REQUIRED SKILLS AND KNOWLEDGE 

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

Required skills 

• collect, organise and understand information related to work orders, basic plans, and safety procedures
• communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with work supervisor, other workers and customers, and the reporting of work outcomes and problems
• plan and organise activities including the preparation and layout of the work area and the obtaining of equipment and materials to avoid any back tracking, workflow interruptions or wastage
• work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
• use mathematical ideas and techniques to correctly complete measurements, calculate work requirements, optimise glass sizes for economical cutting and assemble required materials
• use pre-checking and inspection techniques to plan work, avoiding re-working and wastage
• use the limited workplace technology related to the construction/repair of leadlight panels

Required knowledge 

• end use of the panel and required safety, quality and structural standards
• characteristics, including the hazards and workplace safety system requirements associated with the materials used in leadlight panel construction
• operation of tools and equipment used in constructing/repairing leadlight panels
• processes and procedures involved in the construction/repair process
• the impact of design features of the leadlight panel on purpose, materials and construction
• relevant Australian Standards

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.

Critical aspects of evidence 

• Interpret work order/job instruction to identify requirements and plan the process to construct/repair leadlight panels
• Select and use appropriate materials and processes for the panel being constructed/repaired
• 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, demonstrate the ability to:

• construct leadlight panels
• measure openings for leadlight panels
• design, including construction of cartoon
• construct templates
• identify and select materials, including glass and lead came
• cut basic and complex shapes in clear, patterned and coloured glass
• lead up, flux and solder
• weatherproof, cement, pick and polish
• glaze, including putty facing and beading up
• may include reinforcement bar installation

• Repair leadlight panels:

• remove leadlight from opening to be repaired
• construct templates, cartoons and rubbings
• identify and select replacement materials
• disassemble lead and broken glass panels
• cut glass to suit
• lead up, weatherproof, cement, pick and polish
• reglaze repaired leadlight panel

• Work effectively with others
• Modify activities to cater for variations in workplace contexts and environment

Resource implications 

Appropriate leadlighting materials, work area, work order, specifications, tools, personal protective equipment, equipment and consumables.

Method of assessment 

Assessment methods must confirm consistency of performance over time and in a range of workplace relevant contexts.

Assessment should be by direct observation of tasks and questioning on underpinning knowledge.

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

Context of assessment 

Assessment may occur on the job or in a workplace simulated facility with relevant leadlight construction/repair equipment, materials, work instructions and deadlines.
