2 | Remove surface coatings | 2.1 | Sequence of work is identified for the removal operation, including the efficient and effective use of chemicals to be used |
2.2 | Equipment, chemicals and abrasives are used within manufacturer specifications and workplace procedures | ||
2.3 | Surface coating is removed according to workplace procedures and specifications | ||
2.4 | Surfaces are inspected to ensure removal of surface coating is to workplace standard | ||
2.5 | Defects found after removal of surface coating are dealt with and/or reported in accordance with workplace procedures | ||
3 | Clean work area and maintain equipment | 3.1 | Item is stored and labelled ready for next process |
3.2 | Equipment is cleaned and inspected for serviceable condition and stored appropriately | ||
3.3 | Unserviceable equipment is tagged, faults are identified and appropriate personnel are informed | ||
3.4 | Chemicals and other materials are stored or disposed of correctly according to regulations | ||
3.5 | Work area is cleaned ready for next process or task | ||
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
Remove surface coating from timber and metal surfaces and apply appropriate techniques to remove coatings from flat, vertical, carved and curved surfaces, using a minimum of four (4) different removal techniques and materials
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
Work flow in relation to the removal of surface coatings
Types, properties and characteristics of coatings
Coating removal techniques, materials, applications and limitations
Material safety management systems
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 a range of surfaces to be removed, removal methods, tools, equipment and consumables.
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.
Range Statement
Specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Range is restricted to essential operating conditions and any other variables essential to the work environment. | |
