Section 139. Physical examination of employed minors; cancellation of employment certificate

1. A medical  inspector  of  the  department  of
  labor shall require any minor sixteen or seventeen years of age employed
  in or in connection with any trade, business, or service, to submit to a
  physical  examination by him if in his judgment such minor is physically
  unfit for the work at which he is employed. The result shall be recorded
  on a form filed with the commissioner.
    2. If such minor  fails  to  submit  to  such  examination  or  if  on
  examination  the  inspector  finds  the  minor physically unfit to be so
  employed, he shall so  report  to  the  commissioner  with  his  reasons
  therefor  and  the  commissioner,  if he approves the report, shall then
  cause the employment certificate issued in accordance with the education
  law to be taken from the office of the employer  and  shall  return  the
  same to the superintendent of schools recommending its cancellation.
