OSHA 1910.147 machine-specific energy control
Preventing accidental machine startup during maintenance is a critical life-saving protocol in any industrial facility. Generating a machine-specific LOTO procedure ensures that all hazardous energy sources—whether electrical, mechanical, hydraulic, or pneumatic—are properly isolated and verified before work begins. Maintenance managers rely on these standardized placards to comply with federal safety mandates and protect technicians from catastrophic injuries.
Yes, OSHA requires machine-specific procedures, unless the equipment has a single energy source that is easily isolated, locked out, and completely removes all hazards.
Hazardous energy includes electrical, mechanical, hydraulic, pneumatic, chemical, thermal, and even gravity or stored mechanical energy (like compressed springs).
Federal regulations require a periodic inspection of energy control protocols at least annually to ensure the steps are accurate and employees are following them correctly.
No, locks used for energy isolation must be standardized within the facility, distinctively colored, individually keyed, and used for no other purpose than safety isolation.
