apply legislative, organisation and site requirements and procedures

apply operational, maintenance and basic diagnostic procedures

apply materials handling methods

use atmospheric monitoring devices

interpret JSAs/Safe work method statements

Required knowledge

Specific knowledge is required to achieve the performance criteria of this unit, particularly its application in a variety of circumstances in which the unit may be used. This includes knowledge of the following as required to enter and work in confined spaces:

site and equipment safety requirements

confined space entry and exit procedures, risks and regulations

air contaminants and toxic gases

breathing apparatus limitations

equipment types, characteristics, technical capabilities and limitations

site isolation and site control responsibilities and authorities

state and territory interpretations of a confined space

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.

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 entering and working in confined spaces

implementation of requirements, procedures and techniques for the safe, effective and efficient completion for entering and working in confined spaces

working with others to undertake and complete the entering and working in confined spaces that meet all of the required outcomes

consistent timely completion of entering and working in confined spaces 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.

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.

Assessment of this competency requires typical resources normally used in the work environment. Selection and use of resources for particular work sites may differ due to site circumstances.

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

consistently achieving the required outcomes

first hand testimonial evidence of the candidate's:

working with others to undertake and complete the entering and working in confined spaces

Guidance information for assessment

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