===[[File:AirAlarm.png]] Repressurization and Filtering ===
After the [[Engineer]]s have taken care of a hull breach (read: if), or after [[Toxins]] floods the place with plasma, it'll be your job to refill the area and make it breathable.

This can be done by using the Atmosphere Alarms mounted in most areas, along with the vents and scrubbers in the area.

The primary utility of the Atmosphere Alarm in refilling an area involves the vents. 
Each vent has a pressure check value on it, and is by default set to pressure check '''externally''' - this means that the vent attempts to bring the tile it's on to the listed pressure.
A rapid manner of refilling an area is to remove the external pressure check, switch it over to the internal check - this attempts to regulate the pressure in the pipes of and running to the vent below, which is directly fed by the distribution loop pump in the north end of Atmosia. 
Setting the "pressure bound" variable to zero with internal pressure checks attempts to void all air in the pipes, effectively reducing their pressure to zero and, in the process, flooding air at an alarming rate into the area. Given the impractically slow rate at which the air alarms normally fill the area, this can be a very expeditious way to work. Pressure is dangerous, so don't simply leave the vent alone for extended periods of time, as you can, eventually, turn smaller areas into death-traps if there is enough pressure in the distribution loop.

The alarms can be set to a number of modes:

* '''Filtering''' - The default setting. Note that most scrubbers won't filter out plasma or other gases unless you set them to, so do that!
* '''Draught''' - This filters out air slowly, creating a draught. Useful if you need to drain a small amount of air due to overpressurization.
* '''Panic''' - This drains all the air quickly. Most of the time used to remove all plasma very quickly, or by a malfunctioning AI.
* '''Replace Air''' - Drains all the air, then replaces it. Try not to use it if there's nothing toxic in the air.

Normally the vents will fill the room slowly by default, though using some filled Portable Air Pumps, or Air Canisters you can refill the area much more quickly.
