MARYVILLE, Tenn. (WATE) – As many as 5,000 Blount County residents evacuated their homes on late Wednesday night after a freight train derailed carrying flammable and poisonous material caught on fire.

According to the Blount County Sheriff’s Office, a CSX train carrying liquid petroleum, a highly flammable and toxic gas, derailed at Mt. Tabor Road at Old Mt. Tabor Road around midnight.

Homes in the area were evacuated. Hundreds of people relocated to the Foothills Mall until they are able to go home. The Red Cross also set up shelter at Heritage High School for residents.

Officials told WATE 6 On Your Side a shelter will be open at 233 Curry Avenue for displaced pets.

Evacuations could last between 24 and 48 hours, according to deputies.

Seven law enforcement officers from the Blount County Sheriff’s Office and surrounding were treated due exposure to the fumes.

The Blount County Sheriff’s Office, Maryville Police, TEMA and emergency management are on scene.

CSX representative Lee Miller apologized to residents in a meeting at Heritage High School. He said environment and hazmat crews are on site “working diligently” to get the situation taken care of. He estimates residents will be able to come home Friday morning.

Personal hygiene items, baby wipes and food will be provided by CSX, according to Miller.

CSX is offering reimbursement for families. Lee said for residents to keep receipts and bring ID to verify address to make sure it’s within evacuation radius.

Miller did not answer questions about timeline, chemical danger or contamination radius.

If residents have questions, they can call 877-TELL-CSX.

The Blount County Sheriff’s Office warns residents south of Robert C. Jackson Drive to Friendsville refrain from drinking well water.
