3 Ways to minimize the arresting force:
• (a) Minimize the fall distance
• (b) Minimize the working weight
• (c) Maximize the Stopping Distance

As the free fall distance increases, the
arresting force increases:
• Use a shorter lanyard
• Anchor higher up
• Use a retractable (SRL)

arresting forces also increase:
• Carry less tools
• Rope and bucket or mechanical aid
