Authorized personnel must follow established procedures to disconnect energy or shut down machines, equipment, processes, or circuits. The operator or technician may need to shut down the machine in sequence to ensure that potential hazards and machine damage are minimized.

Isolate the power source of the device

Disconnect equipment from all external hazardous energy sources

Locate all the energy isolators listed in the LOTO program one by one

Adjust these devices to stop the energy flow of the device

PPE may be required

Common energy isolation technology: close the valve, open the circuit breaker

Energy isolation of equipment

All operating controllers must be closed or returned to neutral by authorized personnel.

Energy isolation devices must be used to prevent unintentional opening of valves, switching or other operations on equipment/systems by others.
