Germany’s TÜV SÜD has pulled out of conducting safety assessments of dams after the collapse of a Brazilian dam it had vetted killed almost 250 people in January, the industrial inspection firm’s chief executive told Reuters. The collapse of the tailings dam, which was operated by Brazilian mining company Vale SA, flooded the town of Brumadinho with mining waste water only four months after TÜV SÜD had vouched for the safety of the structure.
