                      Subpart A--General Provisions
 
Sec. 33.11  Approval plates.

    (a) A certificate of approval will be accompanied by a photograph of 
a design for an approval plate, bearing the emblem of the Mine Safety 
and Health Administration, the name of the applicant, the name of the 
unit, the approval number or space for the approval number (or numbers 
if permissibility of electrical parts is involved), spaces for the type 
and the serial numbers of the unit, conditions of approval, and 
identifying numbers of the dust-collector parts. When deemed necessary 
by MSHA, an appropriate statement shall be added, giving the precautions 
to be observed in maintaining the unit in an approved condition.
    (b) An approval plate for a unit designed for use in a nongassy coal 
mine shall state that any electrical parts are not certified for use in 
a gassy coal mine. (See Sec. 33.38(c).)

    (c) The applicant shall reproduce the design either as a separate 
plate or by stamping or molding it in some suitable place on each unit 
to which it relates. The size, type, and method of attaching and 
location of an approval plate are subject to the approval of MSHA. The 
method of affixing the plate shall not impair the dust-collection or 
explosion-proof features of the unit.
    (d) The approval plate identifies the unit, to which it is attached, 
as permissible, and is the applicant's guarantee that the unit complies 
with the requirements of this part. Without an approval plate, no unit 
has the status of ``permissible'' under the provisions of this part.
    (e) Use of the approval plate obligates the applicant to whom the 
certificate of approval was granted to maintain the quality of each unit 
bearing it and guarantees that it is manufactured and assembled 
according to the drawings and specifications upon which a certificate of 
approval was based. Use of the approval plate is not authorized except 
on units that conform strictly with the drawings and specifications upon 
which the certificate of approval was based.
