What you do is rather simple, if there is any sort of environmental disaster, head off and fix it! You have your tools, your engineering headset, pipe, space heaters, and atmospheric survival equipment. When things get quiet, sit back and start building an on ship super slide.

Bare minimum requirements: Fight fires, restore the atmosphere in rooms that can't support life. Know how to fix sabotage to Atmospherics.

Atmospherics

The great city state of pipes, it is used as a jet pack recharge station for Syndicate Agents, a hide out for Wizards, a breeding ground of Xenos, and has a general alert computer that will tell if any place is messed up.

Considering how often rooms get blown up when the shields fail, this place will be important to restoring air.

Important Note about some FTL13 ships

The Atmospherics pipes required to actually refill a room are disconnected at roundstart, making it impossible for the air to actually come through the vent pumps. This may be a bug, however for now it is advisable to find a connection from an air mix to the vents, otherwise a breach will forever stay depressurized, and that's not good for your crew. (Confirmed on Aetherwhisp, 05/06/2017)

Repressurization and Filtering

After the Engineers 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. Much like how low pressure is dangerous, too much pressure is just as 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!
Contaminated - This triples scrubber efficiency, quickly removing all contaminants set to be filtered in the scrubbers menu.
Draught - This filters out air slowly, creating a draught. Useful if you need to drain a small amount of air due to overpressurization.
Refill - This triples the output on the vents, useful for pressurizing an important area quickly.
Cycle - This will drain the air from a room, then replace it. Not useful for most situations unless there is absolutely no breathable air.
Siphon - This will drain the air from a room, without replacing it. Good for making somewhere dangerous to be without a suit.
Panic Siphon - This drains all the air three times as fast. Most of the time used to remove a plasma-ridden room's air 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.

At roundstart and normally, Air alarms will be set to Filtering, which will repressurize an area, and scrub out any contaminants (CO2 only by default!).

Guide to Firefighting

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).

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 a Ship Engineer from wandering into a fiery doom. Once inside, you must quickly determine the sort of fire you are dealing with. Pressure tanks of plasma 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 Syphon.

This drains air out of the room completely. With this process started, check for survivors or bodies and either apply burn patches and epinephrine or simply 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 plasma 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 plasma and make larger areas inhabitable again, but once you are done, head to the bar and score some babes while Engineers 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 plasma 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.)

Total Emergency: The Fire Axe and you

The Fire Axe is your tool during emergencies (because you can use it like a crowbar to open door when the power is off) and your weapon (traitors, revolutionaries and cultists usually try to steal the axe because you can kill a person in seconds). The fire axe is protected with a Fire Axe Cabinet. To open it, just take a welding tool, turn it on and hit the fire axe cabinet a lot of times and take the axe. You can also use a multitool to hack it open, but who does that?

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 grill. The truly hardcore 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. Are you hardcore? No, you're not. Go back to being a hardsuited engiqueer who can't find a hull breach without a pair of mesons and never bothers to fix them anyway.

Life Sucks and Blows

You can purge the air of of rooms using an emergency siphon, or change the air filter controls by deal with the air alarm attached to walls! Just take your ID in hand, and click to un/lock it and play with the controls. Setting up the pumps in Atmos now allows you to pump any gas to any point in the ship!

Protip: Pure oxygen lets people survive in a breached compartment much longer.

Protip: Pure oxygen makes plasma fires much, much worse.

Protip: Since you're in charge of both breathing and firefighting, Murphy's Law says you're screwed.

Laying Some Pipe

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. A personal locker makes a great method to haul all the air pipes you'd ever need between job sites, but disposal pipes must be dragged one at a time. Expect Security to frequently and irrationally demand the locker be checked for bodies, usually three or four times a minute, if you use the main hallways.

Tips

Firesuits protect between 60 to 30,000 kelvin.
Setting air vents to 0 kPa internal check (or just turning off the check) will make them pump out air like crazy, which makes it excellent to restore air to an area quickly. But be careful with the pressure on the vent tile itself, if the pressure in the outgoing distro loop is very high it might be dangerous. ADDED: Don't max the vents. Set the vents to internal and desired pressure 0 instead. Maxed vents at 5000 KPA in a 100 KPA room will output 2450 KPA in the first tick, then 1225 KPA, 612.5 KPA, 306.25 KPA, 153.125 KPA, etc etc (assuming vents are always provided with max air). Zero'd vents will output 5000 KPA, then 5000 KPA, then 5000 KPA, etc.
N2O knocks out in low amounts, suffocates in high amounts.
If you're an atmos tech trying to repair a hull breach without a fire/space suit: Turn off the vents. No more air will be vented into the room, which means there won't be any space wind to fight against if you accidentally fall out the window.
Atmos tech is actually an interesting job, disposal tubes give such wonderful opportunities for killing people, however it takes shitton of time to build everything you need.
Any sort of air mix is survivable as long as it has at least 16 kPa of oxygen on the output. This means you can easily compute the release pressure you'd need for a given airmix by dividing 16 by the percentage of oxygen in the mix; i.e. for 20/80 O2/N2 air mix you'd need a release pressure of 16/0.2 = 80 to be fine.
Steps To Set Up Atmospherics So You Never Need To Worry And It Fucking Helps You Out

