Knowledge of: purpose and basic principles of the washing process, including the importance of water quality and the role of chemicals in the washing process basic operating principles of equipment, such as main equipment components, status and purpose of guards, equipment operating capacities and applications, and the purpose and location of sensors and related feedback instrumentation services (principally water) required and action to take if services are not available the flow of this process and the effect of outputs on downstream processes quality characteristics to be achieved by the washing, including the consequences of out-of-specification moisture levels on further processing and final product quality requirements of raw materials and effect of variation on process performance, including how variation in microbial load can affect the washing process operating requirements, parameters and corrective action required where operation is outside specified operating parameters typical equipment faults and related causes, including signs and symptoms of faulty equipment and early warning signs of potential problems methods used to monitor the washing process, such as inspecting, measuring and testing as required by the process inspection or test points (control points) in the process and the related procedures and recording requirements contamination/food safety risks associated with the process and related control measures common causes of variation and corrective action required occupational health and safety (OHS) hazards and controls requirements of different shutdowns as appropriate to the process and workplace production requirements, including emergency and routine shutdowns and procedures to follow in the event of a power outage isolation, lock out and tag out procedures and responsibilities product/process changeover procedures and responsibilities procedures and responsibility for reporting production and performance information environmental issues and controls relevant to the process, including waste/rework collection and handling procedures related to the process basic operating principles of process control, where relevant, including the relationship between control panels and systems and the physical equipment sampling and testing associated with process monitoring and controlwhere relevant routine maintenance procedureswhere relevant cleaning and sanitation procedures where relevant |
