Dear Gautam,
There are two norms: TAC norms and NBC (National Building Code). The Tariff Advisory Committee no longer exists, but their norms serve as the basis for fire-related calculations in India. The NBC pertains to the construction of buildings, focusing on safety features.
I'm attaching the NBC code (fire-related pages only) for your reference and that of your friends. By the way, which industry are you interested in?
If you require more details on fire extinguishers, you should consult:
- IS 2190 (selection of fire extinguishers)
- IS 2189 (fire alarm systems)
Additionally, for fire extinguishers, you can refer to the NFPA standard, specifically NFPA 10. You can access this standard for free on the NFPA website, but you will need a Flash player to view it.
Regards.
