Airport terminals combine massive occupancy, complex geometry, and critical operations. Fire engineering must ensure passenger safety without disrupting aviation.. Airport Terminal Fire Engineering Modern airport terminals are among the largest and most complex public buildings, handling millions of passengers annually through interconnected spaces with varying risk profiles. Unique Challenges Occupancies of 10,000 50,000 people at peak times 24/7 operation with no planned shutdowns Security requirements constraining escape routes Duty free retail with high fire loads (alcohol, cosmetics) Baggage handling systems with combustible luggage Fuel storage and aircraft refuelling in proximity International regulatory requirements Fire Safety Zoning Landside (pre security): Check in halls — large open volumes, high occupancy Retail concourses — standard retail fire safety requirements Car parks — increasingly EV charging risks Hotel and conference facilities — sleeping risk Airside (post security): Departure lounges — high occupancy with limited escape options Gate rooms — dead end conditions with single direction escape Duty free retail — concentrated alcohol and cosmetics fire loads Baggage reclaim — mechanical handling systems with combustible items Smoke Control Design Airport terminals typically feature large volume spaces requiring: CFD validated smoke control design Smoke reservoirs in roof structures Natural ventilation through operable roof lights Mechanical smoke extract in enclosed areas Pressurisation of escape stairs and corridors Detection and Suppression VESDA aspirating detection in concealed spaces (above ceilings, below floors) Video analytics for smoke detection in large volume spaces Sprinkler protection throughout (NFPA 13 or BS EN 12845) Foam suppression in baggage handling areas Gas suppression in IT/communications rooms Evacuation Challenges Security screening creates bottlenecks during evacuation Reverse flow through security (airside to landside) requires protocol Passengers with luggage move slower than standard evacuation models assume International passengers may not understand English announcements Aircraft gate areas may be dead ends requiring phased evacuation For airport fire engineering, contact Magnus Opifex.
