The grid is a network of bare energized conductors strung across the country at\nvoltages that kill on contact, and it has to keep running while people work on it\n— in storms, at night, with the load still flowing. A lineworker exists to build,\nmaintain, and restore the overhead and underground power system — setting poles,\nstringing conductor, switching, and clearing faults — and to do it without being\nelectrocuted, falling, or killing a coworker or the public. The craft is the\nsharpest edge in the trades: the worker's life depends on a chain of redundant\nprecautions, and a single broken link — a missed ground, a blown clearance, an\nunverified isolation — is fatal, not inconvenient. The work matters because the\nlights, the heat, and the hospital come back only when the lineworker climbs the\npole.

You stay outside it, or you cover up and use rubber gloves and sticks\n rated for the voltage. There is no \"just for a second.\"\n- **Test dead, ground, and only then it's dead.** De-energized work means\n isolating the source, locking it out, testing for absence of voltage with a\n rated tester, and applying personal protective grounds to bracket the work — so\n any accidental re-energization or induced voltage trips to ground instead of\n through you.\n- **Treat every conductor as energized until proven otherwise.** Backfeed,\n induction from parallel lines, and capacitive charge keep \"dead\" lines\n dangerous. Belief never substitutes for a tester and a ground.\n- **Cover up and keep your cover.** Insulating blankets, hoses, and line guards\n create a barrier so a slip doesn't become a contact. Establish cover before you\n work and never reach past it.\n- **One contact is enough; never bridge two potentials.** Current needs a path;\n the lineworker's job is to never be that path between a conductor and ground or\n between two phases. Work one potential at a time.\n- **Fall protection on the structure.** Above the working height you're tied off\n or in a bucket with a harness; the pole and the bucket kill by fall as well as by\n current.","html":"Climbing gear — hooks (gaffs), body belt, and fall-restraint/fall-arrest, or the\nbucket truck with harness; rubber insulating gloves and sleeves, rated and tested,\nwith leather protectors; insulating blankets, line hose, and cover-up; hot sticks\nand live-line tools (shotgun stick, telescoping sticks, clamp sticks); a rated\nvoltage tester/detector and personal protective ground sets; hydraulic press and\nsplicing tools for connectors; the digger derrick and crane for poles and\ntransformers; tensioners and dynamometers for sagging; and the switching and\nclearance procedures that are as much "tools" as any hardware.
