Elements and Performance Criteria

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.
Context
This competency applies to a variety of internal and external work environments served by the rubber industry and includes work done in a production facility and on site.
This competency unit includes the use of manual handling of lining materials, the use of scaffolding and can involve activities within the definition of 'confined space'. (Note that separate competencies, and/or licensing requirements may apply for these activities.)
Lining materials includes rubber compounds which includes green (uncured) sheets, pre-cured rubber sheets and other polymer sheets. Lining or lagging will generally be of metal items, but may include application to composites, concrete and other non-metallic structures, vessels, pulleys or plant items.
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:
hand tools (eg spanners, wrenches and hammers)
knives and other trimming devices
hoists/lifting equipment not requiring any special permits or licences
rollers and other surface compression tools
ventilation equipment (eg fans)
relevant personal protective equipment, including 'breathers' as required.
Hazards
Typical hazards include:
spills
dusts/vapours
hazardous materials (eg adhesives, solvents and other chemicals)
manual handling hazards
knife hazards
noxious, toxic fumes or inflammable fumes
confined spaces
working at heights.
Problems
'Respond to routine problems' means 'apply known solutions to a limited range of predictable problems'. Typical process and product problems may include:
variations in materials
incorrectly cut material shapes
contamination of materials
contamination of the surfaces to be lined or lagged
physical size and complexity of some components
entrapped air
gaps between lining segments
inappropriate laps or joins.
Variables
Key variables to be monitored include:
compatibility of materials, adhesives, solvents and cleaning agents
cleanliness and condition of lining/lagging materials
affect of surface condition of the component on the quality of the lining/lagging.

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, required skills and knowledge, the Range Statement and the Assessment Guidelines for this Training Package.
Overview of assessment
A holistic approach should be taken to the assessment.
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:
recognise the importance of material properties and qualities
apply approved procedures
take appropriate action to resolve faults or report faults to appropriate personnel
explain and implement emergency evacuation procedures.
Consistent performance should be demonstrated. For example, look to see that:
rubber layup production standards are met consistently
communication is timely and effective
work instructions are read and interpreted correctly
problems are identified and appropriate action is taken (ie, the problem is fixed or reported)
all safety procedures are followed.
Assessment method and context
Assessment will occur on industrial equipment and will be undertaken in a work-like environment.
Competence in this unit may be assessed:
by use of an appropriate, industrial lining/lagging situation
in a situation allowing for the generation of evidence of the ability to respond to problems
by using a suitable simulation and/or a range of case studies/scenarios
through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
