which of the following are factors to take into consideration when calculating the amount of fall space needed?
select all that apply

• whether a temporary or permanent anchorage point is used
• distance of rope the grabbing device descends until fully locked on a vertical lifeline, or sag in a horizontal lifeline
• extra length of webbing released by a shock - absorbing lanyard, which can add 3 - 5 feet
• extra amount of stretch when using a vertical lifeline

Explanation:

To determine factors for fall space calculation:

• The type of anchorage point (temporary/permanent) affects fall space as different anchorages have different stability and movement characteristics.
• The distance the grabbing device descends (vertical lifeline) or sag (horizontal lifeline) directly contributes to the required fall space as it's part of the total distance an individual could fall before the system stops them.
• The extra length from a shock - absorbing lanyard (3 - 5 feet) is an additional distance that must be accounted for in fall space.
• The extra stretch in a vertical lifeline also adds to the total fall distance as the lifeline will stretch under load, increasing the fall space needed.

Answer:

A. Whether a temporary or permanent anchorage point is used
B. Distance of rope the grabbing device descends until fully locked on a vertical lifeline, or sag in a horizontal lifeline
C. Extra length of webbing released by a shock - absorbing lanyard, which can add 3 - 5 feet
D. Extra amount of stretch when using a vertical lifeline
