Officials at the remote site of a derailed train carrying hazardous materials that sparked a fire in North Dakota briefly issued a shelter-in-place notice Sunday for area residents during cleanup.

The notice was issued as a precaution early Sunday after air monitors detected low levels of anhydrous ammonia after a railcar began venting during its removal from the site, said Andrew Kirking, emergency management coordinator for Stutsman and Foster counties in east-central North Dakota.
