This section describes the skills and knowledge required for this unit.

Required skills include: 

• collecting, organising and understanding information related to work orders, basic plans and safety procedures
• using communication skills to the level required to confirm work requirements and specifications; communicate effectively regarding work requirements with supervisors, other workers and customers; report work outcomes and problems; and relate to people from a range of social, cultural and ethnic backgrounds, and of varying physical and mental abilities
• using literacy skills to the level required to understand information related to work orders, including common industry terminology, plans and safety procedures; prepare reports; and interpret technical information and specifications
• planning and organising activities, including the preparation and layout of the work area and the obtaining of equipment and materials to avoid any backtracking, workflow interruptions or wastage
• working with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
• using mathematical ideas and techniques to correctly complete measurements, calculate work requirements, optimise glass sizes for handling and processing, and assemble required materials
• using pre-checking and inspection techniques to plan work, and avoid re-working and wastage
• using the workplace technology related to the operation of glass toughening equipment
• modifying activities to cater for variations in workplace contexts and environment

Required knowledge includes: 

• correct procedures for the set-up, operation and operator maintenance of glass toughening equipment
• workflow requirements relating to the operation of glass toughening equipment
• workplace procedures for the reporting of material, product or equipment faults
• characteristics of materials used and uses of products produced in the glass toughening process
• correct identification of relevant equipment, processes and procedures
• workplace safety system requirements related to the operation of glass toughening equipment

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

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

Assessors must be satisfied that the candidate can competently and consistently:

• interpret work order/job instruction and locate and apply relevant information to operate glass toughening equipment
• plan the conduct of glass toughening operations
• set up, operate, monitor and perform operator maintenance of glass toughening equipment
• apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
• follow work instructions, operating procedures and inspection practices to:

• minimise the risk of injury to self and others
• prevent damage to goods, equipment and products
• maintain required production output and product quality

• as a minimum:

• identify the features of the glass toughening process, including the principles, purpose and properties of toughened glass
• identify the procedures required in the glass toughening process
• perform pre-inspection and preparation procedures on glass for toughening
• safely load and operate a glass toughening furnace
• perform testing, classification and marking of toughened glass in accordance with AS/NZS 2208:1996 Safety glazing materials in buildings

• work effectively with others.

Context of and specific resources for assessment

The application of competency is to be assessed in the workplace or realistically simulated workplace.

Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints.

Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context.

Assessment is to comply with relevant regulatory or Australian Standard requirements.

The following resources should be made available:

• glass toughening equipment
• workplace operating procedures
• unprocessed materials
• personal protective equipment
• an appropriate work area.

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the LMF02 Furnishing Industry 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 must be by direct observation of tasks and include questioning on underpinning knowledge to ensure 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.
