Handling, Loading, Stowage and Segregation

Each mode of transportation has different requirements for these topics, as the risks involved in each is slightly different. For example, a marine pollutant traveling by rail does not have the same potential risks as when it is being transported by vessel.

Segregation is defined as "the process of separating two or more substances or articles which are considered mutually incompatible when their packing or stowage together may result in undue hazards in case of leakage, spillage, or any other incident." Spaces between two incompatible dangerous goods can be filled with other cargo compatible with the dangerous substances.

These terms are specifically defined based on the mode in which they are being transported. There are many possible combinations of dangerous substances, materials, and articles that require segregation.

Stowage is defined as "the proper placement of dangerous goods in order to ensure safety and environmental protection during transport."

Terms likely to be encountered when discussing segregation and stowage include the following:

• "away from"
• "separated from"
• "separated by a complete compartment or hold from"
• "separated longitudinally by an intervening complete compartment or hold from"
