Sections 452 and 669 of the Evidence Code shall apply to this division and to occupational safety and health standards adopted under this division in the same manner as any other statute, ordinance, or regulation. The testimony of employees of the division shall not be admissible as expert opinion or with respect to the application of occupational safety and health standards. It is the intent of the Legislature that the amendments to this section enacted in the 1999–2000 Regular Session shall not abrogate the holding in Brock v.
