Required Skills
Required skills |
Look for evidence that confirms skills in: applying relevant OHS procedures, including selection and use of MSDS and PPE fitment of applicable safety devices egress system disarming and rearming safely handling explosive components conducting tests involving continuity, gauging and measuring identifying and selecting applicable items of specialist equipment and tools using maintenance documentation, hand tools, specialist tools and equipment to perform egress system maintenance tasks preparing removed explosive components for safe storage or transportation |
Required knowledge |
Look for evidence that confirms knowledge of: egress system construction, layout and operation operation, characteristics and limitations of aircraft egress systems effect of environmental conditions colour coding, marking and labels associated with egress systems operation, characteristics and limitations of specialist tools and equipment egress system test procedures safety precautions associated with explosive components requirements for handling and disposal of explosive components general OHS procedures applicable to egress system maintenance, including applicable PPE how to obtain and use MSDS |
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 aircraft egress systems and system components while 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 egress system maintenance activities. It is essential that assessment confirms the ability to comply with organisational safety requirements and appropriate legislative and regulatory requirements while maintaining aircraft egress systems. The ability to work safely within an explosive ordnance environment, conduct applicable tests and maintain relevant documentation is critical. Evidence of transferability of skills and knowledge related to egress system maintenance is essential. This is to be established through demonstration of the ability to: render the system safe perform relevant inspections and tests, replace components (including disarming and re-arming the system) perform appropriate maintenance tasks. 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 range of tasks that is representative of the maintenance tasks, tests and the range of non-explosive and explosive components listed in the Range Statement. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide. |
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. Access will also be required to facilities and resources used in the storage, distribution or maintenance of explosive ordnance, including a licensed explosive site. |
