Add CategoryA berth at the Port of Brisbane remains in lockdown after sodium cyanide spilt from two damaged shipping containers.
The incident occurred about 8am on Wednesday and has resulted in a 200m exclusion zone being constructed around one of the berths.
A Queensland Fire and Emergency Service (QFES) spokeswoman said scientists had determined the chemicals and the berth remained cordoned off.
About a dozen QFES emergency vehicles attended the site as a precautionary measure, she said.
“The chemical is sodium cyanide but the cause of the spill is undetermined,” the QFES spokeswoman told NCA NewsWire.
“An exclusion has been constructed as a safety precaution.”
The sodium cyanide spilt from damaged 6m containers.
The cordoned-off area is one of 29 berths at the port.
Ambulance and police crews were also on the scene.
