CONSTRUCTION STANDARDS FOR TYPE I MAGAZINES

(1) General: These magazines shall be bullet-resistant, weather-resistant, fire-resistant and also resistant to forcible entry by thieves and attack by saboteurs, and be constructed as follows:

(2) Wood-frame walls:

(a) These walls shall be of the following type: an open framework, consisting of 2 by 6 in studs, continuous along their full height placed on 16 in centres and covered on both sides with plywood panels, as described in b and c, so as to form a space 6 in wide, to be filled with dust-free hard stone crushed to a diameter of less than 1/4 in or any other material which can significantly reduce penetration by bullets and which, in the case of an explosion, is not likely to constitute a hazard by being propelled any distance.

(b) The outer sheathing of the wall shall include, first, a layer of plywood of a minimum thickness of 1/2 in to which will be firmly stapled a 5/16 in, 18 gauge, expanded steel mesh followed by another layer of plywood panel also of a minimum thickness of 1/2 in, the joints to alternate with those of the first. The metal mesh is not to be cut at the ventilation openings and is to cover them without a break; it is to be bent at least 16 in around each corner. The exterior wall shall be completely clad with 20 gauge galvanized iron, overlapping by at least 2 in at the joints and 4 in at the corners.

(c) The inner sheathing of the wall shall consist of at least one layer of plywood 3/4 in thick.

(d) The ventilators shall be either S-shaped, 4 in in diameter with the lower opening on the outside, or, straight-through, not larger than 6 in by 6 in protected on the outside by a steel plate 1/2 in thick, not more than 3 in from the wall and forming a hood. Inside they shall be equipped with a second 5/16 in, 18 gauge, expanded steel mesh and, in addition, a screen to prevent objects from being inserted into the magazine.

(3) Floors:

(a) For permanent magazines:

i. a 4 in thick concrete slab, poured over 4 in of gravel, with an additional concrete topping 3/4 in thick;

ii. solid wood at least 4 in thick covered with plywood 3/4 in thick with the good side up. This type of floor shall be laid on a base of concrete, stones or concrete blocks. If columns or posts are used, leaving a crawl-space beneath the floor, 5/16 in, 18 gauge, expanded steel mesh shall be placed between the 3/4 in thick plywood and the sub-flooring. In this case, a 5/16 in, 18 gauge, expanded steel mesh shall close off access to the crawl-space.

(b) For mobile magazines: solid wood at least 4 in thick covered with the 5/16 in, 18 gauge, expanded steel mesh, followed by 3/4 in thick plywood with the good side up.

(4) Roofs:

(a) roofs shall be well fitted and fastened to walls by means of anchor bolts;

(b) roofs may be built in any one of the following ways:

i. one layer of 2 in thick, tongued and grooved lumber, followed by 5/16 in, 18 gauge, expanded steel mesh and then by a layer of plywood of 1/2 in minimum thickness, all to be covered with 24 gauge, or thicker, galvanized iron, or else, with asbestos roofing material in accordance with current practice so as to be adequately weather-resistant and fire-resistant;

ii. 2 layers of roofing plywood 3/4 in thick, sandwiching 5/16 in, 18 gauge, expanded steel mesh, all covered as indicated in subparagraph i;

(c) whenever it is possible to shoot directly through a roof and hit the explosives stored, there shall be fixed to the ceiling a sort of wooden plate covered with polythene and filled with stone crushed to 1/4 in (or mortar containing 10% cement), at least 4 in thick.

(5) Door frames and sills: Door frames and sills shall consist of 2 angle-irons 4 in by 4 in and 1/4 in thick, continuously welded and firmly held to the frame by means of flat headed bolts. The doorstop shall consist of angle-iron one by one, by 1/4 in, welded along the whole frame.

(6) Door: The door shall be a hanging door consisting of 2 steel plates 1/4 in thick firmly riveted and welded along the edges, sandwiching a sheet of pressed asbestos at least 1/4 in thick and finally an inner facing of plywood 3/4 in thick affixed with contact cement. Such a door shall be solidly fixed on hinges such as CMT 5 x 5 for jails, or the equivalent, so that once it is closed, there remains not more than 1/16 in clearance between the door and the frames or the sills. In addition, the inner face of such a door, on the side of the hinges, shall be fitted with not less than 3 fixed locking bolts consisting of 3 lugs of at least a 3/4 in2 section, welded on the edge of each door at regular intervals and protruding enough the block the latter, once it is closed, by fitting into recesses in the framework.

(7) Locking devices: The hanging door shall be equipped with 2 maximum security, independent, anti-theft, mortise locks with individual keys which cannot be duplicated except by the manufacturer, only after identification and signature, or alternatively with any other approved locking system guaranteed to give equal or better security.

R.R.Q., 1981, c. E-22, r. 1, Sch. 2.

N.B. Already-existing concrete block structures shall be protected either by a steel cladding at least 1/8 in thick, and all seams continuously welded or by a 1/2 in, 16 gauge or thicker, expanded steel mesh on the entire surface of the walls, covered by 3 layers of stucco each not less than 1/4 in thick.
