Sec. 20.13  Approval plate.

    The manufacturer shall attach, stamp, or mold an approval plate on 
the battery container or housing of each permissible lamp. The plate 
shall bear the emblem of the Mine Safety and Health Administration, and 
be inscribed as follows: ``Permissible ---------- Lamp. Approval No. --
------------------ issued to the -------------------- Company.'' When 
deemed necessary, an appropriate caution statement shall be added. The 
size, material, and position of the approval plate shall be satisfactory 
to MSHA.
    (a) Purpose of approval plate. The approval plate is a label which 
identifies the lamp so that anyone can tell at a glance whether the lamp 
is of the permissible type or not. By it the manufacturer can point out 
that his lamp complies with specifications of MSHA and that it has been 
adjudged safe for use in gassy and dusty mines.
    (b) Use of approval plate. Permission to place MSHA's approval plate 
on his lamp obligates the manufacturer to maintain the quality of his 
product and to see that each lamp is constructed according to the 
drawings which have been accepted by MSHA for this lamp and which are in 
the MSHA files. Lamps exhibiting changes in design which have not been 
approved are not permissible lamps and must not bear MSHA's approval 
plate.
    (c) Withdrawal of approval. MSHA reserves the right to rescind for 
cause at
