Hospital Fire Safety under the Building Code of Pakistan

A fire in a hospital is fundamentally different from a fire in an office or a shopping mall. In most buildings, the goal is simple: get everyone out quickly. In a hospital, many occupants cannot walk. Patients may be unconscious, on ventilators, in the middle of surgery, in traction, or newborns in incubators. Moving them down smoke-filled stairs is dangerous and sometimes impossible. That is why hospital fire safety in Pakistan must be designed around a different strategy, where the building itself protects patients long enough for staff to move them to safety.

Pakistan has seen several serious fires in hospitals and healthcare buildings, often started by electrical faults, overloaded air conditioners, or oxygen-enriched environments in ICUs. Most of these tragedies were preventable through proper design, construction and maintenance. This guide explains the fire safety principles for hospitals, how they relate to the Building Code of Pakistan and international standards, and the practical measures every hospital owner should build in.

🏢 About Hospital Design Hub

Hospital Design Hub is a specialist hospital design and construction company, established in 2000 and focused on healthcare infrastructure: design, construction, consultancy and project management, and the renovation and maintenance of hospital facilities. With more than 50 successfully completed projects, our team has worked on healthcare facilities across Pakistan, including projects such as LDMC, MCH Islamkot, King Edward Medical University / Mayo Hospital, and UOL Hospital Lahore.

Fire safety is built into every hospital we design and construct, from the fire strategy at concept stage to fire stopping and system testing on site.

🔥 Why Hospitals Need a Special Fire Strategy

Several factors make hospitals uniquely vulnerable in a fire:

• Immobile patients: ICU, OT, NICU, dialysis and many ward patients cannot evacuate on their own.
• Oxygen-enriched environments: oxygen makes materials burn far more intensely. ICU and OT fires can spread extremely quickly.
• Heavy electrical loads: medical equipment, air conditioners, heaters and chargers, often on overloaded or poorly installed circuits.
• Flammable materials: alcohol-based hand rubs, disinfectants, linen, mattresses, paper records and chemicals.
• 24-hour occupancy: fires at night happen with fewer staff on duty.
• Visitors unfamiliar with the building: attendants and families do not know escape routes.

For these reasons, international life safety codes such as NFPA 101 (Life Safety Code) treat healthcare occupancies with specific rules, and Pakistan’s own fire safety provisions in the Building Code of Pakistan, published through the Pakistan Engineering Council, also set requirements for buildings of this type. Local development authorities and fire departments enforce requirements during approvals and inspections.

🏥 The Defend-in-Place Strategy Explained

Defend-in-place does not mean “stay and wait”. It means designing the hospital so that:

1. A fire is detected early by automatic detectors and alarms.
2. The fire is contained in the room or compartment where it starts, by fire-rated construction and self-closing doors.
3. Smoke is kept out of neighbouring compartments by smoke barriers.
4. The fire is suppressed automatically by sprinklers (where installed) or manually by trained staff and firefighters.
5. Patients near the fire are moved horizontally through a fire/smoke door into an adjacent safe compartment on the same floor.
6. Full vertical evacuation down protected stairs happens only if necessary, with more time and less risk.

This approach requires careful planning of compartments at the design stage. Each floor with inpatients should be divided into at least two compartments, each able to hold patients from the other, with beds able to pass through the doors between them.

🧱 Fire Compartmentation and Construction

In our experience, the most common weakness in Pakistani hospitals is not the absence of fire doors, but poor fire stopping: fire walls that stop at the false ceiling, open holes around cable trays, and ducts without dampers. These gaps allow smoke to spread silently across an entire floor.

🚨 Detection, Alarm and Communication

• Automatic detection: smoke detectors in corridors, patient rooms, stores and plant rooms; heat detectors in kitchens and areas where smoke detectors would give false alarms.
• Addressable fire alarm panel: shows exactly which detector activated, helping staff respond quickly.
• Staged alarms: many hospitals use a staff alert first, followed by a general alarm, to avoid panic among patients and visitors.
• Manual call points: at exits and along escape routes.
• Integration: the alarm should release door hold-opens, shut down or switch relevant HVAC fans, recall lifts, and activate stair pressurisation where provided.
• Public address: clear voice messages help direct staff and visitors.

💧 Fire Suppression Systems

⚡ Electrical Safety: The Most Common Cause of Hospital Fires

Many hospital fires in Pakistan begin with electrical faults. Prevention starts at design and continues through maintenance:

• Properly sized cables and circuits for actual loads, including air conditioners and medical equipment.
• Quality circuit breakers and RCDs with correct ratings and discrimination.
• No daisy-chained extension boards: provide enough sockets at every bed and workstation.
• Dedicated circuits for air conditioners, a frequent cause of overheating.
• Separate electrical rooms in fire-rated enclosures, not used as stores.
• Thermal imaging surveys of panels as part of maintenance to detect hot spots.
• Proper earthing and lightning protection.

