Unit of competency

Modification History

Release 1. Supersedes and is equivalent to PMC557096A Specify and monitor the installation of block/precast refractories

Application

This unit of competency covers the skills and knowledge required to specify and monitor the installation of installing block, brick or precast refractories.

This unit of competency applies to operators who are required to confirm that the design aligns to refractory requirements; design and document the installation method, materials, equipment and other specifications; and monitor the installation to ensure it meets specifications.

This unit of competency applies to senior technicians or those in similar roles who are required to analyse and synthesise advanced theoretical and technical knowledge and apply independent judgement to high-level technical issues and complex problems. The individual may work in liaison with other refractory specialists or they may be the sole refractory specialist for this job or in their organisation.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Performance Evidence

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 design specifications meet refractory requirements
• determine refractory installation process to meet refractory design specifications
• plan the installation project
• develop installation specification, including:

• technical specification
• hazard controls and residual hazards
• installation schedule
• measures for monitoring critical items

• monitor the installation conformance to specifications and take action on non-conformances
• complete project documentation and reports
• communicate technical information verbally and in writing/drawings
• communicate and negotiate agreements with internal and external stakeholders, including one or more of:

• customer representatives
• technical experts
• regulators
• management
• refractory designer
• refractory installer

• materials and equipment suppliers
• contractors
• apply complex and/or theoretical mathematical calculations, statistics
• solve complex problems within or arising from the refractory design and/or installation.

Knowledge Evidence

Must provide evidence that demonstrates knowledge relevant to their job sufficient to fulfil their job role, including knowledge of:

• application and limitations of installation equipment, including:

• equipment for lifting and placing precast blocks
• temporary support for roofs and arches
• spreader jacks

• scaffolding design and construction
• calculations relevant to specifications
• project planning and management
• regulatory framework
• hierarchy of control
• hazards that may arise in the job/work environment and:

• their possible causes
• potential consequences
• appropriate risk controls.

Assessment Conditions

• The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.
• 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.
