Statement from CSB Chairman Moure-Eraso on the Four Year Anniversary of the Catastrophic Imperial Sugar Explosion – Chairman Continues to Encourage Industry to Support a Combustible Dust Standard and Applauds Success of Recommendations

February 6, 2012
                Tuesday, February 7, 2012 marks the fourth anniversary of the massive sugar dust explosion that killed 14 workers and injured 38 others at the Imperial Sugar Refinery in Port Wentworth, Georgia.  The loss of life continues to be mourned in the community.

CSB board members and investigation staff keep the memory of this tragedy close to us as we continue to advocate for changes in national workplace rules aimed at preventing such accidents in the future. We believe the safety recommendations that followed from our investigation of this accident will go far in saving lives. I am pleased to report that on this accident anniversary all but one of our recommendations have been successfully adopted by their recipients. 

Specifically, the CSB called on the Occupational Safety and Health Administration, OSHA, to “proceed expeditiously” on our 2006 recommendation that OSHA promulgate a new combustible dust standard for general industry.  We believe such a standard is necessary to reduce or eliminate hazards from fires and explosions from a wide variety of combustible powders and dust. 

I am disappointed that OSHA has not moved forward on this recommendation. Completing a comprehensive OSHA dust standard is the major piece of unfinished business from the Imperial Sugar tragedy.

The CSB’s report into the accident was issued at a public meeting in Savannah, Georgia, in September of 2009. It concluded that Imperial Sugar had inadequately designed and maintained dust collection and sugar handling equipment and that inadequate housekeeping practices allowed highly combustible sugar dust and granulated sugar to build up throughout the refinery’s packing buildings. 

 It is gratifying to be able to report that during 2011 the CSB designated Imperial Sugar’s responses to all five of our safety recommendations to the company as “Closed-Acceptable Action.”  Specifically, the CSB recommended that Imperial Sugar develop a corporate-wide comprehensive program to control combustible dust accumulation, develop training materials that address combustible dust hazards and train all employees and contractors, and improve its evacuation procedures.  We recommended Imperial Sugar comply with National Fire Protection Association’s (NFPA) recommended practices for preventing dust fires and explosions, and urged the company to conduct a comprehensive review of all of its manufacturing facilities’ adherence to NFPA standards.   

We recently received notice from Imperial Sugar’s insurer, Zurich Services Corporation that it is providing its risk engineers ongoing training in the hazards of combustible dusts, which we recommended. This will help ensure that hazards are recognized and dealt with during insurance inspections. Additionally a series of safety recommendations to AIB International, the American Bakers Association and the Risk and Insurance Management Society -- to develop combustible dust training and auditing materials -- also have all been given a status of “Closed-Acceptable Action.”   

“Closed-Acceptable Action” means that the recipients have effectively implemented the safety changes requested by the board, and I commend them for taking these important recommendations seriously.

The CSB recently reissued our call for a dust standard with our investigation into three flash fires that occurred in a series of accidents at the Hoeganaes Corporation iron powder processing plant in Gallatin, Tennessee, taking five lives.  Indeed, OSHA   lowered the CSB recommendation’s priority on its regulatory agenda in recent weeks.

I continue to advocate for a comprehensive combustible dust standard, and encourage industry’s support.  Preventing dust explosions is a necessary investment: prevention saves lives and massive property losses.   It is my view that a comprehensive standard will save lives and prevent future combustible dust fatalities. 

Closure of the CSB’s recommendations shows that important preventive actions have been taken as a result of the CSB’s investigation. I applaud the actions of the organizations that took the appropriate action to fulfill the CSB’s recommendations.

The CSB is an independent federal agency charged with investigating serious chemical accidents. The agency's board members are appointed by the president and confirmed by the Senate. CSB investigations look into all aspects of chemical accidents, including physical causes such as equipment failure as well as inadequacies in regulations, industry standards, and safety management systems.

The Board does not issue citations or fines but does make safety recommendations to plants, industry organizations, labor groups, and regulatory agencies such as OSHA and EPA. Visit our website,
