A forward-looking guide to likely rulemaking, continuing obligations, and practical planning for California employers | Outlook prepared September 15, 2026

California employers should use the final months of 2026 to prepare for a potentially active 2027. Some requirements may become final before year-end; others remain proposals, petitions, or developing initiatives. This guide separates what employers must continue doing now from the issues most likely to shape next year. It is a planning resource, not legal advice, and should be refreshed after the Standards Board’s final 2026 meetings and again immediately before publication or implementation. 

At a Glance

• Workplace violence is the leading year-end issue. The Standards Board is directed to adopt a general-industry standard by December 31, 2026, while the existing statutory duties remain enforceable.
• Engineered-stone silica could produce further action. The Board granted a 2026 petition seeking expedited rulemaking on fabrication and installation of engineered stone containing more than one percent crystalline silica.
• Several 2026 proposals may become 2027 compliance projects. First aid, refinery process safety, construction hoist elevators, Elevator Safety Orders, and inspection walkaround representatives warrant continued monitoring.
• Federal GHS changes remain a planning issue, not a California implementation trigger. Employers should maintain current Title 8 compliance and wait for formal California action before revising programs solely for the federal update.

1. What Is—and Is Not—Known About 2027

 As of September 15, 2026, the official approved-regulations list does not identify a broad package of Cal/OSHA rules already scheduled to take effect in 2027. That does not mean 2027 will be quiet. Rules heard or developed during 2026 may be adopted, approved, and assigned a later effective date. Throughout this article, current requirement means enforceable now; pending means formal rulemaking is underway; and emerging means a petition, advisory process, or policy initiative may lead to future rulemaking. 

2. The Leading 2027 Issue: Workplace Violence Prevention

 Labor Code section 6401.9 has required covered general-industry employers to maintain an effective Workplace Violence Prevention Plan since July 1, 2024. The Standards Board is directed to adopt a general-industry workplace violence standard by December 31, 2026. If final action occurs on that timetable, implementation, interpretation, and enforcement of the Title 8 standard could become one of the most important Cal/OSHA developments of 2027. 

• Audit the existing plan against actual operations, not just the written template.
• Confirm employee participation, reporting channels, hazard identification and correction, training, violent-incident logging, post-incident review, and required record retention.
• Watch the final regulatory text for differences in scope, definitions, documentation, training, and corrective-action duties.
• Assign responsibility for comparing the final Title 8 standard with the organization’s current program and updating it by the applicable effective date.

3. The 2027 Regulatory Pipeline

Engineered Stone and Respirable Crystalline Silica

 California strengthened section 5204 in 2025 for high-exposure tasks involving artificial or engineered stone. In May 2026, the Standards Board granted Petition 609, which seeks expedited rulemaking to prohibit fabrication and installation tasks on engineered stone containing more than one percent crystalline silica. The petition decision starts a rulemaking path; it is not itself a ban. Employers should continue complying fully with the existing standard while monitoring any proposed or emergency text that could affect materials, fabrication methods, respiratory protection, medical surveillance, and supplier relationships in 2027. 

Hazard Communication and GHS Revision 7

 Federal OSHA completed its 2024 Hazard Communication rule and is phasing in changes aligned primarily with GHS Revision 7. California, however, operates its own OSHA-approved State Plan. California employers should continue to follow Title 8, section 5194 and monitor the Standards Board for state action. Do not redesign California labels, safety data sheet procedures, or training solely to implement the federal changes unless and until California formally adopts corresponding requirements with an effective date. Routine Hazard Communication compliance—and acceptance of updated supplier labels and SDSs—should continue. 

First Aid

 The Standards Board held a January 15, 2026 hearing on proposed revisions to Construction Safety Orders section 1512 and General Industry Safety Orders section 3400. The proposal addresses workplace first-aid supplies and related requirements. If adopted and approved, it could require employers to revisit kit contents, availability, inspection practices, and written procedures in 2027. Until then, the current standards remain controlling. 

Petroleum-Refinery Process Safety Management

 Proposed revisions to section 5189.1 were heard January 15, 2026. Covered refineries should follow the final record closely and prepare a structured crosswalk between the current program and any approved text. Potential implementation work may involve management systems, process-safety documentation, employee participation, contractor coordination, and audit practices. 

Construction Hoist Elevators and Elevator Safety Orders

 A proposal concerning elevators for hoisting workers under section 1630 was heard March 19, 2026, and broader revisions to the Elevator Safety Orders were heard June 18, 2026. Construction employers, building owners, and vertical-transportation contractors should monitor both proceedings for final scope, inspection, operation, maintenance, and implementation requirements. 

Inspection Walkaround Representatives

 A 2026 proposal concerning employer- and employee-authorized representatives during Cal/OSHA inspections could affect inspection protocols and who may accompany compliance personnel. Employers should prepare managers to preserve legal rights, cooperate appropriately, protect confidential information, and avoid retaliation—while waiting for final language before rewriting formal procedures. 

4. Continuing Cal/OSHA Priorities in 2027

 Even if no new rule applies to a particular workplace on January 1, employers should expect established standards to remain central to inspections and citations. Priority areas include the Injury and Illness Prevention Program; indoor and outdoor heat; workplace violence; lead; respirable crystalline silica; residential fall protection; properly fitting PPE; confined spaces in construction; covered diving operations; and required training, exposure, medical, inspection, and incident records. 

What Strong 2027 Programs Will Have in Common

• Written programs match actual equipment, tasks, locations, and staffing.
• Frontline supervisors can explain and enforce the required controls.
• Training is understandable, documented, and refreshed when conditions change.
• Employees can report hazards and incidents without fear of retaliation.
• Inspections, exposure assessments, corrective actions, and follow-up are documented.
• Host employers, contractors, and temporary staffing partners understand their respective responsibilities.

5. A Practical 2027 Readiness Plan

• Establish a year-end regulatory baseline. Identify which Title 8 standards apply by industry, location, task, and exposure, and confirm that current programs reflect amendments effective through 2026.
• Assign owners to each pending issue. Designate responsible leaders for workplace violence, silica, Hazard Communication, first aid, process safety, elevators, and inspection protocols as applicable.
• Use a trigger-based tracker. Record the proposal, current status, expected next event, responsible owner, affected operations, and the action that begins only after approval or an effective date.
• Budget before the rule is final. Identify potential equipment, training, medical-surveillance, consulting, staffing, and technology costs without prematurely changing the compliance program.
• Test programs in the field. Interview supervisors and employees, inspect work practices, sample records, and correct gaps between policy and execution.
• Refresh before publication and implementation. Recheck the Standards Board’s approved, proposed, emergency, and petition pages after the final 2026 meetings and throughout 2027.

Bottom Line

 Cal/OSHA’s 2027 story is still being written, but employers do not need to wait passively. The strongest approach is to maintain full compliance with existing standards, track formal rulemaking by status, prepare operational and budget scenarios, and implement changes only when the legal trigger is clear. Workplace violence and engineered-stone silica deserve the closest attention, while first aid, refinery process safety, elevator rules, inspection participation, and California’s eventual GHS response remain important watch items.
