Elements and Performance Criteria

1. Prepare for work
   • Work requirements are determined from work instructions
   • Work health and safety (WHS) requirements relevant to operating insulating glass equipment, including personal protective equipment, are observed throughout the work
   • Work sequence is planned in a logical order to suit the job requirements and workplace procedures
   • Tools, equipment and materials are selected and checked prior to use to ensure they are appropriate for the work, of the required quality, serviceable and in a safe condition
   • IGU machines, tools and equipment are identified and checked for safe and effective operation, including emergency stops, gauges, guards and controls
   • Procedures for checking quality of materials and items produced, rating system compliance, working condition of equipment, and quality requirements for each stage of the IGU manufacturing process are identified
   • Communication with others involved with the work is established and maintained to ensure efficient work flow coordination, personnel cooperation and safety throughout the insulated glass manufacturing process
2. Set up equipment
   • Machine settings and adjustments are made in accordance with job requirements and machine and tool manufacturer instructions
   • IGU spacers are cut and sorted into order of run in accordance with workplace procedures
   • The desiccant hygroscopic substance that induces or sustains a state of dryness (desiccation) to be used in process is tested in accordance with industry standards and workplace practices
   • Trial runs are conducted to check machine operation, accuracy and quality of finished work, and any necessary adjustments made to machine settings
3. Conduct IGU manufacturing operations
   • Glass sheets are loaded into IGU machine using the appropriate mechanical handling equipment
   • IGU spacers are assembled in accordance with specification/order and workplace procedures
   • IGU machine is operated to wash and dry glass and to press the unit
   • Unit is unloaded from IGU machine and relocated for sealing using appropriate mechanical handling equipment in accordance with workplace practices
   • Primary and secondary seal equipment is operated in accordance with workplace procedures
   • Testing for water vapour (dewpoint) and integrity of sealing (moisture) is conducted in accordance with workplace procedures
   • Serviceable units are labelled and stored in accordance with industry standards and workplace procedures, with items not meeting quality requirements being discarded or returned for reprocessing in accordance with workplace procedures
4. Complete work and maintain equipment
   • Work area is cleaned and rubbish disposed of, as appropriate
   • IGU machine is cleaned and inspected for serviceability in accordance with workplace procedures
   • Unserviceable equipment is tagged and faults identified in accordance with workplace procedures
   • Equipment and tooling are maintained in accordance with workplace procedures
   • Tools, equipment and unused materials are removed and stored appropriately
   • Documentation is completed in accordance with workplace requirements

Performance Evidence

Interpret work order and locate and apply relevant information

Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment

Identify materials used in the work process

Follow work instructions, operating procedures and inspection processes to:

minimise the risk of injury to self or others

prevent damage to goods, equipment and products

maintain required production output and product quality

Prepare, set up, manufacture and conduct the appropriate quality testing of five (5) differing IGU patterns to the capacity of the IGU machine

Use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate material requirements

Communicate ideas and information to enable confirmation of work requirements and specifications and the reporting of work outcomes and problems, interpret basic plans and follow safety procedures

Avoid backtracking, work flow interruptions or wastage

Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
