Which items are typically included in "screening equipment" used in airport security?

Screening equipment used in airport security primarily consists of technologies designed to detect prohibited items, such as weapons and explosives, in baggage and on passengers. X-ray machines are utilized to scan carry-on luggage and checked baggage, providing visual images of the contents for security personnel to evaluate. Metal detectors are employed to screen individuals as they pass through security checkpoints, detecting metallic objects that could pose a threat.

The other options include items that, while important in the broader context of airport security and function, do not fall under the category of screening equipment. Body cameras and personal alarms relate more to law enforcement and safety protocols rather than direct screening of individuals or baggage. Fire detection systems and communication devices serve critical roles in airport safety and operations, yet they do not specifically aid in the screening process of detecting prohibited items. Similarly, passenger baggage carts and conveyor belts facilitate the movement of luggage but do not actively screen or check for security threats.
