When magazines are in need of inside repairs, all explosives shall be removed therefrom and the floors cleaned. In making outside repairs, if there is a possibility of causing sparks or fire the explosives shall be removed from the magazine. Explosives removed from a magazine, under repair, shall either be placed within another magazine or placed a safe distance from the magazine where they shall be properly guarded and protected until repairs have been completed, at which time they shall be returned to the magazine.
