What is the maximum spacing allowed between permanent fall arrest systems on the roof?

The maximum spacing allowed between permanent fall arrest systems on the roof is critical for ensuring the safety of workers who perform tasks at heights. A spacing of 10 feet is suitable because it allows for adequate coverage and ensures that workers can easily access the fall protection system without being too far away from the safety anchors. This distance helps minimize the risk of falls by providing more frequent anchor points, which can be reached quickly and efficiently.

Effective fall arrest systems must be strategically placed to prevent workers from reaching the edge of the roof or other hazards while they are working. If the spacing were greater, such as 15 feet or more, there would be an increased risk of falls and potential injury, as workers might not have access to a secure anchoring point when needed. In addition, spacing the systems too closely at 5 feet could lead to complications such as entanglement or reduced mobility, making it difficult for workers to maneuver safely on the roof.

Thus, the 10 feet spacing reflects a balance between safety, accessibility, and practicality in fall protection planning on roofs.
