Structural fire protection
Industry and OEM
Impact and damage
Because of the spatial limitations of a tunnel, tunnel fires render all escape, rescue and repair measures rather difficult, and are hence regarded to be the greatest risk to people, vehicles and the tunnel structure itself. High-performance fire-protection systems are therefore required to satisfy the demanding structural fire-protection requirements in tunnels. These measures reduce the risk of injury, and avoid severe fire damage to the tunnel structure and, consequently, long closures (leading to a loss of income for tunnel operators and neighboring regions).
Requirements for structural fire-protection systems
Requirements for structural fireprotection systems are assessed on a project-specific basis using internationally recognised time-temperature curves (see page 6-7).
The structural fire-protection system ensures that, in the event of a fire:
Cladding with Aestuver® fire-protection boards
Aestuver® fire-protection boards are used as independently fixed or directly concreted (Permanent Formwork) cladding in underground transport systems and protects the entire concrete structure and reinforcement from harmful temperatures. The clear benefits of Aestuver® fire-protection boards for tunnel operators and transport agencies include the following:
