Working on an unusual project. Its a training structure for the fire department made from storage containers, no electrical, plumbing, or insulation. Its essentially a metal box stacked together with doors and windows so they can set mock fire scenarios for training. My question is, does the building code still apply even if its not designed for life/safety of the occupant? For example, if the intent is exiting the 2nd floor through a window instead of a door, can I ignore the number of doors required by code?
