Crawford Insurance was closed Thursday after a water heater exploded in the upstairs area of the building on Lower Market Street in downtown Maysville.
Jim Downing, a representative with the company, was the only person inside the building at the time of the explosion and received no injuries.
“It sounded like a bomb went off,” Downing said. “It happened about 7:30 (Thursday) morning. I was the only one there.”
After the explosion, debris could be seen all around the area of the hot water heater inside the building.
The Maysville Fire Department, Mason County EMS, Columbia Gas Company and Maysville Police Department responded to the call.
The intersection of Lower Market Street and West Second Street was blocked off until crews could check the area.
Maysville Fire Chief Kevin Doyle said the gas company was called as a precaution, though the water heater was electric.
Doyle said the exact cause of the explosion is unknown.
“We received the page for some type of explosion at this address,” he said. “When we found out it was a water heater, we assumed it was a gas heater, but found it was electric.”
According to Doyle, the water heater seemed to have been in working order before the explosion.
“Everything seemed to be hooked up correctly,” he said. “It had a pop off valve, like those water heaters are designed to be used with. Didn’t see any signs of destruction beforehand, but for some reason the water heater exploded.”
Doyle did say, however, that regardless of the reason for the explosion, the pressure relief valve should have stopped it.
“If the pressure relief valve was working properly, it wouldn’t have exploded,” he said.
Doyle said no one received any injuries from the explosion.
