A chemical fire caused by a train derailment in Kentucky has been extinguished. People had been encouraged to evacuate but now are able to return to their homes, according to rail operator CSX late last week. “The fire is completely out,” CSX spokesperson Bryan Tucker said in a statement. The train derailed on Wednesday November 23, at about 2:30 p.m. The incident occurred near Livingston, Kentucky. CSX worked to clear the train cars and material at the site. The derailment and spilled chemicals started a chemical fire earlier in the week and prompted evacuations in the small town. State officials said Friday they were monitoring the air for traces of hydrogen sulfide and sulfur dioxide, but so far there had been none detected at the derailment site or the nearby town of Livingston since Thursday morning. The fire was extinguished on Thursday. “We’re now able to get in and begin safely removing cars,” Joe McCann, director of emergency management and hazardous materials for CSX, said at a briefing Friday. He said an access road was built to reach the derailment area and the crashed train cars were removed.
