A large-scale evacuation would create logistical problems for emergency services access due to abandoned cars etc. However, it is a possibility and procedures are in place for communication to motorists if it is necessary. Human Behavior Human behavior during tunnel fires must be considered by firefighters and may be unpredictable and impact on firefighting and evacuation strategies. The response of motorists is significantly dependent upon the information transmitted, as they wait instructions before making decisions. Motorists appear willing to stop and assist other motorists during an incident.
People modify their actions when receiving instructions from the appropriate authority figures.
A key component to prevent panic and move people in a coordinated and structured way is to send precise, clear and confident messages. There are adequate systems in the tunnels to deliver such messages, but require human intervention at a high level of training and skill to ensure coordinated management with all tunnel systems and emergency procedures. Summary The Citylink tunnels have a series of fire detection and suppression systems, life safety facilities and emergency procedures integrated with those of the Emergency Services procedures which make them amongst the safest road tunnels in the world. The project is an excellent example of designer's developers and builders of major infrastructure projects involving the Fire Service at all stages to ensure a satisfactory outcome in terms of life and fire safety.
