(a) Prior to the issuance of a certificate of approval or
performance, necessary government personnel, representatives of the
applicant, and such other persons as may be mutually agreed upon, may observe
the investigations or tests. MSHA shall hold as confidential and shall not

tests of the unit or system as it deems appropriate. The conduct of all
investigations, tests, and demonstrations shall be under the direction and
control of MSHA, and any other persons shall be present only as observers,
except as noted in paragraph (b) of this section.
(b) When requested by MSHA, the applicant shall provide assistance in
disassembling parts for inspection, preparing parts for testing, and
operating combination units.
