RIO DE JANEIRO, May 9 -- Construction at a section of Brazil's Arena Pantanal World Cup stadium has been suspended pending an investigation into a worker's death.

Muhammad Ali Maciel, 32, was the eighth worker to die at a 2014 World Cup stadium after he suffered an electric shock Thursday while installing lights at the venue in the western city of Cuiaba.

According to local labour ministry chief Jose Almeida, construction has been halted until the company responsible for the work, Etel, proves health and safety standards have been met.

"What happened in this sector can also happen in another because procedures might not have been followed. It's a preventative measure," Almeida said in a statement released by the public ministry of Brazil's Mato Grosso state.

According to the ministry, Maciel was performing an "atypical" duty without using appropriate safety equipment at the time of the accident.

The incident has raised fresh doubts about whether Brazil's stadiums will be ready in time for football's showpiece event, which starts on June 12.

Apart from ongoing work on its electric and lighting systems, Arena Pantanal is still awaiting the installation of several thousand seats.

Construction work is also ongoing at Sao Paulo's Itaquerao stadium, which will host the tournament opener Between Brazil and Croatia, and Curitiba's Arena da Baixada.

Arena Pantanal will host four World Cup group matches, the first being Chile's clash with Australia on June 13.
