Lockout/Tagout
The MiOSHA law "Lock Out/Tag Out of Hazardous Energy" is designed to prevent the unexpected release of hazardous energy. Any time that a machine guard is removed, or service is performed that could release energy, the system must be shut off, de-energized, and the controls or energy supply locked in the off position. This applies to all energy types: electric, thermal, hydraulic, chemical, and potential (heavy items that are suspended, or under tension).
