Lockout/Tagout Compliance for Aerospace

29 CFR 1910.147 — Requires employers to establish a written program and procedures to disable machinery and prevent the release of hazardous energy during service or maintenance.

Any general-industry employer whose workers service or maintain machines or equipment where unexpected energization, start-up, or release of stored energy could cause injury.

How Lockout/Tagout Applies to Aerospace

Aerospace facilities have the broadest LOTO scope of any industry — autoclaves, hydraulic test stands, paint booths, robotics, machining centers, and high-voltage test cells. Procedures must reflect the multi-energy nature of test stands and cleanroom equipment, and IIPP integration is required in California.

Key Requirements

  • Written energy-control program covering all machines and energy sources
  • Equipment-specific lockout procedures (electrical, hydraulic, pneumatic, mechanical, thermal, chemical, gravity)
  • Authorized-employee, affected-employee, and other-employee training with documentation
  • Annual periodic inspection of each procedure by an authorized employee not using it
  • Lockout devices and tags issued, controlled, and standardized across the facility
  • Group lockout procedures for multi-person work
  • Shift-change and contractor coordination protocols

Most-Cited Violations

  • 1910.147(c)(4)(i) — No equipment-specific written procedures
  • 1910.147(c)(6)(i) — Annual inspection not performed or not documented
  • 1910.147(c)(7)(i) — Authorized employee training missing or stale
  • 1910.147(c)(1) — No written energy-control program at all

Typical fine range: $8,000–$32,000 per Serious citation (settled). Repeat or Willful: $50,000–$165,514.
