Police say a suspected drug lab triggered a hazmat response and evacuations in South Burlington on Friday.

Police, firefighters and hazmat teams responded to the Edge fitness center on Eastwood Drive around 2 p.m. to investigate a suspicious odor coming from a car in the parking lot. The gym was also evacuated.

Hazmat determined a container in the car had ammonia, an ingredient used to make meth. But authorities later determined the owner of the car was making gasoline. No charges will be filed.

The road was closed for several hours.
