Investigation And Analysis Technique Fault Tree Analysis

Investigation and Analysis Technique The following report examines a three types of investigation techniques – Fault Tree Analysis, Event Tree Analysis and Failure Mode and Effect Analysis. The methodology of the report is based on a research on the developmental history and procedural methodology of these three analytical techniques. This research paper will identify the strength and weaknesses of all three techniques and an opinion on which method is preferred. In the last section of the report, I will examine an accident scenario and conduct an investigation using the Fault Tree Analysis method. Fault Tree Analysis (FTA) There are multiple causes of an accident or a loss-making event. The Fault Tree Analysis is one of the many analytical techniques that is used for tracing the series of events that could contribute to an accident (NEBOSH, 2010). Who or What Company Developed The FTA and Why The Fault Tree Analysis method was developed in 1962 at Bell Telephone Laboratories by H.A. Watson, under a U.S. Air Force Ballistics Systems Division contract to evaluate the system safety and reliability of the launch control system for the Minuteman Intercontinental Ballistic Missile (ICBM) (NIOSH, 2010). It was later adopted and applied by the Boeing Company as a systematic safety analysis method to promote the safety of highly technical complex systems and the nuclear industry to improve the safety and reliability of nuclear reactors (NIOSH, 2010).

As a deductive approach, FTA starts with an undesired event, such as failure of a main engine, and then determines (deduces) its causes using a systematic, backward-stepping process. In determining the causes, a fault tree (FT) is constructed as a logical illustration of the events and their relationships that are necessary and sufficient to result in the undesired event, or top event. The symbols used in a FT indicateRead MoreHazard And Risk Management : Premier Inn2762 Words   |  12 Pagescash registers.

Risk Assessment It consists of the identification of hazards and the analysis and evaluation of risks associated with exposure to those hazards. Quality risk assessments initiate with a well-defined problem report or risk question. Once the risk in question is well defined, a suitable risk management tool and the types ofRead MoreThe Safety And Health Administration1439 Words   |  6 Pagessafe productive work environment at _________________, this chemical and hazardous materials health and safety training program will introduce.

Abstract This report summarises the different levels of Probabilistic Safety Analysis (PSA) involved in assessing risks and consequences from nuclear power plants. These risks can be measured in a variety of ways including: estimated frequencies of core damage accidents from both internally and externally initiated events, the likelihood of a containment structures encompassing radionuclides under accident loadings; the potentialRead MoreHow Relevant Is Freud Today1559 Words   |  7 PagesSigmund Freud was arguably one of the most influential psychologists in the investigation of personality, and his work can still, to some extent, be considered relevant today. His methods allowed for the first time the investigation of phenomena that were previously difficult to tackle, such as dreams and sexual desires. â€Å"Yes and No† is a justified reply to the question of whether Freud is relevant today in that his ideas on personality were the first to investigate the role of childhood trauma ,Read MorePaper on Work Place Safety10014 Words   |  41 PagesON: WORKPLACE SAFETY SUMMARY In this paper, workplace safety is discussed. Analysis of historical data on workplace accidents were used to establish the need and importance of workplace safety. Relationship between Safety and Reliability Engineering was established to show how reliability engineering techniques and methods can be used to evaluate, identify risk prone activities and machines, with a view of reducing to the bear minimum the faultyRead MoreSupporting Interactive System Testing With Interaction Sequences Essay6586 Words   |  27 Pagesincorrect behaviour in the system. By removing these robustness testing is performed, which simply nds crashes in the system. While this can be useful to nd existing faults in the system, it does not comprehensively test the system. Therefore, it can be unclear as to why the crash occurred in the rst place, generating more work to nd the fault and increasing the tester s work load. Due to the increased time and cost of this eect it is a common deterrent for use of testing methods. The sequences in existing
