Practical Notes
The primary challenge in museum fire safety is balancing aggressive fire suppression for life safety with the need to protect irreplaceable artifacts from water or chemical damage. Pre-action sprinkler systems are often the preferred solution in collection areas.
Passive fire protection, achieved through robust compartmentation (Clause 6) and high fire-resistance rated construction (Clause 5), is the most critical first line of defense.
This code should be read in conjunction with the latest National Building Code (NBC) of India, Part 4 - Fire and Life Safety, which may contain more recent or stringent provisions.
