Gas buildup kills one, injures two in Augusta, Georgia
Welders in a shop in Augusta, Georgia, were welding a plate onto the outside of a non-pressurized waste water collection tank in preparation for installing a hand rail. The atmosphere was tested surrounding the tank, but the inside was not. The welders didn't know what the gas buildup was, but the air in the tank was combustible. One of the victims in the explosion that occurred at the DSM Resins plant in September, 2017, was working inside a tank when the explosion happened.
According to the Augusta, Georgia, fire department incident report, responding units were advised that the explosion occurred involving a stationary liquid tank with no visible fire. They were advised that there was one person inside the tank and one person missing.
