Evidence Required

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

Critical aspects for assessment and evidence include

the breaking and making of a flanged joint in accordance with the organisations flange management procedure

recognising own skill limits and when to refer to another person

Context of and specific resources for assessment

Assessment of this competency will occur over a range of situations which will include typical disruptions to normal smooth operation This will require access to a plant over a period of time or a suitable method of gathering evidence of operating ability Where safety lack of opportunity or significant cost is an issue an industrybased simulation may be employed to assist the process

Guidance information for assessment

Assessment processes and techniques must be appropriate to the language competency and safety requirements of the site and consistent with workplace systems or procedures

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. 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.

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.
