Introduction: Needlestick and sharps injuries (NSSIs) represent an existential occupational hazard risk to orthopaedic surgeons during their career due to the interaction with various devices, instruments and bone fragments. Consequently, NSSIs have the potential to transmit infections such as Hepatitis B (HBV), Hepatitis C (HCV) and Human Immunodeficiency Virus (HIV) leading to serious illness. The purpose of this cross-sectional study was to identify the clinical settings predisposing orthopaedic surgeons to NSSIs and assess their adherence to safety protocols in the Indian context. Materials and Methods: An online cross-sectional survey of 618 orthopaedic surgeons in India, stratified by experience into two groups: under five years and with 5 years or more was undertaken. The data were collected via an expert-validated online questionnaire to evaluate demographic distribution, injury characteristics, knowledge of safety protocols, and adherence to these protocols. Descriptive statistics summarized the data, Chi-square tests assessed variable associations, and odds ratios were computed for significant variables. Ethical integrity was maintained via electronic informed consent and for confidentiality assurances. Results: The study revealed that orthopaedic surgeons with less than 5 years of clinical experience had higher risks for NSSIs as compared to those with 5 or more years of clinical practice. Conversely, the latter group was more susceptible to bone spike injuries and viral positive needlestick incidents. The analysis shows that whilst the more experienced practitioners displayed greater proficiency in the application of universal precautions and NSSI prevention, they were also less likely to report injuries, often due to discomfiture. Risk profiles were consistent across different practice settings and affiliations, regardless of experience level. Conclusion: This cross-sectional study reveals less experienced orthopaedic surgeons face higher risks of NSSIs, possibly due to inadequate education or awareness. More experienced practitioners encounter distinct risks, likely owing to long-term exposure and traditional practices. There is an immediate need to raise awareness of the potential risks of NSSIs, enhanced education, appropriate training, collaboration with the hospital risk management team and developing a culture of transparent reporting to mitigate these risks. The emphasis should be on reducing the incidence and fostering open reporting of NSSIs to protect clinicians and promote health safety. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate all studies which used the micronucleus assay using oral cells in the attempt to understand whether such technique is efficient in evaluating genotoxicity in gas station attendants. Full manuscripts from 16 studies were carefully selected by the authors. Our results demonstrate that continuous exposure to derivatives of petroleum may lead to genotoxic effects since all studies demonstrated positive findings (16 out of 16) and 11 of them had a strong or moderate final rating. In summary, our results reveal that gas station attendants are occupationally exposed to genotoxic agents and that the micronucleus assay in oral mucosa is indeed an effective method to evaluate genotoxicity in this specific case. Such findings are very important for protecting these professionals who are continuously exposed to chemicals for long periods. [ABSTRACT FROM AUTHOR]

As a result of firing pulverized coal in thermal power plants, enormous amounts of fly ash (FA) are produced as industrial waste. The release into the atmosphere and storage of this industrial waste remains one of the major environmental problems that threaten human health by contributing to air, water, and soil pollution. The recovery and reuse of FA in the construction industry is the only economic solution to the existing problem. In this study, the potential radiological risk caused by the usage of FA in concrete and cement production as a main component and its storage in landfill sites was evaluated for people and works by estimating radiological parameters (activity concentration and alpha index, annual effective doses, and the corresponding excess lifetime cancer risks) based on activity concentrations of terrestrial radionuclides in FA. Also, the radiological risk to the workers working in the FA landfill site was evaluated using the Residual Radioactivity Onsite 7.2 code. The average activity concentrations of terrestrial radionuclides in FA samples from the Tunçbilek lignite coal-fired thermal power plant at Kütahya province of Turkey were measured as 417, 156 and 454 Bq kg−1 for 226Ra, 232Th and 40K, respectively. When using up to 35% by mass of FA in cement and concrete, the average values of the radiological parameters revealed that they were within the recommended safety limits. However, code estimations showed that a regular worker in FA storage would be exposed to a total effective dose rate greater than 3 mSv y−1. [ABSTRACT FROM AUTHOR]

