Consequence analyses of hazardous chemical releases, as a part risk assessment process, are very important for emergency response planning. The outcomes the release chemicals influenced by degree turbulence in atmosphere. In this study, consequence 1,3-butadiene releases pipeline petrochemical zone due attention high flammability effects selected modeling using ALOHA software. Furthermore, threshold levels heat radiation and probability death were calculated probit equation. Finally,...
Fire and explosion are the most prevalent accidents in chemical process industries. Hence, identification of hazard factors methods controlling these two major very important In this paper, fire hazards some units at a combined cycle power plant have been estimated using Dow index. The results study show that methane fueled turbine has highest value index which is 321, unit with gas oil storage site values 147.5 35.5 respectively. loss control credit factor for was 0.36 Actual Maximum...
1,3-Butadiene is a chemical that extremely flammable and toxic. Therefore, in this study, airborne quantity of 1, 3-butadiene was determined by the exposure index (CEI) local meteorological data were used for consequence analyzing. Furthermore, heavy gas model modeling 1,3-butadiene vapor cloud dispersion using Areal Locations Hazardous Atmospheres (ALOHA) software, threat zone different stability classes determined.
The accidents caused by the domino effect in industries are highly harmful. This study aims to analyze occurrence probability of with respect possible explosion and fire scenarios chemical tanks. Using results obtained previous studies, reviewing past accidents, according equipment damage models, threshold values were used for extraction process inherent safety distances as a criterion prevent accidents. According primary experimental equations, escalation vector was determined different...
Introduction: One of the ways to produce electricity in power plants is use gas turbines and generators. Due methane as fuel burners high rotation speed, this equipment has a DOW index level, therefore, if hazardous conditions turbine are not controlled by safety instrumented system process directed safe state, Catastrophic events will occur such fire explosion damage property people well interruption generation happen long term, so instrumentation systems can be considered “critical...
Safety training programs play an effective role in reducing diseases and accidents during working. The purpose of this study was comprehensive safety planning for the gas pipeline construction industry, investigation its effectiveness a pilot project. For purpose, interventional research (before after), risk-based needs assessment performed. Afterwards, program developed implemented based on assessment. After 6 months implementing program, assessed using three questionnaires 19 checklists....
Many accidents always happen in the electricity distribution sector, which requires use of control strategies this field. Therefore, study presented a risk assessment method based on fuzzy Bayesian network (FBN) and William Fine low-voltage power systems to reduce structural uncertainties studies examined reliability these achieve proper performance emergencies. The first step is develop fault tree (FT) event (ET) bow tie (BT) format. In study, theory expert judgment were used qualitatively...
The aim of this study was to determine the root causes accidents and responsibility rates parties involved in those accidents. For purpose, 20 important an automotive company were selected causes, respective determined by 10 experts based on dividing into 11 Tripod Beta basic risk factors using occupational accident tree analysis (OATA) component (OACA) techniques. results revealed that among defects management system, organizational system's had greatest impact occurrence By modifying about...
The accident of falling from a height is high among construction workers. Construction workers do not use harnesses. Thus, the present study was conducted to identify factors affecting non-use harnesses in Tehran, Iran.In this by interviewing professors and order harness. Factors influencing safety were identified workers' point view. obtained data classified coded using MAXQDA 10 software. After that, most essential, effective powerful degree intersectionality social network...
