Elements and Performance Criteria

1. Prepare the production area
   • Ensure the production area is clean and free from debris and waste
   • Ensure the production area is ready to receive the plaster mixture and that all equipment is ready
   • Apply stripping agent to the production facility to ensure ease of removal of the product after setting of the plaster mix
2. Mix plaster
   • Ensure that appropriate materials are available to facilitate mixing and production of plaster mix
   • Check that the mixer is clean and free from debris and that there are no obstructions or contaminants present
   • Check that the mixing equipment is safe to use
   • Introduce materials to the mixer and add temper water to specification
   • Mix the plaster for the required time and consistency
   • Discharge the mixed plaster from the mixer when it reaches the desired consistency
3. Produce fibrous plasterboard
   • Insert the fibre into the plaster mix
   • Form the plasterboard to the desired size and screed off
   • Check the plaster sheets for entrapped air or the inclusion of unwanted materials or contamination
   • Ensure product is of the required uniform thickness
   • Allow the product to dry and prepare to strip the product
4. Strip and finish the product
   • Cut the finished product to the required dimensions
   • Strip the product and inspect for imperfections and distortion
   • Hang the product for final drying
   • Remove the product from the dryer and undertake final inspection
   • Stack the product according to size and prepare for storage or shipment
5. Control hazards
   • Identify hazards in mixing and casting areas
   • Assess the risks arising from those hazards
   • Implement measures to control those risks in line with procedures and duty of care
6. Respond to problems
   • Identify possible problems in equipment or process
   • Determine problems needing action
   • Determine possible fault causes
   • Rectify problem using appropriate solution within area of responsibility
   • Follow through items initiated until final resolution has occurred
   • Report problems outside area of responsibility to designated person

Required Skills

Required skills

Required skills include recognising process conditions which 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 melting equipment reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes composition and nature of materials being utilised equipment startup and shutdown processes drying times and conditions out of specification situations distinguish between causes of faults such as incorrect raw materials equipment maladjustment contamination or poor maintenance

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 equipment be understood and that the importance of critical material properties settings and readings is known Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency 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 work area is maintained appropriately plaster is mixed to required consistency plasterboard is formed correctly finished product meets required dimensions all OHS requirements are followed problems are anticipated and appropriate action is taken ie problem fixed or reported
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 In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units
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: mixers moulds or formers lifting equipment cutting equipment drying and other equipment integral to the manufacture of fibrous plasterboard
Fibre	Fibre may include: glass fibre or other appropriate fibre
Typical problems	Typical problems may include: inappropriate material specifications introduction of contaminants inclusion of air distortion or section thickness variations
Occupational health and safety (OHS)	The identification and control of hazards and the application of OHS are 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.