BACKGROUND: Quantitatively analyzing the impact of UV radiation and noise during welding operations is essential to assess the exposure, identify potential hazards, and develop targeted safety protocols to ensure worker safety and adherence to safety regulations, especially in developing countries with inadequate adherence to safety standards and resources. OBJECTIVES: This study employs machine learning for predicting ultraviolet radiation and noise levels during welding, emphasizing worker safety. The focus is on the Indian foundry sector to gauge actual exposure vis-á-vis safety standards. MATERIALS AND METHODS: Ultraviolet radiation and noise emitted during the welding of a ferrous alloy were collected from three foundries in Agra, India. Five machine learning (ML) algorithms were applied for data analysis and prediction of UV radiation and noise levels, and a relative performance comparison was carried out on the compiled data against safety standards. RESULTS: Out of all the ML algorithms applied, the Support Vector Machine regression algorithm (RMSE = 356.93) obtained the best performance on UV radiation data, and the Random Forest algorithm (RMSE = 11.4) was found to give the best results for the noise level prediction task. CONCLUSIONS: This work represents the first known application of machine learning techniques for predicting UV radiation and noise levels in arc welding processes. The results show the efficacy of algorithms such as SVM regression and Random Forest for the problem. Further, the datasets and ML algorithms implemented in the work will be made openly available to support further research endeavors in this and related areas. [ABSTRACT FROM AUTHOR]

BACKGROUND: Like other things, psychological safety has a too-much-of-a-good-thing effect on the risk prevention process. There are warranted systematic and theoretical discussions on both positive and negative influences of psychological safety, which provide useful guides to handling potential risks for workers. OBJECTIVE: This study focuses on the psychological safety analysis of work safety for workers in high-risk industries through the construction of a theoretical model, illustrating that a higher level of psychological safety is not better. METHOD: This study explores the impact of workers' psychological safety on the potential risk of work safety by conducting a comprehensive analysis of relevant literature and employing inductive reasoning and analogy methodology. RESULTS: We systematically reviewed the research background and several hypotheses of psychological safety, described the relationship between psychological safety and risk prevention from three levels, and constructed the threshold initial, special, and extended model of psychological safety to reveal the importance of workers' psychological safety when handling potential risks. CONCLUSION: This research effectively describes the influence of high, moderate, and low levels of psychological safety on the risk prevention of work safety, which provides a psychological model guide to developing measures for the improvement of work safety management.

BACKGROUND: Safety design covers proactive actions as it analyzes accident risks early in the enterprise life cycle, and considers the designer acting on accident prevention as a member of the construction team. OBJECTIVE: This paper proposes an accident investigation to establish links between accident causes and design to support Prevention through Design (PtD) tools. METHODS: This article analyzed more than a thousand severe and fatal accident cases in the construction sector. A systematic analysis method was structured based on descriptions of accident causes and measures that could be taken to avoid accidents. RESULTS: Analyzing the severe and fatal accidents, the safety measures implemented in the project design could avoid at least 23.6% of the events. As a result, the architectural and structural designs were more effective in accident prevention. The reference percentages and the design types that are more effective in preventing accidents are analyzed through a representative sample of the analysis of the accident. CONCLUSIONS: This research contributes to applying safety guidelines in design projects, directly assisting in project and construction management. [ABSTRACT FROM AUTHOR]

This study aims to establish a mechanistic model of using inherent safety and health concepts to conduct industrial workplace risk reduction strategies during the project planning stage. Accordingly, a dedicated implementation tool termed inherently safer and healthier design model for industrial workplaces (ISHDM‐IW) is developed. First, the safety and health by design checklist is adapted to derive industrial workplace safety and health risk indicators. Then, the risk indicators are rated and weighted using the methods of risk matrix and precedence chart. Subsequently, the risk indicators are aggregated via fuzzy risk representation with the indicators' risk values and weights. Last, the inherent safety and health principles are used to do risk‐based baseline design optimization. The case study demonstrates the capabilities of the proposed ISHDM‐IW to upgrade the workplace design scheme from risk level II to risk level I, thus generating a more satisfactory workplace design alternative. The proposed ISHDM‐IW offers a novel design mechanism of inherent safety and health for industrial workplaces, which can be expected to ensure employees' safety, health, and well‐being with fundamentally better ergonomics of industrial work environments.

