IS 12456:2004 is the Indian Standard (BIS) for fire protection of electronic data processing installation - code of practice. This code specifies requirements for fire protection in Electronic Data Processing (EDP) installations like data centers and server rooms. It outlines measures for fire prevention, detection, and suppression, focusing on construction, electrical installations, and the use of automatic systems, particularly gaseous agents, to minimize damage to sensitive electronic equipment and ensure business continuity.
Fire Protection of Electronic Data Processing Installation - Code of Practice
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
Practical Notes
! Clean agent suppression systems (e.g., Novec 1230, FM-200) are highly preferred over CO2 in normally occupied areas due to life safety concerns with CO2.
! Close coordination between fire safety and HVAC design is crucial, as high airflow can affect smoke detector performance and requires careful placement or the use of aspirating smoke detection (ASD) systems.
! Strict housekeeping is paramount; no combustible storage is permitted in the EDP room, under the raised floor, or above the false ceiling.

Key Differences
≠IS 12456 is more prescriptive, whereas modern standards like NFPA 75 incorporate more performance-based design options, allowing for engineered solutions based on risk assessment.
≠NFPA 75 and EN 50600 have much more specific requirements for communications cable fire ratings (e.g., Plenum-rated CMP), while IS 12456 provides a more general recommendation to limit combustibles.
≠International standards strongly recommend or mandate Very Early Warning Fire Detection (VEWFD), such as air-sampling smoke detectors. IS 12456 permits conventional smoke detectors (ionization/photo-electric) without the same emphasis on early warning technology.
≠IS 12456 references Halon 1301 as a benchmark for suppression agents. Modern standards focus exclusively on currently available and environmentally acceptable clean agents (e.g., FK-5-1-12, HFCs, inert gases) and water mist systems, with detailed standards referenced (e.g., NFPA 2001, NFPA 750).
Key Similarities
≈All standards mandate the fundamental principle of creating a fire-rated enclosure for the EDP/IT area to provide separation and containment from other building areas.
≈There is a common emphasis on a layered defense strategy involving detection, suppression, and containment.
≈All standards recognize gaseous (clean agent) fire suppression as a primary and suitable method for protecting sensitive electronic equipment with minimal damage.
≈The requirement for automatic shutdown of power and HVAC systems upon activation of the fire suppression system is a common feature across all codes.
≈All codes require protection in concealed spaces, such as under raised floors and above suspended ceilings, if they contain combustible materials or are used as air plenums.

What is the required fire rating for the walls of a data center?+
The walls, floors, and ceilings separating the EDP area from other occupancies must have a fire resistance rating of not less than 120 minutes. (Clause 4.1.2)
Are water sprinklers recommended for data centers?+
No, gaseous fire extinguishing systems are preferred to avoid water damage to equipment. A pre-action sprinkler system may be considered as a secondary backup. (Clause 6.3.2)
What type of fire detection is required?+
An automatic smoke detection system is mandatory. For early warning, aspirating smoke detection (ASD) systems are highly recommended. (Clause 5.2)
What kind of portable fire extinguishers should be used?+
Portable extinguishers of either carbon dioxide (CO2) or clean agent type should be provided near exits and special hazard areas. (Clause 6.2)
