Tunnelsafety can be defined as:
1. The prevention of potential causes of dangerous situations in tunnel structures.
2. The protection against potential dangerous situations in tunnel structures.
Tunnels are closed structures. That's why the consequences of a potential dangerous situation will be bigger than in open air. For example in case of a fire there are limited escape routes and emergency services are having more difficulty to reach the victims and fire source(s).
Not only people but also the environment in the tunnel surroundings need to be protected against hazardous gasses or acid fluids which accompanies fires. In the sense of air pollution an acceptable ambient air quality must be assured for people in the surroundings of tunnel portals.
Tunnelsafety is receiving increased attention due to the experience of tunnel accidents with large consequences.
Tunnelconstructions have to meet with legislation, terms and demands. Because several fields of profession are involved, it is inevitable that all parties must be controlled and managed in order to form a well-oiled-machine. This means that:
• Civil Engineering
• Mechanical Engineering
• Electraical Engineering
• Safety Organizations
have to be fine tuned in the (pre)designphase, the productionphase and during tunneloperation.
