Non-load bearing skylights must be protected by which type of system?

Non-load bearing skylights are vulnerable points on a structure where a fall hazard may exist. Therefore, it is essential to install a protective system that can prevent accidents. A screen, cover, or railing system is specifically designed to safeguard non-load bearing skylights by preventing individuals from falling through them while still allowing for necessary light transmission.

The use of a screen or cover, for example, creates a physical barrier that can support incidental load without risking a fall. Additionally, a railing system provides a robust perimeter around the skylight, ensuring that workers do not approach hazardous edges. This proactive approach to safety aligns with the standards set by the U.S. Army Corps of Engineers in EM 385-1-1, which emphasizes the importance of preventing injuries through appropriate safety measures.

In contrast, guardrails are generally associated with edges of floors or platforms rather than skylights specifically, while safety nets serve to catch falls rather than prevent them in the first place. Architectural barriers are typically related to access and mobility, not fall protection. Thus, the most appropriate protective system for non-load bearing skylights is indeed a screen, cover, or railing system, ensuring a comprehensive safety measure is in place at these vulnerable locations.
