Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

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.

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:

job card

emergency procedures

work instructions

safe work method statements (SWMS)

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant.

Problems

Routine problems must be resolved by applying known solutions.

Routine problems are predictable and include one or more of:

equipment malfunction

incorrect/variations in raw material

mixing tolerance

inconsistent dispersion of minor ingredients/additives

mixing to colour/other special requirements

mixed batch does not match requirements.

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.

Hazards

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

heat, smoke, dust, vapours or other atmospheric hazards

weight, shape, volume of materials to be handled

hazardous products and materials

sharp edges, protrusions or obstructions

slippery surfaces, spills or leaks

electricity

gas

gases and liquids under pressure

noise

rotational equipment or vibration

plant services (steam, condensate, cooling water, etc)

structural hazards

equipment failures

machinery, equipment and product mass

limited head spaces or overhangs

working at heights

working in restricted or confined spaces

other hazards that might arise.

Records and reports

Records include one or more of:

log books/sheets

electronic records

job/work sheets

other records used for the smooth running of the plant.

Reports include one or more of:

paper or electronic-based logs and reports

verbal/radio reports

reporting items found which require action.
