Fire Safety in Underground Spaces: Car Parks, Basements and Tunnels

Below-ground spaces present extreme fire safety challenges including limited access, ventilation complexity, and delayed detection.. Underground Fire Safety Challenges Underground spaces are among the most challenging environments for fire safety design. Critical Design Factors Smoke extract ventilation (impulse jet fans vs. ducted systems) Fire resistance of structural elements (REI 120 minimum) Emergency lighting with 3 hour duration Clear wayfinding in windowless environments Fire service access and intervention routes Vehicle fire load calculations (including EVs) For underground space fire engineering, contact us.
