Designing fire resilient hospitals

Fire Safety State-specific Fire Service Regulations

Each state in India has its own fire safety regulations, which are in alignment with the NBC, but may have additional requirements specific to local hazards or conditions.

Key state-level requirements may include:

• Fire NOCs (No Objection Certificates): Hospitals must obtain a Fire NOC from the local fire department before construction or occupancy. This ensures the building has complied with all necessary fire safety standards.
• Inspection and Compliance: Hospitals are subject to regular inspections by the local fire authority to ensure ongoing compliance with fire safety regulations. Any deficiencies must be rectified immediately.
• Evacuation and Emergency Plans: Hospitals must have well-documented evacuation procedures for different types of emergencies, including fire evacuations. This includes safe evacuation routes, staff training, and a clear system for patient management during an emergency.

Key Fire Safety Systems for Hospitals

Hospitals require specialized fire safety systems due to the presence of vulnerable occupants, sensitive medical equipment, and complex infrastructure. Fire protection measures must ensure life safety, safe evacuation, and smoke control to protect patients, staff, and visitors.

1. Life Safety Considerations:

   • Vulnerable Occupants: Patients are often immobile, unconscious, or severely ill, making evacuation challenging. Systems must allow safe evacuation or shelter-in-place arrangements.
   • Specialized Patient Areas: ICUs, operating rooms, and burn units need enhanced fire protection due to sensitive equipment and the critical condition of patients.

2. Smoke Control and Compartmentalization:

   • Smoke Spread Prevention: Hospitals have multiple rooms and corridors where smoke can spread quickly. Smoke control systems such as pressurized stairwells and dedicated smoke extraction are vital.
   • Fire and Smoke Barriers: Fire-rated walls, floors, and ceilings help contain fires and toxic gases within one compartment, ensuring safety in patient rooms, emergency departments, and operating theaters.

   Hospitals require protection not only for patients and staff but also for critical infrastructure and equipment that support life-saving operations. Fire protection measures must ensure medical equipment and backup systems remain functional during emergencies.

3. Critical Infrastructure and Equipment Protection:

   • Medical Equipment Protection: Hospitals house expensive and sensitive medical equipment that must be protected from both fire and water damage. Fire suppression systems often use clean agents (like FM-200 or Inergen) instead of traditional water-based sprinklers to avoid harming electronics.
   • Life-Saving Systems: Backup power systems, such as generators, are crucial in healthcare facilities to keep ventilators, monitors, and lighting operational. Fire protection design ensures these systems remain functional and safeguarded during fire or power failures.

   Hospitals are high-occupancy facilities with complex layouts and multiple floors, making fire protection and evacuation planning especially critical. Fire safety systems must be designed to handle diverse patient care areas and vertical evacuation challenges.

4. High Occupancy, Complex Layouts, and Vertical Evacuation:

   • Large, Complex Buildings: Hospitals often span multiple floors with a mix of patient rooms, ICUs, operating theaters, emergency departments, and offices. Each area requires tailored fire detection, alarm, and suppression systems.
   • Vertical Evacuation: Multi-story hospitals need robust fire evacuation plans, including pressurized elevators for emergencies, refuge areas, and fire compartments to contain fires in areas where full evacuation is not immediately possible.

   Hospitals operate 24/7 and handle hazardous materials, making it critical to maintain active and reliable fire protection systems at all times. Emergency planning must also address areas where evacuation is difficult and risks from flammable substances are high.

5. 24/7 Occupancy:

   • Continuous Operation: Hospitals are occupied around the clock, unlike typical office buildings. Fire safety systems must remain active and reliable 24/7 to protect patients, staff, and visitors.
   • Critical Care Areas: Intensive Care Units (ICUs) and Operating Rooms (ORs) may be fully occupied at all times. Emergency plans must consider patients who cannot evacuate easily. Specialized suppression systems, such as wet pipe or dry pipe systems with advanced controls, are essential.

6. Dealing with Hazardous Materials:

   • Flammable Gases and Chemicals: Hospitals store and use oxygen, nitrous oxide, anesthetic gases, and other hazardous chemicals. Fire protection must ensure safe storage, ignition prevention, and damage control in case of a fire.

   Effective fire protection in hospitals goes beyond systems and equipment — it requires well-trained staff, strong coordination with local fire services, and integration with infection control protocols to safeguard patient health and safety.

7. Emergency Response Coordination:

   • Fire Drills and Training: Hospital staff must be trained to manage evacuations, assist patients, and respond to fire scenarios, including those involving hazardous medical gases and chemicals.
   • Coordinating with Local Fire Services: Hospitals work closely with fire departments so emergency responders are familiar with the facility’s layout, systems, and risks.

8. Risk of Infection:

   • Infection Control: Fire protection must be compatible with infection control measures. Smoke vents and HVAC systems must be designed to prevent the spread of airborne pathogens, especially in critical care and sterile environments like ICUs and operating rooms.

   Fire safety in hospitals requires not only detection and suppression systems but also reliable backup power, fire-resistant construction, and specialized protection for high-risk areas like ICUs and operating rooms.

   • Emergency Power Supply: Hospitals must have backup generators to keep critical systems such as life support machines, ventilation, and emergency lighting operational during fire incidents or power failures.
   • Fire-Resistant Materials: Construction materials like walls, doors, floors, and ceilings should be fire-resistant, particularly in sensitive areas such as operating theaters and patient rooms.
   • Smoke Management Systems: Smoke control or smoke extraction systems are essential to prevent the spread of smoke in ICUs, surgery rooms, and corridors, ensuring a safe environment for patients and staff.
   • Operating Rooms (ORs): Due to the presence of flammable anesthetics, specialized suppression systems (such as inert gas suppression) are recommended to minimize fire risks during surgeries.
   • ICUs and Critical Care Units: These areas require dedicated fire protection systems to safeguard patients on life support and protect sensitive equipment, especially where evacuation is not feasible.

   Fire safety in hospitals depends not only on advanced systems but also on their reliability and the preparedness of staff. Redundancy in critical systems and continuous training of personnel are vital to ensure effective emergency response.

9. Redundancy and Reliability:

   • High-Reliability Systems: Hospital fire protection systems must include redundancy across fire alarms, suppression systems, and emergency power systems. Backup systems ensure the hospital remains protected even if one component fails.

10. Staff Training and Fire Drills:

    • Training of Medical and Support Staff: All hospital staff — including doctors, nurses, and housekeeping — must be trained in fire safety procedures, evacuation protocols, and proper use of firefighting equipment.
    • Evacuation Drills: Regular fire drills should be conducted, especially in vulnerable areas. These drills must cover multiple scenarios, including safe evacuation of patients with mobility challenges.

    In hospitals, fire protection must ensure both system reliability and staff preparedness. Redundancy in critical fire systems and continuous training of personnel are essential for effective emergency management in healthcare settings.

11. Redundancy and Reliability:

    • High-Reliability Systems: Hospitals require fire alarms, suppression systems, and emergency power systems with built-in redundancy. Backup systems guarantee protection even if a primary component fails.

12. Staff Training and Fire Drills:

    • Training of Medical and Support Staff: All staff — including doctors, nurses, and housekeeping personnel — must receive fire safety training covering evacuation procedures and the correct use of firefighting equipment.
    • Evacuation Drills: Hospitals should conduct regular fire drills, especially in high-risk areas. Drills must account for multiple emergency scenarios and include evacuation procedures for patients with mobility challenges.
