3:1 A Personal Fall Arrest System ("PFAS") is used to stop you during a fall from a working level. It usually is made up of an anchorage, connectors, and body harness, and may include a lanyard, deceleration device, or lifeline. 1926.500(b)
3:2 An anchorage is a secure point of attachment for lifelines, lanyards, or deceleration devices. 1926.500(b)
3:3 A body harness consists of straps you wear to distribute forces from a fall over different areas of your body to minimize possible injury. 1926.500(b)
3:4 A connector connects parts of your PFAS and positioning device systems together, such as carabiners, buckles, dee-rings, snap-hooks, etc. 1926.500(b)
3:5 Failure is a load refusal, breakage, or separation of component parts. "Load refusal" is the point at which the ultimate strength is exceeded. 1926.500(b)
3:6 Free-fall distance is the vertical distance between the fall arrest attachment point on your body belt or harness at the start of your fall and the point the system starts to apply force to stop the fall. 1926.500(b)
3:7 A positioning device system is a body harness system rigged to support you on an elevated vertical surface, such as a wall, allowing you to work with both hands free while leaning. 1926.500(b)
3:10 Supervisors will ensure that all PFAS comply with OSHA regulations. 1926.502(d)
3:11 Body belts are no longer allowed for a PFAS. 1926.502(d)
3:12 Connectors used for your PFAS must have a corrosionresistant finish and smooth surfaces to prevent damage to any other part of the system. 1926.502(d)(2)
