We would like to inform you that sirens will be heard on our premises during the night of Sunday, March 22, to Monday, March 23. This is due to a maintenance shutdown of Blast Furnace B on March 23, 2026. 

The shutdown is scheduled for the night between Sunday and Monday, with mandatory sirens sounding between 2:00 a.m. and 2:30 a.m. and between 4:00 a.m. and 4:30 a.m. The system is scheduled to be restarted on Monday evening, March 23, between 10:30 p.m. and 11:30 p.m.

The sirens are necessary to signal that all employees on our premises must take cover and to safely alert everyone to a potential gas hazard. There is no risk to nearby residents.
