IS 9972:1981 is the Indian Standard (BIS) for fire safety of hospitals. This code provides guidelines for the fire safety of hospitals, focusing on life safety, fire protection, exit requirements, and firefighting provisions. It covers both passive measures like fire-resistant construction and active measures like extinguishers and alarm systems to ensure the safety of patients and staff, many of whom may be non-ambulatory.
Specifies fire safety requirements for the design, construction, and operation of hospitals and healthcare facilities.
! This standard is outdated and has been superseded by the National Building Code (NBC) of India, Part 4. Always consult the latest NBC for current requirements.
! The principles of compartmentalization and protected escape routes outlined are fundamental but are detailed more stringently in the current NBC.
! Special emphasis is placed on protecting areas with immobile patients, such as ICUs and operating theatres, which remains a critical design consideration.

Key Differences
≠IS 9972:1981 is an old, prescriptive code. Modern international standards like NFPA 101 are regularly updated (every 3 years) and incorporate performance-based design options and risk assessments.
≠Modern international codes (e.g., NFPA 101) mandate automatic sprinkler systems for all new hospital construction, allowing for design trade-offs (e.g., longer travel distances). IS 9972 only recommends sprinklers for specific high-hazard areas.
≠International standards have a more advanced and detailed approach to smoke control, requiring smoke barriers, smoke compartments, and often active smoke management systems. IS 9972's approach is more basic, relying on passive compartmentation.
≠NFPA 101 and HTM 05-02 have detailed 'defend-in-place' strategies, recognizing that many hospital patients cannot be evacuated vertically. This involves robust horizontal exits and fire/smoke compartments. IS 9972 focuses on traditional total evacuation principles.
Key Similarities
≈All standards emphasize the fundamental concept of fire compartmentation, dividing the building into smaller areas with fire-rated walls and floors to contain a fire.
≈The requirement for a minimum of two separate means of egress (exits) from each floor or fire area is a common principle across all codes to ensure redundancy.
≈All codes mandate the provision of basic fire safety systems, including manual fire alarm systems, portable fire extinguishers, and emergency lighting for escape routes.
≈There is a shared emphasis on protecting escape routes, requiring corridors, lobbies, and staircases to be constructed of fire-resistant materials and kept clear of obstructions.

Is this code still mandatory for hospital design?+
No. It has been effectively replaced by the National Building Code (NBC), Part 4 'Fire and Life Safety', which is the current governing document.
What is a key principle for hospital fire safety in this code?+
A key principle is 'Life Safety' (Clause 4), prioritizing the protection of occupants, especially patients who cannot evacuate themselves.
What are the minimum exit requirements mentioned?+
The code requires a minimum of two exits for each floor or fire compartment, located as far as possible from each other (Clause 7).
Does this code cover fire alarm systems?+
Yes, it mandates the provision of manually operated fire alarm systems and automatic fire detection systems (Clause 5.3 & 5.4), referencing IS 2189 for details.
