(1) Packages of explosive materials shall be laid flat with top side up. Corresponding grades and brands shall be stored together in such a manner that brands and grade marks show. All stocks shall be stored so as to be easily counted and checked. Packages of explosives shall be stacked in a stable manner. When any kind of explosive is removed from a magazine for use, the oldest of that particular kind shall always be taken first.

(2) Packages of explosives requiring impact or potentially spark producing methods to open or to close shall not be opened or closed in a magazine, nor within 50 feet of a magazine or in close proximity to other explosive materials.

Only Type I permittees experienced in the destruction of explosive materials shall be allowed to do the work of destroying explosives.

(8) When magazines need inside repairs, all explosives shall be removed 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 in order for repair shall either be placed in another class appropriate 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.

(9) Explosive materials within a magazine are not to be placed against the interior walls and must be stored so as not to interfere with ventilation when required.

This inspection need not be an inventory, but must be sufficient to determine whether there has been unauthorized entry or attempted entry into the magazine, or unauthorized removal of the contents.

(11) Flammables, such as the liquid components of binary products, shall not be stored with other explosives.

(J) Lighting Within Magazines

(1) Battery-activated safety lights or battery-activated safety lanterns may be used in explosives storage magazines.
