Workplace safety minister Mick Gentleman says he won't pre-empt the findings of a probe into the death of a construction worker last week by committing prematurely to workplace safety reform.
A 62-year-old Sydney man died when a crane carrying a generator tipped on its side at the site of the new University of Canberra public hospital on Thursday night.
The Aikman Drive work site remains closed as WorkSafe ACT continues its investigation into the fatality which was the first on an ACT worksite since 2012.
But the mother of the last man killed on a Canberra construction site has renewed her calls for exclusion zones around equipment like cranes and booms.
Kay Catanzariti's 21-year-old son Ben was killed when a faulty concrete pump boom collapsed on him at a construction site on the Kingston Foreshore in 2012.
"If there was an exclusion zone this man wouldn't have died and all of his work colleagues wouldn't be going through what they're going through. The laws need to change," Mrs Catanzariti said this week.
However Mr Gentleman said it was "too early to pre-empt any outcomes from this investigation".
"A comprehensive investigation is currently underway into the tragic death on a construction site last week," Mr Gentleman said in a statement.
"This investigation, conducted by WorkSafe ACT in cooperation with ACT Policing, will examine all aspects of the circumstances of the tragic event. Briefs to the coroner will be provided as part of the outcomes of the investigation."
Mr Gentleman said the issue of worker safety was a "priority for this Government" and that "industrial manslaughter laws in the Crimes Act 1900 in 2003 remain an important component of our work safety scheme".
Head contractor Brookfield Multiplex previously told Fairfax Media it was cooperating with authorities, unions and WorkSafe ACT in the investigation of last Thursday's incident.
Brookfield Multiplex's regional managing director David Ghannoum said the company remains focused on providing support to the dead man's family and colleagues.
It is understood the man's Canberra coworkers will be flown to Sydney for his funeral on Friday.
"We have maintained daily contact with the worker's family to offer our continued support and assistance and ensure all of their needs are met during this difficult time," Mr Ghannoum said.
"In addition to this, we have coordinated counselling services for all workers on the University of Canberra Public Hospital site, and have organised for on-site counsellors to be present when the site re-opens and work re-commences."
