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!

Must provide evidence that demonstrates sufficient knowledge to interact with relevant personnel and be able to determine process loss through mass or energy balancing including knowledge of:

process and changes which occur at each step in selected value chain

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.

Sustainability incorporates all of

survival of the ecology/physical environment (to manage the impact of the business to ensure the survival of the physical environment)

economic viability (efficiency, cost and waste reduction and competitiveness to support survival of the business)

social sustainability (to manage the impact of the business to ensure its continued survival within the community and the survival of the community).

Mass/energy balancing includes one or more of

mass balancing is an analysis technique which allows for the calculation of mass flows and consumption through a process and losses of mass from the system/product

energy balancing is an analysis technique which allows for the calculation of energy flows and consumption through a process and the losses of energy from the system/product

mass and energy balancing may be undertaken as separate activities or in some circumstances as a combined mass/energy balance.

Appropriate response when impact cannot be prevented includes one or more of

capture and storage (e.g. scrubbing) and similar ‘end of pipe’ solutions

dilution/dispersion and similar techniques which reduce concentration but not amount

other approaches which meet the sustainability requirements.
