Beyond the manufacturer's requirements: the anchorage and its structure must sustain the Table 3.1 ultimate load in the direction of loading, increased by 6 kN (to 21 kN) if two people share it, with no more than two people on one point, and preferably 15 kN for single-person points; an engineer must assess the structure and anchorages, except where a height safety supervisor can plainly see the arrangement is structurally adequate (for example a rated sling round a solid permanent structure), and wherever there is doubt an engineer must assess and certify in writing that worst-case load combinations are contained; free fall-arrest anchorages are required where a fall over 600 mm is possible and limited free fall-arrest anchorages only where it is not; signage per clause 3.2.5 must be provided; anchorages must be sited with enough fall distance to avoid striking lower obstructions (machinery, open windows, doors or panels), or else Section 7 applies; users must be able to connect before moving into a fall-risk position unless already protected by another system; deterioration from chemicals, corrosion or weather should inform material and design; and drilled-in friction or glued anchorages must be placed so shear load is at least twice tension (for collared eyebolts, a pull no more than 20 degrees to the surface).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
