California Asbestos Certification (ASB)

No contractor shall engage in asbestos-related work, as defined in Section 6501.8 of the Labor Code, which involves 100 square feet or more of surface area of asbestos containing materials, unless 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 State Department of Health Services.

Contractors with an asbestos certification can only perform abatement work within the license classification(s) they already hold.
