Engineering overview

You are the Station Engineer, everything that breaks is supposed to be fixed by you. You get a lot of useful tools to fix various things on the station. A good engineer responds to emergencies promptly and repairs things fast so the rest of the crew can go on with their life.

Tools and equipment

You spawn with a full toolbelt. Almost everything can be manipulated with one of these tools. If you are in doubt what to use, try the crowbar!
Insulated gloves are a must have to avoid electric shocks. There are a couple scattered around in Engineering and more in the electrical supplies locker. Cargo can order more. Working without these can be harmful or even fatal!
A Multitool is useful to manipulate wires of every kind. You also find this in the electrical supplies locker.
A Welding mask is essential for welding if you want to keep your eyesight. You find these in the welding supplies locker. Also grab an Industrial welding tool and replace the one in your belt with that.
The maintenance tunnels are dark. A good engineer always has a Flashlight on him.
You also need a Meson scanner. Never look into the singularity without these! It also makes you able to see hull breaches through walls. Scientists can hook you up with an advanced version that doesn't require lights to work. Available from the engineer's locker or the YouTool vending machine.
Hazard vest. This doesn't do much but you can put your oxygen tank in it's storage slot so you can use your other slots for tools. Get it from racks or from engineer's locker.
Engineering hardsuit. This is a must have if you plan to go into space for some reason. Since there is only two of these provided in the suit storage units, make sure to only take them if you really need them. Walking around in a hardsuit just in case is considered powergaming and also annoys other engineers who might actually need the suit. The hardsuits provide decent but not total protection from radiation.
Radiation suit. Available from the radiation suit closets. You need this if you have to work near a Radiation collector array or the Particle accelerator while the singularity is active.
