Operating with the equipment, load line or load (or any part of them) inside the Table A minimum approach distance of an energized line is forbidden unless the employer shows every one of the following. It has determined the work cannot feasibly be done without breaching Table A, and after consulting the utility, that deenergizing and grounding or relocating the line is infeasible. The utility or a registered professional engineer qualified in power transmission and distribution sets the minimum clearance to be kept given on-site conditions, weighing atmospheric conductivity, stopping time for equipment and load, wind, line sway, lighting and similar factors (for Subpart V work the employer's 1926.960(c)(1)(i) approach distances apply instead). A planning meeting of the employer and the utility (or the engineer) must settle procedures, which at minimum include: disabling automatic reclosing on the circuit if its design allows; a dedicated spotter in continuous contact with the operator, with a visual aid, positioned to judge distance, communicating as needed and giving timely information; an elevated warning line or barricade, independent of the crane, visible to the operator directly or by video (not for Subpart V work); an insulating link/device fitted between the load and the load line's end (not for Subpart V work; transitional substitutes allowed only until November 8, 2011 and November 8, 2013 have lapsed); nonconductive rigging whenever rigging could come inside the Table A distance; use of any automatic range limiting device fitted, set to the determined clearance; nonconductive tag lines; barricades at least 10 feet from the equipment, or as far as feasible; no worker other than the operator touching the crane or the portion of load line higher than the insulating link, and ground-based remote operators using isolating wireless controls or insulating mats; only essential personnel near crane and load; proper grounding; and insulating line hose or cover-up installed by the utility unless unavailable for the voltage. The procedures must be documented and immediately available on site, reviewed in a meeting of the equipment user and utility or engineer with the operator and other workers in the area, and actually implemented. The utility or engineer and all employers involved must name one person to direct implementation, empowered to halt the work whenever needed. If a problem arises or the procedures prove inadequate, the employer must stop safely and either develop new procedures or have the line deenergized and visibly grounded or relocated before resuming. Devices used must follow the maker's conditions of use, and operators and crew must be trained per 1926.1408(g).
