Risk Analysis and its Mitigation Strategies for Chlorine Handling in Chemical Process Industry by Process Safety Management

The applications of chlorine have been widely used in many industrial products, such as bleaching agents, synthetic rubbers, plastics, disinfectants, iron chlorides, fire refractory materials, insecticides and anti-freeze, etc. The consequence analysis used three different methods to analyze the worst-case scenarios and alternative release case scenarios to study the effects on influencing zone by different active and passive mitigation systems, such as confined space, scrubbers, water-spray, etc and apply an integrated modeling system to estimate fatalities from intentional release of 900 kg of chlorine from a chlorine tonner in a chemical of industrial area. Risk identification is carried for identification of undesirable events that can leads to a risk, the analysis of Risk mechanism by which this undesirable event could occur and usually the estimation of extent, magnitude and likelihood of harmful effects. The objective of Risk Identification is to identify the potential of hazards which are available during chlorine handling in process chemical industry.
