An Analysis of CSB Investigation Reports Concerning the Hierarchy of Controls

摘要

Sixty-three reports,studies,and bulletins resulting from process incident investigations conducted by the U.S.Chemical Safety Board (CSB) have been analyzed for evidence of examples related to inherent safety,passive and active engineered safety,and procedural safety.These risk reduction measures,which collectively form the hierarchy of safety controls,were also analyzed for their contribution to both incident prevention and consequence mitigation.
