Petrobras' strike-hit P-40 platform shut after gas leak

The leak happened as the workers' strike has spread, forcing Petrobras to adopt contingency measures on a number of platforms, including at the country's highest-producing Buzios field in Santos basin, Adaedson Costa, the secretary general of local union FNP, told Reuters on Thursday.

The strike has also reached several refineries, four thermal plants and two biodiesel plants, FUP union said in a statement.
