Abstract

Introdution:Exposure to airborne pollutants such as lead (Pb) can cause health problems. Fuel stations are one of the places with a high risk of Pb exposure sourced from fuel or motor vehicle exhaust emissions. This research aims to know the effect of Pb exposure on hemoglobin levels and lung function in fuel station workers. Methods: This study was observational, analytical, and cross-sectional on 40 fuel station workers in South Banjarmasin District. Urinary Pb measurement was carried out by spectrophotometry, then the relationship to peripheral blood hemoglobin (Hb) levels and lung function was analyzed based on FEV1 (%), FVC (%), and FEV1/FVC ratio with a simple linear regression test. The data met the classical assumptions of normality, heteroscedasticity, and with no autocorrelation. If abnormal distribution was found, data transformation was carried out. Results: Study obtained urinary Pb levels below the normal threshold of 0.0356±0.0074 ppm. Respectively, urinary Pb levels did not have a significant effect on Hb levels (mean±SD:14.39±1.41, adjusted R2:6.2%, p=0.067), FEV1 (94.15±6.93, 5.8%, p=0.074) and FVC (89.68±6.24, 0.5%, p=0.380). However, urinary Pb significantly correlated with decreasing the FEV1/FVC ratio (90.87±3.36, 10%, p=0.026) with the equation y=96.550159.454x even without any obstruction value. Conclusion: This study showed that urinary Pb levels were normal. An increase in urinary Pb levels has a significant effect on decreasing the FEV1/FVC ratio. Prevention to reduce the health impacts of Pb needs to be taken. More research on at-risk populations with longer years of service needs to be done

Abstract

Introduction: An oil and gas refinery operates various equipment with specific functions for different processes. Each piece of equipment has potential hazards that can damage the equipment and injure or kill workers. This study focuses on the hydrotreated vegetable oil (HVO) export facility from the jetty loading area at an oil and gas company that processes flammable liquid using various equipment. Methods: The HAZOP method determined the hazardous spots, and the probability of each equipment failure corresponding to the system was also determined using fault tree analysis (FTA). Furthermore, every event tree analysis (ETA) output probability was also determined. The probability and radius of pool fire varied for different leak hole scenarios. The final steps are individual risk per annum and potential loss of life to measure the risk level of the system. Results: Based on HAZOP deviation scenarios, every operating equipment can potentially cause a pool fire. In FTA, scenarios were developed based on different leakage hole sizes, ranging from 1-3 mm, 3-10 mm, 10-50 mm, 150 mm, and >150 mm. The results indicated that leakage could occur across all operating equipment. Similarly, the ETA applied the same bore size scenarios. The consequence analysis yielded a worst-case outcome of pool fire and a best-case outcome of un-ignited fluid release. Subsequently, the pool fire output was modeled using ALOHA, which resulted in three heat flux zones: the red zone (10 kW/m²), the orange zone (5 kW/m²), and the yellow zone (2 kW/m²). Smaller leak holes had a higher probability but smaller pool fire radius. The initial risk of the export facility was unacceptable. Furthermore, insufficient safeguards contribute significantly to the resulting high-risk level. Two mitigations were implemented: adding safeguards and reducing worker hours. Conclusion: The final results showed that for every piece of equipment, the overall risk of the export facility became acceptable after mitigation..

Abstract

Introduction: Work fatigue is often a neglected problem because the symptoms are not specific and not visible directly to the naked eye. Occupational fatigue itself contributes more than 60% of all occupational accidents that occur in the workplace. The high rate of occupational fatigue that can contribute to work accidents is very interesting to be studied further related to the causal factors, including physical activity and muscular strength. The purpose of this study was to analyze the effect of physical activity and muscular strength with the incidence of fatigue in sedentary workers at Kalla Group located in Makassar, South Sulawesi. Method: The research is cross sectional study with samples in this study were sedentary workers who had relatively similar workloads and lifestyles which were then selected through simple random sampling calculations. This research uses ordinal regression statistical tests. Result: The test results obtained are p-value (p = 0.046) which means there is a significant relationship between fatigue and muscle strength, but there is no relationship between fatigue and exercise habits, no relationship between fatigue and smoking habits, no relationship between fatigue and staying up late and no relationship between fatigue and sitting time in a day on sedentary workers at Kalla Group, Makassar, South Sulawesi. Conclusion: Workers need to do light muscle stretching so that workers do not get tired easily when working in a static position for a long time and workers also need to adopt a healthy lifestyle.

Abstract

Introduction: The 2022 National Occupational Health and Safety (OHS) Profile in Indonesia shows that the human factor in safety is a factor that influences the risk of workplace accidents. The mining accidents statistical data in Indonesia, in which there was a 100% increase of workplace accidents in 2022, have given this industry an urgency to get a special attention to study risk-taking behavior at the workplace. At the organizational level, PT. XYZ (a mining contractor company in Indonesia) has internally measured its safety maturity level and is currently in calculative level, which indicates that the OHS management system has been implemented but the number of unsafe behaviors and unsafe conditions on site is still high. This paper explores quantitative results from research which aims to obtain an overview of employees’ internal factors leading to rule-breaking acts at the workplace. Methods: This paper uses cross-sectional design research with quantitative approach. Using stratified random sampling, a sample of 283 employees of PT. XYZ Site A participated in this study, ranging from managers, supervisors, and workers. Data were collected through a questionnaire with open-ended questions referring to a study from Safe Work Australia and analyzed quantitatively using statistical Chi-Square statistical test. Results: From the results of the Chi-Square test, the independent variables that have a value of Asymp. Sig. (2-sided) below 0.05 (95% CI) and lead to rule-breaking act at workplace are risk-taking behavior acceptance (0.018), normalizing minor accidents (0.002), and decision to take risk (0.000). Conclusion: Employees’ internal factors of risk-taking behavior acceptance, normalizing minor accidents, and decision to take risk have positive and significant effect on rule-breaking acts at the workplace. It is recommended that organizations implement a proper risk management with ALARP principle, safety empowering leadership, and safe behavior trainings to minimize rule-breaking acts at the workplace

