Four years ago today, a huge explosion and fire at the Imperial Sugar refinery northwest of Savannah, Ga., killed 14 people and injured 38 others. Fourteen of the injured suffered serious and life-threatening burns. The explosion was fueled by massive accumulations of combustible sugar dust throughout the packaging building. After the incident, here was one fascinating paragraph included in a U.S. Chemical Safety Board press release on the board’s investigation:
The CSB report said that the sugar industry was familiar with dust explosion hazards at least as far back as 1925. Internal correspondence dating from 1967 showed that Port Wentworth refinery managers were seriously concerned about the possibility of a sugar dust explosion that could “travel from one area to another, wrecking large sections of a plant.” Precursor events included a 1998 explosion at Imperial’s plant in Sugar Land, Texas; an explosion at the Domino Sugar plant in Baltimore in November 2007; and two sugar dust explosions in the 1960’s that killed a total of ten workers. However, Imperial management did not correct the underlying causes of the sugar dust problem at the Port Wentworth facility, where workers testified that spilled sugar was knee-deep in places on the floor, and sugar dust had coated equipment and other elevated surfaces.
The report marked one of many times that the CSB has recommended that the U.S. Department of Labor’s Occupational Safety and Health Administration adopt a broad industry rule to protect American workers from all sorts of combustible dust. As explained in my previous post, Obama’s OSHA puts protecting workers from dangers of combustible dust on back burner:
The CSB first called for an OSHA regulation on combustible dust after issuing a 2006 report that identified 281 dust fires and explosions that killed 119 workers and injured 718 others nationwide between 1980 and 2005. In a November 2011 report, board investigators noted 17 other deaths in dust incidents the agency is examining, including three in a December explosion that killed three at the AL Solutions Inc. metals recycling plant in New Cumberland, Hancock County, W.Va.
