(a) Properly insulate all test lead clips,
terminals, and wires.
(b) Avoid direct contact with bare test lead
terminals.
(c) Place the reference electrodes in position for
measurement prior to making any test
connections.
(d) Connect the lead to the reference electrode
and reel the wire back to the test location.
(e) Connect the other test lead to the instrument
and then to the structure.
(f) Connect the reference electrode lead to the
instrument.
(g) When the tests are complete, disconnect in
reverse order. NOTE: Close-interval pipe-to-
electrolyte surveys using long lead wires require
special procedures and precautions.
7.2.8 Tools, instruments, or other implements shall
not be handed at any time between a person
standing over a ground mat or grounding grid and a
person who is not over the mat or grid.
7.2.9 Grounding facilities for the purpose of
mitigating AC effects should be carefully tested at
regular intervals to ascertain the integrity of the
grounding system.
7.2.9.1 No disconnection or reconnection shall
be allowed when a flammable or explosive
atmosphere is suspected without first testing to
ensure a safe atmosphere.
7.2.9.2 No one shall make contact with the
structure, either directly or through a test wire,
while a grounding grid is disconnected for test
purposes.
7.2.9.3 Measurement of the resistance to earth
of disconnected grounds shall be made promptly
to minimize personnel hazards.
7.2.10 All interference mitigation devices and test
equipment should be maintained in accordance with
the manufacturer’s instructions.
