- HMT Column 6 identifies the label codes for the hazard warning labels required for the material.
Column 6 of the Hazardous Materials Table (HMT) identifies the label codes that represent the hazard warning label(s) that must be applied to the material’s packaging — unless the material is excepted from the labeling requirements. When more than one label code is listed, the first code shown indicates the material’s primary hazard. Additional label codes indicate subsidiary hazards.
If a material has more than one hazard, all applicable subsidiary labels may not be listed in Column 6. In such cases, users should consult 172.402.
