An energy absorber comprises a base having a weakened portion, a mounting aperture, and a connecting aperture. An energy absorber assembly includes the energy absorber, an anchor member extending through the connecting aperture, a mounting bracket including an aperture, and a fastener extending through the aperture of the mounting bracket and the mounting aperture of the energy absorber. 1. An energy absorber , comprising:a base;a weakened portion in the base, the weakened portion being arranged in a spiral configuration;a mounting aperture in the base proximate an outer portion of the spiral configuration; anda connecting aperture in the base proximate a center of the spiral configuration.2. The energy absorber of claim 1 , wherein the base is a disk member.3. The energy absorber of claim 2 , wherein the disk member is round.4. The energy absorber of claim 1 , wherein the weakened portion includes a plurality of alternating connected portions and cuts extending through the base.5. The energy absorber of claim 4 , wherein the cuts are elongated.6. The energy absorber of claim 1 , wherein the weakened portion forms an elongating portion having an intermediate portion interconnecting a distal end and a proximal end claim 1 , the distal end being positioned proximate the center of the spiral configuration and the proximal end being positioned proximate the outer portion of the spiral configuration claim 1 , the distal end and the intermediate portion being configured to separation from the base and deform to absorb energy.7. The energy absorber of claim 1 , further comprising:an anchor member extending through the connecting aperture;a lifeline operatively connected to the anchor member;an anchorage structure; anda mounting bracket interconnecting the base and the anchorage structure.8. The energy absorber of claim 7 , wherein the anchorage structure is a stanchion.9. The energy absorber of claim 1 , further comprising:an anchor member extending through the connecting ...
