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 | Evidence of the following is essential: conducts detailed exterior and interior inspections of SCUBA cylinders to determine condition and detect any damage fills SCUBA cylinders to correct capacity according to Australian Standards, industry technical and safety criteria, relevant legislation and organisational policies and procedures documents details of air purity and leakage tests, inspections and cylinder filling, including details of compliance or non compliance. |
Context of and specific resources for assessment | Assessment must ensure inspecting and filling SCUBA cylinders on sufficient occasions to demonstrate competency and consistency of performance. Assessment must also ensure access to: a variety of SCUBA cylinders in various conditions SCUBA cylinder inspection equipment such as vice or clamp and spanners resources and equipment to conduct inspections and fill SCUBA cylinders maintenance history of SCUBA tank. |
Method of assessment | A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: oral or written questioning to assess knowledge of exterior and interior inspection techniques and procedures used to fill SCUBA cylinders observation of safe operation, maintenance and handling of high pressure gas compressors and SCUBA cylinders documentation, records and reports outlining details of inspection and filling of SCUBA tank third-party reports from a supervisor detailing performance. Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended. |
