A suspected nitric acid leak has shut down nearly half of Port Botany's container wharves.
The DP World section of the wharf had to shut early this morning after a possible chemical leak was detected on the container ship California Senator, NineMSN reports.
According to Fire and Rescue NSW several 1000 litre drums containing nitric acid, a chemical used in the manufacture of explosives, were found to be leaking.
"We’re not sure how much has leaked into the container itself," Fire and Rescue superintendent Paul Bailey said.
"We're removing the container from the ship. We're trying to get into the container."
HAZMAT crews are currently working to determine how serious this breach may be.
The leak was initially discovered while the ship was still out at sea.
