Take into consideration the risks of injury and check before using a retractor that there is
the minimum clearance below the user's feet to avoid any collision with the structure or the
ground in a fall. Refer to your type of use to determine the applicable value (H), including a
safety distance of 1 meter.
IMPORTANT NOTES:
Self-retracting lifelines must be anchored overhead to ensure the accuracy of the fall clear-
ance calculation and related information.
It is important to understand that other factors, 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 calculation 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 Diagram 2). If the user will be performing work in a lying down
position, an additional 5 ft. (1.5m) of fall clearance is required.
The self-retracting lifeline fall clearance calculation 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 Diagram 3). In some applications, it may not be possible to work directly 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 Diagram 4).
The maximum arrest distance [free fall (FF) + deceleration (D)] varies by retractable. Always refer
to the labels on the specific unit to determine the maximum arrest distance.
