Abstract

The hydro cracker complex (HCC) operating area is one of the areas with the most use of chemicals, and several workers complain about the noise in that area. This research determines the level of health hazard risk through a health risk assessment (HRA) focusing on physical, chemical, and biological hazards in the HCC area aims to improve the health status of workers and as a basis for developing occupational health programs to minimize the risk of occupational diseases. This study used primary data (walkthrough survey, interviews, heat stress measurements, noise, lighting, chemicals, fungi, and bacteria) with a cross-sectional method referring to the International Council on Mining & Metals (ICMM). The dangers of gasses and chemicals are the most common hazard in the HCC area. Based on the risk assessment, five hazard ratings with the highest risk were obtained, namely noisy environment (extreme), H2S gas (extreme), heat stress (extreme), NH3 gas (high risk), and hydrocarbon vapors (high risk). Existing controls and control recommendations must be applied comprehensively and consistently so that the company can accept the resulting residual risk value.

Abstract

Powered hauling equipment is one of the most critical operational elements in the mining sector. Haulage is a significant hazard for the mining industry, accounting for over half of all mining-related fatal accidents yearly. Identifying safety risk variables is the foundation of risk assessment and accident prevention. This study aimed to identify risk variables and prevention techniques to reduce occurrences among truck drivers in coal mining. This research approach is a scoping review with the PRISMA Extension for Scoping Reviews (PRISMA-ScR). Thirty-five articles were reviewed based on the results of inclusion and exclusion criteria. Data analysis was performed using content analysis. The results show that human, environmental, machine and organizational factors contribute to the risk among truck drivers in coal mining. Safety culture, staffing and scheduling, training and education, policy and procedure implementation, and technology deployment are all part of the accident prevention plan. The central government should pay particular attention to the employment conditions of workers in cities with decreased resources and develop policies to prevent mining-related diseases in local communities.

Abstract

The High-Temperature Gas-Cooled Reactor (HTGR), a promising candidate for Generation IV nuclear reactors, boasts superior inherent passive safety features and a continuous fuel handling system. This system employs multi-pass cycles, utilizing pneumatic and gravitational mechanisms to feed, circulate, and unload the pebble bed fuel element. This paper presents a descriptive analysis assessing the safety risk of the fuel handling system design in HTR-10. The Hazard and Operability Study (HAZOP) methodology is employed to identify hazard parameters, deviation limitations, causes, impacts, and potential risks to the system’s main components. The establishment of probability scales, consequence criteria, risk level ratings, and control activities adheres to the ISO 31000 standard. Primary data were gathered through expert interviews, while secondary data were sourced from design layout documentation, literature reviews, and safety analysis reports. Six main components - the elevator, core, singulator, failed fuel separator, burnup measurement, and distributor - were selected as assessment nodes from the piping and instrumentation diagram. The assessment revealed that each node initially presented a moderate to extreme risk potential (risk level rating C to E). However, after applying the effectiveness index of the designed control, the residual risk for all nodes was reduced to an acceptable limit (risk rating A - very low). Therefore, the fuel handling system design already incorporates adequate control activities to mitigate potential safety risks due to system component failure. As safety risk assessment is dynamic, it should be reviewed periodically or whenever there are design changes at any project stage. This ensures the safety risk magnitude is consistently known and managed effectively.

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

The high operational risks in the coal mining sector, including repeated work accidents, emphasize the urgency of implementing a resilient and adaptive safety culture. This study aimed to evaluate the implementation of Resilience Safety Culture (RSC) at PT. X. This study is a descriptive quantitative study. The subjects of the study were 300 employees selected using stratified random sampling techniques. Related data were collected by filling out a structured questionnaire based on James Reason's safety culture framework and Erik Hollnagel's Resilience Engineering principles. The collected data were analyzed descriptively and then presented categorically. The results of the study indicated that PT. X excels in the learning culture dimension through continuous training and incident investigation, but is still weak in response capabilities due to bureaucratic constraints and the less than optimal implementation of Stop Work Authority (SWA). Furthermore, it was concluded that PT. X needs to strengthen worker autonomy in emergency situations, simplify reporting flows, and prioritize safety over production to create a more resilient and adaptive safety system.Keywords: resilience engineering; safety culture; resilience safety culture; mining industry ABSTRAK Tingginya risiko operasional di sektor tambang batubara, termasuk kecelakaan kerja yang berulang, menekankan urgensi penerapan budaya keselamatan yang tangguh dan adaptif.

Abstract

Online motorcycle taxi riders, a vulnerable group on the road, are more susceptible to serious injury than non-motorcycle riders. This study analyzed a correlation between daily income targets, passenger pressure, risk perception, safety attitudes, and risky riding behavior. This cross-sectional study used a semi-quantitative approach by collecting online-based questionnaires from 500 online motorcycle taxi riders in Jakarta, and 50 of them were obtained through offline interviews. The findings revealed a significant relationship between daily income targets, passenger pressure, risk perception (danger level, stochastic evaluation, and safety priority), safety attitudes (pragmatic attitude to rule violations and dissatisfaction with traffic rules), and risky riding behavior, with a p-value of <0.05. In particular, a pragmatic attitude to rule violations was the most impactful on risky riding behavior. Online motorcycle taxi companies should provide regular training on traffic laws and safe riding practices to improve road safety. This holistic approach may enhance safety through education, passenger awareness, and rigorous management.
