Impact of simulation fidelity on identifying swing-over hazards in virtual environments for novice crane operators

Crane-related accidents often occur due to failure in timely and accurate hazard identification. Virtual Reality (VR) technology facilitates immersive environments for improving hazard identification without real-world consequences. However, the impact of simulation fidelity on hazard identification performance, particularly for novice crane operators, remains underexplored. This paper examines how simulation fidelity and task complexity affect hazard identification performance among novice operators through a VR experiment with two fidelity and two complexity levels. Findings demonstrate high-fidelity (HF) scenarios significantly improve hazard identification success rate and speed for swing-over hazards but extend task completion times. Task complexity modulates simulation fidelity's impact on task completion, with significant differences between fidelity levels observed only under low complexity. These insights inform the design and calibration of simulation fidelity in VR platforms, potentially improving training efficacy and crane lifting safety for novice operators.

Comparative Analysis of Hazard Identification and Risk Assessment Methods in Ağrı Cement Factory: Fine-Kinney vs. 3T Approach

Occupational health and safety is essential to protect, maintain and improve the physical, psychological and social well-being of employees and to prevent harmful factors. One way to prevent occupational hazards is to identify them in the workplace. Therefore, providing information to assist in making the necessary decisions to reduce occupational hazards, and conducting hazard identification and risk assessment will contribute significantly. In this study, the risks identified at Ağrı Cement Factory were classified using the Fine-Kinney method and the 3T risk assessment method, and the results were compared. The 3T method is superior to the Fine-Kinney method because of its modular structure. The high risks that require immediate action in the Fine-Kinney method appear to be prioritized similarly in the 3T method as well. However, in the Fine-Kinney method, significant, possible, and risks are considered among the top 3 priority risks, while in the 3T method, they are considered among the top 2 priority risks. It has been observed that a risk assessment utilizing the Fine-Kinney method will be successful if continuously updated. Difficulty in selecting the probability component has led to elevating risk values in the Fine-Kinney risk assessments by selecting a higher level of risk. Although both methods exhibit different approaches, the 3T methodology has been understood to provide a comprehensive perspective by considering risk in terms of threat, performance, and harm. This approach has addressed different dimensions to understand the origins, impacts, and consequences of risks. On the other hand, the Fine-Kinney Risk Assessment Method, relying on weighting and scoring factors specific to project characteristics and factors, has been reported to evaluate risk in a more analytical manner. It has been concluded that this methodology will be successful in calculating risk scores by considering specific project characteristics and risk profiles.

Proposal for Prevention of Occupational Disease Risk Using the Hiradc Method at PT X in the Dyeing Department

People in this era have various needs in carrying out life. The needs that need to be used by the community have multiple kinds of things, such as clothing. Clothes used by the community go through various processes before becoming finished goods. Before becoming ready-to-wear, clothes came from raw materials such as fabric rolls. There are multiple production processes, such as yarn, fabric, chemical dyeing, etc. One of the places where fabrics are produced is textile factories. A textile factory is a company that produces products in the form of fabrics. The manufacture of fabrics that occur in textile factories must involve mixing chemicals so that the fabric has good quality. The process of mixing these chemical substances involves workers, and the chemical substances used are classified as Hazardous and Toxic Materials (B3), so these chemicals can have a bad impact on their workers if there is physical contact with the worker's body. Exposure to chemicals in the worker's body will cause a risk of developing Occupational Diseases (PAK). Therefore, in this study, data will be processed to prevent workers' risk of Occupational Diseases (PAK) using the HIRADC (Hazard Identification, Risk Assessment, and Determining Control) method. The proposal given in this study is a proposal for the use of Personal Protective Equipment (PPE) and Standard Operating Procedure (SOP) for preventive measures against Occupational Diseases (PAK) for workers

Grouping of short alkyl-chain branched carboxylic acids for developmental toxicity

