Chlorine is a toxic and oxidising gas used in Iran to purify drinking water. There has been no research into the effects of the gas or the explosion of the tank, which could cause irreparable damage to people and the surrounding area. No such research has been carried out in the city of Abadan. To this end, Aloha software (Aloha software is a special computer program that helps professionals understand what will happen in the event of a hazardous release, such as a chemical or fire. This helps them make plans to keep people safe.) Was used to assess the magnitude of the release, the various risk zones and the population at risk. The research shows that in the event of damage to the 1-inch outlet valve of the tank, the gas release could be felt up to a radius of 2 km, 6.2 km and 10 km. Due to the probability of occurrence and the location of the station in the wind direction, it is possible to reach a large number of residents within a 5 km radius of the station. Therefore, based on the FMEA model evaluation, the work prior to the chlorine gas meeting was prioritized to prevent the release of chlorine in the event of the tank settling.

Every day’s large amount of gas is consumed which is transported through pipelines. Due to irreparable consequences of gas related accident and their heavy financial losses; therefore, the safety of pipeline is one of the priorities of gas companies, government and consumers. Hazard is part of every human endeavor, so hazard identification and risk management is very important. As some of event may not be exactly predictable, the study of risk is very important. The risk management is a determinative step of the health, safety and environmental management system (HSEMS). In this study performance of Hazard and operability (HAZOP) method for asses of hazards and risks, for all process, that present in Kermanshah Province Gas Company was evaluated. There are different risk analysis techniques. As the HAZOP is Process Hazard Analysis that not only identifies system hazards, but also determines their probability of occurrence by the effects of any deviations from design conditions and it gives us the accurate results, it’s used for risk assessment in this project. This research was conducted by a team of 3 experts and identified the process hazards by means of quid words. At the end of this study in Kermanshah Province Gas Company’s about 282 risks were identified and only 03 risk is unacceptable e and 111 are Conditional that must be eliminated without delay , the others are acceptable that the risk must be eliminated but it is not an emergency
