John C Kluczynski Federal Building,  230 South Dearborn Street, Chicago, IL.

Around 2:30 – Ambulance 32, Truck 1, and Battalion Chief 1 were first on scene.
HIT 5-1-1 and 5-1-11 arrived about 5 minutes later. I’m not sure what engine company is using D532 but this engine arrived 5 minutes after and left shortly after.
More pictures will be on my website.
