We have had major chemical-related incidents in both California and Washington in the past week. These will be investigated by the U.S. Chemical Safety and Hazard Investigation Board . Like the National Transportation Safety Board, the USCSHIB has an admirable record of making our nation safer.  The USCHIB has already announced it has opened an investigation into the Washington paper mill explosion which killed one person. The explosion occurred yesterday and the investigative team is arriving this morning.  Yet, when a flood or tornado or hurricane causes triple digit fatalities in the United States there is no organized system of expert review to learn what went wrong (if anything) and how we (meteorologists, emergency managers, medical teams, etc.) can improve our responses going forward.  A succinct outline for a National Disaster Review Board is here .
