When to use a safety harness? Whenever there is any potential for a worker to fall 6’ or more, there must be some kind of fall protection in place to prevent it. You have options: Working in a roof: Working on a roof: (within truss framing) (on top of sheathing) Can you set up scaffolding Can you set up HUGS sections and move them (Horizontal Undereave around so that they are always Guardrail System) around the positioned under workers? entire perimeter of the roof? YES NO NO YES You’re good; no You’re good; no harness necessary. Use a Safety Harness. harness necessary. Terminology: What are all those pieces? Harness Safety Rope Truss Spreader Bar Anchor Rope Grab “Yo-yo” Connector (Retracting Lanyard) Roof Peak Lanyard Anchor (or “D Ring”) Installation: 1) Inspect all pieces of the system for wear and damage: • Inspect harness and lanyard for loose stitching and worn webbing. • Torn stitches indicate the system has absorbed a shock; never reuse a harness or lanyard that has been subjected to a fall. Send them back to the manufacturer for inspection and repair/replacement. • Examine the rope for fraying. • All clips must have a locking gate; inspect before use to ensure gate and lock are working. Do not use any equipment which is damaged or reasonably suspected to be damaged. Installation: 2) Strap on the safety harness according to the manufacturer's instructions. Straps worn too loosely can result in serious injury in the event of a fall: Loose chest straps can slide up to a worker’s neck during fall arrest. Loose vertical straps can result in a worker being suspended horizontally or upside- down after a fall. Loose leg straps can result in blood constriction while suspended after a fall. Installation: 3) Fasten the roof anchor to framing according to the manufacturer's instructions. There are two types of anchors, depending on where you’ll be working. For each type: • Attach anchor directly above the work to be done. • If work will be done in a large area, attach several anchors. • Anchors must be attached securely and directly to trusses, not just sheathing or bracing. • Use lag screws or 16d nails (per manufacturer’s specifications). Truss Spreader Bars can be used during truss standing, Roof Peak Anchors can be roof framing, and the majority of sheathing stages – just used at sheathing, shingling, not after the roof has been completely sheathed. and finished stages of roofing. Installation: 3) Fasten the roof anchor to framing according to the manufacturer's instructions. Installing Peak Anchors Double-D anchors can be used permanently. Single-Ds can not be used permanently. Installing a permanent peak anchor: Installing a temporary peak anchor: 1. Shingle roof up to the second-to-last 1.
