If applicable : using the tagline, draw the SRL snap hook down, disconnect the
tagline, and attach it to the full-body harness.
WARNING: Coil and secure tagline to prevent interference or entanglement with
workers, equipment or machinery.
USE
Once attached, the worker may move about therecommended work zone.
Upon completion of work, detach SRL snap hook; if applicable, reconnect
tagline clip to SRL snap hook before allowing lifeline to retract back into the SRL
housing. Always retract lifeline in a controlled manner.
6- CALCULATING FALL CLEARANCE DISTANCE
It is essential to understand how to calculate the fall clearance distance required
for each work application to avoid contact with a lower level.
The basic calculation and diagrams on the following page may be used to
determine Required Fall Clearance when using a self-retracting lifeline in an
overhead application.
Self-Retracting Lifeline Fall Clearance Calculation
[Calculation taken from work level]
Maximum Arrest Distance
+ (Non-Standing Work Position Factor)
+ (Swing Fall Factor)
+ 3 ft. (1m) Safety Factor
= Required Fall Clearance
CAUTION: Read all notes and re- fer to all self-retracting lifeline fall clearance
diagrams to determine exact required fall clearance for your application.

*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. Any value indicated
in the above table is applicable for a user weight from 100 up to 140kg.
