Which emergency code signals a hospital lockdown?

The emergency code that signifies a hospital lockdown is Code Yellow. This code is used to communicate that there is an internal emergency that necessitates the hospital restricting access to certain areas or the entire facility. During a Code Yellow, staff are typically instructed to ensure the safety of patients and secure entrances to prevent unauthorized personnel from entering, which is crucial in situations where there may be a threat to safety, such as an active shooter or a violent person within the premises.

In contrast, other codes serve different purposes within a hospital's emergency response plan. For example, Code White often refers to a pediatric medical emergency, while Code Pink is specifically related to infant abduction. Code Gray is typically used for a violent person, which does not imply a lockdown but rather addresses the immediate threat posed by an individual. Understanding the distinctions among these codes is vital for effective communication and response during emergencies in a healthcare environment.