Read-across (RAx) and grouping of chemicals into categories are well-known concepts in toxicology. Recently, ECHA proposed a grouping approach for branched-chain carboxylic acids (BCAs) including more than 60 branched-chain saturated carboxylic acids for hazard identification. Grouping was based only on structural considerations. Due to developmental effects of two members, ECHA postulated that “all short carbon chain acids … are likely reproductive and developmental toxicants”. This work analyzes available data for BCAs. The number of compounds in the group can be significantly reduced by eliminating metal and organic salts of BCAs, compounds of unknown or variable composition, and complex reaction products or biological materials (UVCB compounds). For the resulting reduced number of compounds, grouping is supported by similar physicochemical data and expected similar biotransformation. However, analysis of adverse effects for compounds in the group and mechanistic information show that BCAs, as a class, do not cause developmental effects in rats. Rather, developmental toxicity is limited to selected BCAs with specific structures that share a common mode of action (histone deacetylase inhibition). Thus, the proposed grouping is unreasonably wide and the more detailed analyses show that structural similarity alone is not sufficient for grouping branched-chain carboxylic acids for developmental toxicity.

RISK ASSESSMENT OF BAGGED FERTILIZER UNLOADING ACTIVITY AT TUKS PUSRI BANYUWANGI BRANCH

The port is one of the distribution centers for goods in which there are loading and unloading activities. Loading and unloading activities sometimes involve loading and unloading personnel and heavy equipment which raises the potential for hazards that can cause work accidents and damage to goods. The purpose of this research is to conduct a risk assessment using the HIRARC (Hazard Identification, Risk Assessment and Risk Control) method on bagged fertilizer unloading work in the TUKS PUSRI Banyuwangi Branch Port area. The stages of bagged fertilizer unloading work activities include the unloading activity process, which consists of five work stages: opening the ship's hatch, workers (stevedores) entering the hatch, stevedoring, cargodoring, and delivery. The results stated that from a total of 5 work stages, 26 sources of hazards were identified with 6 sources of low risk level hazards at 23%, 7 sources of moderate risk level hazards at 27%, 6 sources of high risk level hazards at 23%, and 7 sources of very high risk level hazards (extreme) at 27%. Control measures that can be implemented are conducting briefings on OHS (Occupational Health and Safety) before starting work activities, supervision of compliance with the use of complete personal protective equipment and also the need for sanctions for workers who do not comply with the rules for using personal protective equipment.

Emerging Trends of Immunosensors Development for Detection of Food Toxins

The present study highlights the ongoing threat of foodborne illnesses to public health, primarily caused by bacterial pathogens. Despite advancements in conventional microbiological testing techniques, which are sensitive but time-consuming, challenges remain in ensuring timely detection of contaminants throughout the food supply chain. The Hazard Analysis Critical Control Point (HACCP) system is recognized as a more effective approach to ensuring food safety, emphasizing proactive identification and control of hazards at critical points in production. Emerging technologies like quantitative polymerase chain reaction (PCR) and biosensors offer faster and more accurate detection methods, although with certain limitations. Biosensors such as ELISA, SPR, and electrochemical immunosensors, in particular, show promise due to their high sensitivity and specificity, enabling rapid detection of a wide range of contaminants. This paper underscores the importance of integrating advanced technologies with established food safety protocols to enhance the safety and quality of food products, benefiting consumers, producers, and regulatory agencies alike.

Model of the Formation of Work Safety Culture in Polish Mining Enterprises

The article presents the results of research on the level of work safety culture, which is an important element influencing the organisational culture in mining enterprises. The article aims to measure the safety culture among managers in Polish hard coal mines. The assumed goal was achieved in the area of literature and empirical research. Research shows that the precise identification of hazards defined the thematic areas shaping safe working conditions in underground mines. The main part of the work was to survey 135 employees in 3 hard coal companies in Poland. The questionnaires were developed in cooperation with mining experts, and the 5-point Likert scale was used to evaluate individual questions. This methodological approach identified the subjective feelings and experiences of employees for building appropriate attitudes and behaviours that shape the organisational culture. The use of a culture grid enabled the creation of seven thematic groups of safety areas related to the so-called referents of organisational culture. The result of the empirical research is to propose an approach for the transformation of safety culture in the selected area for mining companies. The approach uses the organisational culture grid to shape the attitudes and behaviours of employees, which identifies and designates weak areas, defining them as unsatisfactory and unacceptable, and being the key conclusion of the research.

