How to Use This Calculator
  1. Enter working height (ft or m) and select fall protection system type (guardrail, PFAS, safety net).
  2. Enter worker weight (lbs or kg) and lanyard length (ft) for PFAS calculations.
  3. Read minimum fall clearance distance (ft) required below the work surface.
  4. Verify anchor point strength meets OSHA minimum 5,000 lbs per attached worker.
  5. Check that total fall distance (free fall + deceleration + D-ring + harness stretch) clears any obstructions.
