Workplace safety in California is closely tied to Cal-OSHA, the state agency responsible for developing and enforcing occupational safety and health requirements. California is one of the states authorized to operate its own OSHA “state plan,” which means it can create and enforce its own workplace safety regulations as long as those regulations are at least as effective as federal OSHA standards. Cal-OSHA operates under the California Department of Industrial Relations and plays a central role in how safety rules are interpreted, applied, and enforced across California workplaces.
Cal-OSHA’s core structure includes three main units: Consultation, Compliance, and the Legal or Criminal Unit, also known as the Bureau of Investigations. The Consultation Unit provides safety and health assistance to employers, often with a focus on small or high-hazard employers. This unit may provide outreach, educational materials, partnership programs, and on-site consultation visits. While consultation visits are not enforcement inspections, employers who accept assistance are generally expected to correct identified hazards in a timely manner.
The Compliance, or Enforcement, Unit is responsible for inspections, investigations, citations, and orders. Employers may encounter this unit because of complaints, serious injury or death reports, targeted inspection programs, referrals from law enforcement, or even observations made by a Cal-OSHA inspector. Once an inspection begins, it typically includes an opening conference, document requests, a physical inspection, and a closing conference. If citations are issued, the employer has limited time to act, which may include paying the fine, requesting an informal conference, or filing a formal appeal.
The Bureau of Investigations is the criminal investigation unit within Cal-OSHA and is generally involved when a workplace death or serious circumstance may raise questions of negligence or willful violations. The potential consequences can be significant, including referrals for criminal prosecution in certain situations. Separate from Cal-OSHA’s enforcement structure, the Occupational Safety and Health Appeals Board handles citation appeals, while the Occupational Safety and Health Standards Board adopts and updates safety regulations, including emergency regulations when necessary.
Understanding Cal-OSHA’s structure helps employers better prepare for interactions with the agency. A consultation visit, an enforcement inspection, a citation appeal, and a criminal investigation are very different situations, and each requires a different response. Employers should understand who they are dealing with, why the agency is involved, what rights and obligations apply, and how decisions made early in the process can affect the outcome.
California employers often have questions about inspections, citations, and appeals, making it important to understand how the agency is organized and how each division functions.
At Leavitt Pacific Insurance Brokers, we help employers better understand California safety requirements and prepare for Cal-OSHA-related issues before they become urgent. This Cal-OSHA structure resource can help leadership teams, supervisors, and safety personnel understand the agency’s major divisions, how inspections and citations may unfold, and why preparation is important when a Cal-OSHA representative arrives at the workplace.
