Class Code 2710
Sawmills Or Shingle Mills; Log Chipping; Wood Treating/Preserving
Class Code 2710 covers sawmills, shingle mills, log chipping and wood treating/preserving operations in California. The WCIRB pure premium rate for 2710 is $6.952 per $100 of payroll, a rate that reflects the heavy machinery, material handling and chemical exposures common to these operations. Understanding this classification helps employers control costs and meet Cal/OSHA obligations.
What Class Code 2710 Covers
This classification applies to industrial mill operations where logs are received and processed into lumber or shingles, where logs are chipped or ground, and where wood products undergo preservation treatments. Typical operations include debarking, primary sawing, resawing, edging, planing, drying/kiln operations, and mechanical log chipping, plus the chemical processes used in pressure-treating, dipping or creosoting. It covers mill production staff, material handlers, equipment operators and maintenance crews who work inside the plant and on the yard; it does not cover logging in the forest (those activities are in separate logging class codes). Also included are activities tied directly to preserving operations such as loading/unloading treatment tanks, monitoring chemical feed systems, and managing treatment wastewater or containment.
Who It Applies To
- Sawmill owners and production line sawyers
- Shingle mill operators and packagers
- Log chipping contractors and chipper operators
- Wood treating/preserving plant operators and chemical handlers
- Mill maintenance technicians and millwrights
- Forklift operators, yard loaders and truck loaders at the mill
Common Job Duties
- Feeding logs into circular, band or head saws and operating resaws and edgers
- Operating log chippers, grinders and conveyance systems
- Loading, unloading and stacking lumber and treated timber using forklifts or loaders
- Operating and monitoring pressure treatment systems, dip tanks and chemical dosing equipment
- Routine maintenance, machine setup, blade changes and lockout/tagout activities
- Kiln operation and moisture testing, plus inspection and grading of finished lumber
- Handling, labeling and storing preservative chemicals and maintaining containment systems
Common Injury Risks
Understanding the $6.952 Rate
The approved pure premium rate of $6.952 per $100 of payroll is the WCIRB’s base cost to fund expected losses for Class Code 2710 before insurer adjustments. Insurers apply this rate to your class-specific payroll to calculate base premium, then adjust it for your company's experience modification, policy fees, state assessments and any credits for return-to-work or safety programs. Final premiums can change with payroll audits, claims history, correct employee classification and loss-control measures.
Cal/OSHA Compliance Requirements
Cal/OSHA enforces standards that are highly relevant to sawmills and treating plants including machine guarding and woodworking safety, respiratory protection, hearing conservation, Hazard Communication (SDS/GHS) and lockout/tagout. Facilities with treatment tanks and confined chemical storage must also comply with permit-required confined space procedures, spill prevention and hazardous waste handling; employers should perform exposure monitoring for wood dust and preservative chemicals and document training and medical surveillance as required.
How Key HR Helps Employers Under Class Code 2710
A PEO like Key HR helps employers in Class Code 2710 by ensuring correct classification and payroll allocation, implementing mill-specific safety programs (machine guarding, LOTO, respirator and hearing programs), and managing claims and return-to-work plans to limit experience modification increases. Key HR provides centralized claims advocacy, loss-control consulting and OSHA recordkeeping support—services that reduce disruption on the mill floor and help contain workers' comp costs across California operations.

How do I know whether a worker belongs in Class Code 2710 or another code?
Use where the employee’s primary duties are performed: 2710 covers on-site mill processing, chipping and wood treatment/preserving. Drivers, logging crews working in the forest, tree service crews or off-site contractors may fall under different codes. Document job descriptions and payroll allocation and confirm with your insurer or PEO during audit to avoid misclassification.
What practical steps reduce workers' comp costs for a mill or treating plant?
Focus on machine guarding, strict lockout/tagout, effective dust control and ventilation, a respiratory protection program, hearing conservation, chemical handling training and spill containment. Implement a formal return-to-work program, timely claim reporting, routine safety audits and preventive maintenance to cut claim frequency and severity.
What will a Cal/OSHA inspector look for during a mill visit?
Inspectors typically check machine guarding and point-of-operation protection, LOTO procedures, respiratory protection and air monitoring for dust and chemicals, Hazard Communication documentation and SDS availability, confined space and tank entry controls for treating operations, and housekeeping to reduce combustible dust hazards. Being able to show training records and exposure monitoring results reduces inspection risk.
