Tunnels and underground transport facilities are important means of communication, not only in terms of shorter journeys, but also increasingly out of consideration for the local population and the environment. Generally speaking, important underground transport links are expected to be available without any restrictions and to operate smoothly round the clock. Interruptions due to accidents, technical malfunctions or maintenance work quickly cause traffic jams and delays, and figure in transport policy statistics as economic losses.
When considering tunnels, it is usually in relation to road and rail infrastructure, however, use of the word tunnels can be slightly misleading, as the following details apply equally to pedestrian walkways, underground rail stations, underground car parks etc, in fact, to any concrete structure.
Fires in tunnels are a major hazard to human life and can cause costly damage to the infrastructure. The limited escape facilities and the difficulties encountered by intervention forces in gaining access call for extensive safety arrangements which must be complementary and mutually coordinated. |
The Promat tunnel boards combine a lot of advantages, such as resistance to hydro-carbon combustion pollutions, resistance to humidity, resistance to steam diffusion, high performance, resistance to frost- and deicing salt, resistance to mould growth etc,...
To safeguard lifes and to prevent huge material damages in a tunnel fire is a major objective without any complacency for Promat. |
