4 Components of a Personal Fall Arrest System • Body Support • Body Belts • Full Body Harness • Connectors • Lanyards • Self Retracting Lifelines • Vertical and Horizontal Systems • Anchorage • Engineered • Non Engineered • Rescue
OSHA 1926.502 (d) (16) (ii): Personal fall arrest systems shall limit the maximum arresting force on an employee to 1,800 pounds (8 kN) when used with a body harness. ANSI Fall Arrest (always must have) Dorsal D-Ring Full Body Harness

Lanyards Many different types of lanyards Needs to be able to reduce energy from 5000 lbs force to… 1800 lbs for OSHA ANSI 900 lbs or less……
Shock Absorbing Lanyards Always connect the shock pack to the Dorsal D-ring Make sure you are not exceeding the weight limit of the lanyard Never connect two lanyards together 100% Tie-Off
General Rule: “You need 12.5 ft of clearance with a 6 ft lanyard” 6.0 ft for Free Fall 3.5 ft for Deceleration 1.0 ft for D-ring slide 2.0 ft for Safety Factor 12.5 ft clearance required Freefall + Deceleration + Safety Factor Clearance Calculations
What if I don’t have 12.5 ft of clearance? Raise the anchor point Use a shorter lanyard Use a SRL SRL Example 3.5 ft for Deceleration 1.0 ft for D-ring slide 2.0 ft for Safety Factor 6.5 ft clearance required Clearance Calculation
