1. Identify machines or equipment that need to be locked.
2. Turn off the machine or equipment and ensure that all moving parts are completely stopped.
3. Find the power supply and cut it off
4. Individually lock the energy isolator if necessary (locking may not be necessary if the key is controlled by only one worker).
5. Test that other workers are not near the machine to see if all power is off.
Continue to lock
In some cases - such as during a shift change - the worker keeps the lock on to maintain the continuity of the lock. When this happens, the people concerned need to develop procedures. To accommodate shifts or personnel changes. This includes the methodical transfer of responsibility for the control of the functional isolation device from the hands of off-duty workers to the hands of shift workers.
If the energy isolation unit is not locked during the shift. New workers must repeat the lock steps as needed.
Interlocking systems such as conveyor belts require special methods. One of the following steps must be taken when testing the locked part of the interlocking system:
Chain order must be completely completed or completely skipped
There has to be another way to fit the energy sequester has been cut off. For example, consult a qualified person who knows the chain system well.
