Hospital Red Alerts: What They Mean And Why They Matter

what is a red alert in hospital

Hospitals use colour codes to indicate different emergency situations. These codes are often not standardised across hospitals, which can lead to confusion and delayed response times. In recent years, there has been a push for plain language alerts and colour code standardization in hospitals. A Red Alert is a type of emergency code used in hospitals to indicate that a fire has been spotted. When a Red Alert is called, it is followed by the location of the fire, and those in the area are expected to follow the fire procedures for that area.

Red alert meaning: fire spotted, prepare to evacuate

A Red Alert in a hospital means that a fire has been spotted and staff and visitors should prepare to evacuate. The alert is followed by an announcement of the fire's location, and those in the area should follow the fire safety procedures for their specific area.

Standardization of Color Codes

The use of color codes in hospitals is not standardized across the United States. However, there is a growing realization of the importance of standardization, and at least 25 state hospital associations have recommended plain language alerts.

Examples of Color Codes

While color codes vary among hospitals, here are some examples of commonly used codes:

  • Code Green: Activating an emergency operations plan, often due to the arrival of patients from a mass casualty event or a missing high-risk patient.
  • Code Silver: Indicating a person with a weapon, an active shooter, or a hostage situation.
  • Code Black: Signifying a bomb threat, which requires the implementation of an evacuation protocol.
  • Code Pink: Indicating infant abduction or cardiorespiratory arrest.
  • Code Purple: Referring to a missing child between the ages of 1 and 12.
  • Code Walker Adolescent: Used for a missing teenager between the ages of 13 and 17.
  • Code Walker Adult: Signifying a missing adult who is 18 or older.

Improving Emergency Response

The standardization of color codes and the adoption of plain language alerts aim to improve emergency response times and ensure that staff, professionals, and visitors can clearly understand and act upon emergency notifications.

Code standardisation: plain language vs colour codes

Hospital emergency codes are coded messages announced over a public address system to alert staff to various classes of on-site emergencies. The use of codes aims to convey essential information quickly and with minimal misunderstanding to staff while preventing stress and panic among visitors to the hospital.

Colour Codes

Colour codes are used in hospitals to indicate various emergency situations. For example, "Code Red" indicates that a fire has broken out, and is followed by the location of the fire so that those in the area can follow the necessary procedures. "Code Black" indicates a bomb threat, while "Code Blue" indicates that a patient has entered cardiac arrest. However, the meaning of colour codes can vary between hospitals, even within the same community, leading to confusion and potential safety risks. For instance, "Code Pink" can mean either infant abduction or infant cardiorespiratory arrest, and "Code Green" can indicate either the activation of an emergency operations plan or the arrival of patients from a mass casualty event.

Plain Language Alerts

Plain language alerts aim to address the confusion caused by colour codes by using clear and descriptive language to convey emergency information. Instead of "Code Red", for example, a plain language alert will specify the type of alert, the event, the location, and any necessary instructions. An example of a plain language alert is: "Facility alert, fire alarm, 2nd Floor East, follow the evacuation plan". Plain language alerts are categorized into "Facility", "Medical", and "Security" alerts. They are designed to improve clarity and reduce confusion, minimize noise, and promote the use of alternative communication methods such as call notifications and mass texting.

Standardization

There is a growing movement towards standardizing emergency codes in hospitals to improve clarity and emergency response times. As of 2025, at least 25 states in the US recommended plain language alerts, and several hospitals have already adopted this system. However, some states continue to recommend color code standardization. The UK has standardized codes across individual NHS trusts and health boards, but there is a lack of standardization across the entire NHS to allow for differences in demands and roles of hospitals.

Code Pink: infant abduction or cardiorespiratory arrest

Hospital emergency codes vary widely by location, even between hospitals in the same community. This potential for confusion has led many states to adopt standardized codes for all hospitals. For example, in 2008, Oregon and Washington formed a task force to standardize emergency code calls. As of 2020, at least 25 state hospital associations had recommended plain language alerts.

