What is NABH Hospital Emergency Codes: Read Full List, Activation Workflow and Drill Checklist
NABH hospital emergency codes are colour-named alerts that tell staff which emergency is happening and where, such as Code Blue for cardiac arrest, Code Red for fire and Code Pink for child abduction.
Every NABH-accredited hospital in India runs some version of this system, and assessors expect staff at every level to know it. Yet the lists circulating online contradict each other. One says Code Red means fire, another says it means an external disaster. One uses Code Yellow for a chemical spill, another for mass casualties. For a quality manager preparing for an accreditation visit, that confusion is a real risk, because a code that half the floor interprets differently is worse than no code at all.
This guide gives you a reconciled list of the codes used in Indian hospitals, explains where they connect to the NABH 6th Edition standards, walks through how a code should move from bedside to responding team, and ends with a drill plan you can run before your next assessment.
What changed with the 6th Edition: The NABH Hospital Accreditation Standards 6th Edition took effect on 1 January 2025. NABH's own summary of changes flags added emphasis on training staff in emergency codes, a new objective element on responding to non-fire emergencies, and clearer expectations on how often resuscitation teams meet. If your code policy was written against the 5th Edition, it is worth reviewing now.
What are NABH hospital emergency codes?
An emergency code is a short, pre-agreed phrase that mobilises the right people without spreading panic among patients and visitors. A nurse who finds an unresponsive patient does not shout for help down the corridor. She dials the hospital's emergency extension, the operator announces "Code Blue, Ward 4B, second floor" three times, and a trained resuscitation team heads there while everyone else carries on.
NABH accreditation expects a hospital to have a documented emergency code system, a trained team for each code, and evidence that the system works. In practice, NABH does not hand hospitals a single mandatory colour chart. Each hospital defines its own list in its emergency management policy. NABH's E-Mitra toolkit does, however, supply mock drill reporting formats for three codes (Code Red for fire, Code Pink for infant or child abduction, and Code Blue for cardiac arrest), which is a strong signal of which meanings assessors treat as standard.
Full list of hospital emergency codes used in India
The table below reconciles the NABH hospital emergency codes that appear most often in hospital policies, training decks and staff handbooks. The "Also seen as" column is there on purpose. If your hospital uses one of the alternative meanings, that is not automatically wrong, but staff who transfer from another hospital will arrive with the other meaning in their heads, so induction training needs to say so out loud.
| Code | Most common meaning in Indian hospitals | Also seen as | Who typically responds |
|---|---|---|---|
| Code Blue | Adult cardiac or respiratory arrest; any patient needing immediate resuscitation | Rarely varies | Code Blue team: physician or anaesthetist, ICU nurse, airway support |
| Code Pink | Infant or child abduction | Missing patient (some older handbooks) | Security, nursing in-charge, all exit points |
| Code Red | Fire or smoke | External disaster (older lists) | Fire response team, engineering, floor wardens |
| Code Yellow | External disaster or mass casualty incident | Chemical or biological spillage | Emergency department, triage lead, administrator on duty |
| Code Brown | Internal disaster (utility or structural failure) | External disaster; hazardous spill | Engineering, administration, affected departments |
| Code Black | Bomb threat or suspicious object | Rarely varies | Security, administration, police liaison |
| Code Violet / Purple | Violent or aggressive person | Mob violence; fights and altercations | Security, duty manager |
| Code Grey | Security threat or combative person | Overlaps with Code Violet in many hospitals | Security |
| Code Orange | Hazardous material spill or exposure | Evacuation (a few hospitals) | Engineering, infection control, safety officer |
| Code Green | Evacuation of an area or building | Rarely varies | Floor wardens, nursing, security |
Two patterns are worth noticing. First, the three codes NABH provides drill formats for (Blue, Pink and Red) are the most stable across hospitals. Second, the violence and hazard codes (Violet, Purple, Grey, Orange, Brown) are where lists drift most. If you are writing or revising a policy, those are the rows to define most carefully.
Why do emergency code lists disagree between hospitals?
