§150.130. Loading a cargo on vessels carrying cargoes with which it is incompatible.
46 C.F.R. § 150.130
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:
The containment system must separate the hazardous material or its residue from any cargo in table 1 with which it is incompatible by two barriers such as formed by a:
Cofferdam;
Empty tank;
Void space;
Cargo handling space;
Tank containing a compatible cargo; or
Piping tunnel.
In this subpart, isolation across a cruciform joint is equivalent to isolation by two barriers.
The containment system for the hazardous material must not have a piping or venting system that connects to a containment system carrying a cargo with which the hazardous material is incompatible. Any such piping or venting system must have been separated from the containment system carrying the incompatible cargo by:
Removing a valve or spool piece and blanking off the exposed pipe ends, or
Installing two spectacle flanges in series with a means of detecting leakage into the pipe between the spectacle flanges.
