In-Depth Information
The emergency services have emergency plans which are recorded as strat-
egy scripts. These describe exactly who acts with what means.
The tunnel control room has a direct telephone line to the central control
room of the emergency services. In cases of disaster, the tunnel operator can,
per tunnel tube, activate a pre-programmed emergency programme via an
emergency button. With this the following scenario comes about:
- both tunnel tubes are closed to incoming traffic with barrier gates;
- the ventilation in the disaster tube blows the smoke and possible haz-
ardous fumes out in the driving direction;
- the tunnel lighting is switched to a maximum level;
- the left-hand driving lane in the tunnel tubes is marked with a cross, and
the speed of the traffic in the right-hand driving lane is reduced to
30 km/hour;
- the emergency doors to the cross connections are unlocked and the ven-
tilation in the cross connections is started up;
- escape routes to the cross connections are indicated;
- motorists in the non-incident tube are warned about pedestrians on the
road;
- the fire extinguishing pumps start up.
The tunnel operator can always manually intervene in the emergency
programme, per individual system.
