Preventing economical damage
Fire damage to a tunnel always has enormous financial consequences. Of course, the repair costs are huge, but the effects on the infrastructure are even larger. Tunnels have been out of order for months after a fire. For example after the fire in the Channel tunnel the direct repairs cost some € 87 million the additional costs in lost business, replacement of infrastructure, materials e.g. train carriages bring the economic loss to € 211 million.
Economical damage can be prevented by:
- Enhancing the fire resistance of the structure
- Protecting ventilation ducts and systems
- Protecting power supplies and signalling cables
- Detection systems
