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!

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

assess business and environmental risk and incorporate risk management strategies into design

develop plans for tailings management facility (TMF) that specify technical, budgetary, plant/equipment, human resource, legislative and safety requirements

determine and plan for conditions which will lead to out-of-specification operations

plan and develop enterprise procedures for the waste/tailings management plan.

Evidence must be provided that demonstrates knowledge of:

tailings/waste characteristics and their impact on design of facilities, including:

mineralogy: residual resource potential and plant nutrients

chemical reactivity: toxicity, leachate potential, acid producing potential, spontaneous combustion, cementation/hydration and weathering

physical characteristics: particle size distribution, particle density compressibility, shear strength, liquefaction potential, erodibility and dusting potential

placement characteristics: placed dry density, particle sorting, permeability, bearing capacity and initial placement density

handling characteristics: solids content of slurries, trafficability during placement, flocculation/settling time and abrasiveness

tailings disposal strategies/issues, including:

the location of discharge points

the rotation sequence for discharges

the duration of deposition in an area

the location of settling ponds and decant facilities

the location and timing of intermediate paddock bunding

the likely landform created by the deposition processes at stages throughout operations up to and including final landform

flowable volumes and potential flow paths

operational maintenance requirements (e.g. dust suppression, fauna exclusion and drainage)

principles of operation of waste treatment and management of different tailings and water types, volumes and consistency.

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, and include one or more of the following:

legislative requirements, including work health and safety (WHS)

industry codes of practice and guidelines

environmental regulations and guidelines

Australian and other standards

licence and certification requirements

NSW Dams Safety Act, 1978 and the New South Wales the Dams Safety Committee or similar bodies in other states/territories

All operations to which this unit applies are subject to stringent health, safety and environment (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 HSE requirements, the HSE requirements take precedence

Hazards

Hazards include one or more of the following:

overtopping of dam wall

breach/collapse of dam wall

construction hazards

operational hazards (e.g. drowning)

eco hazards (e.g. wildlife)

hazardous products and materials

slippery surfaces, spills or leaks

extreme weather

other hazards that might arise

Procedures

All operations must be performed in accordance with relevant procedures.

Procedures are written, verbal, visual, computer-based or in some other form, include one or more of the following:

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

Logs and reports

Logs and reports include one or more of the following:

paper or electronic-based logs and reports

verbal/radio reports

reporting items found which require action

Design criteria

Design criteria include providing sufficient capacity for the adequate functioning of the TMF and include the following:

minimising unplanned seepage of hazardous materials through the dam wall or through the foundation into the ground water

protection against dust emissions especially of toxic materials

provision for unplanned or uncontained floodwater in high rainfall areas

Work requirements will be identified from one or more of the following:

briefings

handovers

orders

compliance documentation
