Chicago/Illinois Security Guard PERC Practice Exam

The correct answer is 10-52, which is the 10 code for requesting an ambulance. 10 codes are radio shorthand used by law enforcement, emergency services, and other communicating agencies to transmit information quickly and efficiently. The purpose of these codes is to standardize communications and eliminate any misunderstandings or misinterpretations that might occur. They were first developed in the United States but are now used in various forms around the world. In this coding system, 10-52 specifically refers to the need for an ambulance. This means that if a security guard radios in a "10-52," they are indicating a medical emergency and requesting an ambulance to be sent to their location. This same code is used by police and other emergency responders, allowing for clear, unambiguous communication among all parties.
