Fall Protection is a system that is designed to protect personnel from the risk of falls when working at elevated heights. Some examples are platforms with guardrails, Bucket Trucks or Aerial Lifts with work platforms. A is for the Anchor Point. Federal Law requires an Anchor Point that is structurally sound, good for a static force of 5000lbs.
Some options are permanent or reusable anchors that can be attached to roof decks or steel beams.
B is for the Body Harness. The harness straps around your chest, buttocks and thighs. Newer fabrics make the webbing stretchable providing for a more comfortable fit. C is for the Connecting Device. This connects the Body Harness to the Anchor Point.
