Foundation skills essential to performance are explicit in the performance criteria of this unit. Further information is available in the Resources and Infrastructure Industry Training Package Companion Volume.

Evidence is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:

• locates and applies relevant documentation, policies and procedures
• demonstrates completion of entering and working in confined spaces that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

• obtain appropriate entry permit and instructions for performing work in confined space
• interpreting and applying safe work method statements
• apply tagging and lock out
• selecting, wearing and caring for personal protective equipment applicable to all tasks and environment identified
• entering the confined space
• using atmospheric monitoring devices prior to entering the confined space
• working in the confined space
• using atmospheric monitoring devices during confined space activity
• applying safe materials handling methods
• exiting the confined space
• remove tagging and lock out

The candidate must demonstrate knowledge of enter and work in confined spaces through:

• identifying areas that constitute confined spaces
• complying with site and equipment safety requirements
• complying with the entry and exit procedures, risks and regulations
• types of air contaminants and toxic gases
• identifying the limitations of breathing apparatus
• identifying equipment types, characteristics, technical capabilities and limitations
• complying with site isolation and site control responsibilities and authorities
• locations of safety data sheets (SDS) information and application
• using confined space and Industry terminology

• An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,
• this unit is best assessed in the context of this sector’s 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 this sector’s workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills; and,
• this unit must be assessed in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,
• assessment may be conducted in conjunction with the assessment of other Units of Competency; and,
• assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,
• assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,
• where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,
• assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:

*Assessors can demonstrate current work experience through employment within Industry in a role relevant to the outcomes of the Unit; or, for external assessors this can be demonstrated through exposure to Industry by conducting frequent site assessments across various locations.

**Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level
