The control of hazardous energy (lockout/tagout)
29 CFR § 1910.147
29 CFR § 1910.147 is the federal OSHA standard governing the control of hazardous energy (lockout/tagout), setting mandatory general industry employer duties, and Michigan applies MIOSHA Safety Standard Part 85 (R 408.18501–R 408.18599) that inspectors verify and enforce through citations. Employers should document hazard assessments, training and inspections so each requirement can be demonstrated on request.
Statutory Comparison
| Requirement | Baseline Fed Code | State Rule | Enforced Metric |
|---|---|---|---|
| Servicing or maintaining machines, equipment, or processes where unexpected energization, start-up, or stored-energy release could cause injury | 29 CFR § 1910.147 | Part 85 establishes minimum lockout/tagout requirements and adopts 29 CFR 1910.147 by reference. Apply Part 85 alongside applicable MIOSHA standards; specific MIOSHA lockout/tagout provisions govern where they conflict. The cited rule does not establish a general independent-tagging restriction beyond those requirements. | MIOSHA Part 85 - Machine-specific energy control procedures under 29 CFR 1910.147 |
