Description
Employability Skills
Learning Outcomes and Application This unit involves the skills and knowledge required to screen articles by interpreting 3D computed tomography (CT) X-ray images at a transport security protection workplace in compliance with relevant regulatory requirements and national operating standards.It includes setting up and testing 3D CT X-ray screening equipment; operating 3D CT X-ray screening equipment; interpreting 3D CT X-ray images; identifying weapons, explosives and prohibited items, and taking appropriate action when weapons, explosives and prohibited items are detected.This unit addresses transport security technical skill requirements (physical, mental and task-management abilities) related to transport security duties of aviation, maritime and air cargo security personnel, and contributes to safe and effective performance in operational transport security environments.Operations are conducted as part of transport security across a variety of operational aviation, maritime and air cargo contexts within the Australian industry.Work is performed independently or under limited supervision as a single operator or within a team environment.Licensing, legislative, regulatory or certification requirements are applicable to this unit.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Assessment must occur in workplace operational situations or simulated workplace operational situations that reflect workplace conditions.

Resources for assessment must include access to:

3D CT X-ray equipment or acceptable means of simulation assessment

a range of relevant exercises, case studies and/or simulations

applicable documentation, including workplace procedures, regulations, codes of practice and operation manuals

relevant materials, tools, equipment and personal protective equipment (PPE) currently used in industry.
