Every day, work takes place in an energised environment at the Tihisenniemi substation extension. Safety cannot be compromised, as an electric shock always poses a significant risk.
With many working groups operating side-by-side on a main grid worksite, everyone must know exactly what work is underway and
which stage it has reached. Since the start of June, it has been mandatory to announce the need for additional earthing – this is one of the steps Fingrid has taken to ensure safety.
