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:

identify and use AS4667 Quality requirements for cut to size and processed glass

complete straight cuts by hand and diamond saws, simple shapes, truncated and radius corners, circles and ovals in annealed and laminated glass greater than 6.38 mm and up to 1.0 m 2

Work effectively with others

Modify activities to cater for variations in workplace contexts and environment

Resource implications

Glass sheet/product, processing facilities/equipment (such as cutting equipment and glass edging equipment), table, work area, work orders and appropriate safety and personal protection equipment.

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 glass processing equipment, materials, work instructions and deadlines.

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