Several train cars carrying hazardous material are on fire after derailing in North Dakota

North Dakota public safety officials said several train cars carrying hazardous material are still on fire after about 25 to 30 derailed early Friday morning near Bordulac.

A train derailed in North Dakota early Friday morning and several cars carrying hazardous material are still on fire, according to local authorities. Foster County Emergency Management Director Andrew Kirking told CNN 911 was notified about the train derailment in the small town of Bordulac, about 140 miles northeast of Fargo, between 3:30 a.m. and 4 a.m. local time. Kirking said the train was carrying “intact hazardous materials,” so authorities have been monitoring air quality near the incident. Between 25 and 30 cars derailed. The North Dakota Department of Environmental Quality told CNN the train was carrying anhydrous ammonia, sulfur and methanol. Anhydrous ammonia, a gas widely used as a nitrogen-based fertilizer, can be extremely dangerous in high quantities, triggering explosions and causing dehydration and severe burns in humans, according to the Centers for Disease Control and Prevention. In a Facebook post, the department said it is monitoring the remediation and cleanup of the derailment. Kirking added local crews, including the Carrington Fire Department, regional hazardous material officials and Canadian Pacific also responded to the scene. Crews will work through the night Friday to extinguish the fires, cool the rail cars and remove hazardous material from them, Kirking said in a statement. They’re also preparing the site for heavy equipment to remove the rail cars.
