Elements and Performance Criteria

  1. Prepare formation equipment
  2. Fine tune forming processes
  3. Form the products
  4. Rectify routine problems
  5. Control hazards.

Required Skills

Required skills

Required skills include

recognising process conditions which will lead to out of specification production and taking appropriate action

implement the enterprises standard procedures and work instructions and relevant regulatory requirements within appropriate time constraints and in a manner relevant to the operation of the forming equipment

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes

composition and nature of the glass

setupchangeover of equipment

startup and shutdown processes

construction and limitations of the equipment

out of specification situations

quality problems include

poor optics

excessive breakage

nonuniform break pattern

excessive bow

scratches

poor glass shape

distinguish between causes of faults such as

raw materials

equipment

types of defectsfaults

Evidence Required

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

Overview of assessment

The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency

Critical aspects for assessment and evidence required to demonstrate competency in this unit

It is essential that the reheating equipment be understood and that the importance of critical material properties settings parameters and readings is known Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action

Consistent performance should be demonstrated In particular look to see that

temperatures are maintained within limits

startup and shutdown occur first time

signals and alarms are responded to immediately

process measurements are continually made observed and interpreted

quality is maintained to customer specifications

Context of and specific resources for assessment

Assessment will require access to an operating plant over an extended period of time or a suitable method of gathering evidence of operating ability over a range of situations

Assessment will occur over a range of situations which will include disruptions to normal smooth operation

Simulation or case studiesscenarios may be required to allow for timely assessment of parts of this unit of competency Simulation should be based on the actual plant and will include walkthroughs of the relevant competency components A bank of scenarioscase studieswhat ifs and questions will be required to probe the reasoning behind observable actions

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units

Individual enterprises may choose to add prerequisites and corequisites relevant to their processes

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed


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.

Procedures

All operations are performed in accordance with standard procedures and work instructions

Equipment

Equipment may include:

bath

ancillary equipment

computers

measuring recording equipment

communication equipment

hand tools

safety clothing and equipment

Typical problems

Typical problems may include:

temperature and pressure problems

equipment problems

quality problems

loss of ribbon

Occupational health and safety (OHS)

All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence
