Root Cause Analysis

BakerRisk performs third-party investigations of incidents using first a detailed investigation of the events to determine what happened, followed by a root cause analysis which determines the technical and human factors that contributed to why it happened.

BakerRisk uses a structured root cause analysis methodology involving timeline construction and identification of causal factors, followed by the use of a predefined cause tree.  A predefined cause tree is one of the main root cause analysis methodologies recommended by the Center for Chemical Process Safety (CCPS).  BakerRisk’s Cause Analysis Tree is a state-of-the-art predefined tree, which provides a systematic approach for analyzing and selecting relevant elements of the incident scenario.  It is a deductive approach, looking backwards in time to examine preceding occurrences (technical and human factors) necessary to produce the specified incident.  The root cause output from the Cause Analysis Tree Methodology is organized in terms of the elements of CCPS’s “Guidelines for Risk Based Process Safety.”  BakerRisk has performed, for example, root cause analyses on several pipeline incidents that were reviewed by the Pipeline and Hazardous Materials Safety Administration (PHMSA).
