5.4.4 FT-X with a Non-Overhead Anchorage Leading Edge Anchorage Application
[310 to 420 lbs. (141 to 191 kg) user]
The leading edge/below D-ring condition minimum required fall clearance (MRFC) is calculated using
five metrics, measured from the walking-working surface: SRD Deceleration Distance, D-Ring Shift and
Harness Stretch [1 ft (0.3m)], Safety Factor [1.5 ft (0.5m)], Dorsal D-ring Height [5 ft (1.5m)], and Swing
Fall. Dorsal D-ring height is added to account for the below D-ring tie-off compared to the overhead
condition.

6.0 Maintenance, Service, and Storage
6.1 Maintenance:
Ensure the SRL is kept free of excess paint, grease, dirt or other contaminants as this may cause
the lifeline or retracting mechanism to malfunction. Ensure no debris enters the housing. Clean the
exterior of the unit as required with a detergent/water solution. Do not allow water or other corrosion

the SRD, and the SRD is anchored between the Fall Clearance From

user's Dorsal D-Ring or up to 4.0 ft (1.2 m) above
the D-Ring. Minimum required fall clearance is 11
feet (3.4 m) including swing fall.
Example 2:
If the user needs to work 4 feet (1.2 m) away from
the SRD along the edge, and the SRD is anchored
at foot level, the minimum required fall clearance
is 22 feet (6.7 m) including swing fall.
