A worker has died after being crushed by a shipping container at an industrial site at Sydney's Port Botany.
In what ambulance officers described as a "traumatic scene", the man, understood to be in his 50s, was discovered by fellow workers just after 10:00am on Wednesday.
The workers performed CPR on the man before paramedics arrived.
NSW Ambulance inspector Darren Hull said the man was in cardiac arrest.
"But unfortunately he didn't respond to treatment," he said.
Another worker was transferred to hospital to be treated for shock and a chaplain has been called in to help affected staff.
"It was a traumatic scene for all involved."
A friend of the deceased was at the scene and was extremely distressed by the tragedy.
He said the victim was an experienced worker at the depot.
The incident occurred at Tyne ACFS, a joint venture between ACFS Port Logistics and Tyne Container Service.
On its website it is described as "Australia's largest privately owned empty container park operator".
The shipping containers are empty and moved around at the depot with forklifts. The containers are stacked 42 metres high.
Tyne ACFS said it would be assisting NSW Police and workplace regulator SafeWork NSW in their investigations.
"Our sincere condolences go to the family, friends and work colleagues of our well-liked and respected employee. We are doing all we can to support his family and our workforce," the statement said.
The death comes amid a spate of work-related deaths and serious injuries across Sydney.
Earlier this month a man was killed after his head became stuck in a piece of machinery in Sydney's west.
It was one of three serious workplace incidents across the city on one day.
Last month, 38-year-old Mohamad Riche fell five storeys down a long shaft at the development site near Penrith.
