Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.ContextThis competency applies to all powder coating processes within the plastics and rubber industries. It includes the operation of all relevant additional equipment where that equipment is integral to the powder coating process.ProceduresAll operations are performed in accordance with procedures.Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards. Tools and equipmentThis competency includes use of equipment and tools such as:powder coating spray equipment and ancillariesracks, baskets and supports, including overhead tracks and drives curing ovens and controlshand tools used in the powder coating process powder handling equipmentrelevant personal protective equipment.HazardsTypical hazards include:hazardous chemicals, pre-treatment chemicals and powder coating materialhumidity, air temperatures, radiant heat, hot surfaces stationary and moving machinery, parts and components temperaturemanual handling hazards equipment operations.Problems'Anticipate and solve problems' means resolve a wide range of routine and non-routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/a solution recorded in the procedures.Typical process and product problems may include:poor pre-treatment coverage, drainage or compatibility colour variationblemishes uneven coatingover/under cured coatingvariations in materials and/or contamination of materials processing problems.Fault causesFault causes include:substrate surface conditionpre-treatment effectivenessspray applicationpowderoven conditionsincorrect quantity of materialscontaminated materials.VariablesKey variables to be monitored include:spray application and coverage operating temperaturesspeed colour cycle timecoating integrity and general conformance to specification/sample.
