Individual CO2 Absorbent Canisters
In case of a possible escape from an submarine, every member of the crew
has been provided with a canister of CO2 absorbent, fitted with an ori-nasal
mask and mouthpiece and noseclip, the necessary oxygen content of the
vessel’s air being maintained by a supply delivered automatically into
the submarine’s compartments. If it became necessary to leave the vessel
while submerged, the men discarded the canister and put on their escape
apparatus.
