  4. Dry/cure products
  5. Finish green products
  6. Rectify routine problems

Required Skills

Required skills

Required skills include

reading from the production schedule

stacking greenware to allow efficient drying and curing

recognising conditions which will lead to out of specification product

implementing the enterprises procedures within time constraints and in a manner relevant to the correct use of the equipment

conveying information relevant to the operation clearly and effectively

maintaining appropriate levels of quality assurance

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes

surface finish requirements and terms

nature and purpose of the dryingcuring stage

importance of correct moisture content

importance of correct temperature and air circulation

consequences of poor stacking

underlying causes of faults such as precipitated by

dryercuring kiln

air flowtemperature

materials

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

greenware is ready for next stage of the process

drying achieves the specified moisture content

curing achieves the specified strength

dryingcuring area loaded to requirements

temperature and humidity are within limits

product waste levels are low

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 competency unit eg those parts referring to safety of equipment Simulation should be based on the actual plant and will include walkthroughs of the relevant competency components A bank of scenarioscase studieswhat ifs will be required as will a bank of questions which will be used to probe the reasoning behind the 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 appropriate to the work being performed and must take into consideration the language and literacy capacity of the candidate


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

Greenware and green products

Greenware and green products may include:

clay and ceramics products prior to firing

fibre reinforced cement products prior to autoclaving

concrete products such as masonry curing

Equipment

Equipment may include:

hand tools

templates

drying area, cabinets, tunnel, curing kiln

transfer cars, kiln cars, trolleys, shelving or racks

temperature measuring equipment

moisture measuring equipment (e.g. infra-red moisture meter)

Finishing

Finishing includes operations, such as:

brushing

dressing

fettling

linishing

sanding

stacking

edge trimming

Typical problems

Typical problems may include:

inspecting and finishing to ensure surfaces are to specification

ensuring moisture content is within requirements

ensuring product strength has been obtained

temperature and humidity control

distribution of product in drying/curing area

Occupational health and safety (OHS)

The identification and control of hazards and the application of OHS is to be in accordance with current, applicable legislation and regulations, and company procedures. All work is carried out at all times in accordance with these requirements
