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	A person who demonstrates competency in this unit must be able to maintain and fit immersion suits while using the correct PPE and observing all relevant safety precautions
Critical aspects for assessment and evidence required to demonstrate competency in this unit	The underlying skills inherent in this unit should be transferable across a range of aircraft life support equipment maintenance activities It is essential that immersion suit testing and inspection procedures cleanliness requirements and safety precautions including the correct use of PPE are fully observed understood and complied with Ability to interpret maintenance and fitting procedures and apply them in practice is critical Evidence of transferability of skills and knowledge related to immersion suit maintenance and fitting is essential This is to be demonstrated through demonstration of the ability to recognise faults and damage and perform appropriate repairs that are within the bounds of the individuals authority and through the demonstration of correct fitting procedures The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the Unit of Competency are being achieved under routine supervision on a representative range of maintenance tasks and on the correct fitting of immersion suits This shall be established via the records in the Log of Industrial Experience and Achievement or where appropriate an equivalent Industry
Context of and specific resources for assessment	Competency should be assessed in the workplace or simulated workplace using materials tools and equipment specified in the maintenance manuals and applicable procedures It is also expected that general and special purpose tools and ground support equipment would be used where appropriate
