Take a look at this guy
for an easy example. I take a motion sensor on the warp sled, and turn off all of the thrusters whenever anyone is in the cockpit, standing up. So I dont cook myself 
I also take the same idea in the cv farm in that collection, and give a kill switch to manuall turn off all thrusters and RCS either on motion inside, or when the killswitch is activated. That way fuel in the farm lasts as long as possible.
