Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

applying relevant WHS procedures, including selection and use of PPE

using MSDS

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.

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.

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.
