Full origin of code red →Frequently asked questions
What does code red mean in a hospital?
In most hospital systems code red announces a fire or suspected fire, triggering evacuation and containment procedures. Codes are not fully standardised, so the exact meaning can differ between hospitals and countries — code blue for cardiac arrest is the most consistent across systems.
What is the difference between code red and code blue?
Code blue is a medical emergency for a specific patient, usually cardiac or respiratory arrest, and summons the resuscitation team. Code red is an environmental emergency affecting the building, most often fire. One is about a person, the other about the place.
Is code red used outside hospitals?
Widely. Weather services, air-quality agencies, militaries and companies all use it for their most severe alert level, and it has passed into ordinary speech for any all-out crisis.
