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 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 retractable 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. 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. 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.
The maximum arrest distance (free fall + deceleration) varies by retractable.
Always refer to the labels on the specific unit to determine the maximum arrest
distance.
