DAYTON, Ohio (WDTN) — A scrap metal fire broke out in Dayton with smoke so heavy that it caused a local hospital to partially shut down its ventilation system on Monday evening.

The fire started within a scrap metal pile at Franklin Iron and Metal, located at 1939 East First Street.

According to Matt McClain, the District Chief of the Dayton Fire Department, something in the pile caught fire, although it is unknown what it was.

A passerby reported the fire after witnessing the dark smoke around 5:50 p.m.

The fire spread quickly but was contained to one area.

Dayton Children’s had to partially shut down segments of their HVAC system because of smoke headed toward their building. They have since been able to turn it back on.

There were no patient issues reported, but hospital workers are continuing to monitor the situation.

No injuries have been reported.
