§ 146.29-43 Requirement for the opening of hatches.

(a) Vessels at explosives loading piers or at ammunition loading piers. (1) A weather deck hatch through which ammunition or explosives are being worked shall have sufficient hatch covers and hatch bearns removed across the entire width of the hatch so that the resulting opening, measured parallel to the side of the vessel, is at least equal to twice the longest axis of the largest draft being loaded.

(2) Strongbacks or hatch beams left in place shall be firmly secured by hatch batten or other approved means.

(b) Vessels at explosives anchorages. A weather deck hatch through which ammunition or explosives are being worked shall have all hatch covers and all hatch beams removed unless otherwise authorized by the Captain of the Port.

(c) Vessels at explosives anchorages having a magazine constructed in the square of a weather deck hatch. Sufficient hatch covers and hatch beams shall be removed from the weather deck hatch to expose the entire magazine.

(d) General requirements. (1) During the working of ammunition and explosives to or from the deep holds, the 'tween-deck hatch openings shall at all times be equal to, if not greater than, the weather deck hatch openings.

(2) The use of open hooks in removing or replacing hatch beams or hatch strongbacks is prohibited. Closed hooks, shackles or T bars shall be used in this operation.

§ 146.29-45 Loading or unloading military explosives and other cargo.

(a) Military explosives shall not be loaded or unloaded in a hatch at the same time that other cargo is being worked in any of the holds serviced through said hatch.

(b) Military explosives shall not be loaded or unloaded from the same hatch from both sides of the ship simultaneously, unless the hatch is fitted with cargo handling gear located at both the forward and after ends of the hatch. A vessel so equipped may also use both sets of cargo handling gear simultaneously from the same side of the vessel.

(c) When military explosives are stowed in a hold below one in which any cargo is being worked the 'tweendeck hatch dividing the two holds will have all of its covers securely in place. (d) Military explosives may be loaded in a hold before or after other cargo, provided that all precautions are taken to assure full protection to the explosives against the hazard of articles being dropped from the cargo sling. When possible hatches should be partially covered to assure such protection.

(e) Drafts of any kind shall not be handled over explosives or other dangerous articles that are stowed "On deck".

(f) Any deck loads over which military explosives must be passed shall be limited in height to that of the hatch coaming, bulwark, or three feet, whichever is greater.

(Sec. 1, 49 Stat. 1889, 46 U.S.C. 391a) [CGFR 62-11, 27 FR 5287, June 5, 1962, as amended by CGFR 69-72, 34 FR 17494, Oct. 29, 1969; CGD 71-12a, 37 FR 14586, July 21, 1972]

§ 146.29-47 Packing and marking.

Military explosives shall not be offered to vessels or accepted by vessels subject to the regulations in this part unless they are in proper condition for transportation

and are packed, marked, labeled, described, certified and otherwise acceptable in accordance with the applicable provisions of the regulations in this part.

§ 146.29-49 Stowage on board barges.

(a) Barges subject to the regulations in this part, engaged in the transfer of explosives between receiving points and delivery points within the har

bors, bays, sounds, lakes, and rivers, including the explosives anchorages on the navigable waters, shall conform to the applicable provisions of 49 CFR 176.95 through 176.99. Ammunition or explosives in bulk, in combustible outside packages, stowed "On deck in open" shall after loading and during transportation be covered by fire resistant and/or flame proof tarpaulins securely lashed in place.

(b) Notwithstanding the requirements of this subpart relative to the stowage of detonators, blasting caps and fuzes, Class VIII, such articles may be stowed "On deck" on Class 1A and Class AB barges with other ammunition or explosives in bulk stowed thereon, provided a sandbag barrier of at least 2 feet in thickness intervenes between the ammunition or explosives in bulk and the detonators, blasting caps or fuzes. When both are stowed "On deck" the height of this barrier shall be at least equal to the height of the stowage of the detonators, blasting caps or fuzes, or the ammunition or explosives in bulk, whichever is highest. The barrier shall either completely surround the detonators, blasting caps or fuzes or extend across the width of the barge. With this type of barrier no additional separation is required. For Class AC barges, the stowage of detonators, blasting caps or fuzes, Class VIII, shall, when no permanent steel bulkhead intervenes, be separated from the stowage of ammunition or explosives in bulk by a distance of 40 feet; with a permanent steel bulkhead intervening, detorators, blasting caps or fuzes shall be separated from the stowage of explosives in bulk by a distance of 25 feet and from the stowage of ammunition by a distance of 10 feet. If, under deck, a 2-foot sandbag barrier is utilized to intervene between the stowage of ammunition or explosives in bulk, it shall be considered as though a permanent steel bulkhead or deck intervenes. Notwithstanding the provisions of 49 CFR 176.98, Class CA and Class CB barges may transport ammunition on deck.

§ 146.29-57 "On deck" stowage.

(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.

(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, containers or cargo transporters 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 containers shall be in accordance with 88 146.29-99 and 146.29-100. A deck box, portable magazine, container or cargo transporter containing military explosives shall be separated from other deck boxes, portable magazines, containers or cargo transporter containing 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, sounding pipes and access ways shall be maintained free and clear.
