Retractable lifeline apparatus and method of using the same

A lifeline apparatus comprising:

• a housing defining an interior portion configured for storing at least a portion of a retractable lifeline therein;
• a spool lock assembly selectively configurable between a locked configuration and an unlocked configuration to facilitate a selective deployment of at least a portion of the retractable lifeline from within the housing, the spool lock assembly comprising:
• a latch plate configurable between a nominal position and an actuated position based at least in part on a user interaction with at least a portion of the latch plate;
• a lock arm at least partially engaged with the latch plate and configured for arrangement between an engaged position and a disengaged position based at least in part on a position of the latch plate, wherein the engaged position of the lock arm is defined by the lock arm being positioned to prevent the selective deployment of the lifeline from within the housing by restricting rotation of one or more components operatively connected to the at least a portion of the retractable lifeline;
• wherein the configuration of the spool lock assembly between the locked configuration and the unlocked configuration is defined at least in part by the position of the latch plate between the nominal position and the actuated position.
