OSHA 1910.212 Machine Guarding: Requirements, Risk Assessment and AI Documentation
What does OSHA 1910.212 mandate for manufacturing plants? Under 29 CFR 1910.212(a)(1), employers must provide one or more methods of machine guarding to protect operators and other employees in the machine area from hazards such as those created by point of operation, ingoing nip points, rotating parts, flying chips, and sparks. Guards must be affixed to the machine where possible and secured elsewhere if attachment to the machine is not feasible. The guard must not create an accident hazard in itself. Penalties for serious violations exceed $16,131 per violation, while willful or repeated citations can reach $161,323 per machine under 2026 OSHA civil penalty rates.
