  3. Set up process
  4. Tune the process
  5. Respond to problems
  6. Control hazards

Required Skills

Required skills

Required skills include

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

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

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes

glaze properties and composition

product properties and requirements for glazing

glaze application faults

quality problems

construction and limitations of the equipment

setup and tuning of all equipment

startup and shutdown processes

glaze is application and specifications

waste minimisation techniques

process measurements required and their purpose

adjustments required and permissible to equipment or process to remain within specifications

distinguish between following causes of problems

raw materials including glaze and product

set up and tuning

mechanical

electricalinstrument

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

Competence must be demonstrated in the ability to recognise situations requiring action and then in implementing appropriate corrective action Consistent performance should be demonstrated In particular look to see that

setuptuning are completed to specifications and within timeframe

glaze application parameters are maintained within limits

glaze is applied to specification

quality is monitored to minimise wastage

startup and shutdown occur first time

signals and alarms are responded to immediately

process measurements are continually made or observed

adjustments made are completed in a timely manner to procedures

The assessment activities should include responding to a range of problems

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

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

Application of equipment

This unit includes equipment for application of glazes to ceramic or clay products, including:

automatic spray lines

robotic spray equipment

automatic dipping lines

PLCs, but not control panels

Tools and equipment

Tools and equipment may include:

changeover parts and equipment

computers

measuring and recording equipment

communication equipment

hand tools

safety clothing and equipment

Process

Process includes:

setting up and tuning equipment for startup, job change and equipment changes in preparation for production

Typical problems

Typical problems may include:

product feed to and from process

glaze composition and properties

equipment alignment

analysis of all plant data

product quality

equipment speed

taking corrective action

Plant data

Plant data may include:

test results

instrument/control panel information

data from physical senses (sight, sound and hearing)

temperatures, pressures, material flow and discharge rates and effects

variations to glaze composition or behaviour

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
