Baltimore firefighters are still at the Domino Sugar Factory in Locust Point after a fire destroyed the sugar-storage building.It is still a very active scene as remains of the sugar storage facility known as the sugar shack.Fire officials said they let a number of hot spots inside burn overnight because the fire is contained. Now, they are bringing in heavy equipment to help in putting out those hot spots.It isn’t the first time Domino Sugar has had a close call like this.It was a pretty impressive scene on Tuesday as smoke billowed from the Domino Sugar Plant. The heat was so intense, it managed to damage a fire engine.According to American Sugar Refining INC., the fire started in the building known as the sugar shack, which houses raw sugar for refining."I was on the phone talking to somebody and he said, 'Oh, your place is burning down.' I said, 'What are you talking about?' They said, 'Domino Sugar is on fire.' So, when I found out I said, 'Oh God, they’re not going to let me in,'" Domino Sugar employee Sabrina Washington said.Washington told 11 News she found out about the fire on the way to work as fellow employees on a different shift were being evacuated.Washington said the scene reminded her of back in November 2007 when there was a massive explosion inside the plant, after it’s believed a blow torch ignited sugar dust that was being cleaned from a dust collection unit."We allowed the fire to burn throughout the night just because it was in a contained area until the morning, like we’re doing, we’re waiting for some additional resources to help us better target the pit of the fire," Baltimore City Fire Department spokeswoman Blair Adams said.On Wednesday, fire crews were still on the scene as light smoke could be seen still coming from the building.Those crews are targeting three areas where the fire still exists and will bring in cranes and excavation equipment to help in the firefighting efforts."We had the management team at Domino Sugar to call in for some heavy machinery so that they can move some of the metal and material out of the way in order for firefighters to make sure that they are able to target the pit of the fire," Adams said.Fire officials told 11 News there were no injuries and crews plan to be on the scene again overnight to monitor the situation.The cause of the fire is still under investigation
