(f) Inflammable liquids in drums or in export wooden cases having inside containers in excess of one quart capacity shall not be stowed as beam fillers. Wooden barrels, wooden boxes, and fiberboard boxes with inside containers of inflammable liquids of less than one quart capacity shall not be stowed as beam fillers unless it is possible to stow and observe "This Side Up" markings. (CGFR 51-19, 16 F. R. 7219, July 24, 1951, as amended by CGFR 55–20, 20 F. R. 4058, June 10, 1955)

$ 146.21-35 Boundary bulkheads. Holds, with bulkheads in which cargo openings to adjacent holds are fitted, shall not be used for the stowage of inflammable liquids unless such openings are provided with means to securely close off and make the hold gas tight or unless the adjacent hold is also used for the stowage of inflammable or combustible liquid cargo.

$ 146.21-40 Hatch closing means. All unit compartments or holds used for the stowage of inflammable liq shall be provided with full and efficient hatch covers. Tarpaulins if fitted or required to be fitted shall be protected by dunnaging before overstowing with cargo. Such tarpaulins shall be in one piece and free of rents, tears, or holes. § 146.21-45 Ventilation.

All cargo holds in which inflammable liquids are to be stowed and which are provided with means for ventilating shall, before any inflammable liquid cargo in a quantity in excess of 1 ton be stowed in such hold, have fire screens fitted at the weather end of the vent ducts. This fire screen shall consist of two layers of fine brass wire screen of at least a 20 x 20 mesh spaced not less than 12 inch or more than 11/2 inches apart. This screen may be removable, and if so fitted, means for

effectively securing the same in place when in service shall be provided. Mushroom type heads shall have similar fire screens so fitted as to completely and efficiently cover the open area. For holds that are gas tight and fitted with vent trunks such vent trunks may be eficiently blanked off at both termini in lieu of fitting flame screens. Stowage of inflammable liquids in a quantity in excess of 1 ton shall not be permitted in holds or compartments that are fitted with gooseneck type of vent trunk heads.

$ 146.21-50 Electrical equipment in holds. Inflammable liquids shall not be stowed in holds or compartments in which electrical apparatus of any type except vapor proof are fitted unless positive means for disconnecting all such electrical apparatus are provided and such control means are located outside the boundaries of said space. Electrical power lines passing through a hold that is to be used for the stowage of inflammable liquids shall have such run of cable protected by metal covering to prevent damage and possible short circuit. Such metal protection shall be substantial enough to prevent crushing by reason of cargo which might be stowed against same.

$ 146.21-55 Smoking prohibited, warning signs. (a) Smoking prohibited in the vicinity of inflammable liquid cargo stowed "On deck" and in holds in which such cargo is stowed or in the vicinity of ventilators from such holds.

(b) Signs carrying the legend

Inflammable Vapors Keep Lights and Fire Away

No Smoking

shall be posted at each avenue of approach to inflammable liquid cargo when stowed “On deck” and in the vicinity of cargo hold ventilators when inflammable cargo is stowed in the höld. Such sign shall be painted on a white background using a bright red color for lettering. The letters shall not be less than 3 inches high.

$ 146.21–60 Potable spirits. Potable spirits packed in strong, tight barrels, drums, casks, wooden or fiberboard boxes may, when stowed in a compartment not

or

subject to artificial heat, be transported on board any vessel without further restriction.
