Can you use a 50' SRL of a 20' fall?

While my knowledge base doesn't contain specific documentation on the use of a 50-foot Self-Retracting Lifeline (SRL) in a 20-foot fall scenario, I can provide general safety guidance based on industry best practices and general fall protection principles.

When using a Self-Retracting Lifeline (SRL), it's crucial to calculate the total fall clearance distance to prevent 'bottoming out'.

To determine the total fall clearance distance, consider these elements:

• Length of the lanyard
• Length of the energy absorber when deployed
• Length of the harness and other equipment when stretched
• Location and strength of the anchor point
• Worker's height
• Vertical and horizontal clearances
• Potential for pendulum or swing falls
• A safety factor distance

To prevent bottoming out, the fall clearance distance must be longer than the distance the worker could fall before being stopped by the fall arrest system.

Other key considerations:

• Suitability of Anchor Points: Ensure anchor points are appropriate in terms of strength, stability, and location for the work being done.
• Swing-Fall Distance: Consider the swing-fall distance and free-fall distance when selecting the location of the anchor. Try to select an anchor point directly above the worker to reduce the swing distance if a fall occurs.
• Competent Person Inspection: Visually inspect anchors for damage, corrosion, and suitability before connecting the fall protection equipment.

Remember to develop a comprehensive fall protection plan that includes rescue procedures, proper training, and regular equipment inspections.
