A grim message from Chairperson Vanessa Allen Sutherland of the US Chemical Safety Board reads-

“The U.S. Chemical Safety Board (CSB) is disappointed to see the President’s budget proposal to eliminate the agency.  The CSB is an independent agency whose sole mission is to investigate accidents in the chemical industry and to make recommendations to prevent future accidents and improve safety.  For over 20 years, the CSB has conducted hundreds of investigations of high consequence chemical incidents, such as the Deepwater Horizon and West Fertilizer disasters.  Our investigations and recommendations have had an enormous effect on improving public safety.   Our recommendations have resulted in banned natural gas blows in Connecticut, an improved fire code in New York City, and increased public safety at oil and gas sites across the State of Mississippi.  The CSB has been able to accomplish all of this with a small and limited budget.  The American public is safer today as a result of the work of the dedicated and professional staff of the CSB.  As this process moves forward, we hope that the important mission of this agency will be preserved. ”     -posted 3/20/17

I want to voice my support generally for this elite group of accident investigators. As a chemical safety professional myself I am disappointed to see the CSB regarded low enough by the President’s budget writers to warrant being in the proposal for elimination. The job of the CSB is to investigate the cause(s) of chemical, petrochemical, or other facilities that handle materials having the potential to produce serious accidents. Having done accident investigations myself, albeit at much reduced scale from a petrochemical refinery, I appreciate what a difficult job this is and the great value of the disseminating findings to the industry.

The value of any given CSB report is the story of how an accident is initiated, how it propagates, and how it may couple with diverse systems. As a crucial part of the report is a detailed dissection of the relevant operational systems and human/machine interfaces and how they may have coupled to the event. It is educational and very useful for the safety community to learn how unfamiliar failure modes initiate and how knock-on effects may steer the accident in directions that are difficult to predict.

Planning for process safety involves input from the fields of chemistry, engineering and operations. Importantly, it requires imagination because planning safe operations is about predicting the future. Shutting down CSB investigations will deprive the engineering and safety community of a valuable resource detailing subtle or non-obvious ways in which complex systems can fail.

Recall the Apollo 1 fire or the Challenger explosion and how inquiry into those events lead to better appreciation of failure modes and the layers of protection that can be put in place to prevent the failure. If this kind of investigation is kept confidential, the advance of safe system design will stagnate.
