Section R11-1-237. Storage within magazines

A.       Containers of explosives shall be laid flat with top side up. Corresponding grades and brands shall be stored together in such a manner that brand and grade marks show. All stocks shall be stored so as to be easily counted and checked. Con- tainers of explosives shall be piled in a stable manner. When any kind of explosive is removed from a magazine for use, the oldest explosive of that particular kind shall be removed first.

B.       Only fiberboard containers of explosives may be opened in a magazine. Opened containers of explosives shall be securely reclosed when stored in a magazine.

C.       Tools used for opening containers of explosives shall be con- structed of non-sparking materials, except that metal slitters may be used for opening fiberboard containers. A wood wedge and fiber, rubber, or wood mallet shall be used for opening or closing wood containers of explosives.

D.       Magazines shall be used for the storage of explosives, blasting agents, and oxidizers only. Metal tools, other than non-spark- ing transfer conveyors, shall not be stored in a magazine.

E.       Magazine floors shall be regularly swept, kept clean, dry, free of grit, paper, empty used packages, and rubbish. Brooms and other cleaning equipment shall not have any spark-producing metal parts. Sweepings from floors of magazines shall be dis- posed of properly. Stained magazine floors shall be cleaned according to instruction obtained from the explosives manu- facturer. When any explosive has deteriorated to an extent that it is in a dangerous condition, or if liquid leaks from any explosive, then the person in possession of such explosive shall destroy such explosive in accordance with the instruc- tions obtained from the manufacturer. Only experienced per- sons shall direct the work of destroying explosives.

F.       When magazines need 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 in another magazine or placed a safe distance from the maga- zine where they shall be properly guarded and protected until repairs have been completed, when they shall be returned to the magazine.

G.      Ammonium nitrate fuel oil blasting agents shall be physically separated from other explosives, safety fuse, or detonating cord stored in the same magazine, in such a manner that oil does not contaminate the other explosives, safety fuse or deto- nating cord.
