Application
This unit of competency covers setting up, operating and maintaining mechanical coating systems in order to apply coatings to specifications.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. | ||

3.5 | Products are inspected and approved for suitability for further processing | ||
3.6 | Defects are dealt with and/or reported in accordance with workplace procedures | ||
4 | Clean work area and maintain equipment | 4.1 | Equipment is cleaned and inspected for serviceable condition and stored appropriately |
4.2 | Unserviceable equipment is tagged, faults are identified and appropriate personnel are informed | ||
4.3 | Work area, including spray booth, is cleaned and returned to approved condition | ||
4.4 | Workplace records are completed | ||
Evidence of Performance
Interpret work order and locate and apply relevant information
Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
Identify materials used in the work process
Follow work instructions, operating procedures and inspection processes to:
minimise the risk of injury to self or others
prevent damage to goods, equipment and products
maintain required production output and product quality
Select and apply surface coatings, including the adjustment of spray equipment, to effect required coating using a minimum of two (2) different mechanical systems
Use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate material requirements
Communicate ideas and information to enable confirmation of work requirements and specifications and the reporting of work outcomes and problems, interpret basic plans and follow safety procedures
Minimise wastage of resources, including materials, time and money
Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
Evidence of Knowledge
Identification of mechanical spray system equipment, processes and procedures
Characteristics of the coatings and base materials in terms of toxicity, reactivity, flammability, required viscosity and recoatability
Effects of fumes, heat and other radiations on surface coatings
Methods to prevent contamination of surfaces during and after surface coating
Work flow in relation to spraying operations
Assessment Conditions
Assessors must:
hold training and assessment competencies as determined by the National Skills Standards Council (NSSC) or its successors
have vocational competency in the furnishing industry at least to the level being assessed with broad industry knowledge and experience, usually combined with a relevant industry qualification
be familiar with the current skills and knowledge used and have relevant, current experience in the furnishing industry.
Assessment methods must confirm consistency of performance over time rather than a single assessment event and in a range of workplace relevant contexts.
Assessment must be by observation of relevant tasks with questioning on underpinning knowledge and, where applicable, multimedia evidence, supervisor’s reports, projects and work samples.
Assessment is to be conducted on single units of competency or in conjunction with other related units of competency. Foundation skills are integral to competent performance in the unit and should not be assessed separately.
Assessment must occur on the job or in a workplace simulated facility with relevant process, equipment, materials, work instructions and deadlines.
Access is required to mechanical spray systems and equipment, spray booth, coatings and cleaning products.
Foundation Skills
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency. Detail on appropriate performance levels for each furnishing unit of competency in reading, writing, oral communication and numeracy utilising the Australian Core Skills Framework (ACSF) are provided in the Furnishing Training Package Implementation Guide.
