At the request of the Board, the U.S. Chemical Safety and Hazard Investigation Board (CSB) investigation team examined all three incidents at Belle due to the severity and potential for even greater consequences and to understand how and why they could occur at a DuPont facility. DuPont is regarded as an industry leader in the advancement of health and safety practices and develops sound, respected, and widely used safe practice guidance. With such a reputation, the CSB was interested in examining the conditions at the Belle facility that led to a decline in adherence to the higher standard of performance that the corporation historically held.
