When safety has top priority
In comparison with open spaces and buildings, the escape possibilities in underground transport systems are very largely limited. If safety standards are not observed, a fire can have catastrophic consequences.
The development of smoke in the case of a vehicle fire is relatively harmless outdoors. In a tunnel, however, it can have deadly consequences. The spreading speed of poisonous fire gases within the tunnel far exceeds the human speed of escape.

Most people who have died in fires in underground transport systems were usually victims of smoke inhalation.
A burning car generates fire loads of up to 5 MW, a lorry even over 100 MW. Fire loads such as these have destructive effects on the supporting structure of the tunnel and lead to damage costs in millions.
