Each case history offers valuable insights into the importance of having a systematic method for the management of change (MOC). An MOC methodology should be applied to operational deviations and variances, as well as to preplanned changes—such as those involving technology, processes, and equipment.

CSB Safety Bulletins offer advisory information on good practices for managing chemical process hazards. Actual CSB case histories provide supporting information. Safety Bulletins differ from CSB Investigation Reports in that they do not comprehensively review all the causes of an incident.
