multi-lock tree or group lock box. (See Notes 2 & 4, Page 2)
Test attempt to operate the piece of equipment or component to verify that it has been
properly isolated and/or immobilized.
• Use the proper device (Voltmeter or Tic Tracer depending upon the Voltage) to test for
absence of voltage. (Verify proper instrument operation before and after testing.)
• Do an assessment to make sure that all possible hazards have been accounted
for and mitigated.
Perform the work safely. Follow site specific Safe Work Procedures where available.
Notify all affected persons when the work has been completed and let them know that you
intend to re-energize the equipment or component.
Remove your lock and tag when;
• the work has been completed and the equipment has been inspected to assure that it
is safe to test or be returned to duty.
• all tools, restraints and testing devices have been removed and properly stored. As
well as any parts, lubricants and other materials have been removed and stored.
• all persons have been cleared from the immediate area and machine guards, where
