(a) Each material listed in Table 148.10 of this part must be segregated from incompatible materials in accordance with--
(1) The requirements of Tables 148.120A and 148.120B of this section that pertain to the primary or subsidiary hazard class to which the materials belong. Whenever a subsidiary hazard may exist, the most stringent segregation requirement applies; and
(2) Any specific requirements in Subpart D of this part.
(b) Materials that are required to be separated during stowage must not be handled at the same time. Any residue from a material must be removed before a material required to be separated from it is loaded.
(c) Definitions and application of segregation terms:
(1) ``Separated from'' means located in different cargo compartments or holds when stowed under deck. If the intervening deck is resistant to fire and liquid, a vertical separation, i.e., in different cargo compartments, is acceptable as equivalent to this segregation.
(2) ``Separated by a complete cargo compartment or hold from'' means either a vertical or horizontal separation, for example, by a complete cargo compartment or hold. If the intervening decks are not resistant to fire and liquid, only horizontal separation is acceptable.
(3) ``Separated longitudinally by an intervening complete cargo compartment or hold from'' means that vertical separation alone does not meet this requirement.
