Smoke extraction fans will be tested at the Sammalvuori metro depot on 10 February 2022 from 8 am to 4 pm. During the testing, a whirring sound may be heard in the vicinity from time to time around the Sammalvuori metro depot. We apologise for any inconvenience.
Smoke extraction fans are used in case of fire to blow smoke away from the underground facilities along fire-compartmented routes 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. All in all, 15 smoke extraction fans have been installed on the Matinkylä–Kivenlahti section.
