Looking at the commentary and pictures in the handbook,
Is the equipment 6 feet wide? if so;
I read it that if you can't run straight away from the panel (south door in your case) you either need double working space or 2 doors.
The bottom line is, would you be able to get out of there with all your hair if there was fire shooting 3 feet out of that panel. I'm sure your shorts would be a goner in any case
