Risk Management of Chlorine Gas Release from Chlorine Gas Storage Tanks Using FMEA Method

Chlorine is a toxic and oxidizing gas used to purify drinking water in Iran. There has been no research on the effects of the gas or the explosion of the tanks, which could cause irreparable damage to people and the surrounding area. No such study has been carried out in the city of Abadan. To this end, Areal Locations of Hazardous Atmospheres (ALOHA) software, a computer program that helps professionals understand what will happen during a hazardous release, such as a chemical or fire, allows them to make plans to keep people safe. Thus, it was used to assess the magnitude of the gas release, the various risk zones, and the population at risk. In the event of damage to the ۱-inch outlet valve of the tank, the gas release could be lethal up to a radius of ۲ km, could be effective up to a radius of ۶.۲ km, and could be felt up to ۱۰ km away. Due to the probability of occurrence and the location of the station in the wind direction, gas could reach many residents within a ۵ km radius of the station. Therefore, as indicated by the results of the failure mode and effects analysis (FMEA) model evaluation, the implementation of preventive measures is strongly recommended in order to avoid gas release in settling tanks.
