Consequence and Effect Analysis

The consequence and effect analysis addresses to analyze the major accident like a toxic product release, explosion, jet fire, fire ball and BLEVE. Those accident scenarios are first identified and assessed by qualitative risk analysis methods and then quantitative methods are applied to have a more precise assessment.

Indeed, the main objective of consequence and effect analysis is to define the vulnerable are which employees are exposed to such major accident and also define the effect of such accident in employees’ health. In order to perform its required to collect some information from the accident scenario like weather conditions, type of product and their physical and chemical characteristic, the volume and storage conditions. In most of the cases due complexity, such analysis is performed by different software packages. In order to support decisions about risk mitigation to reduce the consequence of major accident the individual risk and societal risk criterion is defined as a baseline to such mitigation action. In addition, based on the consequence and effect analysis, it is also possible to take decision about facilities, location into industrial area as well as location of industrial facilities surrounded by population.