Abstract

Introduction: Work-related musculoskeletal disorders (WRMDs) are one of the major health problems among physical therapists treating neurological patients. Therefore, this study aimed to determine the risk factors for developing WRMDs in physical therapists in South Korea treating neurological patients. Methods: This research is an analytical observational study with a cross-sectional design. In this study, 30 physical therapists who treat neurological patients were recruited by randomly selecting respondents to flyers posted throughout the hospital. To evaluate risk levels, during the transfer of the patient from the wheelchair to the treatment table and during treatment, the Rapid Entire Body Assessment (REBA) was performed. Moreover, physical therapists were assessed for musculoskeletal symptoms through the Nordic Musculoskeletal Questionnaire (NMQ) survey. Results: The findings revealed that during the treatment session, the REBA score was 43.33% for medium and high risk level and 13.33% for very high risk level. Meanwhile, during the transfer session, the REBA score was 40% for high risk level and 60% for very high risk level. The results of the Nordic musculoskeletal questionnaire showed that physical therapists felt significant pain in the wrist/hand, shoulders, neck, lower back, and knee. Conclusion: Physical therapists treating neurological patients have a high risk of developing WRMDs. Thus, changes need to be made regarding the working pattern of physical therapists, and more detailed evaluations of ergonomic risk factors are required.

Abstract

Introduction: Health status of an individual in paid employment is a function of many factors such as workplace settings, furniture, work design and tools used at work, among others. Based on this position, this study examined how work-related musculoskeletal disorders through workplace ergonomics determine non-teaching staff healthy living, and how each of the selected work-related musculoskeletal disorders caused by defective workplace ergonomics contributes to healthy living. Methods: This study was conducted among the non-teaching staff of selected public universities in south west Nigeria through quantitative approach that made use of descriptive research design with the use of structured questionnaire administered to collect data and both descriptive and inferential statistics were used to analyze data collected. Results: The study revealed that specific work-related musculoskeletal disorders caused by defective workplace ergonomics were of negative effect on non-teaching staff healthy living while others were not. Also, specific work-related musculoskeletal disorders (back pains and eyes dysfunctionality) examined against non-teaching staff healthy living were found to be detrimental to their health status while muscular pains, fracture, neck injuries, hand-arm vibration and bruises were of insignificant effect on the non-teaching staff healthy living. Conclusion: The study concludes that work-related musculoskeletal disorders through workplace ergonomics is an issue that management of universities should be mindful of to ensure staff healthy living as this is critical to job performance.

Abstract

Introduction: Since the first case of COVID-19 was detected in Indonesia, the government has implemented Large-Scale Social Restrictions to control the spread of the disease. However, these restrictions have had a negative impact on the economy. To address this, the government has introduced a new normal policy to restore activities while managing the risk of transmission. The government has adopted WHO guidelines through Minister of Health Decree No. 238 of 2020 to ensure COVID-19 workplace safety. This article aims to explore the barriers to COVID-19 workplace safety among Indonesian office workers. Methods: This qualitative research was conducted in DKI Jakarta and Surabaya from September to October 2020. In-depth interviews and observations were conducted with 22 informants selected purposefully. Thematic analysis was used, drawing on the Social-ecological Model (SEM) theory. Results: At the intrapersonal level, fear and perception barriers impact preventive actions against COVID-19. At the interpersonal level, peer influence and perceptions of the work environment affect adherence to office policies. At the organizational level, employee behavior is influenced by socializing, rules, and workplace amenities. Lastly, public policy enforcement is vital at the macro level to reduce risky behaviors among office workers. Conclusion: Implementing comprehensive protocols across different levels is crucial to creating COVID-19 workplace safety. This requires increased public awareness and consistent enforcement, including strengthening organizational policies.

Abstract

Introduction: Emotional eating, as a method of stress coping mechanism in workers, makes a person tend to consume more energy daily. Uncontrolled daily intake will lead to a high probability of a person developing metabolic syndrome in the future. The aim of this study is to analyze the relationship between working style to stress, coping mechanisms, and metabolic syndrome risk in sedentary workers. Method: This research is a cross-sectional study conducted at Kalla Group. Measurement of blood biochemistry (total cholesterol, blood glucose and uric acid) used FORA 6 Plus, blood pressure was measured using Omron digital sphygmomanometer 7130, waist circumference using Seca 201 measuring tape, and height using GEA microtoise. Measurements of body composition used Omron Karada Scan Hbf 375 Body Fat Composition Monitor Bioimpedance Analyzer. Stress was measured using Kessler Psychological Distress Scale K10 instrument. Coping mechanism was measured using Carver’s COPE Inventory. Result: Significant correlations were found for cholesterol levels (p = 0.044), waist circumference (p = 0.036), blood pressure (p = 0.042), and muscular percentage (p = 0.032). No significant correlations were found between working style for stress level (p = 0.683), coping mechanisms (p = 0.744), blood glucose (p = 0.128), uric acid (p = 0.380), visceral fat percentage (p = 0.128), and fat mass (p = 0.547). Conclusion: Significant correlations were found between working style for cholesterol levels, waist circumference, blood pressure, and muscular percentage, suggesting that different working styles may influence these health aspects.
