An explosion at an Ohio oil refinery blew out windows at homes in Lima on Saturday and could be felt at least 10 miles away but resulted in no injuries, police said.
All workers were accounted for after the blast at the Husky Lima Refinery, according to police.
The blast triggered a fire that burned into mid-afternoon and sent black smoke billowing into the air above the refinery. Crews were monitoring the air to make sure there was no danger to those nearby.
Those tests had not detected anything hazardous in the first hours after the explosion, said Heidi Griesmer, a spokeswoman for the Environmental Protection Agency.
The fire was mostly out 10 hours after the 6 a.m. explosion, said Husky Energy spokesman Mel Duvall.
