The Cause: Workers were using a grinding tool or welding torch on the exterior of a large used storage tank. The tank had not been properly purged of residual flammable vapors.
The Outcome: The ignition of the internal atmosphere caused a catastrophic overpressure event. Reports from the time indicate that while the explosion was massive, the workers in the immediate vicinity miraculously survived, though they sustained various degrees of injury.
