Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
This describes the essential skills and knowledge and their level required for this unit.
Application of knowledge of the materials, equipment and process sufficient to recognise out of specification products, process problems and materials faults.
Knowledge of organization procedures, quality requirements and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.
Application of the knowledge of managing risk using the hierarchy of controls applied to the coating process. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup
Knowledge and skills in the operation of the surface coating process and equipment sufficient for consistent production of quality products, including:
production workflow sequences and materials demand
correct selection and use of equipment or tool/s, materials, processes and procedures
accurately monitoringequipment operation and product quality
reasons for checking process control panels and reporting readings which are outside of the normal range of process variability
identifying factors which may affect product quality or production output and appropriate remedies
potential effectsof variations in materials and equipment operation in relation to quality of product
processing behaviour of polymers and the role of additives
effect of unauthorised or emergency work stoppage in relation to safety and production requirements
waste management and knowing the importance of reusing non-conforming products wherever possible
basic pre-blending of materials
application of coatings.
Competence also includes the ability to:
plan own work, including predicting consequences and identifying improvements
identify when the operator is able to rectify faults, when assistance is required and who is the appropriate source for assistance
identify and describe own role and role of others involved directly in the coating process.
Language, literacy and numeracy requirements
This unit requires the ability to read and interpret typical product specifications, job sheets, procedures, material labels and safety information as provided to operators.
Writing is required to the level of completing workplace forms.
Basic numeracy is required, eg to determine that two 25 kg bags are needed to make up a requirement for 50 kg.
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.
Context
This competency applies to all surface coating operations using liquid coatings. It includes the operation of all relevant additional equipment where that equipment is integral to the coating process.
Procedures
All 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 equipment
This competency includes use of equipment and tools such as:
coating equipment (such as brushes, spray guns film coaters, immersion equipment)
additional equipment (such as vapour extraction, application booths)
manual handling aids (such as hand carts, trolleys)
hoists/lifting equipment not requiring any special permits or licences
relevant personal protective equipment.
Hazards
Typical hazards include:
spills and splashes
toxic fumes or vapours
hazardous materials
manual handling hazards
flammable vapours.
Problems
'Respond to routine problems' means apply known solutions to a limited range of predictable problems. Typical process and product problems may include:
incorrect selection of materials
variations in materials
contamination of materials or product surface
inappropriate application of coatings
dust and other contamination
drying rates
film thickness variation
film application rates
coverage and opacity
products with surface or other faults.
Appropriate action for non-routine problems may be reporting to designated person or other action specified in the procedures.
Variables
Key variables to be monitored include:
spray patterns
materials consistency
finished colour
surface finish
product integrity and general conformance to specifications
coating viscosity
solvent/thinner blend ratios.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
