(g) Any person storing explosive materials shall open and inspect his magazines at least every seven days. This inspection need not be an inventory, but shall be sufficient to determine whether there has been unauthorized removal of their contents.

(l) Containers of explosive materials shall be stored by being laid flat with top sides up. Corresponding classes as defined in 40 CFR Part 173, grades, and brands of explosives shall be stored together within a magazine in such a manner that grade, brand, and USDOT class marks are easily visible upon inspection. Stocks of explosive materials shall be stored so as to be easily counted and checked.

(m) Except with respect to fiberboard or other nonmetal containers, containers of explosive materials shall not be unpacked or repacked inside a magazine or within 50 feet of a magazine, and shall not be unpacked or repacked near other explosive materials. Containers of explosives materials shall be securely closed while being stored.

(n) Tools used for opening or closing containers of explosive materials shall be of nonsparking materials, except that metal slitters may be used for opening fiberboard containers.
