AB 2321 California Assembly · 2025-2026 Regular Session

Occupational safety and health: investigations.

Summary
(1) Existing law establishes the Department of Industrial Relations, which includes the Division of Occupational Safety and Health. Existing law requires the division to investigate the causes of any employment accident that is fatal to one or more employees or that results in a serious injury, illness, or exposure, except as specified. Existing law requires the chief of the division and all qualified inspectors and investigators authorized by the chief to have free access to any place of employment to investigate and inspect and sets forth various other duties related to investigation and inspection, as specified. This bill would make it a misdemeanor to willfully resist, prevent, impede, or interfere with the chief or their authorized representative in the performance of the above-described duties or to willfully violate an order of the court relating to those duties. By creating a new crime, this bill would impose a state-mandated local program. Existing law makes it a public offense for any employer or any employee having direction, management, control, or custody of any employment, place of employment, or of any other employee who willfully violates any occupational safety or health standard, order, special order, if that violation caused death or permanent or prolonged impairment to the body of an employee, as specified. This bill would additionally make it a public offense if that violation caused serious injury, illness, or exposure. By expanding the scope of an existing crime, this bill would impose a state-mandated local program. (2) Existing law makes the Bureau of Investigations within the Division of Occupational Safety and Health responsible for directing accident investigations involving violations of laws, standards, and orders in which there is a serious injury to 5 or more employees, death, or request for prosecution by a division representative. Existing law requires the bureau to review inspection reports involving a serious violation if there have been serious injuries to one to 4 employees or a serious exposure, and authorizes the bureau to investigate cases for the purpose of prosecution, as specified. Existing law requires the bureau to refer the results of investigations it is required to conduct to the appropriate prosecuting authority having jurisdiction for appropriate action unless it determines that there is legally insufficient evidence of a violation of the law. This bill would revise and recast these requirements to, among other things, additionally require the bureau to investigate any accident in which there is a serious injury, illness, or exposure for which the division issues a citation for a willful violation. The bill would require the bureau to establish written policies and procedures for reviewing cases and deciding whether to investigate or refer them for prosecution. The bill would also require the division to establish a routine or automated process for transmitting information to the bureau about incidents with serious injuries, illnesses, or exposures so that the bureau can review them. Existing law authorizes the department, upon the request of a county district attorney, to develop a protocol for the referral of cases that may involve criminal conduct to the appropriate prosecuting authority in lieu of or in cooperation with an investigation by the bureau. This bill would require the division to immediately notify the appropriate prosecuting authority upon learning of an accident in which there is a serious injury, illness, or exposure to 5 or more employees, death, or request for prosecution by a division representative. The bill would delete the above-described provisions regarding developing a protocol and would instead authorize the bureau, upon request of an appropriate prosecuting authority, to refer cases that may involve criminal conduct to the appropriate prosecuting authority, as specified. The bill would require the bureau and the division, in cases accepted for investigation, to cooperate with the prosecuting authority. Existing law requires the bureau to submit an annual report to the division on its activities. This bill would additionally require the report to be submitted to the Legislature and to include information relating to certain cases involving a fatality that are referred by the bureau to the appropriate prosecuting authority, as specified. The bill would make the specifics of that information confidential. (3) Existing law requires all information reported to or otherwise obtained by the Chief of the Division of Occupational Safety and Health or representatives of the chief in connection with any inspection or proceeding of the division that contains or that might reveal a trade secret to be considered confidential, except that this information may be disclosed to other officers or employees of the division concerned with carrying out the purposes of the division or when relevant in any proceeding of the division, as specified. This bill would revise the above-described exception to also permit this information to be disclosed to law enforcement officers or prosecutors in any law enforcement investigation or prosecution. Existing law requires the responding agency, whenever a state, county, or local fire or police agency is called to an accident involving an employee covered by the California Occupational Safety and Health Act of 1973 in which a serious injury or illness, or death occurs, to immediately notify the nearest division office. Existing law then requires the division to immediately notify the appropriate prosecuting authority of the accident. This bill would expand this requirement to include an accident in which a serious exposure occurs. The bill would also require the responding agency to immediately notify the district attorney's office in the county where the accident occurred. The bill would additionally require the division to immediately notify the bureau, and the district attorney's office or other appropriate prosecuting authority, of the accident, whether the division received notification by the responding agency, the employer, or by other means. The bill would make other related and conforming changes to those provisions. (4) Existing constitutional provisions require that a statute that limits the right of access to the meetings of public bodies or the writings of public officials and agencies be adopted with findings demonstrating the interest protected by the limitation and the need for protecting that interest. This bill would make legislative findings to that effect. (5) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.

