"A Chicago fire extinguisher manufacturing building collapsed after burning Thursday. We're told more than 150 firefighters were called to the scene that went to 3 alarms. First Deputy Fire Commissioner Charles Stewart III said the nature of the blaze made it difficult to reach the flames with water. "We had one engine feed another engine to another engine until we got water on the fire," he told WMAQ-TV. (UPI) Firefighters said no injuries were reported and the cause of the fire remained under investigation Friday." - Jessie

"The HazMat response that had been called because of the materials used to make fire extinguishers was canceled shortly before 4 a.m., but crews still had water pouring on the building in an attempt to tamp down hotspots underneath the rubble. A fire official said getting enough water to the structure proved difficult." - Jessie
