West metro smoke extraction fans will be tested in all shafts from Ruoholahti to Tiistilä in Matinkylä. The tested fans will be switched on and operated at full speed for a maximum of one hour. The tests will start running 26 April, on weekdays (Monday to Friday) between 08:00 and 16:00. During the test, a drone will be audible from the shaft. The sound will be stronger when the fans are operated at full speed. Dust may also be blown out from the shafts.
A total of 32 smoke exhaust fans have been installed in the Ruoholahti–Matinkylä section. In case of an emergency, the fans will be used for blowing smoke out through the shafts from underground facilities.
The first phase of Länsimetro to Matinkylä will open to traffic on 15 August 2016.
