Elements and Performance Criteria
Performance Evidence
An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.
There must be evidence that the individual has independently coordinated the safe and efficient set-up, operation, handover and shutdown of two complete shifts of wine filtration processes. Each shift must be a minimum of eight hours. The individual must coordinate the filtration of at least two different batches of juice or wine, according to work orders. For each shift, the individual must have:coordinatedat least two of the following:cross flowearth lenticular or padreverse osmosismembrane checked filtration performance parameters, including the specified integrity testing controlled product specifications, including:temperaturecarbon dioxidedissolved oxygennephelometric turbidity units (NTU)communicated with at least two cellar operations workers and with at least two of the following:wine makercellar operations managermaintenance team memberlaboratory team member.For each shift, the individual must have:coordinated at least two cellar operations workers, including scheduling start and finish times, meal and rest breaksaddressed quality issues and anomalies caused by equipment failure and operator erroraddressed team members’ health and safety requirements, including:correct fit and use of personal protective equipmentmachinery lock-out and isolationcompliance with vehicle and pedestrian traffic controlmonitored timely and accurate completion of workplace records, including:production notes, including additions to productsmachinery and equipment logsworkplace safety reportseffectively coordinated a batch changeover according to workplace time requirements.
