Emergency response, decoded

Code Alerts.

Every hospital emergency colour code, what it means, and exactly who's expected to show up — plus RACE and PASS for fire, and HAZMAT/MSDS for chemical spills. NABH doesn't fix these exact colours in the book — FMS.3 and PSQ.3 require every organisation to define, train on, and drill its own emergency codes — but this is the convention most Indian hospitals have converged on.

Code Blue

Cardiac or respiratory arrest — any patient, visitor or staff member

Called the instant someone stops breathing or their heart stops — anywhere on the premises, not only in a clinical ward. The nearest staff member starts CPR immediately and calls the code; a dedicated resuscitation team responds with a crash cart within minutes.

Responding departments:

Duty physician / intensivistAnaesthesiologyNursing (unit + code team)Crash-cart / ICU nurseBiomedical (defibrillator backup)Security (crowd control)

NABH tracks this as a live indicator — "Code Blue Drill" is cited in the book's own Key Performance Indicators section (PSQ 3d) as an example of the mock-drill variations every organisation should measure and record.

Code Red

Fire — RACE for response, PASS for the extinguisher

R.A.C.E. — what every staff member does the moment fire or smoke is seen:

R
Rescue
Move anyone in immediate danger away from the fire first.
A
Alarm
Activate the fire alarm and notify the fire/security team.
C
Confine
Close doors and windows to contain smoke and flame.
E
Extinguish / Evacuate
Fight a small, contained fire — or evacuate if it's beyond that.

P.A.S.S. — how to use a fire extinguisher, if the fire is small enough to fight:

P
Pull
Pull the safety pin from the handle.
A
Aim
Aim the nozzle at the base of the fire, not the flames.
S
Squeeze
Squeeze the handle to release the agent.
S
Sweep
Sweep side to side across the base until it's out.

Responding departments:

Code Orange

Hazardous material spill — minor and major, plus HAZMAT & MSDS

NABH's FMS chapter requires the organisation to safely manage hazardous materials — including a documented spill-management plan that's actually implemented, not just written (FMS.5 area, asterisked elements). Code Orange is how most hospitals name that response.

Minor spill — small volume, low-hazard, staff-manageable with a spill kit and PPE, no evacuation needed (e.g. a broken mercury thermometer, a small reagent splash). The department's own trained staff contains and cleans it up using the on-site spill kit.

Major spill — large volume, or a toxic / flammable / corrosive substance, that threatens people beyond the immediate spot. The area is evacuated and cordoned off, and a trained HAZMAT response team (sometimes with the external fire department) manages containment and clean-up.

Chemicals that most often trigger Code Orange in a hospital:

Formalin / formaldehyde (histopathology, mortuary)Glutaraldehyde (endoscope disinfection) Xylene (histology lab)Mercury (broken thermometers, sphygmomanometers) Cytotoxic / chemotherapy drugsConcentrated acids & alkalis (lab reagents) Radioactive contrast material (nuclear medicine)

Responding departments:

Laboratory / HistopathologyCSSDHousekeepingFacility Management & EngineeringNursing (affected unit)Security (cordon the area)Quality Department (post-incident review)

HAZMAT management, in practice, means: chemicals labelled with hazard pictograms, incompatible chemicals stored apart from each other, PPE and spill kits stationed right where the chemical is used (not locked away elsewhere), a trained response team, and disposal that follows biomedical/hazardous-waste rules — not the regular bin.

MSDS (Material Safety Data Sheet) — NABH's own glossary defines it as a formal document describing a substance's hazards, including first-aid, spill, and safe-storage instructions. The internationally standard MSDS/SDS format has 16 sections:

01Identification
02Hazard(s) identification
03Composition / ingredients
04First-aid measures
05Fire-fighting measures
06Accidental release measures
07Handling & storage
08Exposure controls / PPE
09Physical & chemical properties
10Stability & reactivity
11Toxicological information
12Ecological information
13Disposal considerations
14Transport information
15Regulatory information
16Other information

Code Pink

Infant or child abduction / missing patient

Called the moment an infant, child, or at-risk patient goes missing. All exits are monitored or locked down, and everyone on shift is briefed on a description within minutes — the first few minutes matter most.

Security (lockdown & exit monitoring)Nursing (maternity / paediatrics)Administration on-callFront-desk / registration

Code Violet

Combative or aggressive person, workplace violence

Called when a patient, visitor, or staff member becomes verbally or physically aggressive and de-escalation isn't working. A trained response team moves in to protect staff and other patients while calming the situation — matching NABH's requirement (HRM.9) that the organisation has real measures in place for preventing and handling workplace violence.

SecurityNursing supervisor / shift in-chargeAdministration on-callPsychiatry / crisis liaison (if available)

Code Black

Bomb threat or suspicious object

Triggered by a bomb threat call or an unattended, suspicious item. Staff avoid touching the object, evacuate the immediate area, and hand off to security and, where warranted, the police bomb squad.

SecurityAdministrationFacility ManagementLocal police liaison

Code Yellow

Internal emergency / disaster (mass casualty influx)

Called when the hospital needs to activate its internal disaster plan — a sudden surge of patients that exceeds normal capacity. Elective work pauses, extra staff are called in, and triage areas expand.

Emergency DepartmentAdministration / Incident CommanderNursing (all units)Bed management

Code Brown

External disaster (mass casualty from outside the hospital)

Called for a large-scale external event — an accident, natural disaster, or mass-casualty incident — that's about to send a wave of patients to the hospital from outside. The disaster plan activates ahead of patient arrival, not after.

Emergency DepartmentAdministration / Incident CommanderFacility ManagementExternal ambulance & government liaison

Code Grey

Utility or system failure (power, water, medical gas)

Called for a critical utility failure — power, water, medical gas, or IT systems — the kind of event NABH's FMS chapter requires a documented back-up and downtime plan for, tested and not just written.

Facility & EngineeringBiomedicalIT / Information ManagementNursing (affected units)

Code Silver

Person with a weapon / hostage situation

The most serious security code — someone on the premises is armed or holding hostages. Areas are locked down, uninvolved staff and patients are moved away, and police are engaged immediately.
