All corrosive liquids permitted for transportation on board vessels shall, if taken on board a vessel, be stowed in accordance with the provisions applying to the particular character of vessel as shown in the tables forming § 146.23-100 and with the detailed regulations for stowage. [CGFR 52-41, 17 FB. 10348, Nov. 13, 1952] § 146.23-10 General stowage require ments. In the stowage of corrosive liquids, the following conditions shall be observed: (a) Corrosive liquids shall be stowed well away from living quarters, foodstuffs or cargo of an organic nature. (b) Stowage shall be in such manner that the containers may be readily observed. (c) Corrosive liquids shall not be stowed over any combustible substance even though such substance is not dangerous by the regulations in this part. [CGFR 59-14, 24 FR. 5274, June 30, 1959] § 146.23-13 Use of power-operated industrial trucks in spaces containing corrosive liquids.

The transportation of acids and other corrosive liquids in glass carboys on board barges is not subject to this provision. The term "completely boxed carboys" may include regularly boxed carboys with neck protection extending to the sides of the carboy box; or of crate construction; either type to be of strength commensurate with the strength of the carboy box itself and to be sufficiently adequate to permit stacking one on top of the other. [CGFR 52-41, 17 F.R. 10848, Nov. 18, 1952] (a) Acids, alkaline caustic liquids, and other corrosive liquids permitted to be stowed "On deck" shall be so stowed that any leakage from a container will drain away from other cargo and readily reach an overboard scupper or freeing port. Such drainage shall not be permitted to enter an enclosed drainage system other than a direct overboard scupper. If such stowage is not possible to arrange, clean, hard, dry sand shall be placed under and around the lower tier of containers to absorb any leakage. (b) Dunnage shall be provided on the deck and otherwise and so arranged that any appreciable leakage will be apparent. (c) Any leakage occurring shall be washed down, using liberal quantities of water. [CGFR 52-41, 17 FR. 10848, Nov. 18, 1952] § 146.23-25 Stowage of corrosive liquids with explosives and other dangerous articles. The stowage of corrosive liquids with explosives and other dangerous articles shall conform to the following conditions: (a) Corrosive liquids shall not be stowed "Under deck" on a vessel carrying Class A or Class B explosives unless one complete hatch or the engine and boiler room spaces intervene, nor "On deck" on a vessel carrying Class A or Class B explosives unless the engine and boiler room spaces or the bridge structural erection intervene. (b) Corrosive liquids shall not be stowed in the same hold or compartment with Class C explosives. (c) Corrosive liquids shall not be stowed in the same hold or compartment with inflammable liquids. (d) Corrosive liquids shall not be stowed in the same hold or compartment with inflammable solids. (e) Corrosive liquids shall not be stowed in the same hold or compartment with oxidizing materials. (f) Corrosive liquids shall not be stowed adjacent to or over cylinders of compressed gases. (g) Corrosive liquids shall not be stowed adjacent to or over containers of poisonous articles. (h) Corrosive liquids shall not be stowed adjacent to or over containers of hazardous articles. (i) Corrosive liquids shall not be stowed in the hold or compartment over one in which cotton is stowed unless the deck is of steel and the hatch is fitted with a tight coaming and the deck itself is tight against leakage. Corrosive liquids shall not be stowed over the square of the hatch. (j) Corrosive liquids shall not be stowed in the same hold or compartment with radioactive materials.

(b) Such limited quantity shipments may be accepted on board all vessels subject to the regulations in this part provided the bill of lading or other shipping paper correctly describes the article in accordance with the true name as shown in the commodity list. Stowage shall be "On deck under cover" or "Tween decks" in a compartment not subject to artificial heat.
