Florida Correctional Officer Safety Practice Test

The primary function of a metal detector in security procedures is to detect metal. Metal detectors are specifically designed to identify objects made of metal, which is essential in security settings, such as correctional facilities, airports, and other high-security areas. The ability to detect various types of metal, including weapons like guns and knives, is crucial for maintaining safety and security. While metal detectors can be integral in contraband detection, they primarily function by emitting an electromagnetic field that detects the presence of metal objects within range. This ability to pinpoint metal is what allows security personnel to address potential threats effectively. Other options listed, such as monitoring body temperature or detecting explosives, are not within the primary capabilities of a standard metal detector, as those functions typically require specialized equipment or procedures.
