Waterways - HMT Columns 1 - 10

The ten major headings of the HMT can be divided into two groups. The first five major headings provide information for the HAZMAT basic description that is required on shipping papers. Then last five major headings provide specialized information necessary for packaging, marking, and labeling and specific requirements for the mode of transportation used.

• Column 1, Symbols
• Column 2, Hazardous Materials Descriptions and Proper Shipping Names
• Column 3, Hazard Class or Division
• Column 4, Identification Numbers
• Column 5, PG
• Column 6, Label Codes
• Column 7, Special Provisions
• Column 8, Packaging
• Column 9, Quantity Limitations, 9A and 9B
• Column 10, Vessel Stowage, 10A and 10B

Particular to waterway transport is Column 10. Column 10A specifies the authorized stowage locations for hazardous materials on board cargo and passenger vessels. Column 10B specifies codes for stowage requirements for specific hazardous materials. These codes are defined in §176.84; we will discuss them in more detail later in the course.
