Lab. Code, § 6602

If an employer notifies the appeals board that they intend to contest a citation issued under Section 6317, or notice of proposed penalty issued under Section 6319, or order issued under Section 6308, or if, within 15 working days of the issuance of a citation or order an employee or representative of an employee files a notice with the division or appeals board alleging that the period of time fixed in the citation or order for the abatement of the violation is unreasonable, the appeals board shall afford an opportunity for a hearing. The appeals board shall thereafter issue a decision, based on findings of fact, affirming, modifying, or vacating the division’s citation, order, or proposed penalty, or directing other appropriate relief. If the division establishes an enterprise-wide violation, the appeals board shall include in its decision an enterprise-wide abatement order.
