Work was stopped on the Royal Adelaide Hospital construction site after the death of a 63 year old worker on Saturday.
The man was crushed between a scissor lift and the top of a doorway.
The accident was the second to occur on the site, the first fatal accident involving a scissor lift happened in November 2014.
The state’s health minister expressed his disbelief at the 2 fatal incidents which are only about 12 months apart.
South Australia has already suffered 5 workplace fatalities this year which is alarming considering that in 2014, 15 workers were killed throughout the entire year.
