- (a) This section applies only to cargoes identified in Table 148.10 of this part with a reference to this section and cargoes identified in the IMSBC Code (incorporated by reference, see § 148.8) as cargoes that may liquefy.
(b) This section does not apply to—
- (1) Shipments by unmanned barge; or
- (2) Cargoes of coal that have an average particle size of 10mm (.394 in.) or greater.
(c) Definitions as used in this section—
- (1) Cargo subject to liquefaction means a material that is subject to moisture migration and subsequent liquefaction if shipped with moisture content in excess of the transportable moisture limit.
- (2) Moisture migration is the movement of moisture by settling and consolidation of a material, which may result in the development of a flow state in the material.
- (3) Transportable moisture limit or TML of a cargo that may liquefy is the maximum moisture content that is considered safe for carriage on vessels.
- (d) Except on a vessel that is specially constructed or specially fitted for the purpose of carrying such cargoes (see also section 7 of the IMSBC Code, incorporated by reference, see § 148.8), a cargo subject to liquefaction may not be transported by vessel if its moisture content exceeds its TML.
- (e) The shipper of a cargo subject to liquefaction must give the master the material's moisture content and TML.
(f) The master of a vessel shipping a cargo subject to liquefaction must ensure that—
- (1) A cargo containing a liquid is not stowed in the same cargo space with a cargo subject to liquefaction; and
- (2) Precautions are taken to prevent the entry of liquids into a cargo space containing a cargo subject to liquefaction.
- (g) The moisture content and TML of a material may be determined by the tests described in Appendix 2, Section 1, of the IMSBC Code (incorporated by reference, see § 148.8).
