  CHAPTER I--MINE SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT OF LABOR
 
PART 22--PORTABLE METHANE DETECTORS--Table of Contents
 
Sec. 22.10  Approval plate.

    (a) Attachment to be made by manufacturers. (1) Manufacturers shall 
attach, stamp, or mold an approval plate on each permissible methane 
detector. The plate shall bear the emblem of the Mines Safety and Health 
Administration and be inscribed as follows:

    Permissible Methane Detector (or Permissible Methane Indicating 
Detector) Approval No. ------ issued to the -------------- Company.

    (2) When deemed necessary, an appropriate caution statement shall be 
added. The size and position of the approval plate shall be satisfactory 
to MSHA.
    (b) Purpose of approval plate. The approval plate is a label that 
identifies the device so that anyone can tell at a glance whether it is 
of the permissible type or not. By the plate, the manufacturer can point 
out that his detector complies with MSHA's requirements and that it has 
been approved for use in gassy mines.
    (c) Use of approval plate. Permission to place MSHA's approval plate 
on his detector obligates the manufacturer to maintain the quality of 
his product and to see that each detector is constructed according to 
the drawings that have been accepted by MSHA and are in MSHA's files. 
Detectors exhibiting changes in design that have not been approved are 
not permissible and must not bear MSHA's approval plate.
    (d) Withdrawal of approval. MSHA reserves the right to rescind for 
cause at any time any approval granted under this part.
