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. Bold italicised wording, if used in the performance criteria, is detailed below. 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) may also be included.
General and detailed refractory plans include:
detailed plans show aspects and sections of the structure in greater detail than the general plan
general plans show the entire structure to be constructed.
Signs and symbols relate to:
assembly of completed parts of the structure
dimensions and scales
materials to be used
particular views of the structure
quality control requirements
sections of the structure
tolerances.
Notes include:
details of Australian standards to be complied with
quality control requirements to be followed and documented
requirements for samples of castables to be taken.
Materials include:
castables
different types of insulation materials, including insulation boards and bricks
fire bricks
fire clay
stainless steel joints.
Safety precautions include:
environmental precautions, such as the operation of an extraction system to filter dust and fumes
use of personal protective clothing, including:
disposable overalls
dust masks
eye and ear protection
gloves
respirator
steel toe capped shoes.
OHS requirements include:
handling materials
protective clothing and equipment
use of tools and equipment
working platforms and scaffolding
workplace environment and safety.
Tools and equipment include:
clay mixer
measuring tapes and rules
mortar boards
rubber mallets and scutches
straight edges
string lines
trowels.

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.
Overview of assessment
This unit of competency could be assessed by carrying out relevant preparations for refractory work. It should include analysis and interpretation of the plans and specifications, demonstrated understanding of all aspects detailed in the plans, implementation of safety precautions and correct selection of relevant materials and equipment.
This unit of competency can be assessed in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
demonstrate understanding of the purpose and application of refractory bricklaying
comply with OHS regulations applicable to workplace operations
use safe and effective procedures to handle hazardous materials
apply organisational quality procedures and processes within context of constructing or repairing structures employing refractory materials
read and interpret two-dimensional refractory plans and specifications
select and use processes, tools and equipment appropriate to job requirements
prepare materials and samples in accordance with job requirements
identify typical faults and problems with materials and equipment that occur and necessary action to rectify
communicate effectively with others to ensure safe work site operations.
Context of and specific resources for assessment
This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints.
Assessment of essential underpinning knowledge will usually be conducted in an off-site context.
Assessment is to comply with relevant regulatory or Australian standards' requirements.
Resource implications for assessment include:
materials appropriate to refractory brickwork
plant, tools and equipment relevant to refractory brickwork.
Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.
Method of assessment
Assessment methods must:
satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package
include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
reinforce the integration of employability skills with workplace tasks and job roles
confirm that competency is verified and able to be transferred to other circumstances and environments.
Validity and sufficiency of evidence requires that:
competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice, with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge
all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence.
Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.
Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.
