WRONG, many times you could and do end up staying up all shift. A working firehall could never be compared to home.
You check equipment, train on the equipment, and maintain the fire hall. You then eat when you can, sleep if you get a chance(some nights are better than others) and many guys try and workout to maintain the physical skills required for the job. Now in between the activities above add in 10-20 calls for medical, Fire, car accidents, rescues, false alarms and even a cat up a tree (it happens).
Would I trade this job for anything else....NEVER!
