 Anchors used for lifeline anchorages are designed for force per connecting user, and the standard permits an anchor to deform in order to absorb energy (adhesive anchors have higher design requirements because of aging loss).The rope can be lifeline rope, which stretches to lengthen the fall distance as it absorbes energy; or static rope, which does not stretch and thus limits the fall distance, but requires the fall energy be absorbed in other devices.It is essential that the PPE be rated for Fall Arrest and PPE used with static line include an energy absorber.
