Background; Prevention of accidents—a crucial requirement in oil industries—involves hazard recognition, risk assessment, and corrective actions. The purpose of this study was to compare the ETBA and HAZOP techniques for risk assessment in a gasoline refinery unit.
Methods; In this case study, data were collected using process flow diagram, walking–talking through method, piping and instrumentation diagram, and direct observations. Worksheets for both techniques were filled on the basis of the risk assessment matrix MIL-STD-882E.
Results; The HAZOP method identified 44 deviations attributable to 118 causes. In addition, 11.37% of the identified hazards were associated with unacceptable risk, and 36.36%, with unfavorable risk. The ETBA method detected 10 groups of energy (24 subgroups); 33 hazards were detected, 10.62% of which were associated with unacceptable risk.
Conclusion; HAZOP proved to be the more powerful technique for the prediction and identification of hazards. However, ETBA detected certain hazards that were not identifiable using HAZOP. Therefore, a combination of these two methods is desirable for the assessment of hazard risk in process industries.

Background: Work-related musculoskeletal disorders (WMSDs) may involve all parts of the body, and have been a worldwide problem. Employed women are two to five times more likely to report such problems, and assembly lines suspected to induce more WMSDs because of high rate of repetitive motions.
Methods: The aim of this study to determine the prevalence of WMSDs in women workers of an automobile manufacturing assembly line. In this cross-sectional survey, 50 women workers in an automobile manufacturing assembly line were studied. Data was collected based on Nordic questionnaire. The statistical analysis was performed by the SPSS 11 software.
Results: The MSDs prevalence rate was 98%. The most reported complaint was related to the back (68%) and there was a significant relationship between prevalence and pain severity with age and working years. Moreover, the duration of feeling pain per day, and pain severity had a significant relationship with the capability of the person to continue working.
Conclusion: Workstations ergonomically improvement and employing men instead of women would be effective to reduce the problems.

Background: Musculoskeletal disorders (MSDs) are among the most prevalent pains which could be ignited via material handling. Backpack wearers are among those who may carry heavy loads. Since MSDs mainly originate in school-aged children, students (as the largest group of backpack wearers) are considered more important. The purpose of this study is to design a backpack based on minimization of shearing force.
Methods: At first the relevant patents were investigated at national and international levels. Then the appropriate ones selected for optimizing. The main selection criterion was based on reduction of pressure on body. As an extra function we used a generator to produce electricity. The criterion for electricity generator selection was: 1) small dimension, 2) low weight, and 3) safe voltage.
Results: A suspending system used to eliminate shearing forces. Since a wearing backpack student is under the shearing force caused by walking, a spring system was used as a reducing device for shearing force. Physical spring calculation revealed that springs with stiffness coefficient equal to 588 was appropriate.
Conclusion: In comparison with existing designs, suggested backpack design can reduce forces on upper limb during handling the backpack

Background: Rapid pace of the construction projects have led to safety negligence on the part of the contractors causing higher numbers of accidents in construction industry. Thus, over 2200 legal provisions have been established for the prevention of accidents on construction sites. Not only contractors are unable to implement all provisions, but also it is hard for regulatory bodies to implement all rules, but they are also hard to remember and attend to by regulatory forces. Therefore, identifying the set of codes with the highest effect on reducing accidents would be most beneficial. The aim of this study was to determine the most effective legal provisions in reducing accidents on construction sites in Zanjan city.

Methods: In this study, 378 work-related accidents in construction sites in Zanjan city, already registered in the Labor Inspection Authority, were investigated .Then the codes that had not been respected in the construction industry accidents were identified. Effective codes were determined based on their frequency on Pareto chart.

Results: Results indicated that out of 2200 legal matters, only 164 were broken in the accidents.

Conclusion: Application of Pareto chart could raise safety professionals' awareness of the specific broken codes in accidents, thus draw higher attention to the codes.

Background: Occupational incidents still account for a high percentage of causes of death and disability. A study was designed to determine the relationship between employee safe behavior and safety culture.
Methods: In this analytical study, all employees of an industrial livestock units of Tehran participated (n = 200). The data on the employee behavior was evaluated using the safety sampling technique based on the ANSI Dangerous Acts List (Modified Form). A standard questionnaire was used to assess the safety culture. Data were analyzed by the SPSS software, at the significance level of 0.05.
Results: The mean safety score of people (138) was acceptable. The rate of unsafe behaviors was 35%. The most unsafe behaviors were due to improper manual handling (83%). A reverse correlation between unsafe behavior and safety culture score (P value = 0.001) was seen.
Conclusion: The results of this study indicate that there is a significant negative reciprocal relationship between safety culture and unsafe behavior, that is, with the increase in the safety culture, the rate of unsafe behavior decreases. As a result, by promoting the level of safety culture, the rate of unsafe behavior can be reduced.

Background: Economic pressures are important factors contributing to accidents. Despite the importance of economic factors in the safety of taxi drivers, a few literatures have referred to these factor.
Methods: This research was a phenomenology study. The purposive sampling was used, so, 18 taxi drivers with the average 43.05 ± 10.22 years old participated in the study of whom, 12 took part in individual in-depth interviews (IDIs) and 6 participated in a focus group discussion (FGD). The Bengtson’s method (2016) was adopted to analyze qualitative data using content analysis.
Results: Two themes interlacing the impact of taxi drivers’ Economic pressure on their safety were identified. The themes referred to taxi drivers’ occupational expenses and livelihood concerns. Each of the themes were consisted of two categories, namely competition for passenger, taxi-keeping expenses and stability, adequacy of income, and undesirable household economic conditions, respectively.
Conclusion: This study showed the significant impact of economic pressure on the safety of taxi drivers as participants repeatedly reported unsafe driving behaviors in order to increase income. They also stated that issues such as unemployment and inflation caused many people to enter this occupation which led to dangerous competition over passengers and subsequent aberrant driving behaviors.

Background: The construction of metro lines is a high-risk project. Using a budget-based model for the safety units of metro construction projects can help safety managers to spend optimal budget allocation. The purpose of this study was to plan a budget model based on safety unit performance in an under construction metro station for better budget allocation using robust optimization.
Methods: To design this model, budget dimensions were identified by the experts and based on causes and costs of accidents in the past year. Then, constraints of metro workshops were considered. The next step was involved in determining the importance of each dimension. Finally, the budgeting model was designed using Gurobi software. In order to prove the proposed budgeting model, as a case study, the model was implemented in one of the metro workshops.
Results: Considering existing constraints, the model revealed that the budget should be at least 4.370.478.000 rials. Surprisingly, the predicted budget amount was less than the expended amount in the safety unit of the project. However, budget allocation to dimensions was dramatically different.
Conclusion: The results showed that the robust optimization budgeting was functionally and economically optimal. Moreover, there is a need for logical budget distribution.
