Machine Guarding Compliance for Aerospace

29 CFR 1910.212 — Requires guards to protect operators and other workers in the area from hazards created by point of operation, ingoing nip points, rotating parts, flying chips, and sparks.

Any general-industry employer with mechanical machinery or equipment.

How Machine Guarding Applies to Aerospace

Aerospace machining operates large CNC mills, lathes, and routers — light curtains, interlocked enclosures, and presence-sensing devices must meet ANSI B11.19 and Category 3/4 functional safety where required.

Key Requirements

  • Guards on point of operation, power transmission, and other moving parts
  • Guards must be affixed to the machine where possible
  • Guards must not create their own hazard
  • Anchoring of fixed machines
  • Specific point-of-operation guarding for power presses, woodworking, abrasive wheels, mills, and shears

Most-Cited Violations

  • 1910.212(a)(1) — Point of operation unguarded
  • 1910.212(a)(3)(ii) — Machine point-of-operation does not prevent operator from any part of the body in the danger zone
  • 1910.212(b) — Anchoring of fixed machinery missing

Typical fine range: $10,000–$32,000 per Serious citation (settled). Amputations elevate this to Willful range.
