Prepared for Presentation at 8th Global Congress on Process Safety Houston, TX April 1-4, 2012 Keywords: investigation, near miss, accident, incident, root cause, RCA ABSTRACT The need for effective root cause analysis is finally gaining the spotlight in the chemical process industry.

The definition of a near miss (a potentially damaging sequence of events and conditions, but without harm) can be vague and varies from site to site.
