GREENVILLE, Pa. — A 10,000-gallon fuel oil tank exploded at an industrial park on Monday and went flying across a road, killing a worker who was welding nearby.

The tank spilled 7,500 gallons of fuel and flooded a dike encircling the area, but the spill was contained, firefighters said.

The explosion happened Monday evening at Brownies Oil in the Reynolds Industrial Park in Mercer County. The industrial park is in Greenville, a remote borough of around 6,000 residents near the Ohio line.

The man who died worked for the oil company and had been welding near the tank when it exploded, Transfer Volunteer Fire Department Chief Phil Steele said. It was unclear what the man, who was from New Castle, was welding when the tank blew up.

The man died from blunt-force trauma to his head, and no one else was injured or killed, Steele said.
