Special Provision 3 indicates that the material is poisonous by\ninhalation in Hazard Zone C. Special Provision 3 also references §173.116(a) - Class 2,\nAssignment of Hazard Zone. Section 173.116(a) states that the hazard zone for a\nDivision 2.3 material is assigned in Column 7 of the §172.101 table. The criteria\nspecified in §173.116(a) for assignment of hazard zones are to be used when the\n§172.101 table provides more than one hazard zone for a Division 2.3 material, or\nindicates that the hazard zone must be determined on the basis of the grouping criteria for\nof the HMT; thus, Hazard Zone C is the correct hazard zone designation for this material.\nDivision 2.3.
