question 4 of 27
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:

• For "Distance of rope the grabbing device descends until fully locked on a vertical lifeline, or sag in a horizontal lifeline": This directly relates to the distance involved in the fall and the lifeline's behavior, so it's a factor.
• For "Extra length of webbing released by a shock - absorbing lanyard, which can add 3 - 5 feet": The extra webbing length from the lanyard affects the total fall space needed.
• For "Extra amount of stretch when using a vertical lifeline": The stretch of the vertical lifeline contributes to the fall space calculation.
• "Whether a temporary or permanent anchorage point is used" is more about the type of anchorage rather than a direct factor in calculating the fall space needed.

Answer:

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
