Asbestos fears halts NBN work

Federal workplace safety regulators have reportedly ordered a halt at several National Broadband Network construction sites amid asbestos contamination fears.

Comcare has told News Limited it issued stop-work orders at multiple locations, and expected to issue more in connection with work on the NBN.

The move comes after a resident in Penrith, west of Sydney, contacted the NSW WorkCover authority with concerns that asbestos safety procedures weren't being followed.

News Ltd on Thursday reported Comcare had confirmed one case in which Telstra had not applied proper risk assessments to its work on the 'pits' that are crucial to the network.

In addition to the Penrith incident, News Ltd said there were allegations of asbestos release at work sites in Ballarat, in Victoria, and in Hobart.
