What do the safety bulletins say about overhead power lines, lighting rigged on aerial lifts, 480 V systems and PPE for lighting tasks, and where do they disagree?

Partially verified: the curator re-read S19; S15, S16, S17, S18 were not re-read by the curator and rest on the producer's pinned reading. Bulletin #22 (2017) allows lighting, camera and diffusion rigged onto boom-lift guardrails only within manufacturer limits with extra training (otherwise not at all), prohibits lifts over energised high-voltage lines, and says rigged lifts should not be operated over low-voltage lines (600 V or less). Clearance tables are in an Addendum A that #22 names as '#22 Addendum A' while the web URL labels it 23a (naming inconsistency kept). Curator qualifications: Partially verified: the curator re-read S19; S15, S16, S17, S18 were not re-read by the curator and rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S15: HTTP 200, bytes equal to the producer pin; S16: HTTP 200, bytes equal to the producer pin; S17: HTTP 200, bytes equal to the producer pin; S18: HTTP 200, bytes equal to the producer pin. Documents read 2026-10-22; no legal conclusions; guidance only. Addendum A table text not in the fetched HTML (item-level gap); Addenda C (480 V) and D (PPE) from producer reading. Limitations: Documents read 2026-10-22; no legal conclusions; guidance only. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
