WASHINGTON COUNTY, Ohio (WSAZ/WTAP) -- Three men were hurt in an explosion at a company in Washington County, Ohio Tuesday.
The explosion happened about 8:50 a.m. at Enviro-Tank Cleaning.
Ohio State Fire Marshal Larry Flowers said the explosion had nothing to do with the process of cleaning a tank, but something as simple as transferring gasoline.
"The truck that they were transferring fluids out of into a storage tank and what they feel very confident about is that during that process there was some vapors that were released and in that area there were several ignition sources and those vapors found its way to one of those ignition sources and then that created the explosion," says Flowers.
The fire marshal added that things things can happen with something as simple as static from a cell phone or light wind to push fumes into an ignition source.
The Washington County Sheriff's Office has released the names of the three men injured in the explosion.
Kevin S. McClain, 32, of Ravenswood, West Virginia, was flown to Cabell-Huntington Hospital, where he is in the burn center.
Fred Johnston, 53, of Belpre, and Justin Flesher, 33, of Belpre, were treated and released for their injuries.
