restrictions
Sec. 1. (a) Separate surface magazines shall be provided for the
storage of explosives, detonators, and blasting heater elements.
(b) Surface magazines for storing and distributing explosives in
amounts exceeding one hundred twenty-five (125) pounds shall be
as follows:
(1) Reasonably bulletproof and constructed of incombustible
material or covered with fire-resistant material. The roofs of
magazines so located that it is impossible to fire bullets directly
through the roof from the ground need not be bulletproof, but
where it is possible to fire bullets directly through them, roofs
shall be made bullet-resistant by material construction, or by a
ceiling that forms a tray containing not less than a four (4) inch
thickness of sand, or by other methods.
(2) Provided with doors constructed of three-eighths (3/8) inch
steel plate lined with a two (2) inch thickness of wood, or the
equivalent.
(3) Provided with dry floors made of wood or other nonsparking
material and have no metal exposed inside the magazine.
(4) Provided with suitable warning signs so located that a bullet
passing directly through the face of a sign will not strike the
magazine.
(5) Provided with properly screened ventilators.
(6) Equipped with no openings except for entrance and
ventilation.
(7) Kept locked securely when unattended.
(c) Surface magazines for storing detonators need not be
bulletproof, but they shall be in accordance with other provisions for
storing explosives.
(d) Explosives in amounts of one hundred twenty-five (125)
pounds or less or five thousand (5,000) detonators or less shall be
stored in accordance with preceding standards or in separate locked
box-type magazines. Box-type magazines may also be used as
distributing magazines when quantities do not exceed those
mentioned. Box-type magazines shall be constructed strongly of two
(2) inch hardwood or the equivalent. Metal magazines shall be lined
with nonsparking material. No magazine shall be placed in a building
containing oil, grease, gasoline, waste paper, or other highly
flammable material, nor shall a magazine be placed less than twenty
(20) feet from a stove, furnace, open fire, or flame.
(e) The location of magazine shall not be less than two hundred
(200) feet from any mine opening, occupied building, or public road.
Where compliance with this provision is not practicable, the
magazine shall be effectively barricaded.
(f) The supply kept in distribution magazines shall be limited to
approximately one (1) day's requirements, and such supplies of
explosives and detonators may be distributed from the same
magazine, if separated by at least a four (4) inch substantially
fastened hardwood partition or the equivalent.
(g) The area surrounding magazines for not less than twenty-five
(25) feet in all directions shall be kept free of rubbish, dry grass, or
other materials of a combustible nature.
(h) If the explosives magazine is illuminated electrically, the
lamps shall be of vapor-proof type, installed and wired so as to
present minimum fire and contact hazards.
(i) Only nonmetallic tools shall be used for opening wooden
containers. Extraneous materials shall not be stored in an explosives,
detonator, or blasting heater-element magazine.
(j) Smoking, carrying smokers' articles, or open flame shall be
prohibited in or near any magazine.
(k) Cardox may not be used in an underground mine.
