1. PERSONAL FALL ARREST SYSTEMS

(A) GENERAL TEST CONDITIONS

Lifelines, lanyards, and deceleration devices should be attached to an anchorage and connected to the body-belt or body harness in the same manner as they would be when used to protect employees, except that lanyards should be tested only when connected directly to the anchorage, and not when connected to a lifeline.
The anchorage should be rigid, and should not have a deflection greater than .04 inches (1 cm) when a force of 2,250 pounds (10.01 Kn) is applied.
The frequency response of the load measuring instrumentation should be 100 Hz.

A personal fall protection arrest system (PFAS) is comprised of three vital components: an anchorage, body wear (full-body harnesses), and a connecting device (a shock-absorbing lanyard or self-retracting lifeline). The safety of at-height workers depends on these three components, and each one must be in place and used properly to provide maximum worker protection.
When discussing fall protection, anchorage connectors and full body harnesses receive a lot of attention. We don’t always stop to think about connecting devices like self-retracting lifelines or shock-absorbing lanyards, and yet these are the two components that bear the greatest forces during a fall.
