The hazard classification system described in this report employs four main classes of hazards: fire, health, water pollution, and reactivity; and further subdivides the health, water pollution, and reactivity into subclasses. Under each class or subclass, a numerical rating is given to indicate the relative degree of potential hazard. General guidelines were developed to describe five levels of severity for each. It should be borne in mind that these ratings relate to hazardous situations that may arise in the marine transportation of the materials under consideration, and are not necessarily applicable to other situations. The purpose of this system is to provide the parametric and procedural guidelines for making a comprehensive and consistent profile that reflects the inherent hazards of chemical and other cargoes transported in bulk by water. As used here, inherent refers to the hazards presented to life and property from the cargo itself when accidentally released, without consideration of the method or quality of its containment. Under normal ambient conditions the cargo may be a gas, a liquid, or a solid, but this system places greater emphasis on hazards of shipments in the liquid phase. Solids are considered only if shipped molten or in solution. Classification requires identifcation of the hazards and the comparative rating of each according to established guidelines. The intended use of the resulting hazard profile is to help the Coast Guard toward a more complete understanding of the requirements necessary to insure safe moving, handling, loading, and unloading procedures which collectively constitute the bulk water transportation system.
