Specify refractory installation systems


This unit of competency covers the skills and knowledge required to specify refractory installation systems. It applies to both monolithic and block refractory installations and repairs.

This unit of competency applies to operators who are required to analyse the repair specifications; determine the scaffolding, lifting/support, access, restrictions and other systems needed to implement the installation to meet 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.

Evidence of Performance

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, data and repair specifications

determine detailed specifications covering all systems needed to implement the installation to meet specifications

monitor conformance of the installation systems to specifications and take action on non-conformances

complete project documentation and reports

communicate technical information verbally and in writing/drawings

communicate with internal and external stakeholders, including one or more of:

customer representatives

technical experts



refractory designer

refractory installer

materials and equipment suppliers


apply complex and/or theoretical mathematical calculations, statistics

solve complex problems within or arising from the repair design and/or installation.

Evidence of Knowledge

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

common installation methods

point vs. distributed loads

mechanics of levers, pulleys and jacks

structures, moments and beam reactions

tension, compression, shear and torsion

application and limitations of lifting/hoisting/supporting systems, including:

gin wheel

scaffold crane


scissor lift

fixed hoist

scaffolding design and construction

application and limitations of types of scaffolding, including:

trestle scaffold

tower scaffold

putlog scaffold

independent scaffold

working platforms

types of restrictions caused by refractory/job, including:

fragility preventing use as a footing

need to refractory clad area being used for support

lack of tie points

low coefficient of friction making it unsuitable for support

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:


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.

Foundation Skills

This section describes those required skills (language, literacy and numeracy) that are essential to performance.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range Statement

This field allows for 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.

Regulatory framework

The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used.

Applicable legislation, regulations, standards and codes of practice include:

HSE legislation, regulations and codes of practice relevant to the workplace, equipment and production processes and hazardous materials

Australian/international standards relevant to the materials being used and products being made

any relevant licence and certification requirements.

All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and such requirements the legislative requirements take precedence.

HSE hazards

Identification of HSE hazards requires consideration of:

access/egress restrictions

ventilation restrictions

moving objects/loads

cables under tension.
