Class code 3179 — Machine Shop — Manufacturing NOC
General machine-based manufacturing not otherwise classified.
This classification serves as a catch-all for machine-based manufacturing operations that don't fit a more specific product or process description. It typically applies to shops producing custom or small-batch metal or mechanical components using general-purpose machinery.
Because this is a not-otherwise-classified code, the exact mix of equipment and payroll varies by business, but commonly includes machine operators, assemblers, and general shop labor working with powered tools to manufacture parts or products for sale to other businesses.
Injury exposure mirrors general machine shop hazards: point-of-operation contact with cutting or moving machine parts, manual material handling strain, and exposure to metal chips or scrap. Because the classification covers varied operations, underwriters look closely at the specific equipment and processes in use to confirm the code fits.
What code 3179 typically includes
- General machine operators on varied equipment
- Assembly staff for manufactured components
- Material handlers moving stock and finished goods
- Shop maintenance and setup personnel
- Quality control staff checking finished parts
