Any party in interest may be permitted to examine the record of the
case in which he is interested. The official custodian of the record
sought to be inspected shall permit or deny inspection in accordance
with the Department of Labor's regulations pertaining thereto (see 29
CFR part 70). The original record in any such case shall not be removed
from the office of the custodian for such inspection. The custodian may,
in his discretion, deny inspection of any record or part thereof which
is of a character specified in 5 U.S.C. 552(b) if in his opinion such
inspection may result in damage, harm, or harassment to the beneficiary
or to any other person. For special provisions concerning release of
information regarding injured employees undergoing vocational
rehabilitation, see Sec. 702.508.