💨 Oxygen and Medical Gas Fire Safety

Oxygen does not burn, but it makes everything else burn faster and hotter. ICUs, OTs and COVID-era oxygen expansions have been associated with serious fires worldwide. Key design measures include:

• Zone valve boxes outside each ward, ICU and OT so oxygen can be shut off to an affected area.
• Area alarm panels showing pressure and supply faults.
• Good ventilation in ICUs to prevent oxygen build-up.
• Safe storage of cylinders in ventilated, fire-rated rooms away from heat and electrical equipment.
• Bulk oxygen tanks located outdoors with required clearances.
• Staff training on oxygen fire risk and the use of zone valves.

See our page on medical gas pipeline systems (MGPS).

🚪 Escape Routes, Corridors and Signage

• Corridor widths: patient corridors must allow beds to be moved and turned; international healthcare standards commonly require around 2.4 metres in inpatient areas.
• Multiple exits: at least two escape routes from each compartment and floor, with limited travel distances.
• Bed-sized fire doors between compartments.
• Emergency lighting on escape routes and in critical areas, with battery backup.
• Illuminated exit signs and clear directional signage in Urdu and English.
• Refuge areas in stair lobbies where required.
• Firefighter access around the building, with hydrants and access for fire tenders.

🛠️ How Hospital Design Hub Approaches Fire Safety

We integrate fire safety into every stage: a fire strategy at concept design, compartment planning in the architectural layout, coordinated fire alarm, sprinkler and hose systems in the MEP design, careful fire stopping and door installation on site, and full testing before handover. For existing hospitals, we carry out fire safety assessments and phased upgrades. See our fire safety and emergency systems page, our MEP services, and our guide to PHC layout guidelines. The Punjab Healthcare Commission also reviews safety arrangements during licensing.

🏥 Special Fire Risks in OT, ICU and NICU

Critical care and surgical areas combine the highest fire risk with the patients who are hardest to move. They deserve special attention:

• Operation theatres: the classic “fire triangle” of oxygen, ignition sources (electrosurgical units, lasers, light sources) and fuel (drapes, alcohol-based skin preparations) is always present. Allow alcohol preps to dry before draping, and train teams in surgical fire prevention. Each OT should be its own fire compartment where possible.
• ICUs: high oxygen use, many electrical devices and ventilated patients. Provide enough power outlets on medical supply units so extension boards are never needed, and design the ICU as at least two compartments or next to a safe refuge compartment.
• NICUs: incubators and warmers are electrical heat sources, and babies depend entirely on staff. Plan evacuation cots or trolleys and practise horizontal evacuation.
• Dialysis and day-care units: many patients connected to machines at the same time; staff need clear procedures for safe disconnection.

🔧 Fire Safety Management and Maintenance

A fire-safe design only stays fire-safe if it is maintained. Doors get wedged open, fire stopping is broken by new cables, extinguishers expire and alarm faults are ignored. Every hospital should have a written fire safety management plan and a maintenance schedule such as:

A named fire safety officer, a simple logbook, and management support are what turn fire safety from a one-time construction cost into a permanent culture of safety.

❓ Frequently Asked Questions

What is the defend-in-place strategy in hospitals?

It is a fire strategy where the hospital is divided into fire and smoke compartments so that patients can be protected or moved horizontally to a safe compartment on the same floor, instead of being evacuated down stairs immediately.

Which fire code applies to hospitals in Pakistan?

Hospitals should follow the fire safety provisions of the Building Code of Pakistan and local authority requirements, and designers commonly also use international standards such as NFPA 101 for healthcare occupancies.

Do hospitals in Pakistan need sprinklers?

Sprinkler requirements depend on building size, height and the applicable code and authority. Sprinklers are strongly recommended for larger and high-rise hospitals because they control fires early.

What is the most common cause of hospital fires?

Electrical faults, including overloaded circuits, poor wiring and overheating air conditioners, are among the most common causes, often made worse by oxygen-enriched environments.

How wide should hospital corridors be for fire safety?

Patient corridors must allow beds to be moved and turned. International healthcare standards commonly require around 2.4 metres in inpatient areas.

Why are medical gas zone valves important?

Zone valves allow staff to shut off oxygen to a specific ward, ICU or OT during a fire, reducing the intensity and spread of the fire in that area.

How often should hospitals hold fire drills?

Regularly, and for every shift including night staff, so that everyone knows alarms, escape routes, horizontal evacuation procedures and how to use extinguishers and zone valves.

Can an existing hospital be upgraded for fire safety?

Yes. A fire safety assessment identifies the highest risks, and upgrades such as fire stopping, new fire doors, alarm systems and electrical improvements can be phased while the hospital stays open.
