Practical Notes

This is the foundational dictionary for all Indian fire safety codes, especially the National Building Code (NBC) Part 4 'Fire and Life Safety'.

Use this standard to clarify definitions in design documents, regulatory submissions, and contracts to avoid ambiguity.

It officially deprecates misleading terms like 'fireproof', recommending 'fire resistant' instead.
