Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Regulatory framework	The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used. Applicable legislation, regulations, standards and codes of practice include: health, safety and environmental (HSE) legislation, regulations and codes of practice relevant to the workplace, equipment and production processes and hazardous materials Australian/international standards relevant to the materials being used and products being made any relevant licence and certification requirements. All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and such requirements the legislative requirements take precedence.
Equipment	Equipment includes the setting and trial of one or more of: rotational moulding machines: rock and roll clamshell vertical or up and over rotational shuttle swing arm carousel thermoforming: wood patterns moulds cast aluminium moulds machined aluminium moulds composite moulds complex moulds vacuum forming systems similar systems.
Operational requirements	Operational requirements include one or more of: mould set up and adjustment machine speed ratios for rotation cycle time external temperatures humidity type of heating used cooling rates product quality measures any other specified requirement.
Procedures	All operations must be performed in accordance with relevant procedures. Procedures are written, verbal, visual, computer-based or in some other form, and include one or any combination of: emergency procedures work instructions standard operating procedures (SOPs) safe work method statements (SWMS) formulas/recipes batch sheets temporary instructions any similar instructions provided for the smooth running of the plant.
Hazards	Hazards must be identified and controlled. Identifying hazards requires consideration of: material spills or leaks hazardous products and materials manual handling hazards stationary and moving machinery machinery hazards protrusions or obstructions slippery surfaces smoke, dust, fumes, vapours or other atmospheric hazards humidity, air temperatures and radiant heat noise, light and energy sources other hazards that might arise.
Causes of faults	Causes of faults include one or more of: materials heat equipment adjustment equipment set-up.
Problems/solutions	Problems/solutions include one or more of: selecting the right tools for a new job using new and untried moulds adapting the process to the new product and die/tool observing the process to obtain useful trial data comparing the product to the desired specification determining the cause of non-compliances.
