LIFELINE DEPLOYMENT LIMITER FOR SELF-RETRACTING LIFELINE
A system is disclosed. The system comprises a self-retracting lifeline having at least one sensor configured to measure distance parameter with respect to a position of the self-retracting lifeline. A device coupled operationally with the self-retracting lifeline, having a processor and a memory configured to store instructions which when executed by the processor causes the processor to receive the distance parameter with respect to the position of the self-retracting lifeline; determine a lifeline extension limit based on the distance parameter; and execute one or more operations upon reaching the lifeline extension limit, for a safety event. The one or more operations comprise at least one of applying a brake to the self-retracting lifeline and/or triggering an alarm.
