Prohibited items are items that are not allowed in certain places, such as airports, schools, or public events. These items can include weapons, explosives, illegal drugs, and hazardous materials. The purpose of prohibiting these items is to ensure safety and security for everyone in the area. Different locations may have specific lists of prohibited items. For example, airports often ban sharp objects like knives and scissors, while schools may restrict items like alcohol and tobacco. It is important to check the rules of each location to avoid bringing prohibited items.
