PSOC Sub-major group 81 — Stationary plant and machine operators (2026)
Stationary plant and machine operators monitor and operate stationary industrial plant, machinery and equipment, or for which mobility is not an integral part of operation. Competent performance in most occupations in this sub-major group requires skills at the second ISCO skill level. The work mainly calls for experience with and an understanding of the industrial plant, machinery or equipment being operated and monitored. Ability to cope with machine-paced operations and to adapt to innovations in machinery and equipment is often required. Tasks performed by workers in this sub-major group usually include: setting up, operating and monitoring a variety of stationary plant and machinery; detecting malfunctions and taking corrective action; examining outputs for defects and conformity to specifications and adjusting machine settings accordingly; performing maintenance, repairs and cleaning; recording data and maintaining production records. Supervision of other workers may be included. Occupations in this sub-major group are classified into the following minor groups: 811 Mining and Mineral Processing Plant Operators 812 Metal Processing and Finishing Plant Operators 813 Chemical and Photographic Products Plant and Machine Operators 814 Rubber, Plastic and Paper Products Machine Operators 815 Textile, Fur and Leather Products Machine Operators 816 Food and Related Products Machine Operators 817 Wood Processing and Papermaking Plant Operators 818 Other Stationary Plant and Machine Operators
