VOLUSIA COUNTY, Fla. - It took about an hour for Volusia County firefighters and other crews to put out a two-alarm fire that ripped through an industrial park Monday morning.
The fire started after 7 a.m. in DeLand.
Investigators said they are not sure what started the fire, but they are investigating if anyone was inside the building when it broke out.
Several of the tenants run businesses out of their storage spaces. It's unclear at this point if they will have to move out.
cabinet-maker Gerald Burkholder said, "I'm real worried about what's in there and what's left."
Officials said three storage units were destroyed, including one that housed a painting booth, which is a possible source for small explosions heard in the building while firefighters tried to extinguish the blaze.
"There were a couple of reports of some small explosion that we're going to have to sift through there and find out exactly what was in there," Ebanks said.
"With any type of storage unit, you never really know what's stored in there. So right now, they're just going in there an overhauling it and making sure the fire is out," said Volusia County Fire Rescue Division Chief Paul Ebanks.
Fire Marshal's Office used heavy equipment to sort through some of the burned debris, making sure not to come in contact with potentially dangerous chemicals.
The cause of the fire remains under investigation.
