Fire Extinguisher Factory Catches Fire, Burns For Hours

A fire extinguisher factory in Chicago caught on fire late Thursday night. It's the definition of the cruelest irony, the fire raged for about three hours, apparently a warehouse full of extinguishers wasn't enough to stop it.

When firefighters got to the scene, they found there weren't enough hydrants around to get the water they needed to put it out. They made a chain of six fire engines, pumping from one to another, just to get enough water to finally kill the fire.

No one was injured, but the roof completely collapsed and the building was seriously damaged. Investigators are still trying to figure out what caused it.
