Workplace Risk Factors Assessment in North-Azadegan Oil Field Based on Harmful Agents Risk Priority Index (HARPI).

Background: Considering the necessity of health risk management, the present study conducted to provide a comprehensive model for identifying, evaluating, and prioritizing occupational health risks in an oilfield. Methods: We conducted this descriptive-analytical cross-sectional study in 2022 at the North-Azadegan oil field in Iran. The occupational health risk was assessed using the "Harmful Agents Risk Priority Index" (HARPI) method. Results: Among the employees for the office section in all job groups, ergonomic risks due to people's posture while working has the highest risk score and is the most critical risk for implementing corrective actions. In the operational section, for the HSE group, benzene, the production group, Electromagnetic Fields (EMFs), and other groups, undesirable lighting has the highest risk score, and exposure to Toluene, Ethylbenzene, Xylenes (TEX) has the lowest risk score. In this oil field, controlling exposure to benzene, correcting ergonomic conditions, and controlling noise exposure, with scores of 81.3,74.85 and 71.36, have the highest priority, respectively. Sequentially, Toluene, Xylene, and ethylbenzene, with scores of 10.25,11.61, and 11.61, have the lowest control priority. Conclusion: The proposed model can prioritize the workplaces' harmful agents based on the HARPI score due to exposure to chemicals, physical factors, and analysis posture.

Safety culture and perception of warning signs of chemical hazards among hospital cleaning workers: a cross-sectional study.

BACKGROUND: Due to the type of activities and the long-term exposure to chemicals, hospital cleaning workers require the necessary knowledge about the chemicals used and proper safety culture. This study aimed to evaluate the safety culture and perception of hospital cleaning workers' warning signs of chemical hazards. METHODS: This cross-sectional study was conducted in 2022 with the participation of 68 cleaning workers with the mean age ± (SD) and work experience ± (SD) of 36.19 ± (7.619) and 9.21 ± (5.462), respectively, in four selected Tehran hospitals in Iran. After ensuring the confidentiality of the received information and completing the demographic information checklist, each participant completed Global Harmonization System (GHS) sign perception and the safety culture questionnaires in this survey. Data were analyzed using regression and Pearson correlation tests. RESULTS: This study showed that the participant's correct perception in nine cases (81.8%) of presented GHS signs was lower than the ANSI Z535.3 standard. Among the investigated signs, "Flammable substances" and "Harmful to the environment" signs had the highest, and "Skin irritant" signs had the lowest correct perception. In addition, it was found that 55 people (80.9%) had an overall positive attitude toward the safety culture. The levels of "Work environment" (83.8%) and "Information exchange" (76.5%) had the highest and lowest positive scores for safety culture. Furthermore, there is a direct and significant relationship between the overall score of safety culture and the overall perception of the symptoms of GHS (CC = 0.313, P = 0.009). CONCLUSION: According to the obtained results, it is recommended to take the necessary measures to increase the employees' perception of the signs of chemical substances and improve their safety culture.

The effects of personal protective equipment on heart rate, oxygen consumption and body temperature of firefighters: A systematic review.

BACKGROUND: Fire extinguishing operations are carried out by firefighters equipped with personal protective equipment (PPE) in dangerous environments. Although PPE protects firefighters, it can affect many physiological parameters. OBJECTIVE: This study aimed to investigate the effects of PPE on firefighters' heart rate (HR), oxygen consumption (OC) and body temperature (BT). METHODS: This systematic review thoroughly reviewed relevant articles in the reliable databases "Web of Science", "Embase", "IranDoc", "IranMedex", "SID", "Magiran", "Google Scholar", "PubMed" and "Scopus" from 2010 to 2021. Some of the used search terms were "firefighters", "personal protective equipment", "heart rate" and "oxygen consumption". RESULTS: Out of the 405 studies identified through the systematic search, 18 articles were eligible according to the Joanna Briggs Institute (JBI) checklist, among which 11 studies were conducted in North America, three in Asia, two in Europe, and two studies in Oceania. According to the review of studies, PPE increased HR, BT, and OC. The type of PPE components, the weight of the equipment, the kind of activity of firefighters, and weather conditions were among the influencing parameters on the extent of PPE's influence on these physiological parameters. CONCLUSION: The results of the studies show that PPE separately and collectively affects the physiological parameters of HR, BT and OC. To reduce these effects, it is necessary to pay attention to several items, including the weight of PPE, the type of PPE ingredients in different weather conditions, and the type of activities of firefighters in PPE design.

Bakers are among the people exposed to heat stress continuously and daily. This review study aimed to investigate the effect of heat stress on bakers. Methods: In this review study, the related articles based on keywords were reviewed using "IranMedex", "Science Direct", "PubMed", "Scopus", "Web of Science", "SID", "Google Scholar", and "Magiran" databases from the years 2000 to 2021. The used search terms were "Heat stress", "Heat strain", "Heat exposure", "Heat waves", "Workplace", "Baker", and "health effects". In order to extract the required data, all parts of the articles have been reviewed. Results: Out of the 16 studies reviewed in this study, 43.75% were cross-sectional, 25% were descriptive cross-sectional, and 31.25% were performed according to other study designs. In all of the studies, the WBGT index was used to assess ambient heat stress. In most studies, the mean exposure temperature was higher than the WBGT-ACGIH limit, especially among traditional bakery workers. The findings showed that exposure to thermal stress significantly affects some hematological parameters of blood, oxidative stress, heart rate, and body temperature. Conclusion: The situation of heat stress in the bakery environment is worrying in terms of health and reduced productivity of employees. Therefore, it is essential to take the necessary preventive and control measures to reduce heat stress and the resulting strain.

