Foundation Skills

This section describes those required skills (language, literacy and numeracy) that are essential to performance.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range of Conditions

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 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.

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
  • SOPs
  • safe work method statements (SWMS)
  • formulas/recipes
  • batch sheets
  • temporary instructions
  • any similar instructions provided for the smooth running of the plant.

Tools and equipment 

Tools and equipment will be selected as required from:

  • measurement equipment
  • hand carts and trolleys
  • basic hand tools required for opening of material packaging
  • hoists/lifting equipment not requiring any special permits or licences
  • mixing spatulas or paddles
  • portable electrical paddle mixers
  • relevant personal protective equipment (PPE).

Hazards 

Hazards must be identified and controlled. Identifying hazards requires consideration of:

  • weight, shape, volume of materials to be handled
  • hazardous products and materials
  • sharp edges, protrusions or obstructions
  • slippery surfaces, spills or leaks
  • heat, smoke, dust, vapours or other atmospheric hazards
  • electricity
  • gas
  • gases and liquids under pressure
  • structural hazards
  • equipment failures
  • machinery, equipment and product mass
  • other hazards that might arise.

Routine problems 

Routine problems must be resolved by applying known solutions.

Routine problems are predictable and include one or more of:

  • incorrect material composition
  • over or under mixing
  • broken mixing equipment
  • temperature variations
  • variations in materials
  • contamination of materials
  • variations in setting times.

Known solutions are drawn from one or more of:

  • procedures
  • training
  • remembered experience.

Non-routine problems must be reported according to according to relevant procedures.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and demonstrate the ability to:

  • read and interpret procedures, job specifications, material labels and safety data sheets (SDS)
  • select and use materials, tools and equipment to meet job specifications
  • combine and mix ingredients according to procedures
  • monitor key variables, including:
  • atmospheric conditions
  • sequencing of material additions to the mix
  • volumes/mass of materials being mixed
  • mixing time
  • amount of moisture
  • product quality
  • identify hazards and apply relevant hazard controls
  • implement emergency shutdown procedures
  • apply safety procedures

·  apply housekeeping procedures

·  apply waste management procedures

  • recognise routine and non-routine problems
  • identify when the operator is able to rectify problems, when assistance is required and who is the appropriate source for assistance

Assessment Conditions

  • The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.
  • In all plants it may be appropriate to assess this unit concurrently with units such as:
  • teamwork
  • communication.
  • The collection of performance evidence:
  • should occur over a range of situations which include typical disruptions to normal, smooth operations and provide for demonstration of responding to problems
  • will typically include a supervisor/third-party report or other evidence, focusing on consistent performance and problem recognition and solving. A supervisor/third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency
  • must include the use of industry appropriate materials, tools, equipment, data and documentation
  • may use industry-based simulation for all or part of the unit particularly where safety, lack of opportunity or significant cost is an issue.
  • Assessment should occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
  • Assessment in a simulated environment should use evidence collected from demonstration of skills and one or more of:
  • walk-throughs
  • pilot plant operation
  • industry-based case studies/scenarios
  • ‘what ifs’.
  • Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews.
  • Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
  • Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
  • The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
  • Foundation skills are integral to competent performance of the unit and should not be assessed separately.
  • Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
  • In addition the assessor or anyone acting in subject matter expert role in assessment shall demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they shall assess with a subject matter expert who does meet these requirements.
  • Technical competence can be demonstrated through one or more of:
  • relevant VET or other qualification/Statement of Attainment
  • appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions
  • appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions
  • Currency can be demonstrated through one or more of:
  • being currently employed undertaking the type of work being assessed
  • being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures
