Sec. 116.4  Designation of hazardous substances.

    The elements and compounds appearing in Tables 116.4 A and B are 
designated as hazardous substances in accordance with section 
311(b)(2)(A) of the Act. This designation includes any isomers and 
hydrates, as well as any solutions and mixtures containing these 
substances. Synonyms and Chemical Abstract System (CAS) numbers have 
been added for convenience of the user only. In case of any disparity 
the common names shall be considered the designated substance.
