Fall Clearance Formula Guide

Clearance = LL + DD + HS + SF + WH
LL
Lanyard Length (free fall distance)
DD
Deceleration Distance (energy absorber)
HS
Harness Stretch (webbing elasticity)
SF
Safety Factor (additional buffer)
WH
Worker Height (feet to D-ring)

Safety Guidelines:

  • < 2.0m → Insufficient clearance
  • 2.0 - 3.0m → Adequate clearance
  • > 3.0m → Safe margin
Always verify with manufacturer specifications. Minimum recommended clearance is 2.0 meters (6.5 feet).
