SYRACUSE, N.Y. — A chemical spill that shut down an industrial section of Hiawatha Boulevard in Syracuse on Monday was due to an accident involving Glyoxal, a potentially hazardous chemical used in packaging, according to the Syracuse fire chief.

About 2,500 gallons of the chemical spilled out of a pipe due to a “mechanical failure” shortly after 5 p.m., Fire Chief Michael Monds said Tuesday. The street was closed between Hiawatha Place and Seventh North Street. Read more.
