3.1 Special air ducts

 Combustion engines require large volumes of atmospheric air. Therefore, most engine-rooms are provided with overpressure in relation to the accommodation. To reduce the overpressure and, thereby, the risk of harmful vapours entering the accommodation, special air-ducts could be fitted to the air intake for combustion engines and boilers.
