2.11.3.1.17 On sloping surfaces such as rock slopes, or on pendulums, care should be taken to avoid anchor lines snagging, e.g. during any lateral movement to be followed by a further descent. If the rope becomes un-snagged during these manoeuvres, e.g. if the feature causing the anchor lines to snag fails or if the anchor lines slip off it, the rope access technician could fall as the rope is released and it reverts to being in a straight line with the anchor – see Figure 2.10.2.11.3.1.18 The use of anchor lines to haul equipment should be avoided or great care taken to avoid mid-rope snagging if they are lowered again for further use. Dangerous snagging may be prevented by tying equipment in the centre of the rope and using the lower half as a back-rope to keep the equipment away from the surface of the slope or structure.
