For example, in a submarine during surface cruising, fresh air is drawn down across hatches to ventilate the ship and provide new supply for the engines. As a result, the large quantities of air, which pass through several compartments, produce strong currents of air in the vessel. The problem of ventilation in a submarine necessitates fire fighting, if called for, under circumstances much different than fighting land fires where the first act is to clear away the products of combustion by providing proper ventilation.
