Healthcare premises present the most complex evacuation challenges — patients who cannot self-evacuate, 24/7 operation, and critical clinical equipment. A specialist guide.. Healthcare Fire Safety Complexity Hospitals are among the most complex buildings to fire engineer. The combination of vulnerable occupants, life critical equipment, hazardous materials, and 24/7 operation creates unique challenges. HTM 05 02: Firecode Health Technical Memorandum 05 02 is the primary guidance for fire safety in healthcare premises: Progressive horizontal evacuation — patients moved to adjacent compartment, not outside 30 minute compartments minimum, with some areas requiring 60 minutes Sub compartmentation — wards divided into sub compartments of 750m² maximum Bed space evacuation — design must facilitate rapid bed evacuation through doors and corridors Key Design Considerations Corridor widths: Minimum 2.1m (1.8m in Scotland) to allow bed evacuation Double doors at compartment lines Hold open devices on corridor fire doors (linked to alarm) Detection and alarm: L1 detection throughout (BS 5839 1) Staff alarm (not public alarm) to avoid patient panic Integration with nurse call systems Zoned alarm allowing progressive response Suppression: Not generally required by Firecode Increasingly specified in atria, atriums, and mixed use areas Specialist suppression in MRI suites (non magnetic systems) Specific Risk Areas 1. Operating theatres — high oxygen environments, flammable anaesthetic agents 2. MRI suites — cryogenic helium quench risk, restricted metal access 3. Pharmacies — flammable and oxidising chemicals storage 4. Kitchens — commercial cooking fire risks 5. Plant rooms — HV switchgear, generators, medical gas storage 6. Mental health units — ligature free, anti barricade design The NHS Challenge The NHS estate includes buildings from the 1940s to present day, many with: Inadequate compartmentation Complex extension and modification history Mixed construction types within single buildings Asbestos affecting fire safety upgrade works For healthcare fire engineering, contact Magnus Opifex.
