Unit of competency details

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently:

• design exhaust,ventilation and dust collection systems
• apply safe working practices and procedures
• communicate, consult, negotiate and review with client and stakeholders
• research and respond to issues
• measure and investigate sites
• investigate options
• model and calculate system performance
• innovate and create a range of solutions incorporating systems thinking, continuous improvement and constraint and contingency management
• obtain sign-off on design
• document, create computer-aided design (CAD) graphics, and specify and develop instructions.

Context of and specific resources for assessment

• This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is, the candidate is not in productive work, then a simulated working environment must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.
• Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
• Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment

• Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
• Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
• Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.
• Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
• Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
• Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Client 

Client may be:

• internal or external to the designer’s organisation

Parameters to the brief 

The design brief may include the design of new equipment or fault analysis, rectification or modification to an existing design. Parameters to the design brief may include:

• determination of the degree of innovation and creativity expected by the client
• design process limits and budgets
• product cost limits and budgets
• performance specifications
• equipment availability, capacities and restrictions
• specified administrative, communication and approval procedures
• other special features and limits in the design brief

OHS, regulatory, sustainability and environmental issues 

OHS, regulatory, sustainability and environmental issues  may include:

• OHS Acts and regulations
• relevant standards
• industry codes of practice
• risk assessments
• registration requirements
• safe work practices
• minimising ecological and environmental footprint of process, plant and product
• maximising economic benefit of process plant and product to the organisation and the community
• minimising the negative OHS impact on employees, community and customer
• state and territory regulatory requirements
