing falls. Furthermore, maintaining this standard height aligns with OSHA regulations, which emphasize the importance of proper safety measures on construction sites.

While there might be other height standards related to different types of safety barriers, in the context of scaffold handrails, the specified range of 36 to 45 inches is critical for promoting a safe work environment.
