This is the forum for Movie and Film discussions. Again, our topic is naval warfare in WWII for the most part.

"Boomers" and "fast attack" boats permit smoking while submerged, unless an
evolution requires that the "Smoking Lamp" be extinguished in a certain compart-
ment or throughout the boat. These boats have methods of "cleaning" the atmosphere of the boat, such as CO2 (carbon dioxide) scrubbers, electrostatic precipitators mounted on the reduction gear housing vents, to prevent the oil fog from entering the boat's atmosphere, and a large one outside the galley to remove the methane gas generated by cooking food. Human waste creates methane gas also, and when the sanitary tanks are blown and vented inboard, the "odor" passes through granulated charcoal ffilters. Methane is flammable.. CO (carbon monoxide) passes through "burners" and back into the ventilation system. Hydrogen from the ship's battery evolves upon discharging and charging, and hydrogen ventilation blowers evacuate the gas andd keep the explosive content under 4%; it becomes very dangerous if a concentration over 4% occurs.
The pharmacist's mate ("Doc") monitors the atmosphere of the boat, as far as CO2
and Oxygen is concerned. When the oxygen content in the boat is too low, he
bleeds some into the boat, and this is one of the evolutions where the smoking lamp is extinguished. If the both CO2 scrubbers are OOC, he spreads lithium hydroxide (absorbent) on mattress-tops in the berthing quarters until repairs are made to the scrubbers.
The dewpoint is constantly controlled at 50% and the ambient temperature is about 68 degrees Fahrenheit at all times. Therefore, tobacco smoke is of little
consequence compared to smoke from cooking meals. The rarified atmosphere inside a modern air-conditioned submarine is conducive to accomplishing all the
scheduled tasks and routines of a patrol.
Hope this answers you question,
