5.6 DUAL LEG SRL
With the Dual Leg Safewaze SRL mounted on the back of a Full Body Harness, the user can have continuous fall protection (100 % tie-off) while
ascending, descending, or moving laterally (See Figure 12)
.
With the lifeline leg of one SRL attached to an anchorage point, the worker can
move to a new location, attach the unused lifeline leg of the other SRL to another anchorage point, and then disconnect from the original anchorage
point (See Figure 12).
IMPORTANT:
Never connect more than one person at a time to the dual-leg system.
IMPORTANT:
Do not allow the lifelines to pass under arms or between legs.

Maximum Arresting Force
≤ 1,800 lbs. (8.0 kN)
Maximum Arrest Distance
24 in. (0.61 m)
6.2 MAXIMUM ARREST FORCE AND MAXIMUM ARREST DISTANCE
SRLs documented in this instruction manual meet the following Arrest Force and Arrest Distance maximums when tested in accordance with Section
4.2.1 of ANSI Z359.14. These calculations are based upon overhead anchorage of the SRL.
TABLE 10 - CLASS A
Average Arresting Force
≤ 900 lbs. (5.0kN)
Maximum Arresting Force
≤ 1,800 lbs. (8.0 kN)
Maximum Arrest Distance
54 in. (1.37 m)
TABLE 11 - CLASS B
5.5 ANCHORAGE
Select an anchorage location with minimal free fall and swing fall hazards (See Section 2.0). Select a rigid anchorage point capable of sustaining static
loads as defined in Section 2.0. Where anchoring overhead is not feasible, Safewaze SRLs may be secured to anchorage points below the level of the
user’s dorsal D-ring, but never below the user’s feet. NOTE: ANCHORAGE BELOW THE DORSAL D-RING WILL REQUIRE ADJUSTMENT OF THE
TOTAL FREE FALL AND MAXIMUM ARREST DISTANCE OF A FALL.
WARNING:
Never connect the snap hook of one SRL to the lifeline of another SRL or lanyard. Failure to comply with
this warning may result in equipment malfunction, serious injury or death.
