 INSPECTION OF ELECTRICAL EQUIPMENT AND WIRING; CHECKING AND TESTING METHANE
MONITORS (§ 45.2-814)

A. Electrical equipment and wiring shall be inspected by a certified person at
least weekly if it is located underground and at least monthly if it is located
on the surface. Such equipment and wiring shall be inspected more often if doing
so is necessary to ensure safe operating conditions. Any hazardous condition
that is found shall be promptly corrected or the equipment or wiring shall be
removed from service. Records of such inspections shall be maintained at the
mine for a period of one year.

B. A functional check of methane monitors on electrical face equipment shall be
conducted to determine whether such monitors are de-energizing the electrical
face equipment properly. Such check shall be (i) made on each production shift,
(ii) conducted by the equipment operator in the presence of a mine foreman, and
(iii) recorded in the on-shift report of the mine foreman.

C. To determine the accuracy and operation of methane monitors on electrical
face equipment, weekly calibration tests of such monitors shall be conducted
with a known mixture of methane at the flow rate recommended by the methane
monitor manufacturer. A record of the results shall be maintained.

D. Required methane monitors shall be maintained in permissible and proper
operating condition.
