Which of the following is NOT a use of screening equipment in security?

The correct answer is that providing onsite medical assistance is not a use of screening equipment in security. Screening equipment is primarily designed to detect, identify, and assess potential threats or unauthorized items that individuals may carry when entering a secure area. Such devices include metal detectors, x-ray machines, and other surveillance technologies that enhance access control procedures by ensuring that individuals and their belongings do not pose a security risk.

While communication systems play a critical role in security operations—including enabling response forces to coordinate with each other or with control centers—these functions do not typically fall under the category of screening equipment. The primary focus of screening equipment is threat assessment and access control, whereas providing medical assistance involves separate protocols and equipment tailored to health and emergency response, not security screening. Therefore, the option that mentions providing onsite medical assistance does not align with the functions of screening equipment.
