Objectives: Indices are extensively used for ranking various units of a chemical process industry on the basis of the hazards they pose of risk a fire, explosion and toxicity release.
Methods: This type of ranking enables the professionals to identify the more hazardous units from the less hazardous ones so that greater attention can be paid to the former. The key process subunits in the Iso-max unit were identified based on parameters such as process pressure, temperature and material value. In next step, the main parameters affecting the FETI were identified and estimated, and the Mond FETI index was calculated for each subunit. In addition, the criteria offset measures for each case were identified and their influences were studied.
Results: The results showed that the process route’s potential hazardous characteristics, such as major incidents, were associated with one or more of the following dangerous phenomena: thermal radiation, blast (pressure wave) and ejection of fragments, release of toxic materials and chemical concentration in the air. Intake amount assessments and the corresponding risk of exposure were also produced. By using statistical incident data of the risks of fire, explosion and toxicity, exposure risks can be estimated more realistically as probabilities. This approach is capable of comparing alternative processes to select the one which is inherently safest.
Conclusion: Using this method, the exposure risks in a process can be identified sooner, and proper risk management decisions can be made early in the process development or predesign stages.

Objectives: Improving self-care behaviours such as the early detection of any abnormal signs and symptoms in high-risk pregnancies, self-control of weight and control of blood pressure have essential roles in the prevention and reduction of maternal and infant mortality rates. In this study, we aimed to determine the effects of an educational intervention based on the self-efficacy theory on improving self-care behaviours among pregnant women.
Methods: This intervention study was conducted on 300 pregnant women that were referred to health centres in Zahedan was 2014. We used multi-stage random sampling from five different areas in the city of Zahedan, and selected participants according to inclusion and exclusion criteria. In each region, the women at two centres were randomized into two groups consisting of the intervention (n = 150) and controls (n = 150) groups. Data collection tools, including questionnaires (validity and reliability were confirmed respectively), that both groups completed before training. Two training sessions were conducted for the intervention group with practice lectures, questions and answers, focus groups and using slides and educational pamphlet. One and one-half months after the training intervention, both the intervention and control groups completed questionnaires.
Results: According to the results, knowledge scores changed by a mean of 3.37compared with 0.89, attitude 1.19 compared with 0.07, behaviour 1.01 compared with 0.63 and self-efficacy 2.47 compared with 0.23 in the intervention group after training, compared to the control group. In addition, an independent sample T-test statistical test showed that the difference between the two groups was significant (p < 0.0001).
Conclusion: The use of an educational intervention based on self-efficacy theory had positive effects on the knowledge of self-care behaviours among participants.

Objectives: Although all jobs are stressful, professions contributing to human health are of utmost importance. Firefighting is a stressful and dangerous job where firefighters tend to have high levels of job stress. This study aims to explore occupational stress in firefighters.
Methods: This descriptive, cross-sectional study was performed in 2013. Participants comprised 244 firefighters from Yazd’s and Ahvaz’s fire departments. The data were collected using the HSE job stress questionnaire and analyzed using SPSS 21 software.
Results: The participants’ age ranged from 25 to 54 years, with a mean of 39.02 ± 7.44. The working history of the participants was 1 to 28 years, with a mean of 13.14 ± 7.17. There was a significant difference between the education and working history of participants and their stress levels (p = 0.013 and p = 0.001, respectively). Stress decreased with increasing age (p = 0.075 and r = ;minus0.114) and working history (p = 0.071 and r = 0.116), but these variables were not statistically correlated.
Conclusion: According to this study, healthcare politicians should develop training programs that focus on communication skills and staff and administrative support for fire workers. It appears that, due to the stressful job of firefighters, training programs should be designed with an emphasis on the importance of communication skills and on support from colleagues and authorities, in order to foster better health and performance in employees.
