The Tennessee Department of Transportation and the Cocke County Sheriff's Department said there is a one-mile radius evacuation of residents due to a leaking propane truck on SR 340 in Parrottsville in Cocke County.
During the leak, two Cocke County deputies were taken to Newport Medical Center for inhalation injuries and were released, according to Cocke County Emergency Agency.
The driver of the truck was flown to Johnson City for head trauma, Cocke County EMA said.
Spokesperson Mark Nagi said the propane truck overturned at Allen Chapel Road and began leaking.
CCSD told residents this is a mandatory evacuation within a one-mile radius of any direction due to the threat of an explosion.
Anyone that is evacuated and does not have a place to relocate can go to the Parrotsville Elementary school gymnasium, according to CCSD.
Nagi said there will be a long-term closure on SR 340, and a medical helicopter is en route.
As of 12:32 p.m., Nagi said the propane leak has slowed and the remaining product is being transferred. The evacuation zone is still in place.
