RIO DE JANEIRO, Jan 19 (Reuters) - Three workers were seriously hurt in an explosion at Petrobras' 323,000-barrel-a-day Landulpho Alves Refinery outside Salvador, Brazil, the union representing workers at the plant said.
The explosion at Brazil's second-largest refinery on Sunday is the second serious accident in a week at the plant, which is owned by Petroleo Brasileiro SA, as state-run Petrobras is formally known. The accident in a hydrogen vessel seriously burned the victims, the union said on Sunday. (Reporting by Jeb Blount; Editing by James Dalgleish)
