Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
This describes the essential skills and knowledge and their level required for this unit.
Application of an operational knowledge of the materials, equipment and process sufficient to recognise out of specification products, process problems and materials faults. For example, excess resin will only add weight and weaken the finished product. Therefore care needs to be taken to ensure the correct resin to fibre ratio is used.
Knowledge of organization procedures, relevant regulatory requirements, and the ability to implement them within appropriate time constraints and work standards.
Application of the knowledge of managing risks using the hierarchy of controls applied to the hand lay up process. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup.
Knowledge of and skills in the operation of hand lay up equipment and the main components sufficient for consistent production of quality products including:
production workflow sequences and materials demand
accurately monitoring equipment and product quality
understanding the potential effects of variations in raw materials and equipment in relation to quality of product
waste management and understanding the importance of reusing non-conforming products wherever possible
correct selection and use of equipment, materials, processes and procedures
identify factors which may affect product quality or production output and appropriate remedies.
setting up moulds
preparation of resins, including mixing as required
preparation of fibre reinforcement, including cutting and trimming
use of composites materials, including gel coats, resins and fibres
methods of application of composite materials to the mould by hand lay up.
Competence also includes the ability to:
plan own work, including predicting consequences and identifying improvements
identify when the operator is able to rectify faults, when assistance is required and who is the appropriate source for assistance
identify and describe own role and role of others involved directly in the moulding process.
Language, literacy and numeracy requirements
This unit requires the ability to read and interpret typical product specifications, job sheets, procedures, material labels and safety information as provided to operators.
Writing is required to the level of completing workplace forms.
Numeracy is required to the level of reading tables of figures and graphs (and applying the resultant information), using formula percentages/ratios to determine the required mass of an additive (catalyst, pigment etc.) and similar manipulations and interpretation.
The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any 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.
Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.
Context
This competency unit includes the use of equipment and materials to form composite products using hand lay up processes. It includes the operation of all relevant additional equipment where that equipment is integral to the hand lay up process.
Procedures
All operations are performed in accordance with procedures.
Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.
Tools and equipment
This competency includes use of equipment and tools such as:
open moulds for composite products
hand mixing equipment and stirrers
knives and cutters to trim fibres
hand application tools, rollers, brushes, etc
relevant personal protective equipment.
Hazards
Typical hazards include:
hazardous materials and vapours
manual handling hazards
fire hazards due to flammable nature of resins used
knife hazards
glass (and other) fibre hazards (inhalation and skin penetration)
slip hazards (spilled resin).
Problems
Respond to/rectify 'non-routine problems' means 'apply known solutions to a limited range of predictable problems'. Typical process problems may include:
cracks, dents or imperfections of the mould
incorrect resin ratios
contamination of materials
shifting of fibres before resin laid
stacking of fibre and resin sequence problems.
Typical product problems may include:
voids
poor surface finish
colour contamination
release from mould damage.
Appropriate action for non-routine problems may be reporting to designated person or other action specified in the procedures.
Variables
Key variables to be monitored include:
ambient temperature
air flow/ventilation rate
viscosity of resin
time since resin mixed vs pot life of mix
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
