Application
This unit specifies the skills and knowledge required to conduct security screening of items using x-ray equipment. X-ray equipment includes single or multi-view equipment which may have threat-image projection system capability that can differentiate between organic and inorganic material.
It includes:
setting up, testing and operating x-ray equipment and managing the position and flow of items through the screening point
interpreting x-ray images to clarify the meaning of colours, shapes and sizes and using image enhancement functions to detect the presence of prohibited items such as weapons, explosives or dangerous goods
maintaining situational awareness to monitor and maintain security and respond quickly to detect and report security risks.
It applies to people working independently or under limited supervision as members of a security team.
This unit may form part of the licensing requirements for people engaged in security operations in those states and territories where these are regulated activities.
