Environment in Submarine Compartments

The crew operating in the confined environment of a submarine are subjected to discomfort as a result of physiological stress caused by toxic substances which are generated due to engineering, operational and other human activities. The physioiogical problems of men under prolonged confinement in a submarine have been reviewed. Data on air pollutants monitored during 'cruise' and 'at rest' conditions inside a submarine are given. Threshold limit value (TLV) of trace substances in the confined environment has been discussed. The merits of air purification and air revitalization systems currently employed for control of air pollution have been brought out
