PART 22--PORTABLE METHANE DETECTORS--Table of Contents
 
Sec. 22.8  Material required for MSHA records.

    In order that MSHA may know exactly what it has tested and approved, 
it keeps detailed records covering each investigation. These records 
include drawings and actual equipment as follows:
    (a) Drawings. The original drawings submitted with the application 
for the tests and the final drawings which the manufacturer must submit 
to MSHA before the approval is granted to show the details of the 
detector as approved, are retained. These drawings are used to identify 
the detector in the approval and as a means of checking the future 
commercial product of the manufacturer.
    (b) Actual equipment. If MSHA so desires, parts of the detectors 
that are used in the tests will be retained as records of the equipment 
submitted. If the detector is approved, MSHA will require the 
manufacturer to submit one of his detectors, with the approval plate 
attached, as a record of his commercial product.
