Notes

In some jobs, the work of process control technicians may be combined with supervision of staff in other occupations, such as plant and machine operators and assemblers. These jobs should be classified in Minor Group 313: Process Control Technicians, unless supervision of other workers is the clearly predominant element of the work and the process control activities are relatively simple. For example, a chemical processing plant controller who operates and monitors chemical processing units and equipment from a central control room, and also supervises the activities of chemical products plant and machine operators, should be classified in Unit Group 3133: Chemical Processing Plant Controllers. A supervisor of assemblers, however, who is also responsible for start up and shut down of a partially automated assembly line is classified in Unit Group 3122: Manufacturing Supervisors. Operators of single process plant and machines, or of machinery that does not involve automated control of multiple processes, are not included in Minor Group 313: Process Control Technicians. Such occupations are mainly classified in Major Group 8: Plant and Machine Operators and Assemblers. All mining plant operators are classified in Unit Group 8111, Miners and Quarriers.
