Please note: sources and currency
This page summarises topics commonly associated with the National Building Code of India (the 2005 and 2016 editions are often cited) and IS 2190. We have not treated these as the latest applicable requirements. Which edition and local rules apply to your building must be verified.
We do not reproduce clauses, tables or numerical limits. For authoritative text, use the Bureau of Indian Standards publication and your local fire authority.
Scope and terminology
What Part 4: Fire and Life Safety Covers
Part 4 of the NBC deals with fire and life safety in buildings: its scope and terminology, fire prevention, classification of buildings by occupancy and life safety. The aim is to reduce the chance of fire, protect people if one occurs and support effective firefighting.
Fire prevention
Classification of Buildings by Occupancy
The way a building is used is central to assessing its fire safety needs. Nine occupancy groups are commonly used. Occupancy influences fire load, how many people are present, how well they know the building and how easily they can leave.
Residential
आवासीय
Homes, apartments and other buildings where people live and sleep, so night-time warning and shared escape routes matter.
Educational
शैक्षणिक
Schools and colleges, with large groups of students who depend on staff-led, rehearsed evacuation.
Institutional
संस्थागत
Hospitals and care buildings where occupants may need help to leave.
Assembly
सभा / समागम
Places where many people gather, such as halls and multiplexes, where crowd movement and exit capacity are central.
Business
व्यावसायिक
Offices and professional premises with dense equipment and many daily occupants.
Mercantile
वाणिज्यिक / व्यापारिक
Shops, markets and malls with public footfall and high combustible stock.
Industrial
औद्योगिक
Factories and process facilities where materials and machinery define the hazards.
Storage
भंडारण
Warehouses and stores, where stored goods and stacking drive the fire risk.
Hazardous
खतरनाक
Buildings handling highly combustible, explosive or otherwise hazardous materials, needing specialised assessment.
Life safety
Getting People Out Safely
Life safety is about evacuation and protection of occupants. Relevant themes include clear exits, corridors, doors, staircases (including external staircases and fire escapes where applicable), protected routes, sensible travel distances and emergency preparedness. Specific values vary by occupancy and must be taken from the current authorised code.
Protection and detection
Systems That Support the Building
Detection and alarm systems provide early warning. Extinguishers, sprinklers, hose reels, risers, hydrants, tanks and pumps help control fire. Public address systems and signage guide people. Selection depends on the building and applicable standards.
Smoke and hazardous gases
Why Smoke Is So Dangerous
Smoke composition depends on what is burning, and smoke exposure can be life-threatening. The gases below are commonly named. This is an educational overview, not a complete toxicology reference.
Carbon monoxide (CO)
कार्बन मोनो ऑक्साइड (CO)
A colourless, odourless gas. When inhaled it displaces oxygen in the blood and can cause suffocation.
Hydrogen cyanide (HCN)
हाइड्रोजन साइनाइड (HCN)
Released when materials such as plastics, silk, nylon and wool burn. It prevents the body's cells from using oxygen.
Carbon dioxide (CO2)
कार्बन डाईऑक्साइड (CO2)
Produced in large quantities by fire. Not directly poisonous at ordinary levels, but it lowers oxygen and can cause breathlessness.
Nitrogen oxides (NOx)
नाइट्रोजन ऑक्साइड्स (NOx)
Formed when some chemicals and synthetic fabrics burn. They can seriously damage the lungs.
Sulfur dioxide (SO2)
सल्फर डाईऑक्साइड (SO2)
Released from burning rubber and some plastics. It has a sharp smell and irritates the eyes, nose and throat.
Acrolein and formaldehyde
एक्रोलिन और फॉर्मेल्डिहाइड
Found in smoke from burning wood, paper and cloth. They harm the respiratory system.
