Employability skills 

This unit contains employability skills.

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

ELEMENT 

PERFORMANCE CRITERIA 

1. Prepare for work

1.1. Workplace information, including materials application and safety information, material safety data sheets, is used to inform work practices

1.2. Characteristics of the surface and the required surface treatment are identified from work orders or instructions

1.3. Processing and application techniques, time and safety requirements are identified and used for work planning

1.4. OHS requirements, including ventilation requirements and personal protection needs, are observed throughout the work

1.5. Tools, equipment and accessories are identified and checked for safe and effective application of polyurethane, polyester and acid catalysed coatings

2. Prepare for application of materials

2.1. Surfaces are checked for contamination and correct preparation according to workplace procedures and standards

2.2. Products with surface or other faults are identified and faults repaired as appropriate

2.3. Materials required are identified and prepared for the task

2.4. Spray booths and work documentation are inspected to ensure nitro-cellulose lacquer has not been sprayed in the same booth as that used for the application of two/three part polyurethane/polyester coatings

2.5. Nitro-cellulose overspray is cleaned off booth surfaces if necessary before application of two/three-part polyurethane/polyester

2.6. Trial applications of two-part polyurethane/polyester and acid catalysed coatings are made to check equipment operation, materials consistency and viscosity

2.7. Faults and/or inconsistencies in applied coating are identified and workplace procedures for rectification and adjustment are followed

3. Apply finishing materials

3.1. Techniques for application of plural component coatings are identified and selected

3.2. Materials are applied according to job instructions, material manufacturer specifications and workplace procedures

3.3. Finished products are inspected and approved for suitability for further processing

3.4. Products which do not meet quality specifications are rectified or tagged for further investigation

4. Clean work area and maintain equipment

4.1. Equipment used 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 is cleaned and returned to approved condition

4.4. Workplace records are completed

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

• collect, organise and understand information related to coating materials, cleaning materials, work orders and safety procedures
• communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, and the reporting of work outcomes and problems
• plan and organise activities, including the preparation and layout of the worksite and the obtaining of coating equipment and materials to avoid any backtracking, workflow interruptions or wastage
• work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
• use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate paint requirements and other material requirements
• use pre-checking and inspection techniques to anticipate installation problems, avoid re-working and wastage
• use the limited workplace technology related to coating, including tools, equipment and measuring devices

Required knowledge 

• identification of application techniques
• characteristics of acid catalysed, polyurethane and polyester coatings
• the methods to prevent contamination of surfaces during and after coating
• workflow in relation to the application of polyurethane and polyester

EVIDENCE GUIDE 

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Critical Aspects of Evidence 

• Interpret work order and locate and apply relevant information
• Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
• Follow work instructions, operating procedures and inspection practices to:

• minimise the risk of injury to self and others
• prevent damage to goods, equipment and products
• maintain required production output and product quality

• Apply plural component coatings on at least three occasions, including:

• one acid catalysed
• one two-pot polyurethane
• applications, including flat, vertical and internal surfaces

• Maintain application equipment
• Work effectively with others
• Modify activities to cater for variations in workplace contexts and environment

Resource Implications 

Spray application equipment, acid catalysed, polyurethane and polyester coatings.

Method of Assessment 

Assessment methods must confirm consistency of performance over time and in a range of workplace relevant contexts.

Assessment should be by direct observation of tasks and questioning on underpinning knowledge.

Assessment may be in conjunction with assessment of other relevant units of competency.

Context of Assessment 

Assessment may occur on the job or in a workplace simulated facility with relevant process equipment, materials, work instructions and deadlines.
