High voltage, deep vaults, long rights-of-way — one library covers them.

§1910.269 is a small rulebook unto itself — minimum approach distances, arc-rated clothing calculations, grounding, enclosed spaces versus permit spaces, line-clearance tree trimming — with its own definitions that interact with the general standards around it. Crews servicing gas distribution add Part 192's operator qualification and integrity management obligations. The compliance question is rarely whether a rule exists; it's which of the overlapping rules controls this task.

RegLogic's search operates across the whole library at once, and the color-coded formatting keeps 269's deeply nested provisions readable. The enclosed-space vs. permit-space distinction — a classic utilities trap — is exactly the kind of question the attached interpretation letters resolve.

Storm response doesn't happen where the Wi-Fi is. The GR Reader app carries the full library offline for vault crews, line crews, and mutual-aid deployments. Team notes push the utility's own work rules — switching procedures, MAD tables, grounding practices — to every device alongside the federal text they implement.
