Except as described in §150.160, the person in charge of a vessel shall ensure that the containment system for a cargo that is a hazardous material meets the following requirements: (a) The containment system must separate the hazardous material or its residue from any cargo in table I with which it is incompatible by two barriers such as formed by a: (1) Cofferdam; (2) Empty tank; (3) Void space; (4) Cargo handling space; (5) Tank containing a compatible cargo; or (6) Piping tunnel. (b) In this subpart, isolation across a cruciform joint is equivalent to isolation by two barriers.
