What does the code "code green" indicate?

The code "code green" is widely recognized in various organizations, particularly in healthcare settings, to indicate a situation involving a missing child. This designation is critical as it prompts immediate action and coordination among staff to locate the child quickly and safely. In environments like hospitals or schools, time is of the essence when a child goes missing, and using a specific code helps minimize confusion and ensures that personnel are aware of the emergency without causing widespread panic among patients or visitors.

The other choices pertain to different emergency situations: weather shelter generally refers to preparations for severe weather conditions, a fire would typically be indicated by a different code or signal, and housekeeping issues like vomit would not usually utilize a code designed for emergencies. Thus, "code green" specifically points to child safety protocols, underlining its crucial application in those scenarios.
