More than 300 people are feared dead after the dam failure near the town of Brumadinho released a torrent of mining waste into Vale’s facilities and a nearby community in Minas Gerais state.

The IndustriALL union, which represents mining and energy workers globally, said the Brazilian dam disaster is already recognized as the most deadly labor accident in the history of Brazil.

It follows on from the country’s worst environmental incident in November 2015 when the collapse of the Samarco dam, operated by Vale and BHP, resulted in the death of 19 people.

Both the Samarco and the Brumadinho disasters involve the failure of upstream tailings dams.
