Underground transport stations provide a challenge to any company wishing to install fire protection systems. The typology of each area is different: ticket halls, shopping arcades, machinery spaces, electrical rooms, escalator and platforms.
The only common element is the enormous number of people who travel through these spaces at one time.
Crowd evacuation when a fire breaks out in an underground station is vital, and time is of the essence as the heat of a fire underground can become extremely intense in a matter of seconds.
The cooling water mist which is created within seconds of the system discharge provides a cloak of protection for people trying to gain access to escape routes and for rescue services. The water mist – or fog – will dampen the smoke and fumes, improving the quality of the air for evacuees.
