Fire extinguishers protect us, but who protects the fire extinguishers?
It's a question firefighters will have to ask themselves after a huge blaze erupted at a fire extinguisher factory on Chicago's Southwest Side on Thursday night.
About 150 firefighters battled the inferno, which burned for hours, according to DNA Info.
The fire didn't spread past the building and it was contained by midnight. There were no injuries reported.
"We have found no danger to the public," Chicago Fire Department spokesman Larry Langford told the Chicago Tribune. "The smoke is not causing any harm."
The two-story building housed several companies, including the fire extinguisher factory, CBS Chicago reports.
The cause is under investigation.
