(a) Articles classified as military explosives, the stowage of which is permitted "On deck" by the regulations in this subpart shall be properly secured. Such security may be obtained by using existing vessel's structures such as bulwarks, hatch coamings, shelter deck and poop bulkheads, as part boundaries and effectively closing in the cargo by fitting angle bar closing means, secured by bolting to clips or other parts of the ship's structure. Lashing of deck stowage permitted provided eye pads are fitted to carry such lashings. Guard rails shall not be used to secure such lashings.

(b) Bulky articles may be secured by lashing with individual wire rope lashing or other equally efficient means.

(c) Shoring of such bulky articles of cargo shall be in addition to the foregoing means of securing.

(d) Military explosives stowed "On deck" shall not be stowed within a distance of 20 feet of an incinerator, the topside terminus of an ash hoist or a coal or oil fire galley or bake shop. For vessels fitted with electrically operated galleys and bake shops, the military explosives stowed on deck may be stowed not closer than 10 feet of such galleys and bake shop provided no incinerator or topside terminus ash hoist is within a distance of 20 feet of such stowage.

(e) Deck boxes, portable magazines, cargo transporters or vans containing military explosives shall meet the requirements of this section when stowed "On deck." Compatibility of the explosives within the deck box, portable magazine, cargo transporters or van shall be in accordance with § 146.29-99 and

§ 146.29-100. A deck box, portable magazine, cargo transporter or van containing permitted military explosives shall be separated from other deck boxes, portable magazines, cargo transporters or vans containing permitted explosives of incompatible classes by the superstructure or, if the height of the container does not exceed that of the hatch coaming, by the weather deck hatch. Fire plugs and sounding pipes and access ways shall be maintained free and clear. [CGFR 62-11, 27 F.R. 5287, June 5, 1962, as amended by CGFR 67-23, 32 F.R. 8158, June 7, 1967]

§ 146.29-63 Stowage and dunnaging of ammunition and containers of explosives in bulk.

(a) Military explosives shall be so stowed and dunnaged as to prevent damage to the cargo or the vessel from shifting cargo caused by forces incident to the voyage of the vessel. Nothing within this paragraph shall be construed as requiring the entire interior of the cargo compartment to be covered with dun

nage.

(b) Containers of military explosives marked, "This side up" or otherwise marked directing their stowage shall be so stowed.

(c) Kegs of black powder shall be stowed in an upright position, the bungs or other filling openings "up". Each tier shall be floored off.

(d) Metal containers or metal tanks or other containers of propellant charges having closure means which protrude beyond the chime or the surface of the container shall be so dunnaged as to prevent damage occurring to such closures.

(e) The uppermost tier of military explosives shall be so secured to the mutual satisfaction of the Captain of the Port and the Master of the vessel by tomming, bracing, strapping, top stowing with permissible cargo of sufficient unit weight and quantity or other effective means that no displacement can occur either upwardly or laterally.

(f) Military explosives shall be so stowed that they or the containers are not liable to be pierced by the dunnaging or crushed by superimposed weight.

(g) Containers of military explosives shall not be "cant" stowed. They shall be stowed in full bearing on dunnage or both end and center bearing on dunnage. Broken stowage may at the turn of the bilge, be dunnaged out with cordwood or otherwise so cribbed as to provide maximum bearing attainable for the container to be stowed in the tier above. Broken stowage in other locations in the hold may be compensated for by cribbing out or by the insertion of sufcient dunnage to provide proper bearing for packages in the tier above.

(h) Fixed or semifixed ammunition in fiber containers, crated or uncrated, may be stowed on its base or on its side. Dunnaging shall be accomplished in such manner as to bear only upon the metal part of the container. No dunnage or weight shall bear directly upon the fiber portion of the container.

(1) [Reserved]

(j) Separate-loading projectiles, boxed, crated, unboxed, or uncrated may be stowed on their bases or on their sides except as otherwise provided for Army WP filled ammunition in the stowage requirements for Class II-D ammunition, 146.29-100.