Study of suicidal thoughts and intentions with regard to job stress among female medical students living in dormitory with a mental health promotion approach.

BACKGROUND: Medical students are exposed to stresses which have irreversible consequences, such as suicidal ideation. The present study aimed to investigate the level of occupational stress in medical students and its relationship with the prevalence of suicidal ideation and attention among them and then provide mental health promotion approaches. MATERIALS AND METHODS: This cross-sectional descriptive study was performed on 325 undergraduate medical students residing at the dormitory of Shahid Beheshti University of Medical Sciences. The sample size was determined by the census method. Osipow and Suicide Behaviors Questionnaires were used to measure job stress and suicidal ideation, respectively. The condition of entry into the study was living in the dormitory and spent at least one semester. Linear regression and logistic regression were used to examine the relationship between variables. RESULTS: The mean score of occupational stress among students with a mean age of 21 (±2.18) years was 158.84 (±27.07) and 60% (n = 180) of students had high levels of stress. There was a significant relationship between age and educational level with stress level and suicidal ideation (P < 0.05). They had the highest effect on stress (P = 0.031) and suicidal ideation (P = 0.001), respectively, among students. High level of stress was 11.829 times more likely to have suicidal thoughts than low-stress level (P < 0.001). CONCLUSIONS: Stress and suicidal ideation are much higher in students of lower semesters and lower ages than students with higher semesters. Students should learn how and with what approach to control and manage exposure to stressors. Measures such as holding stress management training courses as well as managing stressful situations are among the effective measures in improving mental health and reducing stress levels and its effects.

Effectiveness of educational intervention on reducing oxidative stress caused by occupational stress in nurses: A health promotion approach.

BACKGROUND: Nursing is one of the most stressful occupations. Educational intervention regarding stress management can play an important role in reducing occupational stress among nurses The present study aimed to determine the effectiveness of educational intervention on reducing oxidative stress caused by occupational stress in nurses: A health promotion approach in a hospital in western Iran. MATERIALS AND METHODS: The present interventional study was performed in 2019 among 92 nurses working at the Kosar Hospital located in the city of Sanandaj in the country of Iran. Occupational stress was evaluated using the Osipow Occupational Stress Questionnaire. Oxidative stress was measured by taking blood samples and measuring the enzymatic activity of superoxide dismutase (SOD), malondialdehyde, and catalase (CAT) using SOD, malondialdehyde (MDA), and CAT kits. Educational intervention was carried out in the second stage. Three months after the intervention, data were taken again. RESULTS: The results of the present study indicated that there was a significant difference in occupational stress between before and after the educational intervention (P < 0.05). A significant reduction in MDA (P = 0.038) and SOD (P = 0.048) was observed after educational intervention, but this was not the case for CAT (P = 0.592). There was no significant correlation between occupational stress with oxidative stress parameters before and after the educational intervention (P < 0.05). No significant difference in occupational stress was observed between men and women. Among the oxidative stress parameters under evaluation, MDA was higher among men compared to women and this was statistically significant. CONCLUSIONS: Educational intervention regarding occupational stress is effective in reducing oxidative stress among nurses. The group meetings teach stress management to the participants and enable them to better manage their stress by utilizing their own capabilities. Thus, attention to this issue is vital in maintaining the mental and physical health of nurses and, in turn, improves the quality of care rendered.

Effectiveness of training program in manual material handling: A health promotion approach.

BACKGROUND: Even in an era of automation and digitalization, Manual Material Handling (MMH) can be called the most common industrial task. The aim of this study was to evaluate the prevalence of musculoskeletal disorders (MSDs) induced by manual handling tasks on the workers of a printing factory in Tehran in 2017 and then to evaluate the effectiveness of a training intervention based on health promotion. MATERIALS AND METHODS: This study had quasi experimental design and was conducted on 40 men. First, demographic data were collected and the Nordic questionnaire was used to determine the prevalence of MSDs in workers. Then, MMH tasks were assessed using Manual Handling Assessment Chart (MAC). A short training course was designed to promote health. Finally, the same MMH tasks were re-evaluated 3 months after the training intervention. RESULTS: Among the various tasks, the highest prevalence of work-related MSDs (WMSDs) was observed in the lower back (77.5%) and shoulder (62.5%). Based on the final scores of the MAC method, the jobs that received the highest scores were cutting (individual lifting), with 22 scores and action level "immediately necessary," cutting (individual load carrying), with 15 scores with action level "urgently needed." Arranging the forms (individual lifting) received a similar score. After the training intervention, the estimated risk level reduced by 12, 9, and 6 points, respectively, reaching a safe action level, i.e., "necessary in the future." CONCLUSION: The results demonstrated that educational interventions might be equally effective in low-technology work environments. More in general, the MAC method can be used to make informed planning of educational interventions against WMSDs risk in MSDs. This health promotion approach is critical for care of human recourse.