Colour codes grew up hospital by hospital. Indian policies borrowed from US state hospital associations, from Australian and Canadian standards, and from each other, each with slightly different meanings. Without a single national chart, a hospital that opened in 2005 and one that opened in 2020 can end up with different answers to the same question.
The fix is not to hunt for the "correct" list online. It is to make your own list unambiguous and to prove that every staff member knows it:
- One source of truth. A single emergency code policy, version-controlled, approved by the hospital's safety committee.
- Location in every announcement. Code, then building, floor and ward, repeated three times. "Code Blue" alone sends people in the wrong direction.
- Pocket cards and badge tags. Staff rotate across departments and shifts. A card behind the ID badge settles arguments in seconds.
- Induction that names the differences. Tell new joiners from other hospitals, explicitly, which of your codes differ from what they may have learned.
- A plain-language fallback. For drills, visitors and new contract staff, some hospitals pair the code with a short plain description ("Code Red, fire, Block C kitchen"). Decide in your policy whether you allow this, and apply it consistently.
How is an emergency code activated, step by step?
The mechanics differ by hospital size, but a well-run activation always follows the same shape. The diagram shows the chain from the moment someone recognises the emergency to the point where the event is closed and documented.
Steps 3 and 4 are where most delays happen. In a hospital that relies only on the overhead public address system, the announcement reaches whoever is within earshot. The anaesthetist in the cafeteria, the security supervisor on the ground-floor gate and the administrator on call at home may not hear it at all. That is why many hospitals add a second layer that calls or messages each named responder directly.
Overhead page, phone tree or automated alert: which reaches the team faster?
Most hospitals combine methods. The question for a quality team is which method carries the load, and whether it produces the evidence an assessor will ask for.
| Method | Reaches staff away from the floor | Audit trail for NABH evidence | Main weakness |
|---|---|---|---|
| Overhead PA only | No; only people within earshot | Manual log by the operator | Noisy areas, closed OTs and off-site on-call staff miss it |
| Operator phone tree | Yes, one call at a time | Manual log | Slows down as the team gets bigger; depends on one person under pressure |
| Pagers or group chat | Yes, if devices are carried and charged | Partial; read status is unreliable | Easy to miss, easy to mute, no guaranteed acknowledgement |
| Automated voice call plus SMS | Yes, all named responders at once | Automatic: who was alerted, when, who answered | Needs contact lists kept current as rosters change |
Automated alerting is what Elision's Code Blue emergency alert system was built for. When an operator triggers a code, it sends a voice call and an SMS to every member of the configured response group at the same time, with the emergency type and location. It retries numbers that do not answer and keeps a log of every alert. Each code can have its own contact group, so a Code Pink reaches security and exit-point staff, not the resuscitation team.
At CIMS Hospital, Code Blue was deployed alongside a multi-level IVR and a patient care solution. Elision's CIMS Hospital case study quotes the hospital's IT leadership describing the emergency alert system as exceptional in handling emergency cases, and Elision's CIMS page lists a +95.89% figure for emergency handling.
Where do emergency codes sit in the NABH 6th Edition standards?
The 6th Edition has 10 chapters, 100 standards and 639 objective elements. Emergency codes do not have a chapter of their own. Instead, they run through several chapters, which is why a code policy that satisfies one assessor's line of questioning can still leave gaps in another. The table maps the chapters that matter most.
| NABH chapter | How it relates to emergency codes | What to have ready for assessors |
|---|---|---|
| Care of Patients (COP) | Resuscitation readiness: equipment and medicines for basic and advanced life support where needed (COP.5), and regular resuscitation team meetings | Crash cart checklists, Code Blue team roster, minutes of team reviews, Code Blue event records |
| Facility Management and Safety (FMS) | Fire emergencies and, since the 6th Edition, an explicit objective element on non-fire emergencies (FMS.7) | Fire and disaster plans, Code Red drill records, plans for bomb threats, violence and utility failure |
| Human Resource Management (HRM) | Staff training content now explicitly emphasises emergency codes | Induction and refresher attendance, code awareness quiz results, training for contract staff |
| Patient Safety and Quality Improvement (PSQ) | Using data from incidents and drills to improve | Drill metrics, corrective and preventive actions, trend reviews |
Wording of the standards is paraphrased here. Always check the objective elements and interpretation text in the official NABH document linked in the sources section before you finalise a policy.
