Training critical judgement on x-rayed job-relevant items:
OTS primary staff control – X-ray interpretation training for basic training


Are airport employee allowed to take a 2 liter bottle of water with them?
Can a janitor pass X-ray screening when carrying a wrench?
Is a hammer permitted when taken with by a power station employee?
Which items pass access control in the security area – and which are prohibited?

Besides the theoretical general conditions of their area of operation, screeners have to thoroughly familiarize themselves with their practical duties and train their ability to recognize dangerous situations quickly and correctly. Hence, OTS primary staff control allows aspiring screeners to discover objects that are subject to staff screening and learn how to detect them. This basic training module on X-ray image interpretation is designed specifically for personnel who screens persons other than airline passengers at access control checkpoints such as airports, power plants, courts, or industrial companies. Tailored to the steadily increasing requirements in civil aviation, the simulator combines different categories and learning procedures to familiarize trainees with both daily and threat items, thus improving detection performance.

Regular and genuine training improves screeners’ ability to correctly assess threats – quick and reliable detection of dangerous objects is enormously important in highly-sensitive areas such as aviation.

Only frequent training allows security personnel to contribute to increasing global security.

OTS primary staff control is based on the STEP methodology, a pedagogical guideline that says from easy to difficult – from uncomplicated to challenging. Images are structured in four units: information, recognition, marking, and alarm. Hence, beginners first learn what everyday objects such as toothbrushes or smartphones look like in an X-ray image. For each item there is a description and definition as to which group of objects it belongs (e.g., weapons), which material it consists of (e.g., metallic), and which actions are to be taken if such an object appears at the screening point (e.g., inform police).

Moreover, students are taught to recognize items in Xray images and mark relevant items such as electronic devices. STEP guarantees for lasting learning success as it combines teaching and testing in a unique manner.

The OTS primary staff control simulator focuses on four key subjects, namely objects that require special permission, electronic devices, IEDs, and weapons. As most security-relevant objects are of organic material and fairly small, they are quite hard to detect. Moreover, screeners have to decide whether the displayed images contain forbidden objects or objects that require special permission.

OTS primary staff control perfectly complements the other products of the OTS family which enable employee training in basic and advanced courses. As with all of STI’s other OTS computer-based training courses, all images are recorded in .hif file format of the manufacturer Smiths Detection – lossless, high-quality original image files provide optimal conditions for learning and practicing. Of course all relevant image enhancement features of the X-ray machine are provided: Students can view the bag using image enhancement features such as ‘NEG‘, ‘SEN‘ or ‘OS‘. The simulated keyboard, an accurate copy from Smiths Detection Xray machines, facilitates authentic, practical training.

OTS primary staff control hence enables screeners to identify everyday objects in baggage carried by other persons than airline passengers, detect threat items, and distinguish between permitted and prohibited items.

Our software solutions are offered in packages which not only include theoretical and practical teaching, but also extensive evaluation, and are rounded off by online and offline support, as well as updates.
