6.0 Calculating Fall Clearance Distance

It is essential to understand how to calculate the fall clearance distance required

*This chart shows general minimum fall clearances required. An exact calculation, based on the SRL to be used and an
assessment of the work site and conditions that may affect the worker's fall clearance, must be performed.
IMPORTANT NOTES:
Self-retracting lifeines 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.
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.
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
another object may occur.
