Fall Protection Awareness Class Instructor: Ken Coats, Central Region Safety BDM
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
Connectors • Snap hooks and carabiners must be self-locking and self-closing. • All connectors must meet 5000lbs. • All connectors must be connected to a compatible connection. • NEW ANSI Standard (11/2007) • Connectors shall meet 5000 lbs. and the gate shall meet 3600 lbs.
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
Anchorage and Anchorage Connectors • Anchorages are defined as secure points to attach an anchorage connector to be used in conjunction with a fall protection or rescue system. • Anchorages used for fall protection shall be capable of supporting a load of 5,000 lbs. per worker, unless certified by a qualified person who maintains a 2:1 safety factor. • The maximum arresting force (MAF) on the anchor shall be no more than 1,800 lbs.
OSHA 1926.502 (d) (20):The employer shall provide for prompt rescue of employees in the event of a fall or shall assure that employees are able to rescue themselves. ANSI Z359.2 Rev.
