There are many things that can kill the average spessman in ss13. Most of those can be prevented by having security stop them. But some threats can only be solved by two people: Engineering, and you personally (yes you!). Those are the ones that will be discussed today. This guide is about how to handle plasma fires (and how to prevent them).
“Only YOU can prevent station fires” 
Stopping disasters before they even start
The most common accidental cause of fires is messing up toxins, closely followed by atmos setups and the SM. Being careful doesn’t just mean not acting stupid here. It also means taking the extra step and actively making precautions to prevent a fire at all costs. Remember to double check if the airlocks truly are closed, or build a second wall around your setup just for safety’s sake.
It’s also, and maybe even more important, to prevent intentional fires aswell. Do not let anyone into toxins or the SM room without a good reason, I have seen so many plasmafloods that could have been prevented by just asking the guy why he wanted access to that room. Monitor them closely while inside, and do not be afraid to kick them out if they seem suspicious. Half the time they’re griefers anyways, so this is generally just a good idea.
“Dear god help me it hurts” 
Dealing with yourself being on fire
So you are on fire. You followed all the warning from the previous section, and still nothing worked. But do not worry spessman! Because that isn’t quite the end of your NT owned life yet. The best tip to dealing with fires is to extinguish, and not drop and roll.
Yes you heard that right, those anti slime guns actually have another purpose besides dealing with the creations from xenobio. Fire extinguishers are all around the station and you can easily find one before you drop into crit. Ontop of that, dropping and rolling doesn’t always work in curbing the fire and can even make everything worse by wasting precious time. If you are a miner or lavaland spawn, carry around an extinguisher, because dropping during a lava fire won’t work at all!
It is also important to take distance from anyone else while burning, becausing touching them means you’ll spread the fire! (Unless you WANT that to happen, of course)
“We didn’t start the fire” 
Dealing with hot rooms
Do not open doors to hot rooms. I will repat this again: Do. NOT. Open. Doors. To hot rooms. This is probably the worst thing you could do and will make a fire that was previously contained in a small room spread everywhere and make it way harder to control. Always, ALWAYS, use holobarriers if you absolutely need to enter them.
Sometimes there are no atmos techs present to cool down the air. In that case, you can try doing basic firefighting by deconstructing the floor and spacing the room. Most of the time this is the only effective way to deal with it, since siphoning and using space heaters does next to nothing. Then use an air tank (which you can find in emergency storage) to replace the atmosphere with cool and fresh O2.
With these tips in mind, next time you might be able to save your limbs before turning to a crisp!