Characterization, hazard identification, and risk assessment of volatile organic compounds in Poly(butylene adipate-co-terephthalate)-based food contact articles

The chemical safety of poly (butylene adipate-co-terephthalate) (PBAT) based food contact articles (FCAs) has aroused increasing toxicological concerns in recent years, but the chemical characterization and associated risk assessment still remain inadequate as it fails to elucidate the distribution pattern and discern the potential genotoxic and carcinogenic hazards of the identified substances. Herein, the volatile organic compounds (VOCs) in 50 batches of PBAT-based FCAs of representative categories and 10 batches of PLA and PBAT pellets were characterized, by which 237 VOCs of 10 chemical categories were identified and exhibited characteristic distribution patterns in the chemical spaces derived from their molecular descriptors. Chemical hazards associated with the identified VOCs were discerned by a hazard-driven classification scheme integrating hazard-related knowledge from multiple publicly available sources, and 34 VOCs were found to bear genotoxic or carcinogenic hazards and to feature higher average molecular weight than the other VOCs. Finally, the Risk and hazard quotient (HQ) calculated as the metrics of risk suggested that all identified VOCs posed acceptable risks (Risk<10–4 or HQ < 1), whereas oxolane, butyrolactone, N,N-dimethylacetamide, 2-butoxyethanol, benzyl alcohol, and 1,2,3-trichloropropane posed non-negligible (Risk>10–6) genotoxic or carcinogenic risk and thus should be of prioritized concern to promote the chemical safety of PBAT-based FCAs.

Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT).

Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose-response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An "effect severity" AF (ESAF) is employed in some regulatory contexts. An ESAF of 10 may be incorporated in the derivation of a health-based guidance value (HBGV) when a "severe" toxicological endpoint, such as teratogenicity, irreversible reproductive effects, neurotoxicity, or cancer was observed in the reference study. Although mutation data have been used historically for hazard identification, this endpoint is suitable for quantitative dose-response modeling and risk assessment. As part of the 8th International Workshops on Genotoxicity Testing, a sub-group of the Quantitative Analysis Work Group (WG) explored how the concept of effect severity could be applied to mutation. To approach this question, the WG reviewed the prevailing regulatory guidance on how an ESAF is incorporated into risk assessments, evaluated current knowledge of associations between germline or somatic mutation and severe disease risk, and mined available data on the fraction of human germline mutations expected to cause severe disease. Based on this review and given that mutations are irreversible and some cause severe human disease, in regulatory settings where an ESAF is used, a majority of the WG recommends applying an ESAF value between 2 and 10 when deriving a HBGV from mutation data. This recommendation may need to be revisited in the future if direct measurement of disease-causing mutations by error-corrected next generation sequencing clarifies selection of ESAF values.

Hazard Identification and Risk Assessment of Biogas Plant with Proton Exchange Membrane Fuel Cell Technology

Biogas-fed proton exchange membrane fuel cell (PEMFC) plants offer a sustainable energy solution, but their operation can pose significant hazards and risks. Ensuring the safety of these plants is paramount, especially given the potential for fires, explosions, and chemical exposures. This study evaluated hazards and risks in biogasfed proton exchange membrane fuel cell (PEMFC) plants using six analytical methods: Dow's fire and explosion index (FEI), Dow's chemical expo-sure index (CEI), Hazard and Operability Study (HAZOP), Risk Matrix Analysis (RMA), Bayesian Network (BN) and ALOHA® software hazard modelling. The FEI analysis revealed that the anaerobic digester and bio-gas storage tank exhibited severe hazards (FEI =170), thereby signifying the highest risks within the plant. CEI analysis revealed the spread of the highest hydrogen sulfide (H2S) concentration up to 129 meters from the anaerobic digester and storage tank location. Further assessment was conducted, calculating risk values using the RMA and performing additional HAZOP analysis specifically for these units. The results confirmed similar risk levels (4-20) between the units, except for a higher explosion risk in the storage tank. The novelty of this research lies in the application of Bayesian Network (BN) analysis. In addition to assessing the hazards associated with PEMFC, our BN analysis reveals that the risk of fire attributed to PEMFC ranges between 10% and 18%, while the risk of explosion falls within the range of 3% to 17%. Based on the hierarchy control concept, several effective mitigation controls were proposed to enhance the safety of biogas-fed PEMFC plants. In future research, a deeper exploration of human error and equipment malfunctions within hazard modelling is crucial for a more precise hazard assessment.
