Fuzzy-based Prioritization of Health, Safety, and Environmental Risks: The Case of a Large Gas Refinery
Get PDFThe main objective of this study was to develop a fuzzy–based framework for the prioritization of health, safety and environment related risks posed against employees, working conditions, and process equipment in large gas refineries. The First Refinery at Pars Special Economic Energy Zone in South of Iran was taken as a case study. For this purpose, health, safety and environment related risks were determined based on the three criteria of impact severity, occurrence probability, and detect-ability using a questionnaire of 33 identified failures. The values obtained were processed by a so-called ‘contribution coefficient’. The results were then subjected to fuzzification and fuzzy rules were defined to calculate the risk level indices as the model outputs, which was then employed to facilitate the management decision-making process by prioritizing the management options. The prioritization values were then classified in six categories in the order of risk severity. Results revealed that failure in a combustion furnace had the highest rank while failure in the slug catcher ranked the lowest among the risk sources. It was also found that about 0.4% of the identified risks prioritized as “intolerable”, 79% as “major”, 20% as “tolerable”, and 0.7% as “minor”. Thus, most of the risks (more than 79%) associated with the refinery has the potential of significant risks. The results indicated that the risk of the pollutant emissions from the combustion furnaces is the highest. Exposures to harmful physical, chemical, psychological, and ergonomic substances are the other risks, respectively

Evaluation and Management of Human Errors in Critical Processes of Hospital Using the Extended CREAM Technique
Get PDFMedical errors result in serious and often-preventable problems for patients. Human errors can be used as an opportunity for learning as well as a key factor for patients’ safety improvement and quality of patients' surveillance in hospitals. The aim of the present study was to identify and evaluate human errors to help reduce risks among personnel who render health services during critical hospital processes. This cross-sectional study was done in the Besat hospital in Hamedan in 2016. At first, the critical processes were selected via given scores in Delphi method and by multiplying the scores of each of the five criteria including the severity of the consequences caused by error incidence, probability of error, capability of the error detection, task repeatability and type of hospital ward with each other. Determining the risk numbers of each process, three ones were chosen with the largest scores. At the end, the selected processes were analyzed by the method of extended CREAM. The results showed that the highest CFP is associated with the CPR process, particularly in the sub-stage of command of starting CPR by anesthesiologists (0.0891), the one in the giving medicine process is in the sub-stage of calculating of medicine dozes and determining prescription methods (0.0796) and also the one in the tracheal intubation process is in the sub-stages of pulmonary and respiratory monitoring of patients and observing the vocal cords and larynx of patients (0.0350). Regarding the critical consequences of human errors in the selected processes, reviewing the qualities of roles and responsibilities of each of the medical group members and providing specialized introduction for hospital processes seem necessary

Monitoring of THMs Concentration in Isfahan Water Distribution System and Zoning by GIS, a Case Study in the Center of Iran
Get PDFTrihalomethanes (THMs) formation in treated water is a consequence of a reaction between the chlorine used for water disinfection and some natural organic matters. The objectives of the present study were monitoring of THMs concentration in Isfahan (A metropolis city in center of Iran) water distribution network (IWDN), evaluation factors that affect the THMs formation potential and identification of critical points by using geographical information system (GIS). The study was performed in summer months of 2014. For sampling point's selection, city divided into 30 zones and water quality parameters such as pH, Electric Conductivity (EC), residual Chlorine, Total Organic Carbon (TOC) and THMs of IWDN measured. Multi regression analysis was used to estimate the correlation between THMs formation and these variables. While the statistical analysis with Spearman non-parametric correlation coefficients showed a positive correlation between distance from treatment plant and THMs concentration(r=0.45, P =0.01) and negative strong correlation(r=-0.95, p>0.001) between THMs and TOC concentrations, there was no strong significant relationship between THMs formation in IWDN and some variables including pH, temperature and residual Chlorine.
The results reveal that the average value of the THMs at sampling points for summer attained 42.56 ppb which was lower than the EPA and WHO standards. It is recommended that the distance from the treatment plant was used as an effective parameter for estimation of THMs formation potential
A Study of The Relationship Between The Components of The Five-Factor Model of Personality and The Occurrence of Occupational Accidents in Industry Workers
Get PDFAccidents are among the most important problems of both the developed and the developing countries. Individual factors and personality traits are the primary causes of human errors and contribute to accidents. The present study aims to investigate the relationship between the components of the five-factor model of personality and the occurrence of occupational accidents in industrial workers.
The independent T-test indicated that there is a meaningful relationship between the personality traits and accident proneness. In the two groups of industry workers injured in occupational accidents and industry workers without any occupational accidents, there is a significant relationship between personality traits, neuroticism (p=0.001), openness to experience (p=0.001), extraversion (p=0.024) and conscientiousness (p=0.021). Nonetheless, concerning the personality trait of agreeableness (p = 0.09), the group of workers with accidents did not differ significantly from the workers without any accidents.
The results showed that there is a direct and significant relationship between accident proneness and the personality traits of neuroticism and openness to experience. Furthermore, there is a meaningful but inverse correlation between accident proneness and the personality traits of extraversion and conscientiousness, while there was no relationship between accident proneness and the personality trait of agreeableness
