Four ACT workers have died since this time last year, including the latest on a Kingston Foreshore site in July when 21-year-old Ben Catanzariti was killed by a concreting boom.

Tasmania, with a similar sized workforce, had no deaths in the same period, as did South Australia, which makes up seven per cent of the national workforce.

The ACT Greens cited these figures in launching their industrial relations policy which they believe can turn Canberra into Australia's "Work Safety Capital".

Greens IR spokesperson Amanda Bresnan announced this morning the Greens would seek to raise $2 million a year to improve safety and train apprentices, particularly in areas of skill shortage. The money would be raised by lifting the building and construction levy imposed on developers, from 0.2 per cent to 0.3 per cent.

The Greens would also seek to provide $500,000 for better inspections of government construction sites, which they claim would help stop accidents and sham contracting and improve government procurement.

"Our vision must be to have no deaths on ACT worksites and we must commit to the funding and strategies that will achieve this," Ms Bresnan said.

Ms Bresnan said worksite bullying and issues around fatigue would be other targets for the party after the election.

"Today's commitment provides $1.2 million over four years to enhance Work Safe's capacity and expertise to prevent and respond to workplace bullying. The funding would also establish an expert committee on workplace bullying to help the government lead and innovate."

Ms Bresnan said the 0.1 per cent increase the Greens were proposing to the training levy was a small price to pay compared to the social and economic costs associated with a death on a work site.

“If you’re looking at the average project, if it was $100,000 it would add $100 to it’s cost,” she said.

“If it was $1million it would add $1000.

“It’s a very small price when you consider the impact that someone’s death has on a family and when you consider also the economic impact of worker’s compensation and insurance that goes along with that.”

The CFMEU has given its support to the Greens policy, saying it is long overdue.

ACT branch secretary Dean Hall said workplace safety policy wasn't being effectively enforced on sites and the Greens policy appeared to address the problem by training workers in workplace safety and delivering more inspections of sites.

“Safety performance will be vastly improved because workers will be given the skills to not only perform safely but protect themselves and other workers,” he said.

“With these new skills comes a hidden benefit and that is that they will have greater job security, which will add to productivity.”

Mr Hall said workplace safety in the ACT had become too bogged down in paperwork at the expense of practical enforcement of safety laws on work sites.

“The facts and figures are there, the tragedies are laid out,” he said.

“Four families have been destroyed by workplace accidents in less than 12 months.

“We have to do something about it.”
