Build:Basic Life Support
5.5 Basic Life Support
(Required)
Cost: 4 x Size
Basic life support is the standard environmental and breathable gases systems which all starships must have (this includes the ability to adapt some living quarters for non-Class M environments). Multiple independent safety locks and redundant systems ensure that it is very difficult to disable such systems.
A ship’s breathable atmosphere is conducted throughout the vessel by a network of ventilation ducts; larger ships have two (or more) independent networks. Starfleet standards specifiy that all ships must have two primary atmospheric processing units for every fifty cubic meters of habitable volume. Other life support systems maintain the temperature and humidity aboard ship.
If basic life support is cut off, reserve and/or emergency systems activate. If all systems were somehow disabled, a starship has enough breathable atmosphere for a period equal to Size x 3 in minutes. After that, vessel inhabitants suffer damage as if they were drowning.
