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.

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:

manufacturer's technical information

job cards

drawings

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:

heat, smoke, dust, vapours or other atmospheric hazards

weight, shape, volume of materials to be handled

slippery surfaces, spills or leaks

electricity

gas

gases and liquids under pressure

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.

Problems

Routine and non-routine problems must be resolved.

Routine problems are predictable and have known solutions and include one or more of:

compact product with tight bends/clearances

loss of fluids (concrete leakage)

variations in cement/water ratio

backing concrete that penetrates veneers

raw materials supply

product quality problems.

Non-routine problems are unexpected problems or variations of previous problems.

Non-routine problems must be resolved by applying operational knowledge to develop new solutions, either individually or in collaboration with relevant experts, to:

determine problems needing action

determine possible fault causes

develop solutions to problems which do not have a known solution

follow through items initiated until final resolution has occurred

report problems outside area of responsibility to designated person.

Operational knowledge includes one or more of:

procedures

training

technical information, such as journals and engineering specifications

remembered experience

relevant knowledge obtained from appropriate people.

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.
