49 C.F.R. Subpart N—Detailed Requirements for Class 8 (Corrosive Materials) Materials
Title 49 - Transportation
Source: Amdt. 176–30, 55 FR 52708, Dec. 21, 1990, unless otherwise noted.
(a) Each package required to have a Class 8 (corrosive) label thereon being transported on a vessel must be stowed clear of living quarters, and away from foodstuffs and cargo of an organic nature. (b) A package of Class 8 (corrosive material) material may not be stowed over any readily combustible material. (c) Glass carboys containing Class 8 (corrosive material) material may not be stowed on board any vessel, other than a barge, more than two tiers high unless each carboy is boxed or crated with neck protection extending to the sides of the carboy box. This protective construction must be strong enough to permit stacking one on top of the other. (d) A Class 8 (corrosive material) material may not be stowed over a hold or compartment containing cotton unless the deck is of steel and the hatch is fitted with a tight coaming. In addition, the deck must be tight against leakage and the Class 8 (corrosive material) material may not be stowed over the square of the hatch. (e) Each package of Class 8 (corrosive material) which also bears a FLAMMABLE LIQUID label must be stowed away from all sources of heat and ignition. [Amdt. 176–30, 55 FR 52708, Dec. 21, 1990, as amended by Amdt. 176–39, 61 FR 18933, Apr. 29, 1996] When break bulk Class 8 (corrosive materials) materials being transported on a vessel are stowed on deck: (a) Provisions must be made for leakage from any package to drain away from other cargo into an overboard scupper or freeing port. The drainage may not enter an enclosed drainage system other than a direct overboard scupper. If this stowage is not practical, sufficient clean dry sand must be placed under and around the lower tier of packages to absorb any leakage. (b) Dunnage must be provided on the deck and arranged so that any leakage will be apparent. (c) Any leakage that occurs must be washed down, using liberal quantities of water.
