IS 11460:1985 is the Indian Standard (BIS) for fire safety of libraries and archives. This code provides guidelines for fire prevention, life safety, and fire protection in libraries and archives. It details requirements for building construction, storage arrangements, fire detection and suppression systems, and operational procedures to protect valuable collections and ensure human safety.
Code of Practice for Fire Safety of Libraries and Archives
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
Practical Notes
! This standard is from 1985 and should be used in conjunction with the latest version of the National Building Code of India (SP 7), specifically Part 4 on Fire and Life Safety, which may contain more current requirements.
! For protecting irreplaceable materials like rare books or archives, gaseous fire suppression systems (clean agents) are strongly recommended over water-based sprinklers to avoid water damage during a discharge.
! Strict adherence to housekeeping (Clause 9) and limiting combustible materials is a low-cost, high-impact measure to enhance fire safety in these high-risk occupancies.

Key Differences
≠IS 11460 is highly prescriptive (e.g., fixed fire resistance ratings), whereas modern codes like NFPA 909 incorporate performance-based design options, allowing for engineering solutions tailored to specific risks.
≠NFPA 909 strongly mandates automatic sprinkler systems as the primary protection for collections, reflecting modern confidence in sprinkler technology. IS 11460 (from 1985) presents them as an option alongside gaseous systems, showing a historical apprehension about water damage.
≠Modern standards like NFPA 909 have extensive and detailed requirements for smoke management and control systems, which IS 11460 addresses in much less detail.
≠IS 11460 does not explicitly mandate a formal, documented fire risk assessment process, while it is a fundamental requirement in NFPA 909 to determine the appropriate level of protection.
Key Similarities
≈Both IS 11460 and international equivalents are founded on the principle of compartmentation, using fire-rated walls, floors, and doors to limit fire spread.
≈All standards mandate the use of automatic fire detection systems (e.g., smoke detectors) to provide early warning to occupants and initiate a response.
≈The requirement to provide adequate, clearly marked, and unobstructed means of egress for life safety is a core tenet across all compared standards.
≈All standards emphasize the importance of controlling ignition sources, including proper electrical system design, maintenance of heating equipment, and control of hazardous operations.

Clause 6 - Fire Detection and Extinguishing Arrangements
What is the minimum fire resistance for walls separating a library from another part of a building?+
The enclosure walls should have a fire resistance rating of not less than 2 hours (Clause 4.2.1).
What is the maximum allowed height for book stacks?+
Single-tier book stacks should not exceed 2.2 m in height (Clause 7.2.1).
What kind of fire suppression system is recommended?+
Automatic sprinkler systems or automatic gaseous (carbon dioxide/clean agent) systems are recommended, especially for compact storage areas or those with highly valuable collections (Clause 6.3).
Is smoking allowed in libraries or archives?+
No, smoking and carrying open flames are strictly prohibited in all areas where records are stored or used (Clause 9.3).
