Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and demonstrate the ability to:
analyse and interpret technical reports, technical specifications and data
confirm requirements for refractory end use conditions, including:
surface temperature of refractory
required temperature gradient through refractory/outside surface temperature
chemical condition (e.g. pH)
mechanical condition (e.g. impingement)
temperature or other cycling
communicate technical information verbally and in writing/drawings
communicate with internal and external stakeholders, including one or more of:
customer representatives
technical experts
regulators
management
refractory material selector
refractory installer
determine optimum refractory installation by evaluating criteria, including:
alignment to technical requirements of the end use
preliminary design calculations
installation, repair or removal issues
cost (material, installation, repair, life cycle)
health, safety and environmental (HSE) risks (installation, use, repair, removal and disposal)
relative benefits/costs/risks of block/precast, monolithic/castable, gunite/shotcrete, refractory coating and multilayer (e.g. hard face over insulating refractory) refractory linings
negotiate with relevant stakeholders and document agreed requirements and design and technical specifications
apply complex and/or theoretical mathematical calculations
solve complex problems to determine design and specification which best deliver the technical requirement at the lowest cost and the least HSE risk
develop technical drawings manually or with computer-aided drafting (CAD).
Must provide evidence that demonstrates knowledge relevant to their job sufficient to fulfil their job role, including knowledge of:
properties of all common refractory materials
typical limitations and applications of all common refractory systems
installation methods and their advantages, disadvantages, typical uses and limitations
heat transfer calculations (resistances in series and parallel)
structural calculations (beam, column, arch, strength of refractory materials, and physical properties of refractory materials)
thermal expansion (calculation of and allowance for)
refractory anchors, types, uses and selection
refractory installation methods and their impact on design
common refractory repairs and their impacts on design
methods of reuse, recycling and disposal of refractories at the end of their life and the differences for different types of refractory systems
critical refractory specifications
regulatory framework
hierarchy of control
hazards that may arise in the job/work environment and:
their possible causes
potential consequences
appropriate risk controls.
The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.
It may be appropriate to assess this unit in conjunction with:
PMC557090 Select refractory materials for an application.
The collection of performance evidence is best done from a report and/or folio of evidence drawn from:
a single project which provides sufficient evidence of the requirements of all the elements and performance criteria
multiple smaller projects which together provide sufficient evidence of the requirements of all the elements and performance criteria.
A third-party report, or similar, may be needed to testify to the work done by the individual, particularly when the project has been done as part of a project team.
Assessment should use a real project in an operational workplace. Where this is not possible or where personal safety or environmental damage are limiting factors assessment must occur using a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessment in a simulated environment should use evidence collected from demonstration of skills and one or more of:
walk-throughs
pilot plant operation
industry-based case studies/scenarios
‘what ifs’.
Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
In addition the assessor or anyone acting in subject matter expert role in assessment shall demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they shall assess with a subject matter expert who does meet these requirements.
Technical competence can be demonstrated through one or more of:
relevant VET or other qualification/Statement of Attainment
appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions
appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions
Currency can be demonstrated through one or more of:
being currently employed undertaking the type of work being assessed
being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures
having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment
conducting on the job training/assessments of the type of work being assessed
being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work.
