If any trailer or semitrailer subject to the periodic safety inspections required by this article is equipped with a heating or cooking appliance, the safety inspection of such trailer or semitrailer shall include a visual inspection of the venting of such cooking or heating appliance to the outside of the trailer or semitrailer. No safety inspection approval sticker shall be issued to any such trailer or semitrailer unless any such heating or cooking appliance is adequately vented to prevent the asphyxiation of occupants of any such trailer or semitrailer by the operation of the heating or cooking appliance.
