A l is best. Column 7 specifies codes for special provisions applicable to hazardous materials. When Column 7 refers to a special provision for a hazardous material the meaning and requirements of that special provision are as set forth in 172102 of this subpart.
A The Hazardous Materials Table Table in this section designates the materials listed therein as hazardous materials for the purpose of transportation of those materials. For each listed material the Table identifies the hazard class or specifies that the material is forbidden in transportation and gives the proper shipping name or directs the user to the preferred proper shipping name.
