6.0 Calculating Fall Clearance Distance
It is essential to understand how to calculate the fall clearance distance for each work
application to avoid contact with a lower level. Use the following calculation to determine
Required Fall Clearance.

*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.
IMPORTANT NOTES:
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 work
ing directly below the anchor point or at an angle, can affect fall distance when using a
retractable device.
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.
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 ac
swing fall where contact with another object may occur.
