(a) Magazines shall be located in a hold, preferably a tween deck hold that is dry and well ventilated. They shall be so located as not to be in horizontal proximity to crew or passenger accommodations nor below such living spaces. Magazines shall not be built on or under the principal bridge or other navigation spaces. The hold or compartment in which a magazine is constructed shall provide a positive closing means to prevent all traffic through the area after the explosives are stowed, except ingress and egress for inspection purposes. con (b) Magazines shall not be structed in bearing with the collision bulkhead, nor with a bulkhead forming a boiler room, engine room, coal bunker or galley boundary. If it is necessary to construct a magazine in proximity to these bulkheads a cofferdam space of at least one foot shall be provided between the permanent bulkhead and the magazine bulkhead. This cofferdam space shall remain open to the free circulation of air and shall not be used for stowage or storage purposes. (c) When a magazine is to be constructed over a tween deck hatch, the hatch girders or strongbacks and the hatch covers forming the tween deck hatch shall be of such design and size as to insure their carrying the imposed load with safety. Covers of the tween deck and over deck hatch shall completely close the hatch opening and fit securely in place. Tween deck hatch covers of wood forming the base of the magazine shall be completely covered with asbestos board at least 1/4 inch thick, fitted tight at the sides of the magazine, the joints of the asbestos board being staggered midway between joints formed by the wooden hatch covers. Magazines shall be constructed in accordance with the applicable provisions of § 146.09-2, except floor shall be formed by dunnaging over the asbestos board. In the construction of a magazine care should be taken that no metal structural parts protrude within the magazine. If it is proposed to carry the stowage of explosives up into the over deck hatch coaming, this coaming shall be sheathed with wood. A magazine located in the hatchway may be so constructed as to occupy only a part of the area of the hatchway. Portable magazines may be stowed in the square of the hatchway and either lashed or tommed to prevent movement. (d) Construction and location of magazines for stowage of explosives other than as provided in this subpart or as provided in § 146.20-15 shall be authorized by the Commandant of the Coast Guard.

Metal stanchions within the magazine shall be boxed with wood of a thickness of not less than 34-inch. When steel decks or tank tops are utilized to form the floor of a magazine, a wooden floor of not less than 11⁄4-inch commerical lumber, constructed on bearers shall be fitted. Such floor may be portable but tight to prevent movement. (c) Magazines constructed of wood shall have the bulkheads forming the sides and ends constructed of commercial 1-inch lumber, of 3/4-inch tongue and groove sheathing, or of 3⁄44-inch plywood, secured to uprights of at least a 3- by 4-inch size, spaced not more than 18 inches apart and secured at top, bottom and center with horizontal bracing. When 34-inch plywood is used, the uprights may be spaced on 24-inch centers. Uprights shall not be stepped directly onto a metal deck. A 2- by 4-inch bearer to carry the uprights shall be laid upon the metal deck. A 2- by 4-inch header shall be fitted against the underside of an overhead deck to receive the top of uprights. Top of uprights fitted against channel beams may be wedged directly to the beam with 2- by 4-inch spacers fitted between. Care shall be taken in securing upright framing that no nails penetrate to the interior of the magazine. When a magazine is constructed as a permanent compartment in the vessel, increased size and finish of lumber and other methods of fastening may be used provided such fastenings are recessed below the surface of the boarding to avoid projections within the interior of the magazine. All boardings shall be fitted and finished so as to form a smooth surface within the interior of the magazine. Construction shall be such as to separate all containers of explosives from contact with metal surfaces of the structure of the vessel. When a metal stanchion, post or other obstruction is located within the interior area of the magazine, such obstruction must be completely covered with wood of a thickness of at least 34-inch secured in place with nails or screws. All screws or nails used in the magazine for fastening shall be countersunk below the surface of the wood.
