Excerpt from "Arc welding from suspended scaffolds: feasibility of grounding."
Specifically, you asked for an interpretation of a provision, 29 CFR 1926.451(f)(17)(iv), that addresses arc welding from a suspended scaffold and which requires that a grounding lead be connected from the scaffold to the structure. You listed several potential hazards that exist inside coal or oil fired boilers, and you were concerned that the added weight to the scaffold from the ground lead might compromise the manufacturer's safe working load or create an off - center distribution of weight.
