What is indicated by Code Black in a hospital emergency plan?

Code Black in a hospital emergency plan specifically indicates a bomb threat. This designation is used to alert staff, security, and emergency responders to the unique protocols that must be followed in the event of such a threat, ensuring that everyone is prepared to act in a safe and coordinated manner. Hospitals must have clear codes to communicate different types of emergencies quickly and effectively, and recognizing that a bomb threat carries distinct procedures is crucial for the safety of patients and staff. In contrast, other codes refer to different emergencies and would not apply in this context.
