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

Assessment of this unit should include demonstrated competence in a workplace based project or a simulated workplace project.

Access should be available to all normally accessed tables, data etc which would be available to and used by a competent refractory specialist performing this assignment.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Competence must be demonstrated in the ability to select an appropriate material and write the required specification.

Context of and specific resources for assessment

Assessment may occur on the job or in an appropriately simulated environment. Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

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.

Method of assessment

Assessment must satisfy the endorsed assessment guidelines of the Manufactured Mineral Products Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.

Assessment methods which include direct observation of tasks should also include questioning on underpinning knowledge to ensure its correct interpretation and application.

Assessment may be applied under project related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

Required skills

Required skills include:

solving problems

communicating at all levels

using organisation knowledge system

investigating

analysing

interpreting data

negotiating

calculating

technical reporting

Required knowledge

Required knowledge includes:

properties of all common refractory materials

scaffolding systems and regulations

lifting/hoisting/supporting systems and regulations

structures, moments and beam reactions

point vs. distributed loads

mechanics of levers, pulleys and jacks

tension, compression, shear and torsion

relevant terms

relevant calculations

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. 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.

Restrictions caused by refractory/ job

Restrictions caused by refractory include:

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

Types of scaffold

Types of scaffold include:

trestle scaffold

tower scaffold

putlog scaffold

independent scaffold

working platforms

HSE hazards

HSE hazards may include:

access/egress restrictions

ventilation restrictions

moving objects/loads

cables under tension

Hazard control

Appropriate hazard control should be determined by:

applying the hierarchy of control

Lifting supporting means

Lifting supporting means include:

gin wheel

scaffold crane

elevator

scissor lift

fixed hoist
