Permanent fall arrest/restraint anchorage devices can replace guards if they comply with which of the following?

Permanent fall arrest/restraint anchorage devices can indeed replace guards if they comply with specific industry standards and placement guidelines. The inclusion of all mentioned conditions in the correct choice reflects a comprehensive understanding of fall protection requirements.

Firstly, compliance with ANSI/ASSE Z 359.1 is crucial because this standard outlines the requirements for the performance, design, testing, and use of fall protection systems. Adhering to this standard ensures that the anchorage points for fall arrest systems are designed to safely support the expected loads and that the system overall is effectively preventing falls.

Additionally, having anchorage devices placed at a maximum of 10 feet on center along hip and ridge lines contributes to the effectiveness of the fall protection system, ensuring that workers have access to fall protection that is readily available and strategically positioned to minimize risk.

Moreover, requiring anchorage devices to be placed a minimum of 10 feet from the roof edge is equally important. This distance provides a buffer zone that reduces the likelihood of a worker inadvertently falling over the edge, thereby enhancing overall safety on working elevations.

By satisfying all these criteria—compliance with standards and appropriate placement guidelines—permanent fall arrest/restraint anchorage devices can appropriately take the place of guardrails, which are typically used to prevent
