Reviewing Tools to Prevent Accidents by Investigation of Human Factor Dynamic Networks

Abstract

A network of serial, parallel and cross-related factors transfers the hazard energy until the accident occurs. This paper aims to discuss the failure of barriers initially built to prevent the accident, the factors that need to be included in the analysis to review human elements and their safeguards, and the need for critical judgment for resilient and accident-alert safe behavior. It is intended to study past accidents and establish relationships between these factors, antecedents and consequences. The availability of a competent team to interpret the chain of events that can lead to the accident is crucial in ending the hazardous energy migration. It is expected to measure the ability to increase or decrease the hazardous energy considering ship collision with oil leak. Analysis of human elements in the project before and after the accident layer factors may suggest changes in safeguards or recommendation of new barriers to the accident.
