Elements and Performance Criteria

RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Unit context
This unit covers work involving the set up, operation and monitoring of insulated glass unit manufacturing equipment, including quality testing of IGU
Work requires individuals to demonstrate discretion, judgement and problem solving skills in the set up and operation of insulating glass unit manufacturing machines
Work is carried out in accordance with statutory requirements, environment legislation, manual handling procedures and relevant regulations and organisation insurance requirements
OH&S requirements may include legislation, standards, building codes, material safety management systems and local safe operating procedures
Work is generally performed individually, with general supervision and may be part of a production process
Insulated glass units (IGU)
Insulated glass units are two sheets of glass that are separated by a spacer, sealed to form an airtight unit
Tools and equipment are to include:
cutting equipment (saws, etc.)
spacer preparation equipment (appropriate size)
sieve machine and desiccant equipment
primary seal equipment
secondary seal equipment
basic hand tools (screwdriver, scraper, etc.)
mechanical handling equipment
Materials are to include but are not limited to:
customer requirements for glass (annealed
toughened or laminated)
corner keys for spacers
appropriate primary (polyisobutylene) and secondary sealant (polysulphide) and separation paper
Personal protective equipment
Personal protective equipment is to include that prescribed under legislation, regulations and enterprise practices and procedures. It may include:
gauntlets
gloves
safety glasses
hard hats
safety footwear
aprons
hearing protection
overalls
Information and procedures
Workplace procedures relating to the setting up and operation of insulated glass unit manufacturing machinery
Machine manufacturer specifications and operational procedures
Workplace procedures relating to the handling and movement of glass
Work instructions including job sheets, cutting lists, plans, drawings and designs
Safety standards include personal protective equipment, OHS regulations and enterprise requirements
Australian Standards:
AS1288 Glass in buildings, selection and installation.
AS2208 Safety glazing materials in buildings
AS4666 Insulating glass units
AS4667 Quality requirements for cut to size and processed glass

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 the operation of insulated glass unit manufacturing equipment
Plan the conduct of insulated glass unit manufacturing operations
Set up, operate and monitor insulated glass unit (IGU) manufacturing equipment and the quality testing of IGU
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, set up, manufacture and conduct the appropriate quality testing of five differing IGU patterns to the capacity of the IGU machine
Work effectively with others
Modify activities to cater for variations in workplace contexts and environment

Resource implications
Insulated glass unit manufacturing equipment, 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 insulated glass unit manufacturing equipment, materials, work instructions and deadlines.
