An ammonia leak forced the evacuation of a business on Chicago's Southwest Side Saturday. It happened Saturday morning at Preferred Freezer at 45th Street and Ann Lurie Place.

A man was working on the cooling system when a leak caused the ammonia to spray and hit him. He was taken to a hospital in stable condition.

Nearly 30 workers were forced out of the building because of the leak. No one else was hurt.
