Firestopping in Healthcare: Special Considerations

Written by James Reid

Introduction

Healthcare settings present unique challenges for fire safety, especially when it comes to firestopping. In environments filled with vulnerable occupants, complex services, and strict hygiene protocols, ensuring that firestopping systems perform reliably is essential. 

Let’s explore the complexities of these building types, identify how to reconcile fire safety with infection control, and real-world examples you can learn from.

Why These Environments Are More Challenging

Firestopping in hospitals and similar institutions is more demanding than in many commercial or residential contexts. Some of the core challenges include:

  • 1. Dense Services and Penetrations
    Hospitals often have heavy mechanical, electrical, plumbing, medical gas, data, HVAC, and utility networks passing through walls, floors, ceilings and service risers. Each penetration is a potential fire path, so firestopping design must manage a high density of complex penetrations. 
  • 2. Frequent Modifications and Upgrades
    This sector evolves quickly – new diagnostic equipment, lab expansions, technology upgrades, rewiring, new ventilation systems. Each changes the risk factors, introduce breaches or undermine existing firestopping if not carefully managed.
  • 3. Vulnerable or Immobile Occupants
    In healthcare, many occupants (patients on life support, with limited mobility, under sedation) cannot evacuate fast or safely. Firestopping must be extremely reliable.
  • 4. Regulatory Complexity and Standards
    Healthcare buildings are regulated by the Health Technical Memoranda (HTM), the legislation for healthcare premises.
    Education buildings also have to conform to fire codes, building regulations, local authority standards, and sometimes extra scrutiny for occupant safety. 
  • 5. Hygiene, Infection Control, and Airflow Constraints
    Rooms and corridors may require controlled positive/negative pressure, clean air flows, sterile barriers, sealed environments (eg operating theatres, isolation wards). Firestopping must not conflict with these controls.
  • 6. Access Constraints and Maintenance Difficulties
    Accessing hidden voids, ceiling spaces, service zones or risers for inspection, repair, or upgrade may be difficult, especially in live healthcare areas or labs with restrictions. Traditional inspection methods (lifting ceiling tiles, opening access panels) can be disruptive.

Balancing Fire Safety with Infection Control & Operational Needs

In these sensitive environments, firestopping cannot be considered in isolation. It must coexist with other priorities like infection control, airflow management, contamination control, and continuity of critical services. Here are key considerations and strategies:

  • 1. Compatible Materials and Systems
    Firestopping products must be compatible with sterile environments. For example, fire-rated sealants and firestopping systems that do not shed particles, are easy to clean, resist microbial growth, and maintain performance under sterilisation or cleaning regimes.
  • 2. Pressure Differentials and Room Isolation
    Many healthcare or lab areas rely on negative or positive pressure to control airborne pathogens. The firestopping design must respect and preserve those pressure regimes. Seals must remain tight and stable even under differential pressure.
  • 3. Maintenance Protocols with Minimal Disruption
    Inspection, testing or repair of firestopping systems in live environments must be planned to minimise disruption. Phased work, isolation zones, temporary protective barriers, or redundant systems may be needed so that patient care, classes or experiments can continue.
  • 4. Interface with HVAC, Ventilation, Ductwork
    Ventilation systems and air ducts often penetrate fire-resisting floors or walls. Fire dampers, fire-rated ductwork, and coordinated firestopping systems must integrate with HVAC design. Also, in some buildings (eg hospitals), airflow must continue even during fire events (for smoke extraction or clean air), so fire/ smoke control must be carefully engineered.
  • 5. Risk-based Inspection and Lifecycle Management
    Given the dynamic nature of these facilities, firestopping systems require a robust maintenance regime, with scheduled inspection, recordkeeping, and proactive replacement of aged or degraded elements. 
  • 6. Collaboration between Disciplines
    Designers, fire engineers, infection control specialists, facility managers, and contractors must coordinate closely. Decisions about partitioning, access panels, service penetrations or airflow routes must include firestopping implications from the start.


Recommended Strategies & Best Practices
To mitigate risks in healthcare buildings, consider:
• Early integration in design: Firestopping plans must begin at the concept/design stage, not as an afterthought.
• Use of tested and listed systems: Each penetration or joint should be protected using firestopping systems that have been tested and certified for that application (eg wall/ceiling/floor assembly type, pipe or cable type).
• Maintaining an inventory & barrier register: Track all fire-rated walls, floors, penetrations, and installed firestopping systems; maintain documentation and drawings.
• Scheduled inspections & audits: Visual inspections annually or more frequently, with full audits every few years. Remediate any gaps or deteriorated firestopping elements. 
• Training and awareness: Maintenance teams, contractors and on-site staff should understand the impact of penetrations, sealant damage, repair work and modifications on firestopping integrity.
• Coordination with infection control & building services: Ensure that firestopping selection and design align with airflows, cleanroom protocols, pressure regimes and ventilation systems.
• Phased remediation strategies: For large buildings, plan firestopping upgrades in phases to avoid full shutdowns.

Conclusion


Firestopping in healthcare buildings must navigate more constraints, risks and interdisciplinary demands than many other types of buildings. But the stakes are higher: lives of vulnerable occupants, critical infrastructure and reputational risk. By understanding the peculiar challenges, planning proactively, applying tested systems, maintaining vigilance via inspections and repairs, and ensuring interdepartmental collaboration, building owners and facility managers can greatly reduce the hidden dangers of firestop failure.
