The territorial unit shall test the equipment in the presence of the operator. Testing should exclude interlocking devices or other factors that may interfere with effectiveness. If the isolation is confirmed to be invalid, it is up to the territorial unit to take appropriate measures to ensure the safety of the operation.
During the operation of the equipment (such as trial operation, test, power transmission, etc.), the tester of the territorial unit shall confirm and test the energy isolation again, fill in the energy isolation list again, and both parties shall confirm and sign before resuming the operation.
During the work, if the personnel of the operating unit ask for retesting and confirmation, it shall be confirmed and approved by the person in charge of the project of the subordinate unit before retesting.
