NOTE:
(1) X-indicates that thickness of screening cargo is sufficient without any additional segregation distance.
(2) By using 6 feet of intervening unit density cargo for persons and 10 feet for film and plates, no distance shielding is necessary for any length of voyage specified.
(3) Using 1 steel bulkhead or steel deck-multiply segregation distance by 0.8. Using 2 steel bulkheads or steel decks-multiply segregation distance by 0.64.
(4) "Cargo of Unit Density" means cargo stowed at a density of 1 ton (long) per 36 cubic feet; where the density is less than this the depth of cargo specified must be increased in proportion.
(5) "Minimum distance" means the least in any direction whether vertical or horizontal from the outer surface of the nearest package.
(6) The figures below the double line of the table shall be used in those cases where the appropriate provisions of this class permit the sum of the transport indices to exceed 200.
(7) Not to be carried unless screening by other cargo and bulkheads can be arranged in accordance with the other columns.
