The metro's safety solutions will represent the highest international standard. The starting points for safety designs are EU-level and international norms. The safety solutions to be employed will further be based on experiences from the Helsinki metro and surveys of metro accidents in different cities.
Factors promoting safety in the west metro will include platform screen doors which will prevent passengers from falling onto the tracks. The platform areas will be uniform spaces where special attention is paid to lighting. Long underground passages and shadowed areas will be avoided in spaces intended for the public.
Tunnel safety
The underground tunnels of the metro comprise two parallel, fire-compartmentalised tunnels, six metres in width. The metro tunnels will be excavated at a depth and place which are favourable from the rock engineering perspective. The distance between the tunnels will vary between 13 and 17 metres. At turnaround tracks the distance may at maximum be 50 metres. Tunnels excavated in rock are both economical and safe.
In exceptional situations passengers may exit the tunnel and enter the neighbouring tunnel through smoke traps in the connection tunnels. The distance between connection tunnels will be around 150-170 metres. Exit shafts will be located every 600 metres. The tunnels, which will be fitted with signal and safety lights, will have walkways with signposts every 25 metres.
The tunnel network will have a fire detection system. The metro will also be fitted with a video surveillance system, and the trains are to carry an audio system for emergency notices.