MAJOR
The August 27 amendment to AB 2321 makes two major structural changes: it removes the entire amendment to Labor Code Section 62.5 (which dealt with workers' compensation surcharges and fund allocations) and eliminates the Alameda/Santa Clara County pilot program that would have required those district attorneys to investigate fatal workplace incidents through 2032. The remaining provisions are streamlined, shifting terminology from 'incident' back to 'accident,' simplifying notification and referral processes, and removing a documentation requirement for bureau decisions.
SCOPE

The entire amendment to Labor Code Section 62.5 is removed. This section dealt with the Workers' Compensation Administration Revolving Fund, Uninsured Employers Benefits Trust Fund, Subsequent Injuries Benefits Trust Fund, Occupational Safety and Health Fund, Labor Enforcement and Compliance Fund, and employer surcharge provisions. The bill no longer touches funding or surcharge mechanisms.

The Alameda County and Santa Clara County pilot program is entirely removed. This provision would have required those district attorneys to investigate and prepare cases for prosecution of fatal workplace incidents in their counties, report to the Legislature by January 1, 2031, and operate under a sunset date of January 1, 2032. Related legislative findings and funding authorizations for those counties are also removed.

REQUIREMENT

Terminology is shifted from 'incident' back to 'accident' throughout the bill. The old version used 'incident' in multiple places (e.g., 'initial incident reports,' 'learning of an incident'), while the new version consistently uses 'accident.'

The immediate notification responsibility for serious workplace accidents shifts from the bureau to the division. The old text said 'the bureau shall immediately notify the appropriate prosecuting authority' while the new text says 'the division shall immediately notify the appropriate prosecuting authority.'

The case referral process is simplified. The old version allowed the department/bureau to refer cases 'in lieu of or in cooperation with an investigation by the bureau,' while the new version simply authorizes the bureau to refer cases upon request of a prosecuting authority, removing the 'in lieu of' language.

The bureau's review threshold for inspection reports is narrowed. The old version required the bureau to 'immediately review' reports involving serious injuries/illnesses/exposures to one to four employees OR a serious exposure. The new version requires the bureau to 'review' (without 'immediately') reports involving serious injuries/illnesses/exposures to one to four employees, removing the standalone 'or a serious exposure' trigger.

A documentation requirement is removed from the bureau's written policies and procedures. The old version required the bureau to document its rationale for why it decided not to investigate or not to refer each case. The new version simply requires written policies for reviewing cases and deciding whether to investigate or refer them.

The information transmission process from the division to the bureau is changed. The old version required transmitting information about 'cases with nonfatal injuries' while the new version requires transmitting information about 'incidents with serious injuries, illnesses, or exposures.' This narrows the scope from all nonfatal injuries to only serious ones.

The bureau's annual report to the Legislature is changed. The old version required information about job classifications and vacancies within the bureau as well as fatality cases referred for prosecution. The new version focuses only on 'certain cases involving a fatality that are referred by the bureau to the appropriate prosecuting authority,' removing the staffing/vacancy reporting requirement.

TECHNICAL

The word 'immediately' is removed from several timing requirements, replaced with just 'promptly.' For example, the bureau's investigation duty changes from 'immediately promptly investigate' to 'promptly investigate,' and referral of results changes from 'immediately promptly referred' to 'promptly referred.'
