On July 29, 2008, Mr. John S. Bresland, Chairman and Chief Executive Officer of U.S. Chemical Safety Board (CSB) testified before the U.S. Senate Committee on Health, Education, Labor, and Pensions Subcommittee on Employment and Workplace Safety. He noted that since 1998, the year that the CSB was established, three out of the four deadliest accidents they have investigated were determined to be combustible dust explosions. Thirteen workers died, and 39 were injured, at Imperial Sugar refinery in February 7, 2008. Twenty-three people were burned from the fire and explosion, three of which were still hospitalized in a burn center after five months of treatment. At West Pharmaceutical Services in Kinston, North Carolina, six workers were killed, and 39 injured in a polyethylene dust explosion on January 29, 2003. The fuel for the explosion was a fine plastic powder, which had accumulated above a suspended ceiling over a manufacturing area at the plant and had ignited. And, at CTA Acoustics, Inc. in Corbin, Kentucky, seven people were killed and 37 were injured on February 20, 2003. This incident severely damaged a manufacturing plant of 302,000 sq. ft., and temporarily shut down four Ford Motor Company vehicle manufacturing plants for a time. Combustible phenolic resin dust had accumulated throughout the facility, and was the fuel for the explosion.
