The smoke extraction fans at the Matinkylä, Finnoo and Kaitaa metro stations will be tested overnight from 11.45 pm on 15 February until 5.00 am on 16 February. The fans to be tested are located in the stations at the following addresses:
- Kaitaa metro station, Iivisniemenkatu 5
- Finnoo metro station, Suomenlahdentie 64
- Finnoo metro station, Suomenlahdentie 62
- The block located at the western entrance to the Matinkylä station, Suomenlahdentie 9
During the testing, a whirring sound may be heard in the vicinity of the stations from time to time. The smoke extraction fans will also be tested at full power. The tests will be carried out at night when the metro is not running.
Smoke extraction fans are used in case of fire to blow smoke away from the underground facilities along fire-compartmented routes and into the outside air. There are smoke extraction fans in the metro line’s vertical shafts and at the metro stations’ eastern and western ends. The testing of smoke extraction fans is related to the testing of the West Metro’s Matinkylä–Kivenlahti section. The functionality of the systems is also always tested at the adjacent station, i.e. in Finnoo’s case, testing will also take place on the systems of the already operating metro station at Matinkylä.
All in all, 15 smoke extraction fans have been installed on the Matinkylä–Kivenlahti section. There are 32 smoke extraction fans on the Ruoholahti–Matinkylä section.
We apologise for any inconvenience caused by the testing.