Turn off and unwrench Air to Distro and Waste In, two pumps in the northern area of Atmos where the distro loop and mixing is done and all that. They are labeled and easy to find. Keep them in place on the floor.
Go to the atmos pipe dispenser a few meters away, and vend two volumetric pumps. These are like regular pumps but almost literally better in every way whatsoever. They pump more, faster.
Fit your volumetric pumps in place of Waste In and Air to Distro, making sure the red stripe lines up with how the pumps were fitted by default so the flow goes the right way.
Volumetric pumps are automatically set to full fucking power so just turn on both of them.
Set every scrubber in the loop around the room to 4500 kPa. This is full blast.:* You have now completely set up Atmospherics to be beast mode in, like, three minutes. You can also do other stuff, like fit manual valves to the bad gasses to hamper solo-AI floods, and replace other pumps in the bowels of Atmospherics with volume pumps, but really, that five point checklist will do it. Ninety-plus percent of people don't know jack shit about Atmospherics, and it's so easy to set it up so that it actually does shit. It's so rare to see it happen that the CE actually sought me out for praise for doing it this way.:* For AIs, if no organics are around competent/willing to do this manually and your Engiborgs (if you have any) are busy, which is like a guarantee, you can do a simpler version of this; just turn Air to Distro and Waste In up to 4500 kPa and set each scrubber station to 4500 kPa too. It won't be as effective but it's so much better than nothing. Cranking up the air available in the distro loop poses no threat to safety, and in fact makes it harder to start up harmful floods since there's so much good air in the way in there. And since you're the AI, you can now use air vents (and scrubbers) as they were fucking designed to be used; to scrub, drain, and replace air in rooms as necessary, and it fucking works. It is astonishing how little is required to turn a system so often seen as worthless into a helpful part of the ship.:* Minor addendum: A maxed volume pump and a maxed normal pump pump at the same rate given ideal circumstances. The difference is the volume pump won't stop pumping once its output end is at 4500 kpa or more. This makes it excellent for waste in, where no matter how much gas the previous fire/atmos experiment clogged the filtering loop with, Waste In is still pumping waste out of the scrubbers pipes, and by extension, helping keep the scrubbers from getting clogged to the point of uselessness.:* For the record, the advice of adding manual valves to the plasma loop will result in you getting yelled at by an admin if there's no evidence that the AI is rogue. It's "Spacing objectives tier", and for good reason.:* Setting up atmos doesn't really matter that much anyway as long as you give the distro loop some pressure. The entire supply and equipment is designed for a space ship that's supposed to last month. There's about two instances in which a proper setup is useful: massive hullbreaches which will drain a lot of air (most of which will then uselessly disappear in space anyway) and ship wide plasma fires which might fill the waste loop (in which case you're at fault as an atmos tech for not keeping an eye on the system in the first place).

If you are an atmos tech and want to greatly reduce possibility of harmful atmos manipulations... or if you are an AI and you spotted a guy just turning valves to release plasma to distro:

Open atmospherics console for specific chamber and toggle power on output. 90% of players don't check this console. As AI I laughed many times as sabotagist was running back and forth, checking every pump 3 times, and still no plasma appeared. In this way you can also shut down harmful gases pumping when one is smart and changed pipes under grilles.:* Or put manual valves in front of every harmful gas, switch out some gas pumps for volumetric pumps, and repipe the mixing pipes to disallow the mix tank to provide into the distro. (Setting up Atmos in such a way it can't be sabotaged by the AI before there's a reason to think the AI might sabotage Atmos is not only metagaming, it is also bannable. If you see this happen, adminhelp it!)

You can rotate a pipe in your hand by click on it.
Fire extinguishers fit in firesuit suitstorage.
The Fire Axe Cabinet can be opened with a multitool.
You can disable fire alarms by multitooling them.
You can trigger fire alarms by shooting them with a projectile. ADDED: Or hitting them with anything.

Tips for Traitoring

The incinerator can easily be used to create canisters of pure death.
Plasma + N2O is extremely deadly if you can get someone to use it as internals/force them to use it. They won't even be able to scream.
Wielded fire-axes break grilles and reinforced windows. In one shot.
- And open unpowered doors and kill people fairly reliably.
You can change sensor settings on air alarms so it doesn't cause an alarm by setting the value to -1, which turns that sensor off. Do it for all sensors and you can get rid of pesky alarms that are pretty much already fixed, or hide atmos fuckery.

Oxygen is Overrated

Traitor atmos techs have the potential to become one of the most devastating forces on the ship. If you know what you're doing, you can pretty much flood the ship 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.