Most occupational hazardous agents in workplaces should be evaluated and controlled. Different methods exist for identifying, evaluating and controlling these agents, such as numerical simulation tools. Numerical simulations can help experts to improve occupational health. Due to the importance and abilities of numerical simulations, this study divided occupational hazardous agents into 10 subgroups. These subgroups included air pollution, ventilation, respiratory airways, noise and vibration, lighting, radiation, ergonomics, fire and explosion, risk assessment and personal protective equipment. Recent research studies in each subgroup were then reviewed, and the codes and software used in simulations were determined. The results show that Fluent software and k–ϵ turbulence models are the most used in occupational health studies simulations. Today, different codes and software have been developed for simulation, and we suggest their use in occupational health studies. [ABSTRACT FROM AUTHOR]

Slope failure during or immediately after slope-cutting can cause fatal accidents. This study analyses the characteristics of labour accidents caused by slope failure during slope-cutting in Japan and presents a countermeasure to prevent accidents caused by slope failure, such as the implementation of a slope guideline by MHLW. A case history conducted during slope-cutting and nailing was presented as an example of the application of the slope guideline to ensure safety. Furthermore, monitoring methods were implemented to gain a quantitative understanding of slope deformation. Geological conditions other than those assumed prior to excavation and small collapses attributed to groundwater are indications of landslide risk. The guideline's quick checklist reflects the slope condition or deformation, allowing the client, designer and contractor to discuss and agree on a quick solution to a problem. The case study confirmed the effectiveness of the slope guideline as a tool for sharing information during construction. [ABSTRACT FROM AUTHOR]

Objectives. Although some studies have shown role stressors can lead to unsafe behaviors, it is unclear how role stressors induce delivery riders' unsafe behaviors. We found that delivery riders suffered from tremendous role stressors during the delivery process and had to conduct frequent smartphone interactions. This study aimed to explore the effects of role stressors and smartphone interactions on delivery riders' unsafe behaviors. Methods. First, a questionnaire survey (N = 326) was used to collect data, and correlation and regression analyses were conducted to explore the relationship between role stressors, smartphone interaction frequency and delivery riders' unsafe behaviors. Second, a scenario survey (N = 35) was conducted, and comparative analysis was used to further explore how smartphone interactions affect delivery riders' unsafe behaviors. Results. The questionnaire survey revealed that role stressors, smartphone interaction frequency and delivery riders' unsafe behaviors were positively correlated. In addition, the role stressors forced delivery riders to conduct necessary and unnecessary smartphone interactions. The scenario survey found that smartphone interactions reduced delivery riders' motion speed and motion ability, and increased their psychology, so they had a risk-taking mentality, which led to an increase in unsafe behaviors.

Relevant studies in the fields of fire safety, occupational health and firefighter clothing were analyzed in this study to address the high injury rate among firefighters during fire rescue and the complexity of factors affecting skin burns. The findings indicate that the degree of skin burns in firefighters is primarily influenced by the heat source (heat flux, type), firefighter clothing (fabric, pattern) and the under-clothing air gap (thickness, characteristics). Since skin burns cannot be directly measured, internal skin heat transfer and burn prediction models are commonly employed to assess the impact of external factors on skin burns. These models can predict the safe working distance or time for firefighters. Investigating the influencing factors and prediction models of skin burns among firefighters holds significant value in enhancing operating procedures, optimizing firefighter clothing design and effectively preventing skin burns.

Background: Patient safety (PS) is a core competency for registered nurses. However, there is a gap between the PS competence of nursing students and their clinical experience in PS. This study explored the effect of PS competence levels on the occurrence of adverse events (AEs) among nursing master's students in China. Methods: A sequential mixed methods design was used, with a purposive sample across seven colleges. A total of 327 graduate nursing students, aged 22 to 38, participated in the survey, and 15 participated in qualitative interviews. The Health Professional Education in Patient Safety Survey (H-PEPSS) assessed the students' competence levels in PS. The respondents also reported any AEs that they had been involved in over the past year. Results: A total of 78 AEs occurred in the past year, with 17.7% of the participants involved 1 to 3 AEs. The most common AEs were medication administration errors (30.77%) and improper use of medical equipment/supplies (28.20%). Students acquired more competencies from the clinical setting than from the classroom setting. Three competencies learned from classroom settings were associated with clinical AEs: low clinical safety skills [OR = 0.61], inappropriate identify, response to and disclosing AE and close calls [OR = 0.454], and low confidence in working in teams with other health professionals [OR = 2.168]. Qualitative data analysis revealed five themes: recognizing AEs, reducing harm by addressing immediate risks to patients and others involved, promoting safe medication and clinical practice, managing members' authority and team dynamics, and dealing with inter-professional conflict. Conclusions: The quantitative and qualitative data align, supporting the enhancement of students' PS competence. [ABSTRACT FROM AUTHOR]

