(11) Vessel's fire-fighting equipment, both fixed (where installed) and portable, in vicinity of space being worked shall be kept ready for immediate use. (f) Refueling. (1) Trucks using gasoline as fuel may be refueled in the hold or on the weather deck of a vessel only when such refueling is done with an acceptable portable non-spilling fuel handling system of not over 5 gallons capacity. Transfer of gasoline to these portable non-spilling fuel handling devices is not permitted on board the vessel. (2) Power-operated industrial trucks using liquefied petroleum gas as fuel may be refueled in the hold or on the weather deck of a vessel only when fitted with removable tanks and provided the handoperated shut-off valve of the depleted tank is closed and the engine is run until it stalls from lack of fuel before the quick disconnect fitting is opened. In addition, the quick disconnect fitting shall be attached to the fuel tank before the hand-operated shut-off valve is reopened. (3) Power-operated industrial trucks using diesel oil as fuel may be refueled on the weather deck or in the hold of a vessel by means of portable containers of not over 5-gallon capacity. These trucks may also be refueled on the weather deck of a vessel or portable containers refilled from a larger container provided a suitable pump is used for the transfer operation and a drip pan of adequate size is supplied. (4) Refueling shall be under the direct supervision of an experienced and responsible person specifically designated for such job by the person in charge of the loading or unloading of the vessel. (5) No refueling shall be undertaken with less than 2 persons specifically assigned and present for the complete operation, at least one of whom shall be experienced in using the portable fire extinguishers required in the fueling area. (6) At least one approved 4-pound dry chemical hand portable fire extinguisher, or its approved equivalent shall be provided at the scene of the fueling area. This is in addition to portable extinguisher affixed to the truck in accordance with paragraph (e) (10) of this section. (7) The location for refueling trucks shall be designated by the master or senior deck officer on board the vessel. "No Smoking" signs shall be posted in the area and smoking shall be prohibited. (8) The location designated for refueling shall be adequately ventilated so as to insure against accumulation of a hazardous concentration of vapors. The ventilation requirements of paragraph (e) (3) of this section when trucks are operating shall also apply when trucks are being refueled. (9) Truck engines of all trucks in the same hold shall be stopped before any truck in that hold is refueled and before any fuel handling devices or unmounted liquefied petroleum gas cylinders are placed in the hold. (10) All fuel handling devices and unmounted liquefied petroleum gas containers shall be removed from the hold before any truck engine is started and the trucks again placed in operation. (g) Replacing batteries. Batteries for electrically powered industrial trucks and for the ignition systems of internal combustion engine-powered industrial trucks may be changed in the hold of a vessel provided the following conditions are met: (1) Suitable handling equipment shall be employed. (2) Adequate precautions shall be taken to avoid damage to the battery, short circuiting of the battery, and spillage of the electrolyte. (h) Charging of batteries. Batteries of electrically powered industrial trucks may be recharged in a hold of a vessel provided the following conditions are met: (1) The batteries shall be housed in a suitable, ventilated, portable metal container with a suitable outlet at the top for connection of a portable air hose, or shall be placed directly beneath a suitable metal hood with a suitable outlet at the top for connection of a portable air hose. The air hose shall be permanently connected to an exhaust duct leading to the open deck and terminate in a goose neck or other suitable weather head. If natural ventilation is not practicable or adequate, mechanical means of exhaust shall be employed in conjunction with the duct. The air outlet on the battery container shall be equipped with an interlock switch so arranged that the changing of the battery cannot take place unless the air hose is properly connected to the box. (2) If mechanical ventilation is used, an additional interlock shall be provided between the fan and the charging circuit so that the fan must be in operation in order to complete the charging circuit for operation. It is preferable that this interlock switch be of a centrifugal type driven by the fan shaft. (3) The hold shall not contain any cargo coming under the regulations prescribed in this subchapter. (4) The charging facilities may be part of the truck equipment or may be separate from the truck and located inside or outside the cargo hold. The supply or charging circuit (whichever method is used) shall be connected to the truck by a portable plug connection of the break-away type. This portable plug shall be so engaged with the truck battery charging outlet that any movement of the truck away from the charging station will break the connection between the plug and receptacle without exposing any live parts to contact with a conducting surface or object, and without the plug falling to the deck where it may become subject to injury. (5) All unmounted batteries shall be suitably protected or removed from an area in the hold of the vessel before trucks are operated in that area. (i) Stowage of power-operated industrial trucks aboard a vessel. (1) Poweroperated industrial trucks may be stowed in any location aboard a vessel provided the following conditions are met: (i) Gasoline powered trucks shall have all the fuel expended from the system. (ii) Liquefied petroleum gas powered trucks shall have the fuel tanks removed and all the fuel expended from the system. (2) Power-operated industrial trucks not meeting the conditions set forth in subparagraph (1) of this paragraph shall be stowed on the open deck except for intervals such as lunch hours, between work shifts, interdock and intraport movements. If stowed in a fixed metal enclosure located on or above the weather deck, such enclosure shall have access from the weather deck only and shall have adequate ventilation, so arranged as to remove vapors from both the upper and lower portions of the space. (j) Stowage of fuel handling devices aboard a vessel. (1) Flammable liquids and gases to be used as fuels for poweroperated industrial trucks shall be marked, labeled and stowed as follows: (i) They shall be stowed in ICC specification containers, A.S.M.E. containers or portable safety containers having the approval of a recognized testing laboratory, which containers are authorized for the contents. (ii) Containers shall be marked with the name of the contents and shall be labeled in accordance with ICC requirements as follows: or, (a) Flammable liquids-"Red Label"; (b) Flammable Label." gases "Red Gas (iii) Containers shall be stowed on or above the weather deck in locations designated by the master. ICC specification containers, A.S.M.E. containers, or portable safety containers having the approval of a recognized testing laboratory may be stowed below the weather deck in a paint or lamp locker provided such containers do not exceed 5 gallons capacity each. (2) Diesel fuel shall be stowed in locations designated by the master.

AD Hull constructed of steel or wood, completely decked over, fitted with cargo hatches, with or without superstructure house covering the deck, and capable of stowing cargo “On deck” or "On deck within the house” or “Under deck”, having holds that are not ceiled. BA Hull constructed of steel or wood with partial deck at ends and/or sides, fitted with hatches with or without coaming and having ceiled holds and loading cargo "Under deck" only. BB Hull constructed of steel or wood with partial deck at ends and/or sides, with open ceiled hold or holds. L BC Hull constructed of steel or wood with partial deck at ends and/or sides, with or without hatches and having hold or holds without ceiling. Class "C" Barges CA Hull constructed of steel or wood, completely decked over and stowing cargo “On deck in open" only, fitted with cargo mast and boom, and machinery for cargo handling, with or without house or houses on deck.

Class "D" Barges DA Hull constructed of steel having division bulkheads forming tight compartments (tanks) integral with the hull of the barge, to be utilized for the transportation, in bulk, of dangerous substances in liquid form, other than inflammable and combustible liquids. DB Hull constructed of wood having division bulkheads and ceiling forming tight compartments integral with the hull of the barge, to be utilized for the transportation, in bulk, of dangerous substances other than liquids.
