A condominium building in Woodridge was evacuated Thursday after authorities found potassium cyanide in one of the units, according to the Chicago Tribune.
Potassium cyanide "releases hydrogen cyanide gas, a highly toxic chemical asphyxiant that interferes with the body's ability to use oxygen. Exposure to potassium cyanide can be rapidly fatal," according to the Centers for Disease Control and Prevention’s website.
A "small amount" of the toxic chemical was found in the unit, according to the Trib. The chemical was contained and removed. No one was injured.
The building was located near 83rd Street and I-355 in Woodridge.