Background The public order and safety (POS) sector remains susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreaks, as workplace attendance is typically compulsory and close physical contact is often needed. Here, we report on a SARS-CoV-2 outbreak with an attack rate of 39% (9/23), which occurred between 19 and 29 June 2021 among a cohort of new POS recruits participating in a mandatory 18-week training programme in England. Methods The COVID-OUT (COVID-19 Outbreak investigation to Understand Transmission) study team undertook a multidisciplinary outbreak investigation, including viral surface sampling, workplace environmental assessment, participant viral and antibody testing, and questionnaires, at the two associated training facilities between 5 July and 24 August 2021. Results Environmental factors, such as ventilation, were deemed inadequate in some areas of the workplace, with carbon dioxide (CO2) levels exceeding 1,500 ppm on multiple occasions within naturally ventilated classrooms. Activities during safety training required close contact, with some necessitating physical contact, physical exertion, and shouting. Furthermore, most participants reported having physical contact with colleagues (67%) and more than one close work contact daily (97%). Conclusions Our investigation suggests that site- and activity-specific factors likely contributed to the transmission risks within the POS trainee cohort. Potential interventions for mitigating SARS-CoV-2 transmission in this POS training context could include implementing regular rapid lateral flow testing, optimizing natural ventilation, using portable air cleaning devices in classrooms, and expanding use of well-fitted FFP2/FFP3 respirators during activities where prolonged close physical contact is required.

BACKGROUND: Mercury (Hg) is a toxic heavy metal with multiple uses in various medical devices. Hg is used in dentistry as a restorative material. Such use creates significant exposure to dental practitioners. Hence, it is important to assess the risk created by Hg use in healthcare. OBJECTIVE: To quantify airborne Hg vapour exposure and Hg levels in dental healthcare workers, and determine the association of various symptoms and diseases to Hg exposure. METHODS: Air monitoring of Hg vapours were conducted in dental clinics and amalgam rooms. Urine samples were collected from occupationally exposed dental healthcare workers and urine Hg levels were measured. A cross-sectional health survey was conducted in 23 healthcare units of Delhi to determine an association between Hg exposure and various health effects. RESULTS: Hg vapour concentration ranged from 0.96μg/m3 to 15μg/m3, the highest concentration was recorded in the amalgam room (15μg/m3). Urine Hg levels in healthcare workers (0.51±0.17μg/L) were higher than the control (0.29±0.05μg/L). A cross-sectional health survey revealed a significant prevalence of confusion, forgetfulness, muscle spasm, and tremors by the respondents. CONCLUSION: Hg concentration in dental clinics may hover above the prescribed safe levels posing a definitive health risk to healthcare workers. Urinary Hg measurements did not reveal an excess of body burden except in one case. Since Hg bio accumulates, it is probable as these workers grow older, they may end up with a higher body burden of Hg that may lead to a variety of adverse health outcomes. [ABSTRACT FROM AUTHOR]

Background: Nurse burnout is a widespread issue in the health care industry, jeopardizing the well-being of both health care professionals and the patients they serve, manifesting as an intense sense of exhaustion, depersonalization, and a diminished sense of personal achievement. Method: In nursing, professionals are exposed to an extraordinary array of challenges and demands that increase their likelihood of experiencing burnout and resulting mental health issues. Although burnout has been aggressively discussed and studied in recent years, strategies for preventing and mitigating burnout have been underreported. Results: This article highlights leading causes of burnout, delves into its alarming prevalence, and underscores the critical need for comprehensive strategies to address and prevent it. Conclusion: This article highlights several initiatives established by a resilience program at a college of nursing that can be implemented within health care systems to directly address both individual and organizational burnout.

Background. Nurse protection is a multifaceted concept that has become increasingly relevant in recent years. Despite its importance in effectively managing pandemics, there is still a gap in knowledge about how nurses achieve protection in hospitals. Objective. To describe the process of seeking protection among nurses during the COVID‐19 pandemic. Methods. A grounded theory approach from 2020 to 2022, employing purposive and theoretical sampling. Face‐to‐face and online interviews were conducted with 25 participants, resulting in 29 interviews. Data analysis was carried out using Corbin and Strauss's method (2015). Results. The analysis revealed that nurses encountered numerous obstacles related to patients, nurses themselves, organizations, and the passage of time during the COVID‐19 pandemic. These challenges were intertwined with three key concepts: transformations, inequalities, and emotional challenges, highlighting the multifaceted nature of nurses' protection concerns. In response, nurses employed a protective strategy bolstered by catalysts to address these challenges. This strategy encompassed both optimistic outlooks ("Bright horizon") and somber reflections ("Unpleasant reflection"). Ultimately, seeking protection in the heart of the storm emerged as the core concept, representing the multifaceted process through which nurses navigate and seek protection amidst the unique challenges posed by the pandemic. Conclusions. This study presents a comprehensive theory that explicitly explains the multifaceted process of seeking protection among hospital‐employed nurses during a pandemic. The theory captures the interconnectedness of challenges faced by nurses and the protective strategies they employ while acknowledging the nuanced balance between hopeful prospects and sobering reflections. Implications for Nursing Management. Policymakers, managers, and educators can utilize the findings to improve nursing management and support systems. By increasing awareness, addressing challenges, and providing robust support, they can enhance the well‐being and effectiveness of nurses during healthcare crises, ultimately improving patient care quality.

