Elements and Performance Criteria

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.
WHS requirements
WHS requirements include:
relevant legislation
protective equipment
material safety management systems, including use of material safety data sheets (MSDS)
hazardous substances and dangerous goods code
local safe operation procedures
WHS provisions in relevant awards and agreements
Environmental requirements
Environmental requirements include:
relevant legislation, regulations and codes
correct handling and disposal of liquid and solid waste
elimination or minimisation of gas, fume, vapour and smoke emissions, including fugitive emissions
dust elimination, minimisation and control
minimisation of energy and water use
elimination or control of excessive noise
use and recycling of refrigerants
Single zone duct distribution system
A single zone duct distribution system is a basic central system which can supply a constant air volume or a variable air volume at low, medium or high pressure through a single duct
Appropriate personnel
Appropriate personnel may include:
supervisor
leading hand
foreman
manager
engineer
technician
trainer
mentor
team member
customer
client
Enterprise procedures
Enterprise procedures may include:
use of tools and equipment
operating instructions, including job sheets, plans, drawings and designs
reporting and communication
manufacturer specifications
site operational procedures
references to industry standards
Resources
Resources may include:
reference manuals
scientific calculator
3-D CAD software
computer workstation and software, either stand alone or networked
test apparatus
appropriate tools of trade, equipment and materials
standard duct sizes and gauges
Contingencies and unexpected situations
Contingencies and unexpected situations that arise during the course of the design process may include:
cost or time overruns
unavailability of required components
changes in customer requirements after design process has started
regulatory change
site or building features not on plans or drawings
other situations not included in customer brief or normal enterprise procedures

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.
Overview of assessment
A person who demonstrates competency in this unit must be able to design basic single zone duct distribution systems to meet customer requirements, including cost specifications, and WHS and other regulatory requirements.
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 risk control measures
design basic single zone duct distribution systems to customer performance and cost requirements
select and size appropriate components, including fans and duct work
communicate technical requirements to others, including preparation of required drawings, CAD files and reports.
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.
