Space Station - Emergency Bunker

A typical space station emergency survival bunker. These are placed through out a space station's interior, especially around habitats, and other major gathering areas. They are designed to automatically seal themselves after a set period of time should the station sustain catastrophic damage, such as loss of atmosphere, etc. They are capable of sustaining their occupants at full capacity, for 7 to 10 days, longer if not fully occupied, and feature independent power, waste, and atmosphere systems. In the case of minor damage, or a toxic release, they can be used to shelter in place, in which case they are able to draw power and life support from the main station systems if available.
