Security barriers react to unauthorized access or intrusion attempts. They are designed to detect and respond to any suspicious activity, such as an individual trying to breach a secure area or a vehicle attempting to ram through a checkpoint. Security barriers can be triggered by various factors, including motion sensors, pressure sensors, or vehicle detection systems, and they are programmed to automatically deploy countermeasures to prevent unauthorized entry. **

No, the security gate at the airport does not only react to metal. It is designed to detect a wide range of materials, including liquids, gels, plastics, and other prohibited items. The gate uses advanced technology such as X-ray scanners and metal detectors to ensure the safety and security of passengers and prevent any potential threats from being brought onto the aircraft. Additionally, security personnel are trained to identify suspicious items and behaviors that may pose a risk, regardless of whether they contain metal. **

Safety shoes with metal components, such as steel toe caps, can trigger metal detectors when passing through security gates. This can cause the alarm to sound and may require further inspection by security personnel.

It's important for individuals to be aware of the type of safety shoes they are wearing when passing through security gates to prevent any unnecessary delays or inconvenience. **
