Code Red is the universal hospital emergency code for a fire. When staff hear “Code Red” over the intercom, it means a fire or smoke has been detected somewhere in the facility, and every person in the building has a specific role to play in response.
What Triggers a Code Red
A Code Red can be activated by a fire alarm pull station, an automatic smoke detector, or a staff member who spots flames or smoke. It doesn’t have to be a large, visible fire. Smoldering equipment, an electrical short behind a wall, or smoke from a malfunctioning device can all trigger the alert. Once activated, the code sets off a chain of automatic building responses and coordinated human actions designed to protect patients who often cannot move themselves to safety.
The RACE Response Protocol
Hospital staff are trained to follow a four-step sequence called RACE whenever a Code Red is called. The steps happen quickly and sometimes simultaneously, depending on how close staff are to the fire.
- Rescue: Get anyone in immediate danger away from the fire or smoke. For hospitals, this often means moving patients who are bedridden, sedated, or connected to equipment.
- Alarm: Shout “fire” to alert nearby people and pull the nearest fire alarm station if it hasn’t already been activated. This ensures the entire building is notified.
- Confine: Close all doors when leaving an area. This is one of the most important steps, because closed doors dramatically slow the spread of fire and smoke through a building.
- Extinguish or Evacuate: Only trained staff attempt to put out small fires using an extinguisher. If the fire is beyond that point, the priority shifts to evacuation.
The order matters. Protecting people comes first, sounding the alarm comes second, and fighting the fire comes last, only if it’s small and safe to do so.
What Happens Inside the Building Automatically
Hospitals are designed so that a fire alarm triggers several building systems at once, without anyone pressing a button. Fire doors throughout the facility, which are normally held open by magnetic devices for convenience, release automatically and swing shut. This creates compartments that contain smoke and fire to a smaller area. HVAC systems may also adjust to prevent smoke from being circulated through the ventilation.
This built-in compartmentalization is a major reason hospitals handle fires differently than, say, an office building. Instead of everyone rushing for the exits, the first goal is to keep the fire contained to one zone while staff manage a controlled response.
How Hospital Evacuation Actually Works
If you’re imagining a hospital fire evacuation like a school fire drill where everyone files out to the parking lot, the reality is quite different. Most patients can’t simply walk outside. Many are on ventilators, IV drips, or recovering from surgery. That makes full building evacuation a last resort.
Instead, hospitals use a tiered approach. The first option is horizontal relocation: moving patients on the same floor to a safe area on the other side of a fire barrier. This is faster and far less risky than moving patients between floors. Vertical relocation, moving patients to a different floor, happens only if the fire compromises the entire floor. Full evacuation, transferring patients out of the hospital to other facilities, is reserved for worst-case scenarios where the building itself is no longer safe.
Fire Drills and Staff Training
Hospitals don’t just train staff once and hope for the best. The Joint Commission, the organization that accredits most U.S. hospitals, requires unannounced fire drills at unexpected times and under varying conditions. Each shift (day, evening, and night) must complete at least one drill per quarter. These drills are intentionally unpredictable so staff across all hours are prepared, not just the Monday morning crew.
Staff who may need to use a fire extinguisher are trained on the PASS method: pull the safety pin, aim at the base of the fire, squeeze the handle, and sweep side to side. But the emphasis in training is always on the bigger picture. Getting patients to safety and closing doors to contain the fire saves far more lives than attempting to fight it.
Why Some Hospitals Are Moving Away From Color Codes
One important thing to know: not every hospital uses color codes the same way. While Code Red almost universally means fire, other color codes (Code Blue, Code Pink, Code Gray) have historically varied between health systems. A color that means one thing at one hospital could mean something different across town.
Because of this confusion, there has been a push toward plain-language emergency alerts. Instead of announcing “Code Silver,” for example, a hospital might announce “active threat” so that visitors, new staff, and traveling nurses immediately understand the situation. The Joint Commission has supported this shift, and feedback from hospital workers indicated that ambiguous color codes added stress during emergencies rather than reducing it. That said, Code Red for fire remains one of the most consistently understood codes across the country, and many hospitals continue to use it alongside plain-language descriptions.
