Security checks are procedures designed to ensure safety and protect people and property. These checks can happen in various places, such as airports, schools, and public events. They often involve screening bags, using metal detectors, and checking identification to prevent dangerous items or individuals from entering restricted areas. In airports, for example, security checks are crucial for passenger safety. Travelers must pass through security scanners and have their luggage inspected before boarding a flight. This process helps to identify any potential threats, ensuring that everyone can travel safely and enjoy their journey without worry.
