This week's Green Visions features audio from the Thursday, August 2 press conference by the US Chemical Safety and Hazard Investigation Board (CSB).
Interim Executive Dr. Kristen Kulinowski and CSB Lead Investigator Mark Wingard provide an update on the investigation into the April 26th, 2018 explosion at the Husky Oil Refinery in Superior, WI. The CSB acknowledged the investigation is ongoing, and confirmed that the event occurred during a scheduled maintained shutdown, a process described as "significantly more hazardous" than the standard operation.
