NOTE The recommendations regarding situations where the mass could be more than 100 kg applies especially in the case of rescue, where there could be more than one person attached to the anchor system. However, during rescue, IRATA rope access technicians are required and trained to follow procedures which restrict the potential for dynamic loading of the anchor system.2.11.2.9 Wherever feasible, the two independent anchors – one for the working line and one for the safety line, and each with a static strength of 15 kN or more – should be linked together for added security. This link can be achieved, for example, by the use of a double figure-of-eight knot on the bight (also known as a bunny knot) or a combination of a figure-of-eight knot on the bight and an alpine butterfly knot, see Figure 2.6a.