Code Pink is a legacy colour code that typically means infant abduction but can also mean infant cardiorespiratory arrest. Infant abduction is a small subset of a much larger problem, but it is of particular concern to pediatric hospitalists because about half of these events occur within the hospital setting. Preventing infant abduction and maintaining preparedness for Code Pink situations is an ongoing challenge for hospitals.

In the case of infant abduction, a lockdown is usually initiated, and everyone available is expected to search for the infant. On the other hand, in the case of infant cardiorespiratory arrest, the code team is notified, and they are expected to respond appropriately. Failure to respond appropriately in either case could be disastrous.

Code Purple is similar to Code Pink, denoting a missing child or child abduction. In most cases, the hospital will go on lockdown during the search for the child to ensure no one leaves the building with them.

Code Silver: active shooter or hostage situation

Hospitals use a standardized system of colour codes to inform staff of emergency situations and to activate the appropriate emergency preparedness protocols. A Red Alert, for example, means that a fire has been spotted.

Code Silver is a hospital emergency code that alerts hospital staff to a person with a weapon, an active shooter, or a hostage situation. The Ontario Hospital Association recommended the addition of Code Silver in 2016 to standardize the language, application, and approach to managing a person with a weapon or an active shooter. Previously, active shooter and hostage situations were both classified under Code Purple (hostage situation). However, due to the significantly different responses required from hospital staff and the police in these two scenarios, it was deemed necessary to divide them into two distinct codes.

In an active shooter situation, the immediate actions of frontline personnel can directly impact the survival of patients and staff. Healthcare providers must balance their duty of care to patients with their own health and safety. The ethical and legal ambiguity of Code Silver makes it challenging for healthcare providers to know what is expected of them, potentially compromising their ability to respond decisively to protect themselves, their colleagues, and their patients.

To address this challenge, hospitals can implement the Code Silver Exercise (CSE), a low-cost simulation designed to prepare hospitals for an active shooter event. The CSE provides a reproducible training model that can be administered in multiple settings, including in-person (in situ or off-site) and virtual environments. This versatility allows participants to mentally rehearse practical responses to an active shooter within their unique work environments. Furthermore, the CSE facilitates discussions on the ethical and medical-legal implications of responses during a facilitated debrief with fellow healthcare providers. By participating in the CSE, hospital staff can improve their understanding of Code Silver protocols and enhance their ability to respond decisively during an actual active shooter or hostage situation.

Code Black: bomb threat, evacuate the hospital

Code Black indicates a bomb threat. Hospitals should have an evacuation protocol in place in the event of a bomb threat. The protocol for responding to a bomb threat may vary depending on the hospital's specific policies and procedures, but the following general steps should be taken:

  • Notify hospital security, law enforcement, or the appropriate authorities about the threat.
  • Evacuate the immediate area around the threat and direct people away from the area.
  • Close off access to the area and restrict entry to authorized personnel only.
  • Follow established hospital protocols for handling bomb threats, including procedures for identifying and containing potential explosive devices.
  • Provide clear communication to hospital staff regarding the situation and any necessary actions.
  • Record all actions taken, including communications with authorities, evacuation procedures, and any other relevant information.

It is important to take bomb threats seriously and handle them with caution to ensure the safety of patients, visitors, and hospital staff. Evacuating patients from a hospital requires careful planning and execution to ensure their safety. The emergency plan should include specific procedures for evacuating patients, such as designated evacuation routes and assembly points. Roles and responsibilities should be clearly assigned to staff members involved in the evacuation process.

Frequently asked questions

A red alert means that a fire has been spotted. It is followed by the location of the fire, and those in that area should follow the procedures for their area.

Colour codes help standardise emergency responses across hospitals. They allow for faster response times and ensure that people know how to react in emergency situations.

Other colour codes include yellow, orange, pink, purple, black, silver, and green. For example, Code Pink typically means infant abduction, but can also mean infant cardiorespiratory arrest.

No, but at least 25 states recommend colour code standardization as of 2020, and this number is growing. Some states that recommend standardization include Arizona, Colorado, Florida, Hawaii, Kansas, and Louisiana.

Code Green indicates that the hospital is activating an emergency operations plan. It is often used to alert the arrival of patients from a mass casualty event or to denote a missing high-risk patient.
