From the nature of submarine operations, itis very necessary to the comfort, health and safety of the crew that the inter-ior of thp boat be at all times kept as free as possible, especially while charg-ing, from all battery fumes and gases, and with present stage of the art it. Pig. 112.—Suction System of Ventilation as Applied to Open Type Cell Installation. may be said that the suction system of ventilation is superior to the pressuresystem for this service, inasmuch as when using the suction system the pres-sure in the cells is less than that of the interior of the boat, hence, the batterygases are accordingly prevented from escaping into the boat. When operat-ing submerged, however, the air is usually exhausted from the ventilationsystem directly into the interior of the boat, but at such time the batteriesare either discharging or are standing idle, and as has been previously pointedout, there is relatively little gas evolved from the cells during these periods,and in consequence there is little objection to exhausting the air of the ven-tilation system into the interior of the boat.
