Question

11. A worker is using pfas and falls a total of 12 feet total distance from the edge and contacts the floor below. His pfas consist of a 6 foot shock absorbing lanyard attached to an anchor 3 feet from the leading edge. What is the violation?

12. From the above scenario: a worker working near a 12 foot leading edge. How high would a horizontal lifeline be in order to prevent him from striking the floor below? Also, how far back would an anchor have to be on the floor to keep the worker from hitting the floor? Devise one other method for protecting the worker---you may set up the scenario in any manner you wish.

13. How often must a pfas be inspected?

Explanation / Answer

11. An allocation for the height of the worker (appr. 6 ft.) was not made. Also, deceleration distance of 3.5 ft was also not allocated.

12. A horizontal lifeline should be at a minimum of 18.5 ft. in order to prevent him from striking the floor below. The anchor must be above head height to prevent striking. Another way to protect the worker is the usage of safety nets.

13. The pfas must be inspected at least once before the beginning of a shift of typical 8 hours.
