IMPORTANT NOTES:
Self-retracting lifelines must be anchored
overhead to ensure the accuracy of the fall
clearance calculation and related information.
It is important to understand that other fac-
tors, such as whether the user is performing
work in a standing, crouched or lying down
position and/or whether the user is working
directly below the anchor point or at an angle,
can affect fall distance when using a retract-
able device.
The self-retracting lifeline fall clearance cal-
culation assumes the user is standing. If the
user will be performing work in a crouched or
kneeling position, an additional 3 ft. (0.9m) of
fall clearance is required (see Fig. 8b). If the
user will be performing work in a lying down
position, an additional 5 ft. (1.5m) of fall clear-
ance is required.
The self-retracting lifeline fall clearance cal-
culation also assumes the user is working
directly below the anchor point, minimizing
any possibility for a swing fall. In a swing fall
situation, the total fall distance will be greater
than if the user were working directly below
the anchor point (see Fig. 8c). In some ap-
plications, it may not be possible to work di-
rectly below the anchor point. In such a case,
the worker must increase the fall clearance
distance to account for the swing fall factor.
In any case, the worker must not be exposed
to a potential swing fall where contact with
another object may occur (see Fig. 8d).
The maximum arrest distance [free fall (FF)
+ deceleration (D)] varies by retractable. Al-
ways refer to the labels on the specific unit to
determine the maximum arrest distance.

*This chart shows general minimum fall clearances required. An exact calculation, based on the SRL/Fall Limiter to be
used and an assessment of the work site and conditions that may affect the worker's fall clearance, must be performed.

If a self-retracting lifeline with a maximum
arrest distance of less than 54 in. (1.4m) has
been approved for (by Honeywell) and is be-
ing used in a non-overhead application, the
maximum arrest distance allowed per stan-
dards--54 in. (1.4m)--must be used when cal-
culating fall clearance distance.
If a self-retracting lifeline with a maximum
arrest distance of less than 54 in. (1.4m) has
been approved for (by Honeywell) and is be-
ing used by a worker weighing between 310
lbs. (140.6kg) and 400 lbs. (181.4kg), the
maximum arrest distance allowed per stan-
dards--54 in. (1.4m)--must be used when cal-
culating fall clearance distance.
