Ariz. Admin. Code § 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. Containers 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 constructed 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-sparking 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
disposed of properly. Stained magazine floors shall be cleaned according to
instruction obtained from the explosives manufacturer. 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 instructions obtained from the
manufacturer. Only experienced persons 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 magazine 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 detonating
cord.
