There was a Level 1 Haz Mat at 204 N. Artesian (Artesian and Lake) today as well. People’s Gas was digging and struck a 4-inch medium-pressure gas line almost directly underneath the Chicago Transit Authority (CTA) Green Line running down Lake Street. Engine 26, Truck 7, Battalion 12, Squad 2, and 5-1-1 (Hazardous Incident Team) made the run. Engine 26 led out a 2.5″ as a precaution, and Battalion 12 had the CTA shut down the ‘EL’ as People’s Gas made a quick shut down of the leaking section of pipe.
