MEM23149A Contribute to the design of commercial and industrial exhaust systems

Modification History

Release 1 (MEM05v9).

Unit Descriptor

This unit of competency covers the skills and knowledge required to contribute to the design of commercial and industrial exhaust systems, including industrial dust extraction systems or for less complex systems to undertake the complete design.

Application of the Unit

The unit applies to technicians in enterprises that design whole commercial and industrial exhaust systems or undertake design modifications to existing systems as part of manufacturing, installation, commissioning, servicing and maintenance activities.

The unit applies to design work undertaken as part of a design team comprising engineers and other technicians and to individual design tasks within the technician’s skill and knowledge.

Evidence Guide

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: implement WHS workplace procedures and practices, including the use of risk control measures as specified in the performance criteria and range demonstrate essential knowledge and skills to design commercial and industrial exhaust systems demonstrate competence within a timeframe typically expected of the discipline, work function and industrial environment demonstrate the ability prepare the design, drawings and specifications of a variety of exhaust systems. This must be demonstrated consistently on two (2) different systems demonstrate the ability to design commercial and industrial exhaust systems consistent with codes and regulations. This must be demonstrated consistently on different systems.
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, then an appropriate simulation 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. The assessment environment should not disadvantage the candidate.
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 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 not only able 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.

Range Statement

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.
