A construction worker is required to wear a personal fall arrest system while working on a roof. The lanyard being used is 6 feet long with a 3.5-foot deceleration distance. What is the minimum distance the anchor point must be below the roof edge to prevent the worker from hitting the ground on a 20-foot high building?
Correct Answer
C) 12 feet
Total fall distance = lanyard length (6') + deceleration distance (3.5') + safety factor (2.5') = 12 feet minimum clearance required below the working level.
Why This Is the Correct Answer
Total fall distance = lanyard length (6') + deceleration distance (3.5') + safety factor (2.5') = 12 feet minimum clearance required below the working level.
