(a) The division may, upon good cause shown, and after notice to the employer or contractor by the division and an opportunity to be heard, revoke or suspend any registration issued to the employer or contractor to do asbestos-related work until certain specified written conditions are met.

(b) Any person who owns a commercial or industrial building or structure, any employer who engages in or contracts for asbestos-related work, any contractor, public agency, or any employee acting for any of the foregoing, who, contracts for, or who begins, asbestos-related work in any commercial or industrial building or structure built prior to 1978 without first determining if asbestos-containing material is present, and thereby fails to comply with the applicable laws and regulations, is subject to one of the following penalties:

(1) For a knowing or negligent violation, a fine of not more than five thousand dollars ($5,000) or imprisonment in the county jail for not more than six months, or both the fine and imprisonment.

(2) For a willful violation which results in death, serious injury or illness, or serious exposure, a fine of not more than ten thousand dollars ($10,000) or imprisonment in the county jail for not more than one year, or both the fine and imprisonment. A second or subsequent conviction under this paragraph may be punishable by a fine of not more than twenty thousand dollars ($20,000) or by imprisonment in the county jail for not more than one year, or by both the fine and imprisonment.

(c) It is a defense to an action for violation of this section if the owner, contractor, employer, public agency, or agent thereof, proves, by a preponderance of the evidence, that he or she made a reasonable effort to determine whether asbestos was present.
