A HIA spokesperson said that in the event of a ban the organisation was calling for adequate industry consultation around phasing out its use.

All state and territory workplace safety ministers have backed a blanket ban of engineered stone following the release of Safe Work Australia’s October report,which said there was no level of crystalline silica safe for tradies in cutting the kitchen benchtop slabs.

The report was commissioned after an investigation by this masthead and60 Minutes this year revealed a growing number of workers were battling the debilitating symptomsof silicosis while state-based regulators failed to guard against the dangers associated with inhaling crystalline silica dust.

Federal Workplace Relations Minister Tony Burke is holding a meeting with state and territory colleagues on Wednesday,when a plan on blanket prohibition is expected to be worked out,including a timeline to end its use. A potential import ban is also expected to be discussed.

In advice prepared for the CFMEU,veteran silk John Agius,KC,and barrister Philip Boncardo said there was “a distinct possibility and indeed a likelihood” that employers who continued to expose workers to cutting engineered stone were breaching health and safety laws.

“Given that breathing in respirable crystalline silica presents a risk of death or serious illness,it is also our view that there is a distinct possibility,and indeed a likelihood,that an employer … that continues to use engineered stone and exposes workers and other persons to respirable crystalline silica will commit an offence,” the advice says.

“There may also be potential liability for … employers for industrial manslaughter where a worker or other person dies after being exposed.”

CFMEU secretary Zach Smith said the legal advice “should send chills down the spines of employers who continue to work with deadly engineered stone”.

“We knew using a product that kills as many as one in four workers who come into contact with it was immoral,” he said. “Now it’s clear that it’s also illegal.”
