A hazardous materials alert has been issued in southern Jefferson County after a train derailed in the area and emitted a strong chemical odor. MetroSafe spokeswoman Jody Duncan said about 20 houses were being evacuated Monday morning in southern Jefferson County near the town of West Point because multiple chemicals spilled from the train.
Duncan said others in the area were being told to shelter in place.
Duncan said the train derailed about 6 a.m. EDT near the Ohio Valley Dragway on Dixie Highway and spilled multiple chemicals, including hydrogen chloride and hydrochloric acid, which can cause coughing, choking, and inflammation of the nose, throat and upper respiratory tract.
A Level 3 HazMat alert, the highest possible, has been issued for the area.
