No temporary building shall be erected where it will adversely affect any means of exit.
Temporary buildings, when located within another building or structure, shall be of either noncombustible construction or of combustible construction having a fire resistance of not less than 1 hour.

Material shall be piled to minimize the spread of fire internally and to permit convenient access for firefighting. Stable piling shall be maintained at all times. Aisle space shall be maintained to safely accommodate the widest vehicle that may be used within the building for firefighting purposes.
Clearance of at least 36 inches shall be maintained between the top level of the stored material and the sprinkler deflectors.
Clearance shall be maintained around lights and heating units to prevent ignition of combustible materials.
A clearance of 24 inches shall be maintained around the path of travel of fire doors unless a barricade is provided, in which case no clearance is needed. Material shall not be stored within 36 inches of a fire door opening.
