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 area, estimate glass requirements and minimise waste
• using pre-checking and inspection techniques to anticipate processing problems, and avoid re-working and wastage
• using workplace technology related to the processing of glass, including handling aids, tools, equipment, calculators and measuring devices
• modifying activities to cater for variations in workplace contexts and environment

Required knowledge includes: 

• the qualities and characteristics of glass, including hazards and handling requirements
• identification of glass processing equipment, functions and procedures
• the set-up and operation of glass processing equipment, including procedures for reporting product defects or equipment faults
• workplace safety system requirements related to glass processing
• workflow requirements in relation to glass processing

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 orders and plan processing operations
• identify the materials, patterns/plans, processes, machines, equipment and settings to undertake a glass processing task
• apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
• set up for and prepare to process glass
• 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 and use AS/NZS 4667:2000 Quality requirements for cut-to-size and processed glass
• process glass to specifications
• complete straight cuts by hand and diamond saws, simple shapes, truncated and radius corners, circles and ovals in annealed and laminated glass greater than 8 mm and up to 1.0 m2
• rough and smooth arrise annealed and laminated glass greater than 8 mm by hand and up to 0.5 m2
• drill holes with diamond drills in annealed glass greater than 8 mm and up to 0.5 m2
• calculate the cost of glass and edgework

• 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 sheet/product greater than 8 mm thick
• processing facilities/equipment, such as cutting equipment and glass edging/drilling equipment
• work table
• appropriate work area
• work orders
• appropriate safety and personal protective equipment.

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.
