Required Skills and Knowledge

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 handling and processing and assemble required materials use pre-checking and inspection techniques to plan work, avoiding re-working and wastage use the workplace technology related to the operation of glass silvering equipment
Required knowledge
procedures for the planning, preparation, operation and completion of glass silvering operations workflow in relation to the operation of glass silvering equipment workplace procedures for the reporting of material, product or equipment faults relevant Australian Safety Standards identify, handle and store hazardous chemicals characteristics of materials used and uses of products produced by glass silvering operations workplace safety system requirements related to the operation of glass silvering equipment

Evidence Guide

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 and locate and apply relevant information to operate glass silvering equipment Plan and prepare for the conduct of glass silvering operations Conduct glass silvering operations 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: prepare silvering formulae perform equipment checks set up and prepare silvering equipment clean and prepare glass for silvering apply tinning, silvering and copper solutions on glass dry and apply packing paint strip, buff, clean, prepare and re-silver mirrors handle and store mirrors clean solution tanks, lines, spray guns and equipment after use Work effectively with others Modify activities to cater for variations in workplace contexts and environment
Resource implications	Glass silvering equipment, demineralised water, acid, silvering chemicals, backing paint, workplace operating procedures, unprocessed materials, personal protective equipment and an appropriate work area.
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 silvering equipment, materials, work instructions and deadlines.
