A worker is tied off using a 6-foot shock-absorbing lanyard to an overhead anchor point. The shock absorber can deploy a maximum of 3.5 feet. The worker is 6 feet tall. A safety factor of 3 feet is required. Calculate the total required fall clearance from the anchor point.

A worker on a roof edge must tie off. The only available anchor point is at their feet (deck level). They use a standard 6-foot lanyard. If they fall over the edge, calculate their free fall distance. Does this comply with safety standards?

A worker ties off to an anchor point located 15 feet horizontally away from their work zone on an open edge. They are using a 20-foot Self-Retracting Lifeline (SRL). They slip over the edge. What is the primary physical hazard they face?

A steel erector falls and is successfully saved by their harness and double-lanyard system. They are suspended in mid-air, uninjured. However, the rescue team takes 45 minutes to retrieve them. During this time, the worker loses consciousness and later dies in the hospital.
