Along with the development of the world's industry and since the beginning of theindustrial revolution, the world is never be separated from the use of chemicals. Oneof the chemicals used is hydrogen chloride/hydrochloric acid which is the rawmaterial of plastic PVC, furniture cleaning materials, to produce gelatin, foodaddictive substances, and the leather tanning process, so the risk of HCL is very large.There is no exception for the tank material as the place to store materials. Therefore,it is very necessary need the level risk assessment in design phase HCl 33% storagetank againts tank material and financial consequences aspects if there is a leak at thetank.In this study, the analysis of the risk assessment used the Quantitative Risk AnalysisMethode API-RBI 581:2008. This study shows that the value of Probability ofFailure (PoF) obtained is 3909,24 and is on category 5 (1000 < Df-total ≤10000), ifthere is a hole in the wall of the tank its cost of consequence is US$ 8.670.000, oncategory D and at the high level risk. While the cost of consequence if there is a holeat the plate of bottom tank is US$ 21.500.000.000 and is on category E and at thehigh risk level.Keywords : Storage tank, Ammonia, dispersion, BREEZE Incident analyst, FaultTree Analysis
This thesis discussed the potential and risks of fire on workers in the offshore platform oil and gas production caused by hydrocarbons hazard by identifying those hazard. Hazard calculation was conducted in order to find out the specific location which has potential risk, then calculated individual risk per annum (IRPA) surveillance followed by the final results of the Potential Loss of Live (PLL). These results compared to criteria or standards and determine the position of workers was in ALARP condition or not. This research was a quantitative risk assessment with descriptive design. The results of this study gave recommendation to company for maintain programs and activities that always prevent fires even though the CB platform is within the acceptable region. Alert to the hazard of hydrocarbons, increased awareness of workers at workplace, checking and monitor hazards, and always follow working procedure.
All risk management activities always focus on activities to reduce or minimize risks. Many risk analysis methods are used when applying risk management in work-related activities Layer of Protection Analysis (LOPA) analysis is one of the semi-quantitative risk analysis methods in risk management aimed at reducing or reducing risk by formulating a protective layer that will be used to reduce the risk level. LOPA is determined by three main factors, namely: Scenario Determination, Initiating Event Selection, and Independent Protection Layer Selection. PT X and PT Y are one of the chemical process industries selected for their LOPA study. The background of the election of PT X and PT Y is because both companies have similar characteristics to the burning fuel terminal in Buncefield tragedy The results showed that the risk reduction of both companies was different, although the scenario and the Independent Layer Protection (IPL) involved were identical. This difference is because both companies have different rules of IPL treatment program. PT X has a more stringent treatment program regulation than PT Y. All programs aimed at maintaining customs will increase the risk reduction value by a factor of 10. Validation and ITPM (Inspection, Testing and Preventive Maintenance) is one of the steps that can be used to enlarge the Risk Reduction of LOPA study results.
WT16 Solvent storage tank has a potential fire risk because this tank contain flammable liquid solvent. Even though, there is no record that this case ever happens in Indonesia. But, fire risk assessment is the essential activities that need to do for chemical industry, petrochemical industry or any other industry that use hydrocarbon in their industrial activity. The method used for this paper is descriptive method with secondary data about the storage tank. This paper use qualitative risk assessment result that fire risks for WT16 the storage tank is high. Then based on the calculation of the ALOHA software in getting the results of the thermal radiation in tank number 3 have 71 meters with 10 Kw/m2 intensity of radiation, 97 meters with 5 Kw/m2 intensity of radiation, 147 meter with Kw/m2 intensity of radiation and for tank number 2 have 68 meters with 10 Kw/m2 intensity of radiation, 94 meters with 5 Kw/m2 intensity of radiation, 142 meters with 2 Kw/m2 intensity of radiation. Then, a safe distance by calculating using the acceptable separation distance calculator results obtained within safe for humans 179, 16 meters and 35.38 meters for buildings for tank number 3 and for the tank number 2 the safe distance is at 128, 60 meters for humans and 24, 48 feet for the building.
Proses pengolahan gas di Plant SBN adalah sebuah pabrik yang mempunyai bahaya cukup tinggi.

Gas refinery process at SBN Plant is a plant which contains hazardous material/fluid during its process. Natural gas composition as hydrocarbon contains impurities such as HQO, CO2, H23 and other particles, which may cause equipment damage (including corrosion, thinning or cracking). A product from gas refinery is gas, condensate and produce water which they have difference hazards characteristic. However if there is gas or condensate leaking or exposed to employees or environment, it can lead a worst event. This research is to perform risk assessment using descriptive analysis approach by calculating and analyzing the probability of failure (POF) and consequence of failure (COF) at 6 (six) storage tanks at SBN Plant by using API 581 Standard as qualitative risk assessment approach with checklist table. Results suggested that probability of failure (POF) and consequence of failure (COF) factors are as follows: condensate tanks 235-T-101A and 235-T-101B have risk ranking "high"; condensate tank 235-T-201 has risk ranking "medium-high" (significant risk); diesel fuel tank 247-T-101, produce water tank 258-T-101 and 258-T-201 have risk ranking "low". Damage Factor and Inspection Factor are dominant contributing factors in probability of failure calculation and Chemical Factor, Quantity Factor, Auto Ignition Factor, Pressure Factor, Credit Factor (Safety Protection) are dominant contributing factors for consequences of failure calculation for 6 (six) storage tanks during risk assessment process.
Industrial disasters claim thousands of lives every year around the world. Most are caused by poor construction or design of facilities or large fires or explosions that engulf buildings. In addition to poor design facility, emergencies can occur as a result of a Process safety event (PSE) which involves the release/loss of containment of hazardous materials which can result in large-scale health and environmental consequences. At this time PT. J is at the design stage of the petrochemical industry. The company will process chemicals in large quantities so that the company has a high hazard and the risk of causing an emergency event, therefore PT. J requires an emergency management system that can handle any potential emergency events that might arise and impact the company at the operational stage. The purpose of this study was to analyze emergency management planning at the design stage of the petrochemical industry at PT. J, which consists of planning before an emergency occurs, when an emergency occurs and after an emergency occurs. This research is an analytic descriptive research, using a qualitative study design. Primary data collection was carried out through field survey and conduct Focus Group Discussion (FGD) using the Emergency Management Assessment Checklist for Design Stage, which has been modified from the NFPA 1600 edition 2019. Secondary data was collected through document review. Based on the research results shows that PT. J has not implemented a comprehensive emergency management life cycle. At the stage before an emergency occurred, the company did not yet have planning for competency and training, drills and trials. At the stage when an emergency occurs, it is known that the company doesn’t have procedures for testing protocols for warning, notification, and communication during an emergency. In addition, at the stage after an emergency occurs, the company does not yet have a continuity and recovery plan that includes rehabilitation and reconstruction. The company has carried out and has several plans for mitigation, preparedness and emergency response. Companies are advised to develop existing plans and create new plans to maximize emergency management planning at the design stage to deal with emergency events in the petrochemical industry at the operational stage of PT. J.
