This article discusses how the number of roof anchor point depends on design, access needs, and safety rules, not a fixed formula.
Question: To comply with safety standards, is there a formula to determine the number of roof anchor points per square metre?
Answer: We usually engage a rope access contractor under a design and construct arrangement to determine the appropriate anchor layout.
Anchor spacing isn’t based on a simple square metre allocation. It depends on several factors, including roof layout, access requirements, and regulatory guidelines. In most cases, we engage a rope access contractor under a design and construct arrangement to determine the appropriate anchor layout.
It’s also important to distinguish between the two types of anchors: fall arrest and rope access. Fall arrest anchors may not meet the strength or configuration requirements for rope access anchors.
