What is a guard likely searching for when using a metal detector on persons entering a building?

When a guard uses a metal detector on individuals entering a building, the primary objective is to identify weapons and other metallic objects that could pose a security risk. Metal detectors are specifically designed to detect metal items, which often include firearms, knives, and other dangerous implements that could threaten safety in public or secured spaces. They help in maintaining a safe environment by preventing potentially harmful items from being brought inside.

While valuables, personal items, food, beverages, and electronic devices could also be present on individuals, they are not the main focus of a security search with a metal detector. The priority is always to ensure the safety of all occupants and visitors in the building by mitigating threats posed by weapons or metal objects.
