LOVELAND, Ohio --
Loveland's fire chief said something Rozzi's workers didn't know was under their feet was partly to blame for an explosion that injured two workers Friday.
Chief Otto Huber said that workers were using a Bobcat in an old barn on the property when the Bobcat knocked over a container of picric acid.
Huber said the acid soaked into and under the floor of the barn, where it reacted with some sort of old military ordnance, causing the blast.
The workers had no idea there were explosives under the barn, Huber said.
Bomb squads removed the unexploded ordnance and took it away to be detonated at another site.
Huber said the injured workers have been released from the hospital.
