a. It shall be
  the duty of the commissioner to make suitable  regulations  under  which
  the  officers and members of the department shall be required to wear an
  appropriate uniform and badge by which the authority  and  relations  of
  the   officers  and  members  in  such  department  may  be  known.  The
  commissioner shall select the grade of cloth and  quality  required  for
  such  uniforms, but shall not prescribe where or from whom such uniforms
  or uniform clothing  shall  be  purchased,  or  the  price  to  be  paid
  therefor.  It  shall be unlawful for any contractor or agent or employee
  of any contractor for the making of uniforms for the department to  have
  an  office  within any building belonging to or under the control of the
  department.
    b. It shall be a misdemeanor, punishable by imprisonment for a  period
  of  not  less than sixty days, for a person not enrolled or employed, or
  appointed by the department, to wear  the  whole  or  any  part  of  the
  uniform or insignia prescribed to be worn by the rules or regulations of
  the  department,  or to do any act as firefighter not duly authorized by
  the commissioner, or to interfere with the property or apparatus of  the
  department  in  any  manner unless by the authority of the commissioner.
  Any person who shall falsely represent any member of the uniformed force
  of the department, or who shall maliciously,  with  intent  to  deceive,
  use,  or imitate any of the signs, fire caps, badges, signals or devices
  adopted or  used  by  the  department,  shall  be  deemed  guilty  of  a
  misdemeanor  and shall be subject to a fine of not less than twenty-five
  dollars or more than two hundred fifty dollars, and to imprisonment  for
  a  term  of not less than ten days, or more than three months, such fine
