OSHA is investigating a fatal fire at a South Dakota ethanol plant that killed one worker and injured another at a biorefining plant. The cause of the fire hasn’t been determined, but OSHA says the worker who died was welding inside a tank at the time. The welder was flown to a Minnesota burn hospital, where he died. The other worker was treated at a hospital and released.
In late April, OSHA issued fines against two companies when a storage tank a worker was welding on exploded and killed him. South Dakota Soybean Processors of Volga was fined a total of $25,510 and CCM Welding Repair and Fabrication of Minneota, Minn. was fined $11,200. Neither company measured the flammability of the soap stock inside the tank, vapors from which caught fire and caused the explosion.
