Evacuation area includes a one mile radius from the derailment. Red Cross shelter at Heritage High School. Evacuation could last from 24 to 48 hours. Will update asap.



More than 5,000 residents were evacuated after a freight train carrying "highly flammable and toxic gas" partly derailed and caught fire early Thursday just outside Knoxville, Tennessee, officials said. 

Seven sheriff's officers were taken to hospital after breathing in fumes from the blaze, Blount County Sheriff's Department spokeswoman Marian O'Briant told NBC News. 

An evacuation zone is in place over a two-mile radius from the derailment, near Maryville, and could be in place for up to 48 hours, the fire department said

Two shelters are being opened for residents including one at a local high school, according to David Kitchen, senior disaster program Manager for the Tennessee Volunteer Region of the Red Cross.

The EPA says the substance is used in the manufacture of acrylic fibers and if inhaled in high levels can cause membrane irritation, headaches, nausea and kidney irritation. 

Up to three cars were ablaze, O'Briant said, but it was no immediately clear if the fire was under control. 

The CSX train was traveling from Cincinnati, Ohio to Waycross, Georgia and consisted of two locomotives, 45 loaded rail cars carrying mixed freight and 12 empty rail cars, company spokeswoman Kristin Seay told NBC News. One car derailed, she said.

The CSX tanker car carrying Acrylonitrile derailed just after midnight Thursday morning forcing the evacuation of more than 1,200 people.

According to Blount County Sheriff’s Office spokeswoman Marian O’Briant, one car was confirmed to have derailed at Old Mt. Tabor Road in Maryville. The car is on fire and the CSX train, containing nine total cars carrying the highly flammable and toxic colorless liquid, was being checked for any further derailments.

"So far they've evacuated about 100 people but they are getting ready to begin evacuations of camellia Trace Apartments, which has about 1,000 people," O'Briant said just after 2 a.m. from the evacuation site at Foothills Mall.

Evacuees are initially being sent to Foothills Mall. The facility is being opened to provide basic initial services. A Red Cross shelter is being set up at Heritage High School to handle an estimated 1,200 evacuees, who fall within the 1-mile safety radius of the derailment.

Members of Maryville Police, Maryville Fire, Blount County Sheriff's office, Blount County Fire, TEMA are responding to the scene. Responders near the scene are using hazmat gear and going door-to-door evacuating residences and businesses.

"They knocked on my door at 2:30 and woke me up," Rodney Duncan told The Daily Times.

Duncan, who owns a tiling business put on work clothes, packed up his dogs Maycee and Leo, and joined the evacuees at the mall.
"I guess I'll have to take them to work with me today."
According to O'Briant the evacuation may last 24 to 48 hours.

The cause of the derailment is not yet known. Officials have blocked several roads leading to the area as the evacuation proceeds, but a full list is not yet available.

Acrylonitrile is highly flammable and toxic. It undergoes explosive polymerization. The burning material releases fumes of hydrogen cyanide and oxides of nitrogen. It is classified as a Class 2B carcinogen (possibly carcinogenic) by the International Agency for Research on Cancer and is listed on the Environmental Protection Agency's website for Air Toxics.

O'Briant also reported that HEPACO, a company that specializes in train derailments was also on the scene. According to the company's website it is "one of the top environmental and emergency response companies in America."

The last derailment in the area was classified as "minor" in February of 2006 when a Norfolk Southern train derailed in Alcoa and blocked Lincoln Road. In 2005, The Daily Times reported a 95-car CSX train on Aug. 15, 2005, at West Hunt Road and Armona Road. The cause for that incident was later blamed on a buckled track caused by intense heat.
