A ratcheting anchorage device for use with a lifeline when performing tasks on a surface includes an anchorage member proximate the surface, a support member , a ratcheting device, an elongate member, and a connecting member. The support member is configured and arranged to be supported by the surface proximate the anchorage member. The ratcheting device is operatively connected to the support member . The elongate member has a first end and a second end. The first end is operative ly connected to the ratcheting device, and the second end is operatively connected to the connecting member, which is configured and arranged to engage the anchorage member. The ratcheting device is configured and arranged to ratchet the elongate member so that the elongate member becomes taut when the connecting member engages the anchorag e member thereby securing the support member to the anchorage member.
