(Mandan, ND) — Authorities say the oil tank explosion in Mandan earlier this month was accidental. The Mandan Fire Department says the top of an empty fuel tank was tossed more than 100 yards in the explosion, damaging six nearby buildings. It happened around 8:45 a.m. on January 10th while maintenance workers were preforming “hot work.” Gray Oil says all tanks were empty at the time and operations were halted immediately after the explosion. They urge property owners who believe they sustained damage to file insurance claims.
