Question

I am preparing a fire safety manual for our warehouse in Vashi. What are the key building occupancy groups (like Group A, Group B, etc.) defined under the National Building Code?

Under NBC 2016, Part 4, buildings are classified into 9 occupancy groups based on hazard profiles:
- **Group A**: Residential
- **Group B**: Educational
- **Group C**: Institutional (Hospitals)
- **Group D**: Assembly (Theaters, Hotels)
- **Group E**: Business (Offices)
- **Group F**: Mercantile (Shops, Malls)
- **Group G**: Industrial (Factories)
- **Group H**: Storage (Warehouses)
- **Group J**: Hazardous (Chemical storage)
Each group has specific water storage, escape path, and pump capacity rules.
