SUPPLEMENTARY INFORMATION: 

I. Background

    Section 103(h) of the Federal Mine Safety and Health Act of 1977 
(Mine Act) (Pub. L. 91-173, as amended by Pub. L. 95-164), 30 U.S.C. 
813(h), authorizes the Mine Safety and Health Administration (MSHA) to 
collect information necessary to carry out its duty in protecting the 
safety and health of miners. Further, section 101(a) of the Mine Act, 
30 U.S.C. 811, authorizes the Secretary of Labor (Secretary) to 
develop, promulgate, and revise as may be appropriate, improved 
mandatory health or safety standards for the protection of life and 
prevention of injuries in coal or other mines.
    Inadequate maintenance of electric equipment is a major cause of 
serious electrical accidents in the coal mining industry. It is 
imperative that mine operators adopt and follow an effective 
maintenance program to ensure that electric equipment is maintained in 
a safe operating condition to prevent electrocutions, mine fires, and 
mine explosions. MSHA regulations require the mine operator to 
establish an electrical maintenance program by specifying minimum 
requirements for the examination, testing, and maintenance of electric 
equipment. The regulations also contain recordkeeping requirements that 
help operators in implementing an effective maintenance program.

(a) Examinations of Electric Equipment

 Underground Coal Mines
    (1) 30 CFR 75.512 requires that all electric equipment be 
frequently examined, tested, and maintained by a qualified person to 
assure safe operating conditions. When a potentially dangerous 
condition is found on electric equipment, such equipment shall be 
removed from service until such condition is corrected and that a 
record of such examinations be kept. 30 CFR 75.512-2 specifies that 
required examinations and tests be made at least weekly.
    (2) 30 CFR 75.703-3(d)(11) requires that all grounding diodes be 
tested, examined, and maintained as electric equipment and records of 
these activities be kept in accordance with the provisions of 30 CFR 
75.512.

examinations be kept. 30 CFR 77.502-2 requires these examinations and 
tests at least monthly.

(b) Examinations of High-Voltage Circuit Breakers

 Underground Coal Mines
    (1) 30 CFR 75.800 requires that circuit breakers protecting high-
voltage circuits, which enter the underground area of a coal mine, be 
properly tested and maintained as prescribed by the Secretary. Such 
breakers must be equipped with devices to provide protection against 
under-voltage grounded phase, short circuit, and overcurrent. 30 CFR 
75.800-3 requires that such circuit breakers be tested and examined at 
least once each month. Tests must include: (1) Breaking continuity of 
the ground check conductor, where ground check monitoring is used; and 
(2) Actuating at least two (2) of the auxiliary protective relays. 
Examination must include visual observation of all components of the 
circuit breaker and its auxiliary devices, and such repairs or 
adjustments as are indicated by such tests and examinations shall be 
carried out immediately. 30 CFR 75.800-4 requires that a record of the 
examinations and tests be made. These records must be made in a secure 
book that is not susceptible to alteration or electronically in a 
computer system so as to be secure and not susceptible to alteration. 
These records shall be retained at a surface location at the mine for 
at least one year and shall be made available to authorized 
representatives of the Secretary, the representative of miners, and 
other interested persons.
    (2) 30 CFR 75.820 requires persons to lock-out and tag
