Hazard Analysis Using HAZOP: A Case Study

  • Morris Chudleigh
Conference paper

Abstract

There is an increasing use of computing in safety related applications and ensuring that such systems are conceived, designed and produced with appropriate attention to safety is not easy. The process of identifying undesirable events and their consequences is known as hazard analysis. Carrying out a hazard analysis at varying stages during the development process is now being mandated in emerging standards produced by the International Electrotechnical Commission (IEC) [1] and the U.K. Ministry of Defence [2].
