(a) Except as provided in paragraph (f) of this section, an
individual is a qualified person within the meaning of §§75.511 and 75.512 to perform electrical work
(other than work on energized surface high-voltage lines) if:
(1) He has been qualified as a coal mine electrician by a
State that has a coal mine electrical qualification program approved by the
Secretary; or,
(2) He has at least 1 year of experience in performing
electrical work underground in a coal mine, in the surface work areas of an
underground coal mine, in a surface coal mine, in a noncoal mine, in the mine
equipment manufacturing industry, or in any other industry using or
manufacturing similar equipment, and has satisfactorily completed a coal mine
electrical training program approved by the Secretary; or,
(3) He has at least 1 year of experience, prior to the
date of the application required by paragraph (c) of this section, in
performing electrical work underground in a coal mine, in the surface work
areas of an underground coal mine, in a surface coal mine, in a noncoal mine,
in the mine equipment manufacturing industry, or in any other industry using
or manufacturing similar equipment, and he attains a satisfactory grade on
each of the series of five written tests approved by the Secretary and
prescribed in paragraph (b) of this section.
(b) The series of five written tests approved by the Secretary shall
include the following categories:
(1) Direct current theory and application;
(2) Alternating current theory and application;
(3) Electric equipment and circuits;
(4) Permissibility of electric equipment; and,
(5) Requirements of Subparts F through K of this Part
75.
(c) In order to take the series of five written tests approved by the
Secretary, an individual shall apply to the District Manager and shall
certify that he meets the requirements of paragraph (a)(3) of this section.
The tests will be administered in the Coal Mine Safety and Health Districts
at regular intervals, or as demand requires.
(d) A score of at least 80 percent of each of the five written tests
will be deemed to be a satisfactory grade. Recognition shall be given to
practical experience in that 1 percentage point shall be added to an
individual's score in each test for each additional year of experience beyond
the 1 year minimum requirement specified in paragraph (a)(3) of this
section; however, in no case shall an individual be given more than 5
percentage points for such practical experience.
(e) An individual may, within 30 days from the date on which he
received notification from the Administration of his test scores, repeat
those on which he received an unsatisfactory score. If further retesting is
necessary after this initial repetition, a minimum of 30 days from the date
of receipt of notification of the initial retest scores shall elapse prior
to such further retesting.
(f) An individual who has, prior to November 1, 1972, been qualified
to perform electrical work specified in §§75.511 and
75.512 (other than work on energized surface
high-voltage lines) shall continue to be qualified until June 30, 1973. To
remain qualified after June 30, 1973, such individual shall meet the
requirements of either paragraph (a)(1), (2), or (3) of this section.
(g) An individual qualified in accordance with this section shall, in
order to retain qualification, certify annually to the District Manager, that
he has satisfactorily completed a coal mine electrical retraining program
approved by the Secretary.