A 60-day emergency code readiness plan
If an assessment is on the calendar, this sequence covers the ground above without trying to do everything in one week. It assumes a mid-sized hospital with an existing but outdated code policy.
- Days 1 to 7: Audit what you have. Collect the current policy, every poster and pocket card on the floors, and the operator's announcement script. Ask ten staff from different departments what Code Yellow and Code Brown mean. The mismatch rate tells you where to focus.
- Days 8 to 14: Fix and approve the list. Settle every ambiguous code, add location rules to the announcement script, and take the revised policy through the safety committee.
- Days 15 to 21: Replace the physical materials. Reprint posters, badge cards and phone stickers with the emergency extension. Remove every old version; outdated cards are the most common source of drift.
- Days 22 to 30: Train. Run short sessions by shift, including housekeeping, security and contract staff. Record attendance for HRM evidence.
- Days 31 to 35: Configure alert groups. Map each code to a named response group with current mobile numbers. Assign one person to update the groups whenever duty rosters change.
- Days 36 to 55: Drill Red, Pink and Blue. Use NABH's E-Mitra mock drill formats so your records match what assessors expect. Run at least one drill on a night shift.
- Days 56 to 60: Review and correct. Compare drill timings, write corrective and preventive actions, and schedule the next round of drills.
Which drill metrics should the quality team track?
A drill report that says "drill conducted successfully" does not help anyone improve. Timings do. These are the intervals worth capturing for every drill and every real event.
| Metric | Measured from and to | What a poor result usually means |
|---|---|---|
| Time to activate | Recognition to emergency extension dialled | Staff unsure of the number or hesitant to call a code |
| Time to announce | Call received to first announcement | Operator verification steps are too slow or unclear |
| Responder acknowledgement | Share of the response group that confirmed the alert | Out-of-date contact lists or reliance on PA only |
| Time to team arrival | Announcement to first responder at location | Location not announced clearly, or team members off the floor |
| Documentation completeness | Fields completed on the drill or event form | Form too long, or no one owns the paperwork |
An automated alert log makes the middle three far easier to measure, because the system records when each person was called and whether they answered.

Frequently asked questions
Does NABH prescribe a fixed list of emergency codes?
No single colour chart is imposed on every hospital. NABH expects a documented code system, trained staff and evidence of drills. Its E-Mitra toolkit provides drill formats for Code Red (fire), Code Pink (child abduction) and Code Blue (cardiac arrest), so those three meanings are the safest to treat as standard.
What is Code Blue in a hospital?
Code Blue signals a cardiac or respiratory arrest, or any patient who needs immediate resuscitation. It calls the resuscitation team, usually a physician or anaesthetist, an ICU nurse and airway support, to the announced location.
Is Code Red fire or external disaster?
In most current Indian hospital policies, Code Red means fire. Some older lists use it for external disasters. Check your own policy, and if your hospital uses the older meaning, tell new staff explicitly during induction.
How should an emergency code be announced?
State the code name followed by the exact location (building, floor and ward) and repeat it three times. Announcing the code without a location wastes responders' time.
How often should hospitals run emergency code drills?
Your hospital's policy should set the frequency, and it should cover every shift, including nights. Check the current NABH interpretation text for your accreditation level, and keep records in a consistent format such as the E-Mitra mock drill reports.
Which NABH chapters do assessors check for emergency codes?
Mainly Care of Patients for resuscitation readiness, Facility Management and Safety for fire and non-fire emergencies, and Human Resource Management for staff training. Quality improvement evidence from drills supports all three.
Why is an overhead announcement not enough on its own?
It only reaches people within earshot. Responders in operating theatres, in other buildings or on call from home can miss it. A direct call and SMS to each named responder closes that gap and leaves a timestamped record.
Can one system handle different codes for different teams?
Yes. An automated alerting system such as Elision's Code Blue lets each code have its own response group, so Code Pink alerts security and exit staff while Code Blue alerts the resuscitation team.
