Inspection of trailers and semitrailers will include a visual inspection of the venting of cooking or heating appliances to the outside of the trailer or semitrailer to determine if the heating and cooking appliances are adequately vented to the outside to prevent the asphyxiation of occupants of any trailer or semitrailer by the operation of the heating or cooking appliances.
