Class code 8601 applies to consulting engineers, oil and gas geologists/scouts, and forest engineers working in California. The WCIRB-approved pure premium rate for Sept 1, 2026 is $0.365 per $100 of payroll. Knowing this classification helps California employers assign payroll correctly and manage safety and claims exposure.
This classification covers professional engineering and geological staff who perform consulting, field surveys, site inspections, resource assessments and related technical services. Included are office-based engineers who regularly perform field visits and geologists or scouts who conduct seismic, stratigraphic, hydrologic or surface geology studies for oil and gas exploration. Forest engineers who design road systems, assess stand conditions, and supervise timber cruising and harvest layout are also in this code. Purely clerical staff or engineering technicians who spend almost all time in an office may require a different classification; the determining factor is the nature and location of the work, especially time spent in the field.
The pure premium rate of $0.365 per $100 payroll is the WCIRB's base loss cost representing expected claim costs for this classification. To estimate an employer's premium, divide total payroll by 100 and multiply by $0.365; insurers then apply policy-level loadings, experience modification (XMod), credits or debits, and any payroll discounts or retrospective adjustments. Final cost is affected by accurate class assignment, claims history, safety programs, and payroll reporting.
Fieldwork for this class is subject to Cal/OSHA requirements such as the Injury and Illness Prevention Program (IIPP), Heat Illness Prevention for outdoor workers, Hazard Communication for any chemicals encountered, and Respiratory Protection if dust or contaminants are present. Work on contaminated sites may trigger HAZWOPER training and controls, and forest operations must follow Cal/OSHA logging and tree-felling safety orders and PPE requirements. Employers must also maintain vehicle safety policies and training for staff who drive to remote sites.
A PEO like Key HR can help employers in this classification by ensuring accurate class code assignment and payroll reporting, implementing targeted safety programs (heat illness plans, field hazard checklists, driving policies), and managing claims and return-to-work strategies to protect experience modification. Key HR’s centralized claims handling, training delivery, and OSHA recordkeeping support can reduce reportable incidents and the administrative burden on small consulting firms.
Get a QuoteClassification hinges on the nature and frequency of fieldwork. If engineers spend significant time conducting surveys, sampling, or site inspections, 8601 is appropriate; purely office-based professionals with rare site visits may fall under a different professional or clerical code. Have payroll and duty descriptions ready for a class code audit.
Yes: under WCIRB code 8601 the pure premium rate covers the listed occupations (consulting engineers, oil/gas geologists/scouts, forest engineers). Your actual premium can still vary due to your company’s payroll size, experience modification, claims record, and insurer loadings.
Adopt a written IIPP, heat illness prevention and wildlife awareness training, enforce vehicle safety and seatbelt use, provide appropriate PPE, document pre‑work site hazard assessments, and establish light-duty return-to-work plans. Coupled with proactive claims management and accurate payroll classification, these steps lower injuries and the experience modification.
