Practical Notes
This code is considered dated. Designers must primarily refer to the latest National Building Code of India (NBC), Part 4, which provides more current and comprehensive requirements for fire safety in all building types, including hotels.
The calculation of occupant load (Table 1) and ensuring adequate exit capacity and width (Table 2 & 3) is a fundamental first step in hotel fire safety design.
Requirements become significantly stricter for high-rise hotels (defined as buildings >15m in height), mandating features like automatic sprinklers, pressurized staircases, and dedicated fire lifts.
