Class Code 2121
Breweries
Class code 2121 applies to breweries — the businesses that produce, ferment, package and often ship beer. The California WCIRB approved pure premium rate for this class is $2.860 per $100 of payroll, which reflects the industrys specific loss experience and hazards.
What Class Code 2121 Covers
This classification covers on-site brewing operations including mash tuns, kettles, fermentation and conditioning tanks, cellar operations, cleaning-in-place (CIP) activities, packaging lines (bottling, canning, kegging), bulk transfer and palletizing, and warehouse/shipping tied to production. It includes small craft breweries, regional production breweries, contract brewers and brewpub production areas when those operations are part of the brewerys manufacturing process. Work that is purely retail (stand-alone bars or restaurants without production) is generally not included under 2121 and is coded separately. The code also applies to ancillary lab and quality control work tied directly to production, and to operators of forklifts and pallet jacks in the brewerys production and distribution areas.
Who It Applies To
- Head brewers, assistant brewers and cellar workers
- Packaging line operators (bottling, canning, kegging)
- Sanitation and CIP technicians who clean tanks and lines
- Quality control and laboratory technicians working on-site
- Warehouse staff and forklift operators handling finished goods
- Maintenance mechanics servicing brewing and packaging equipment
Common Job Duties
- Operating mash tuns, kettles and heat exchange systems
- Transferring wort and beer between vessels and filtration systems
- Cleaning and sanitizing fermentation tanks and pipelines using caustic and acidic chemicals (CIP)
- Running and maintaining automated bottling, canning or kegging lines
- Filling, pressurizing and inspecting kegs and packaged product
- Loading/unloading pallets, operating forklifts and preparing shipments
- Collecting samples, running microbiological and chemical QC tests
Common Injury Risks
Understanding the $2.860 Rate
The approved pure premium rate of $2.860 per $100 of payroll represents the expected cost of losses for employers in class 2121 before insurer expenses and profit. To estimate the pure premium, divide payroll by $100 and multiply by 2.860; insurers then add loading for overhead, state assessments, policy fees and any modifications (experience modification, schedule credits/debits) to produce the final premium. Final cost is affected by your payroll mix (production vs. clerical), your claims history (XMod), workplace safety programs, job classification accuracy and any deductible or retrospective rating plans.
Cal/OSHA Compliance Requirements
California employers operating breweries must maintain a written Injury and Illness Prevention Program (IIPP) and comply with Cal/OSHA standards for hazard communication, respiratory protection, machine guarding and lockout/tagout where applicable. Permit-required confined space procedures, atmospheric testing and rescue planning are often required for fermentation and tank entry. Employers should also implement CO2 monitoring and ventilation controls, provide PPE for chemical handling and hot processes, and offer training specific to CIP chemicals, forklift operation and hearing conservation.
How Key HR Helps Employers Under Class Code 2121
A PEO like Key HR can help breweries control workers compensation costs by ensuring correct classification of payroll, implementing tailored loss-prevention programs (confined-space procedures, CO2 monitoring, CIP chemical controls), and managing claims and return-to-work plans to reduce severity. Key HR also provides safety training, recordkeeping to meet Cal/OSHA, and access to broader insurance pools and loss-control specialists that can lower underwriting adjustments and improve experience modification factors.

Do taproom servers and bartenders count under code 2121?
Taproom staff employed by a production brewery at the same location are often covered under the brewerys overall classification for payroll directly tied to production or taproom operations; however, pure retail bar operations and restaurant servers are typically coded under different retail or bar classifications. Accurate payroll allocation between production and retail activities is essential to ensure correct pricing.
What practical steps lower workers comp costs for breweries?
Key steps include developing and enforcing written confined space and permit-entry procedures, CO2 monitoring and ventilation, thorough CIP chemical handling and HAZCOM training, machine guarding and lockout/tagout programs, a structured return-to-work plan, and proactive claims management to limit lost-time severity.
When is confined space training required in a brewery?
Confined space training and a permit system are required whenever employees enter fermentation tanks, silos or other enclosed vessels where hazardous atmospheres (low oxygen, high CO2) or engulfment risks may exist. Employers must test atmospheres, provide appropriate PPE and rescue plans, and train entrants and attendants per Cal/OSHA requirements.
