Appendix B—Calculating fall clearance distance using a shock-absorbing lanyard and D-ring anchorage connector—Nonmandatory guidelines for complying with WAC 296-155-24613 (1)(d).

Do the following to calculate the fall clearance distance using a shock-absorbing lanyard and D-ring anchorage connector:

• First, add the length of the shock-absorbing lanyard (6 feet) to the maximum elongation of the shock absorber during deceleration (3 1/2 feet) to the average height of a worker (6 feet).

• Then, add a safety factor of 3 feet to allow for the possibility of an improperly fit full body harness, a taller than average worker and/or a miscalculation of distance.

• The suggested safe fall clearance distance for this example is 18 1/2 feet.
