What you Can do to Pass the Time

Atmos Techs usually have no clue what they can do, and often drift into a spiral of depression and suicide. Fret not! Here are some suggestions for you to do.

AirAlarm.pngRepressurization and Filtering

After the Engineers have taken care of a hull breach (read: if), or after Toxins floods the place with deadly phoron, 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. This may also be done remotely from the Engineering monitoring room, which is highly recommended if possible.

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 "Internal Target" 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 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.

To unlock the alarm, either swipe your ID card on it, or simply ALT click the panel while your card is in the ID slot. Remember to lock them when you're done with them to prevent unwanted tampering!

The alarms can be set to a number of modes:

  • Filtering - The default setting. Note that most scrubbers won't filter out phoron or other gases unless you set them to, so do that!
  • Replace Air - Drains all the air while replacing it. Try not to use it if there's nothing toxic in the air.
  • Panic - Drains all the air quickly. Most of the time used to remove all phoron very quickly, or by a malfunctioning AI.
  • Cycle - This siphons all the air out, then, when there is none in the atmosphere, turns the Fill mode on.
  • Fill - Turns off all the scrubbers in the area. Useful for refilling breached areas.

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


A fire is easily the most fun thing that can happen in a round (for you anyway); successful firefighting requires a real understanding of the atmospheric system. At all times, wear basic tools in a toolbelt and carry your firefighting gear in your backpack. When the call goes out, don your fire suit and gas mask, get yourself running on internals, put your oxygen tank on your back, and carry your fire first aid kit, extinguisher and reinforced glass in your backpack (carried in a hand slot).

Use this!

Drag a water tank behind you and get to the fire. With AI cooperation, have the burning area bolted or welded off, save one access point the AI can monitor. This keeps the fire from spreading and chucklefucks from wandering into a fiery doom. Once inside, you must quickly determine the sort of fire you are dealing with. Pressure tanks of phoron can release massive amounts of fuel (or even burst!) and must be shut off or isolated immediately, while the best way to isolate broken pipes is to box them in with reinforced glass until a proper repair can be done. With fuel shut off, find the atmospheric alarm and set it to Panic Siphon.

This drains air out of the room completely. With this process started, check for survivors or bodies and remove them from the compartment via your access point. Next, seek out any ignition sources such as lit Zippo lighters and disable them, reporting them to security for their forensic investigation. Then proceed with extinguishing any remaining pockets of flame. Once the fire is out focus on clearing any remaining phoron from the atmosphere by dragging in a scrubber.

Finally, set the atmosphere alarm to pump in fresh air. It may take several cycles of filling and draining the room to clear all phoron and make larger areas inhabitable again, but once you are done, head to the bar and rest in peace knowing the Engineers will be the ones to clean up the mess.

(Note: this lengthy guide is only really useful for those big "Research done herped-a-derp" fires that engulf Med/Sci or are caused by very skillful arsonists. Smaller fires, such as the sort chemists who just learned the napalm recipe cause, really only require some fire-extinguisher blasts and setting up a room's scrubber to remove phoron and CO2. Never presume, however, that you won't need your full toolkit. This author spent well-nigh an hour in the fiery bowels of med-sci on one occasion, but not only did I never have to leave after I stepped in and sealed it off, but I had the situation so well under control that after five minutes normal shipboard life resumed and admins eventually had to spawn facehuggers to return a sense of danger to the crew.)

FireAxe.pngTotal Emergency: The Fire Axe and you

Can be found here.

The Fire Axe is your tool during emergencies: you can use it like a crowbar to open doors when the power is off, you can break full reinforced windows in one hit, and it even has great hacking potential as in, you can hack at the door until it breaks and then open it. The fire axe is protected with a fire axe cabinet. To open it, use a multitool that is lying somewhere around and hack it open. There is also the option of just hitting at the cabinet until it breaks, but what kind of barbarian would do that?

ReinforcedWindowGrilled.png Window Repair

A good way to be proactive within your job is fixing the broken windows that occur every round. Gird your loins with a toolbelt if you can, grab some metal and glass, and patrol the outer passageways. Almost always, the task requires a low-pressure or no-pressure exposure to the great beyond. By creatively rotating and moving surviving windows you can lock in your precious atmosphere, then replace the broken glass and grille. The truly insane technicians do minor spacewalks with only the flame of their welding torch for heat, sipping sweet oxygen through their breath masks behind a welding helmet. While that might prove positively lethal, if the situation calls for it this could be done, disregarding your internal organs being fried with unhealthy doses of solar radiation and other pleasantries of space.

Laying Some Pipe

Both machines look like this.

You have two machines! One Machine is for for gas pipes, and one for disposal pipes. To install gas pipes, simply click on them in your hand until they are properly aligned, drop them on the tile they are needed, and use the wrench on them. For disposal pipes, one must drag them into position, wrench them in place on the subfloor, then weld them to seal it all together. You can also unwrench those machines and reinstall them at wherever need be and, even if this is somewhat bulky, it is still a more elegant and sane solution to the problem than hauling all the pipes around in your backpack or a locker.

Oxygen is Overrated

Traitor atmos techs have the potential to become one of the most devastating forces on station. If you know what you're doing, you can pretty much flood the station with whatever harmful gas you want. If you do, remember to take measures against the AI messing with your work, and always keep your internals on. This means either subverting the AI or cutting its access. If you're feeling particularly daring, you can unwrench the pipes and rearrange them, ensuring the AI cannot fix it. Bolt the doors, or set the room on fire to prevent humans from fixing it too. Depending on how bad it's going to be, you might want to procure a space suit to escape the hell you've created.
