Ternium reported a thermal-shock reaction Monday at Planta Guerrero in San Nicolás. The company said water came into contact with slag at about 14:15, creating a noise that could be heard nearby. Its firefighters responded, authorities were notified under company protocols, and Ternium said there was no danger to the community or the environment.
The incident drew attention because the plant sits inside the metropolitan industrial fabric, close enough for neighbors to hear the reaction. The reports reviewed did not identify injuries, evacuations or material damage.
Why it matters
For industrial operators in a dense urban corridor, the first read-through is operational clarity: explain what happened, confirm the immediate risk assessment and keep the surrounding community informed.
The other side
Residents heard a strong noise and were concerned. Ternium’s account attributes it to contact between water and slag and says its response followed safety procedures, with no community or environmental risk reported.
What to watch
There is no reported change to the plant’s production schedule in the coverage reviewed. Any further update would likely come through Ternium or local authorities if the company has additional technical detail to share.
