Dad wants answers from insulation probe A grieving father hopes the royal commission into Labor's bungled home insulation program will spare other families the pain he has endured. The program has been blamed for the deaths of four installers, including three in Queensland, as well as extensive property damage. The commission, to be headed by Brisbane lawyer Ian Hanger QC, will begin preliminary hearings in Brisbane on December 23. Lawyer Bill Potts is representing Murray Barnes, the father of 16-year-old installer Rueben Barnes who was electrocuted while laying batts in the ceiling cavity of a house at Stanwell in Queensland. He had only started working with his insulation company employer three weeks earlier. Mr Potts says Mr Barnes wants the former government to take responsibility for its actions. He simply wants to know why, not how he died. He simply wants to know what the government did, why they did it, to see if some good can come from his son's death," Mr Potts told the ABC on Friday. That is to prevent other young men from effectively being butchered for what appears to have been rushed legislation. Mr Potts said the royal commission is not just about inquiring into the deaths of the installers, "but the circumstances that surrounded the deaths, the government decisions, the ministerial input." Former prime minister Kevin Rudd launched the $2.8 billion "pink batts" scheme in 2008 to inject cash into the economy during the global financial crisis - and it ran until 2010. In July, a Queensland coroner found the rushed roll-out of the scheme was a significant factor in the deaths of Queensland batt installers Barnes, Mitchell Sweeney, 22, and Matthew Fuller, 25. In NSW, 19-year-old Marcus Wilson, died on his first day on the job after suffering heat stroke. The royal commission will be headed by Brisbane Queen's Counsel Ian Hanger and report back to the government by June. It will hold a preliminary hearing in Brisbane on of December 23. The lawyer representing the Sweeney family says Mitchell's death could have been prevented had his employer taken simple, inexpensive safety measures. The 22-year-old was working for Titan Insulation when he was electrocuted in February 2010 while installing foil insulation using metal staples at Millaa Millaa, in far north Queensland. His parents also don't want to see another family go through what they have. "It is important that the commission looks at the role of employers in the implementation of the scheme," Maurice Blackburn principal Peter Koutsoukis said in a statement on Friday. There were significant failures on the part of his employer to ensure he was operating in a safe work environment. Titan Insulation was fined $100,000 for unsafe practices in 2011.
