142.3.  (a) (1) The board, by an affirmative vote of at least four members, may adopt, amend or repeal occupational safety and health standards and orders. The board shall be the only agency in the state authorized to adopt occupational safety and health standards.(2) The board shall adopt standards at least as effective as the federal standards for all issues for which federal standards have been promulgated under Section 6 of the Occupational Safety and Health Act of 1970 (P.L. 91-596) within six months of the promulgation date of the federal standards and which, when applicable to products which are distributed or used in interstate commerce, are required by compelling local conditions and do not unduly burden interstate commerce.(3) No standard or amendment to any standard adopted by the board that is substantially the same as a federal standard shall be subject to Article 5 (commencing with Section 11346) and Article 6 (commencing with Section 11349) of Chapter 3.5 of Part 1 of Division 3 of Title 2 of the Government Code. For purposes of this subdivision, “substantially the same” means identical to the federal standard with the exception of editorial and format differences needed to conform to other state laws and standards.(4) If a federal standard is promulgated and no state standard that is at least as effective as the federal standard is adopted by the board within six months of the date of promulgation of the federal standard, the following provisions shall apply unless adoption of the state standard is imminent:(A) If there is no existing state standard covering the same issues, the federal standard shall be deemed to be a standard adopted by the board and enforceable by the division pursuant to Section 6317. This standard shall not be subject to Article 5 (commencing with Section 11346) and Article 6 (commencing with Section 11349) of Chapter 3.5 of Part 1 of Division 3 of Title 2 of the Government Code.(B) If a state standard is in effect at the time a federal standard is promulgated covering the same issue or issues, the board may adopt the federal standard, or a portion thereof, as a standard enforceable by the division pursuant to Section 6317; provided, however, if a federal standard or portion thereof is adopted which replaces an existing state standard or portion thereof, the federal standard shall be as effective as the state standard or portion thereof. No adoption of or amendment to any federal standard, or portion thereof shall be subject to Article 5 (commencing with Section 11346) and Article 6 (commencing with Section 11349) of Chapter 3.5 of Part 1 of Division 3 of Title 2 of the Government Code.(C) Any state standard adopted pursuant to subparagraph (A) or (B) shall become effective at the time the standard is filed with the Secretary of State, unless otherwise provided, but shall not take effect before the effective date of the equivalent federal standard and shall remain in effect for six months unless readopted by the board for an additional six months or superseded by a standard adopted by the board pursuant to paragraph (2) of subdivision (a).(D) Any standard adopted pursuant to subparagraph (A), (B), or (C), shall be published in Title 8 of the California Code of Regulations in a manner similar to any other standards adopted pursuant to paragraphs (1) and (2) of subdivision (a) of this section.(b) The State Building Standards Commission shall codify and publish in a semiannual supplement to the California Building Standards Code, or in a more frequent supplement if required by federal law, all occupational safety and health standards that would otherwise meet the definition of a building standard described in Section 18909 of the Health and Safety Code adopted by the board in the State Building Standards Code without reimbursement from the board. These occupational safety and health standards may also be published by the Occupational Safety and Health Standards Board in other provisions in Title 8 of the California Code of Regulations prior to publication in the California Building Standards Code if that other publication includes an appropriate identification of occupational safety and health standards contained in the other publication.(c) Any occupational safety or health standard or order promulgated under this section shall prescribe the use of labels or other appropriate forms of warning as are necessary to ensure that employees are apprised of all hazards to which they are exposed, relevant symptoms and appropriate emergency treatment, and proper conditions and precautions for safe use or exposure. Where appropriate, these standards or orders shall also prescribe suitable protective equipment and control or technological procedures to be used in connection with these hazards and shall provide for monitoring or measuring employee exposure at such locations and intervals and in a manner as may be necessary for the protection of employees. In addition, where appropriate, the occupational safety or health standard or order shall prescribe the type and frequency of medical examinations or other tests which shall be made available, by the employer or at his or her cost, to employees exposed to such hazards in order to most effectively determine whether the health of such employee is adversely affected by this exposure.(d) The results of these examinations or tests shall be furnished only to the Division of Occupational Safety and Health, the State Department of Health Services, any other authorized state agency, the employer, the employee, and, at the request of the employee, to his or her physician.(Amended by Stats. 2002, Ch. 1124, Sec. 41. Effective September 30, 2002.)
