California Code, Business and Professions Code - BPC § 7058.5

(a) A contractor shall not engage in asbestos-related work, as defined in Section 6501.8 of the Labor Code, that involves 100 square feet or more of surface area of asbestos containing materials, unless the contractor holds a C-22 Asbestos Abatement classification or the qualifier for the license passes an asbestos certification examination. Additional updated asbestos certification examinations may be required based on new health and safety information. The decision on whether to require an updated certification examination shall be made by the Contractors State License Board, in consultation with the Division of Occupational Safety and Health in the Department of Industrial Relations and the Division of Environmental and Occupational Disease Control in the State Department of Public Health.

No asbestos certification examination shall be required for contractors involved with the installation, maintenance, and repair of asbestos cement pipe or sheets, vinyl asbestos floor materials, or asbestos bituminous or resinous materials.

“Asbestos,” as used in this section, has the same meaning as defined in Section 6501.7 of the Labor Code.

(b) The Contractors State License Board shall make available to all applicants, either on the board's internet website or, if requested, in hard copy, a booklet containing information relative to handling and disposal of asbestos, together with an open book examination concerning asbestos-related work. All applicants for an initial contractor license shall complete the open book examination and, prior to the issuance of a contractor's license, submit it to the board electronically or by mail if the applicant elects to use the hard-copy format.
