Asbestos inquiry

THE Sydney Opera House has launched an investigation after more than 50 workers were potentially exposed to deadly asbestos for almost a week during renovations.

Workers for the company tasked with the $200 million renovations, Laing O’Rourke, located the asbestos during the construction of an accessibility tunnel alongside the Joan Sutherland Theatre, a Sydney Opera House spokesman confirmed on Thursday.

The Electrical Trades Union has accused the builder of not observing safety protocols after the discovery on Monday July 24.
