The present study aimed to analyze health, safety and environmental (HSE) risks relating to construction projects based on the project management body of knowledge (PMBOK) and sustainability approach. This study was conducted with the participation of 30 experts, using the semi-quantitative risk assessment technique, in nine areas of the project management’s body of knowledge, based on the fuzzy analytic hierarchy process. Risk, in this study, was estimated using a two-dimensional matrix of incident probability and severity, each of which has four sub-parameters. The HSE risks pertaining to each of the nine areas of PMBOK were identified. After that, the two dimensions of risk, including incident probability and severity, were measured. Thirty-seven risk sources associated with nine areas of the PMBOK were identified. Risk analysis revealed that 2...

The amount of biogas production in treatment plants for energy generation has increased in recent years. This study aimed to model the consequence of biogas release in a large urban treatment plant.Materials and methods. The present study was conducted to model biogas storage tanks' consequences in one of the large urban treatment plants in Iran. Due to the potential for this substance's harmfulness, all three consequences of toxic release, fire, and the explosion were evaluated. The scenarios were evaluated in the worst-case situation. All modeling steps were performed using PHAST 7.2.Results. In the case of catastrophic rupture of the reservoir in the summer, distances of 3788.94, 128.86, and 91.72 meters from the reservoir in the direction of the wind will be placed in the range of 100, 500 and 1000 ppm of biogas, respectively. The study of pressure values due to explosion in the catastrophic rupture scenario revealed that distances of 57.19, 14.70, and 115.84 meters from the biogas reservoir were in the range of 0.02, 0.13, and 0.2 bar pressure increase, respectively.Conclusion. Due to the treatment plant's location in a dense urban area, biogas' dispersion could lead to many people's exposure to high-risk areas. Therefore, taking control measures comparable with the consequence modeling output can be a practical step towards reducing the vulnerability against such incidents.

This study aimed to develop a Bayesian network (BN) model for managing and improving safety behavior. MATERIALS AND METHODS This study was carried out in the chemical industries in Iran. The data were gathered by a questionnaire consisting of thirteen variables including organization safety priority, systems design, safety communication, safety education, work strategy, human-system interaction, mental workload, environmental distractions, work pressure, fatigue, sleepiness, safety knowledge, and locus of control. The BN structure was created using the Fuzzy decision-making trial, evaluation laboratory method, and expert opinions. Belief updating was used to find out variables with the strongest effect on safety behavior. RESULTS Locus of control, organization safety priority, and safety knowledge were the best predictors of safety behavior. Moreover, it was found that improving organization safety priority and safety knowledge is the best intervention strategy to improve safety behavior significantly. CONCLUSIONS BN is a powerful tool that can model causal relationships among variables. Improving organization safety priority and safety knowledge can lead to the maximum, possible level of safety behavior.

This questionnaire-based study was carried out on Iranian workers to investigate the direct and indirect effects of work pressure, mental workload, human-systems interaction and environmental distractions on three types of human error (i.e. slips, lapses and mistake). The results of path analysis showed that based on model fit indexes, the model is appropriately fit (χ2/df = 3, CFI = 099, TLI = 0.99 RMSEA = 026). It was also observed that the effects of four independent variables on all three types of human error are indirect and mediated by situation awareness. Consequently, it is confirmed that situation awareness plays a key role in the occurrence of human error and is a sharp-end causal factor for human error in industrial workplaces.

Job stress is related to the low quality of life, job burnout, increasing the risk of accidents and work–related injuries and cause job change and early retirement of employees. This study aimed to evaluate employees' job stress in an industry as well as to assess its relationship by personal (age, education, chronic disease, taking medication, and smoking) and job (type of occupation, work experience, type of employment, working hours per day, second jobs and accident) variables. This descriptive study was conducted in 2013 on all 149 employees of a manufacturing company. Data collection was done with HSE's Management Standards Indicator Tool. Information was gathered in Semi–supervised self–reported manner. Independent–sample T test, one–way ANOVA, and linear regression were used for data analysis. All statistical analysis performed in SPSS software version 16. The mean of participant's age and work experience was 39.8 and 15.43 years, respectively. Mean of job stress score was 3.59 ±0.45 and was in no stress range. Among the studied variables, type of employment, the permanent taking of medication and accident have a significant relationship with job stress (P<0.05). But, other variables did not have a significant relationship with job stress. Injured personnel and drug users have higher stress levels than others that need to be considered in these cases. Also, job stress in employees and contract staffs is more than conventional workers. Thus, more detailed examinations are needed for those employees.
