A trial has commenced in Sydney into the fatal blast at Draytons Winery 5 years ago.
The District Court has heard Draytons Family Wines along with a smaller Drayton family company and a Hunter Valley Engineering company all failed in their duties to protect their workers before the fatal explosion in January 2008.
Winemaker, Trevor Drayton and boilermaker Eddie Orgo were killed when Mr Orgo began welding a stainless steel tank containing 9-thousand litres of ethanol.
