Section 339 - The Hazardous Substances List

(a) Purpose. The following is the List of Hazardous Substances prepared by the Director pursuant to Labor Code Section 6380. The substances on this list are subject to the provisions of Labor Code Sections 6360 through 6399.7 and Section 5194 in Title 8 of the California Code of Regulations.

(b) Definitions.

(1) CAS number means the unique identification number assigned by the Chemical Abstracts Service to specific chemical substances.

(2) Source means the sublists which the Director used in preparing the Hazardous Substances List pursuant to Labor Code 6382. The source(s) of each hazardous substance on the list is designated by a number in the middle column of the list. The numbers represent the following sources:

(1) International Agency for Research on Cancer (IARC);

(2) Environmental Protection Agency lists pursuant to the Clean Air and Clean Water Acts;

(3) General Industry Safety Order Section 5155;

(4) California Department of Pesticide Regulation's list of Restricted Materials;

(5) Information Alerts put out by the Hazard Evaluation and Information Service pursuant to Labor Code Section 147.2.

(3) Synonym means an entry in the list which refers to another entry. This type of entry may identify alternate names for a given substance or associate a particular substance with a class of substances. Synonyms appear in the list as entries of the form: Substance x; see Substance y. The synonym entries included in this list are not all inclusive.

HAZARDOUS SUBSTANCES LIST^*

^* An MSDS is not required for tapes, films, or extruded, molded or coated products containing listed hazardous substances in bound form except when these substances can be released in the workplace under normal conditions of work or in reasonably foreseeable emergencies resulting from workplace operations.
