When using a safety lifeline, it's crucial to minimize free fall distance to prevent potential injuries 3, 5, 19. Position the tie-off point above the harness connection to avoid increasing the free fall distance 3, 5. Ensure there's enough clearance below to account for lanyard elongation and deceleration distance during a fall [1].

Regularly inspect the lifeline for defects like cuts, tears, abrasions, or damage from corrosives, and immediately remove any compromised components from service [2]. Protect lifelines from sharp edges to prevent cuts or chafing [3]. When using vertical lifelines, each worker must have a separate line to prevent multiple falls in case one worker falls 5, 7, 19.

For horizontal lifelines, be aware that the impact force on the lifeline increases as the sag angle decreases [4]. Ensure horizontal lifelines are designed by qualified persons and consider testing installed lifelines and anchors before use [4]. Locking snap hooks are essential to prevent accidental disengagement [5].

Always have a rescue plan in place to quickly assist a fallen worker 9, 10. Thorough employee training is vital for the correct selection, use, and inspection of personal fall arrest systems [2].
