(a) A certificate of approval will be accompanied by a photograph of
an approval plate, bearing the emblem of the Mine Safety and Health
Administration and spaces for the approval number, the type, the serial
number, and ventilation requirement; the name of the complete assembly; and
the name of the applicant.
(b) The applicant shall reproduce the design as a separate plate,
which shall be attached, in a suitable place, on each complete assembly to
which it relates. The size, type, and method of attaching and location of an
approval plate are subject to MSHA's approval. The method of affixing the
approval plate shall not impair the permissibility (explosion-proof) features
of the complete assembly of mobile diesel-powered transportation
equipment.
(c) The approval plate identifies the equipment, to which it is
attached, as permissible and is the applicant's guarantee that the equipment
complies with the requirements of this part. Without an approval plate no
equipment is considered permissible under the provisions of this part.
(d) Use of the approval plate obligates the applicant to whom the
certificate of approval was granted to maintain in his plant the quality of
each complete assembly bearing it and guarantees that it is manufactured and
assembled according to the drawings, specifications, and descriptions upon
which a certificate of approval was based.
