Ethanol has been slowly leaking for more than five hours from two damaged containers in Melbourne as emergency services work to stem the flow.
The containers ruptured just before 8.30am on Monday when the truck that was carrying them struck a tree branch on Williams Road at South Yarra causing the containers to move and tip over.
"They've (the containers) tipped on their side and they're slowly leaking," MFB commander Dan Gatt told AAP.
"We can't use a forklift because of the chance of rupturing one of the containers".
While the ethanol level is deemed safe to the neighbourhood, the liquid is highly flammable and could spark if ruptured by a forklift.
