The isolation device that can be locked shall be locked by an authorized person and the isolation device shall be in a "secure" or "closed" state;
Tag should be used when the lock itself cannot display the lock date and time and the lock holder information.
For the isolation of equipment with voltage greater than 360V, the first lock shall be put on by the electrical personnel, and then the second lock shall be put on by the production personnel/supervisor; Lock/Tagout setting and undoing should only be done in the presence of electrical personnel.
The supervisor of the area where the operation is located shall be responsible for setting up the production personnel/supervisor lock and the listing on the isolation equipment. Therefore, at least two locks (the operator's personal lock and the supervisor lock) shall be set up first and removed last during the isolation. (Exceptions: When isolating equipment normally operated by a designated person, the master lock/tag may not be set).
Blind isolation also requires setting the tag Tagout;
When the distance between the actual site isolation point and the control point is far away, it is recommended to put labels on the control point.
