Knowledge of: purpose and basic principles of each part of the process, such as volumetric metering, steam conditioning, pellet formation, cooling, crumbling and sieving and post-pelleting liquid addition 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 required and action to take if services are not available basic operating principles of process control, including the relationship between control panels and systems and the physical equipment the flow of the pelleting process and the effect of outputs on downstream processes quality characteristics and uses of finished pellets effect of variation in inputs and/or services on process performance operating requirements and parameters and corrective action required where operation is outside specified operating parameters the effect on final product of variation in variables, such as: pellet diameter to length ratios oil and fat content retention time and temperatures for steam conditioning, including consequences of temperatures that are too high and too low on chemical composition retention time and temperature for liquid addition 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 pelleting 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 common causes of variation and corrective action required contamination risks related to the pelleting and pellet finishing process and related controls occupational health and safety (OHS) hazards and controls, including the limitations of protective clothing and equipment relevant to the work process requirements of different shutdowns as appropriate to the process and workplace pelleting requirements, including emergency and routine shutdowns and procedures to follow in the event of a power outage product/process changeover procedures and responsibilities isolation, lock out and tag out 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 sampling and testing associated with process monitoring and control where relevant routine maintenance procedures where relevant cleaning and sanitation procedures where relevant |
