Elements and Performance Criteria

  1. Identify the requirements for hand mixing of materials
  2. Pre-plan hand mixing operations
  3. Check hand mixing set-up
  4. Conduct hand mixing operations
  5. Respond to product quality improvement requests
  6. Respond to routine problems to procedures

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 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.


Performance Evidence

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

take action to resolve faults or report problems to appropriate personnel

distinguish between possible causes of routine problems, including:

wrong raw materials/additives/catalyst

incorrect quantity of materials/additives/catalyst

contaminated materials/additives/catalyst

inadequate mixing

incorrect setting times/temperature/composition

atmospheric conditions

process/procedural problems

communicate effectively with team/work group and supervisors

complete workplace records

use measuring systems, scales and calculating devices

do basic arithmetical manipulations, including additions, subtractions, divisions, fractions and percentages.


Knowledge Evidence

Must provide evidence that demonstrates knowledge relevant to their job sufficient to operate under routine only supervision and to solve routine problems, including knowledge of:

types and applications of materials commonly mixed by hand

characteristics of commonly blended materials and the impact on production process and final product quality

common mixing methods and related tools/equipment

sources of contamination that may affect the mixture and how to eliminate them

routine and non-routine problems that may arise, the range of possible causes and appropriate actions

impact of incorrect or faulty materials on mixture

organisation procedures relevant to the work environment/job role

hierarchy of control

hazards that may arise in the job/work environment and:

their possible causes

potential consequences

appropriate risk controls.
