The Algonquin-Lake in the Hills Fire Protection District has issued a safety alert and said they are aware of an unknown chemical or burning electrical odor in the air early Sunday morning.
Fire district representatives said on social media they have received multiple 911 calls regarding an unknown odor described as a chemical or burning electrical smell in the air.
“Reports have been ongoing for approximately the last 12 hours and span a wide area, from central Illinois through Indiana and as far north as the Wisconsin border,” officials said in the social media post.
Officials said the source of the odor is unknown but appears to be coming from “a distance quite south of the area.”
Officials added they are actively monitoring the situation.
Officials added they are coordinating with regional partners and other agencies to gather additional information.
People who notice this odor should seek medical attention if they experience symptoms such as difficulty breathing, dizziness, nausea, or irritation, officials said.
People are also encouraged to call 911, officials said, but only if there is an immediate emergency or life-safety concern.
“We will share updates as more information becomes available,” officials said.
