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. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Required knowledge 

Specific knowledge is required to achieve the performance criteria of this unit, particularly for its application in the various circumstances in which this unit may be used. This includes knowledge of the following as required to conduct filtering processes:

• air systems
• contaminant identification
• emergency procedures
• environmental principles

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 

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

The evidence required to demonstrate competency in this unit must be relevant to worksite operations and satisfy all of the requirements of the performance criteria, required skills and knowledge and the range statement of this unit and include evidence of the following:

• knowledge of the requirements, procedures and instructions for conducting filtering processes
• implementation of requirements, procedures and techniques for the safe, effective and efficient completion of filtering processes
• working with others to undertake and complete the filtering processes in a way that meets all of the required outcomes
• consistent timely completion of filtering processes that safely, effectively and efficiently meets the required outcomes

Context of and specific resources for assessment 

• This unit must be assessed in the context of the work environment. Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills.
• Assessment of this competency requires typical resources normally used in a resources and infrastructure sector environment. Selection and use of resources for particular worksites may differ due to the site circumstances.
• The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job.
• Customisation of assessment and delivery environment to sensitively accommodate cultural diversity.
• Aboriginal people and other people from a non English speaking background may have second language issues.
• Where applicable, physical resources should include equipment modified for people with disabilities. Access must be provided to appropriate learning and/or assessment support when required.

Method of assessment 

This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods:

• written and/or oral assessment of the candidate's required knowledge
• observed, documented and/or first hand testimonial evidence of the candidate's:

• implementation of appropriate requirement, procedures and techniques for the safe, effective and efficient achievement of required outcomes
• consistent achievement of required outcomes

• first hand testimonial evidence of the candidate's:

• working with others to undertake and complete the filtering processes

Guidance information for assessment 

Consult the SkillsDMC User Guide for further information on assessment including access and equity issues.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
