Also note the following temperatures of interest to process safety incident investigation teams (Perry and (ireen, 1997 NFPA 422M NFPA 1997 and Avallone and Baumeister, 1996). 

This group must be familiar with the concepts, policies, extent of commitment from upper-level management, and specific assignments of responsibility associated with process safety incident investigation.

Johnson s interpretation of MES concepts is known as Events Causal Factor Charting (E CF), or Causal Factor Charting for short, and has been adopted as one of the building blocks of several methodologies for process safety incident investigation. 

Events Causal Eactor Charting (E CE) (5) was adopted by the developers of MORT to identify and document the sequence of events leading to an incident. A number of proprietary process safety incident investigation methodologies, such as SOURCE ) and TapRooT C) include E CF as one of their building blocks.
