Application of Grounds

DOE-HDBK-1092-2004

circuit have been deenergized. If the circuit to be tested is over 600 V nominal, the test equipment

shall be checked for proper operation immediately before and immediately after this test. This test

is also recommended for systems of 600 V or less. Testing shall be performed as if the circuit is

energized. The voltage verification device used shall be rated for the application. Proximity testers

and solenoid-type devices should not be used to test for the absence of alternating current (AC)

voltage. See 2.13.4.6 for further information.

2.13.2.2

APPLICATION OF GROUNDS

Personnel protective grounds shall be applied on circuits 600 V and above or on lesser voltages

where residual charges may accumulate. Personal protective grounds shall be selected and

installed in accordance with appropriate standards. (See sections 4.6 and 7.5). Consideration

shall be given to step and touch potentials in the area of the temporary ground connections.

2.13.3 REENERGIZING EQUIPMENT

The following requirements shall be met before circuits or equipment are reenergized, even

temporarily.

2.13.3.1

TESTS AND VISUAL INSPECTIONS

A qualified worker shall conduct tests and visual inspections to verify that all personnel are in the

clear and that all tools, electrical jumpers, shorts, grounds, and other such devices have been

removed so that the circuits and equipment can be safely energized.

2.13.3.2

WARNING EMPLOYEES

Employees exposed to the hazards associated with reenergizing the circuit or equipment shall

be warned to stay clear of circuits and equipment.

2.13.3.3

REMOVING LOCK AND TAG

Each lock and tag shall be removed by applying the following:

1. Each lockout or tagout device shall be removed from each energy-isolating device by the

authorized employee who applied the lockout or tagout device, or under their direct

supervision, or as stated below.

2. Exception: When the authorized employee who applied the lockout or tagout device is not

available to remove it, that device may be removed under the direction of his or her

supervisor. Extreme care shall be taken and specific procedures shall be followed, including,

at a minimum, the following elements:

a. Verification by the supervisor that the authorized employee who applied the device is not

at the affected facility

b. Making all reasonable efforts to contact the authorized employee to inform him or her

that the lockout or tagout device has been removed

c. Ensuring that the authorized employee has this knowledge before he or she resumes

work at the affected facility
