SPECIFICATION 6
Specifications of Magazines
- General:
The basic
considerations in the construction of magazines are security to ensure that the contents
are kept out of the hands of unauthorised persons; to maintain them in good conditions and
to reduce the risk of accidental explosion. This calls for a construction, which will
resist illegal entry as much as possible and is well ventilated. In choosing a site for a
magazine, consideration should be given to any protection of life and property offered by
natural features of the ground in the event of a fire and/or an explosion. The suitability
of a site and the amount of explosives that may be stored are determined by its distance
from public thoroughfares; residential or industrial areas, railways etc. as specified in
the table of safety distance in Schedule VIII. Naturally a site obscured from public view
either by natural or artificial means is preferred.
Apart from
the Rules and Regulations concerning the storage of explosives certain conditions should
be observed from the point of view of care for the materials concerned e.g. improper
storage may lead directly to misfires later on. In all cases, places of storage should be
dry, well ventilated and protected from extremes of temperature as much as possible.
Stocks should be drawn upon in strict rotation any surplus from the days work being
returned to the magazine and kept separately for use on the following day.
Safety Fuse
and detonators should be kept in perfect condition for obtaining good results. Therefore,
at all times during transport, handling and storage, they should be protected from
moisture and contact with oil, grease, kerosene or other liquids. Detonators shall not be
stored with other explosives.
- Types of Magazine:
Magazines
may be of heavy construction, i.e. steel , reinforced concrete, brick, stone or preformed
concrete blocks. Maximum security is attainable only with steel or reinforced concrete
structures. The internal dimensions of the magazine shall be such that there is ready
access to all explosives.
- Construction of the Magazine:
A magazine
shall be well and substantially and shall be made and close so as to prevent unauthorised
persons from having access thereto and to secure it from danger.
MODE A MAGAZINE

volume). Reinforcement should consist of square mesh, hard-drawn steel wire fabric,
providing a cross-section area in each direction of not les than 0.21in 2 ft of wall. The
reinforcement shall be covered by not less than 50 mm of concrete on either side. The

Commercial grade steel is satisfactory for use in construction. The cement mortar shall
consist of not less than one part of cement and three parts of clean sand.
- have interior, and the benches, shelves and fittings therein
so constructed or so lined or covered as to prevent the exposure of any iron or steel and
the detaching of grit, iron, steel or similar substances in such manner as to come into
contact with explosives. Such interior benches shelves and fittings shall be kept free
from grit and otherwise clean; and in the case of any explosive that is liable to the
dangerously affected by water due precautions shall be taken to exclude it therefrom.
- have roof reinforced concrete at least 150 mm thick.
- have one ventilator at the top and bottom in each opposite
side wall of the magazine where the weight of explosive stored is upto and including 500
kgs and minimum two in the top and bottom of each wall where the weight of explosive
stored exceeds 500 kgs. Number of the ventilators may be increased as desired by the
licensing authority. The ventilators shall be 22.5 cm x 11.25 cm. Z type fitted with frame
of iron bars set firmly in the wall on the outer face, the bars to be of 2.35 cm2
, (3/8" sq.) iron set anglewise with the frame. The inner opening to be protected
with brass wire gauge of 3 mesh per centimeter.
- have external doors
- that opens outwards and when closed fit tightly;
- to be constructed of steel plate at least 5mm, thick with or
without internal lining of wood
f. have every internal door
- made of wood;

changing of clothe and shoes.
k. have 25 x 50 mm furring strips fastened to the wall, vertically on 300 mm centres
starting 130 mm from floor and
continuous to the stacking line, around the usable portions of the walls to provide air
circulation and to prevent
cases of explosives being stacked directly against the walls.
l. have a minimum 12 mm red line painted on the interior walls of the magazine at a
height of 2.5 metres from the

SPECIFICATION 7
SPECIFICATION OF A STOREHOUSE
The basic consideration in construction of a storehouse are to ensure that the contents
are kept out of the hands of unauthorised persons, to maintain them in good condition and
to reduce risk of fire. This calls for a construction which will resist illegal entry as
much as possible and is well ventilated. The place of a storage should be dry and it
should be possible to draw stocks in strict rotation.
The storehouse should have walls built of brick, stone or concrete. The bricks and
concrete shall conform to relevant Indian Standard Specifications. The cement mortar shall
consist of not less than one part of cement and three parts of clean sands. The interior
of the storehouse shall be kept clean and all benches, shelves and fittings shall be so
constructed or so lined or covered as to prevent the exposure of any iron or steel and the
detachment of any grit, iron, steel or substances steel or substances in such manner as to
come in contact with the materials stored and such interior, benches, shelves and fittings
shall as far as is practicable be kept clean and free from gift. The storehouse shall have
adequate number of ventilators as desired by the licensing authority. The ventilators
shall be provided at the top and the bottom of the walls as suggested by the licensing
authority. The ventilators shall be 22.5 cm x 11.25 cm fitted with suitable frames firmly
set in the walls on the outer face. The bars to be of minimum 2.35 cm2 set

from the floor level. This line indicates maximum height to which explosives may be
stacked. The gang way space of minimum 30 Cm shall be provided around the usable portion
of the walls to provide air circulation. In addition sufficient space shall be provided
for passage between the stacks of packages if required by the licensing authority. The
licensing authority may specify lower stacking height if deemed necessary.
The storehouse shall have sufficient number of wooden windows for proper lighting inside.
The windows shall open outwards. The storehouse shall have smooth, stone or cement
flooring.
