  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
