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 knowledge of the materials, equipment and process sufficient to recognise out of specification products, process problems and materials faults.
Knowledge of the enterprise's procedures and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.
Knowledge of and skills in the operation of blown film equipment and main components sufficient for consistent production of quality products including:
operation of blown film equipment and components;
production workflow sequences and materials demand;
reasons for checking process control panels and reporting readings which do not conform to the work instructions;
approved hazard control and safety procedures and the use of PPE in relation to handling materials,
equipment operation and cleanup;
potential effects of variations in raw materials and equipment operation in relation to quality of product; waste management and importance of reusing non-conforming products wherever possible;
correct selection and use of equipment, materials, processes and procedures
plan own work including predicting consequences and identifying improvements
monitor equipment operation and product quality
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 process
identify factors which may affect product quality or production output and appropriate remedies
use PPE, safely handle products and materials, read relevant safety information and apply safety precautions appropriate to the task
pause equipment, or shut down equipment in abnormal circumstances
explain the effect of unauthorised or emergency shutdown in relation to safety and production requirements
distinguish between possible causes of routine faults such as: incorrect quantity of materials; contaminated materials/additives; equipment faults; die/tool damage; wrong raw materials/additives; incorrect quantity of materials/additives; machine failure.
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.
Basic numeracy is required, eg, to determine that two 25 kg bags are needed to make up a requirement for 50 kg.
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 applies to operators working either independently or as part of a work team.
Procedures:
All operations are performed in accordance with procedures.
Procedures means 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
extruder
bubble guides and rollers
film rollers, slitting, trimming and winding gear
coolers, heaters and ancillary equipment
hand tools, knives, adjustment tools
relevant personal protective equipment
treatment unit.
Hazards:
Typical hazards include
high air velocities
high voltage corona treatment systems
sharp knives
high towers manual handling
fumes, humidity, air temperatures, radiant heat, hot dies
stationary and moving machinery, parts and components.
Problems:
'Respond to routine problems' means 'apply known solutions to a limited range of predictable problems'.
Typical process and product problems may include
extruder control
contamination
alignment and control of trimming and winding gear
raw material contamination, wrong grade, variations of polymer properties.
Variables:
Key variables to be monitored include
equipment pressures and temperatures
material specifications
ambient temperature
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.
