Evidence Guide

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 operating in self-contained regenerative oxygen breathing apparatus implementation of requirements, procedures and techniques for safe, effective and efficient operating in self-contained regenerative oxygen breathing apparatus working with others while using self-contained regenerative oxygen breathing apparatus that meets all of the required outcomes consistent timely operating in self-contained regenerative oxygen breathing apparatus 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 worksites 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 while using self-contained regenerative oxygen breathing apparatus
Guidance information for assessment	Consult the SkillsDMC User Guide for further information on assessment including access and equity issues.

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. 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.
Relevant compliance documentation may include:	legislative, organisation and site requirements and procedures manufacturer's guidelines and specifications Australian standards code of practice Employment and workplace relations legislation Equal Employment Opportunity and Disability Discrimination legislation
Self-contained regenerative oxygen breathing apparatus may be defined as:	"an apparatus which is worn by the wearer which contains all the functions to allow breathing in a hostile atmosphere without any connection to normal atmospheric conditions, and where the exhaled atmosphere is cleansed of carbon dioxide and the remaining oxygen can be re-used"
Pre-operational equipment tests may include:	visual inspection exhalation and inhalation valve operation positive and negative pressure leak tests pre-flushing cylinder contents pressure relief valve dosage high pressure leaks lung demand valve opening pressure pressure gauge zero test
Irrespirable Atmosphere is considered an atmosphere which is unsafe for a person to breathe as a result of either oxygen depletion or the presence of:	toxic fumes gases contaminants smoke or suspended particles heated atmospheres
Hazards may include:	fire explosion failure to maintain a face seal exhaustion of oxygen supply malfunction of equipment disorientation in smoke/darkness or confinement structural hazards and/or hazardous materials entrapment
Communications may include:	distress signals portable radio communications equipment signal lines hand signals telephone mobile phone
