ESTERO, Fla. A Hazmat situation in Estero wrapped up late Tuesday night after authorities determined the chemicals found inside a storage container pose no threat. They've been probing a storage container at Corkscrew Village Self Storage near the intersection of US 41 and Corkscrew Road

The potentially hazardous materials could have been anything, so crews sent a robot from the Lee County Sheriff's Office inside the unit, which was able to safely determine there was no threat.

It's unclear what exactly those benign chemicals were. The unit in question had been sold at an auction, and the new owners went in to find several large drums and containers.

Fire and Hazmat crews closed off the area for several hours as a precaution. A professor from Florida Gulf Coast University on scene was able to test the sample and determine just how dangerous it was.
 
We still don't know what exactly was inside those drums or how long they were there. Crews spent the rest of the evening in cleanup mode to ensure the safety that unit and those around it.