Background: Global nursing shortages necessitate the identification of mitigatable factors that may reduce nursing absence and turnover. Fatigue has been shown to be associated with these issues. This study aimed to identify factors leading to development of or recovery from excessive fatigue in nurses as these can offer actionable avenues for protecting nurses against fatigue or supporting fatigue recovery. Methods: A longitudinal study among nurses randomly sampled from the Norwegian Nurse's Organization. The Chalder Fatigue Questionnaire measured fatigue. Dichotomized scoring was used, with scores ≥ 4 considered excessive fatigue. The study included questions on shift work schedules, psychosocial work characteristics, sleep, body mass index, physical activity, caffeine, alcohol, mental health, etc. Two sets of logistic regression analysis were conducted (one for development of and one for recovery from excessive fatigue), evaluating how changes in work, lifestyle and health between baseline (2015) and follow-up (2018) affected first, odds of development of excessive fatigue and second, odds of recovery from excessive fatigue. Results: Among 1,311 included nurses, 21.6% maintained, 13.3% developed, and 18.0% recovered from excessive fatigue (2015–2018). Within work characteristics, increased psychological work demands were associated with development of excessive fatigue OR = 1.77 (CI = 1.11–2.82). Several work characteristics were associated with recovery from excessive fatigue, including decreased decision latitude (OR = 0.39; CI = 0.19–0.82) and increased coworker support (OR = 1.90; CI = 1.11–3.24). Shift work variables were not associated with fatigue outcomes. Amongst lifestyle factors, changes in sleep duration, obesity, and exercise were significant. Notably, developing inappropriate sleep duration (OR = 2.84; CI = 1.47–5.48) increased odds of developing excessive fatigue, while maintaining inappropriate sleep duration (< 6 h or > 8 h) (OR = 0.19; CI = 0.54–0.65) decreased odds of recovering. All assessed health conditions (depression, anxiety, insomnia, and shift work disorder) were related to development of (ORs 2.10–8.07) or recovery from (ORs 0.10–0.50) excessive fatigue. Depression, for example, increased odds of development of (OR = 8.07; CI = 2.35–27.66) and decreased odds of recovery (OR = 0.10; CI = 0.04–0.26) from excessive fatigue. Conclusions: Changes in lifestyle factors, health conditions, and psychosocial work factors were associated with development of and recovery from excessive fatigue. Sleep and psychosocial work factors played important roles. We found no relationship with shift work schedules. [ABSTRACT FROM AUTHOR]

The objective was to study the interaction of the components of a complex liquid mixture on the permeation parameters of its constituents. A firearm cleaning solvent, Hoppes No. 9 Gun Bore Cleaner, was selected to challenge two varieties of disposable nitrile gloves, the thinnest (Kimberly-Clark Lavender) and thickest (Kimberly-Clark Blue), using the closed-loop ASTM F739 cell without recirculation and n-decane collection followed by quantitation of the permeated compounds using capillary gas chromatography–mass spectrometry. The thicker Blue glove resisted the permeation of Hoppe's relative to the thinner Lavender glove as shown by 3.2 times more mass permeated by the Lavender glove at 60 min despite the same standardized breakthrough times (7.5 ± 2.5 min). The kerosene fraction permeated faster at a much higher rate than expected. The Kimberly-Clark disposable nitrile glove chemical resistance guide lists a breakthrough time for kerosene of 82 min for Sterling disposable nitrile glove material. However, for Hoppe's the kerosene components appeared at the standardized breakthrough time. Mixture components that were reported by the glove manufacturer to quickly permeate the disposable nitrile material, such as ethanol, did not permeate at a rate slower than expected, indicative of a possible carrier function. A semiquantitative risk assessment confirmed the unacceptability of both gloves. Persons using personal protective equipment, such as gloves, may not be afforded the expected resistance to chemical permeation when chemicals are in a suitable mixture, hence enhancing the risk of exposure. More research is needed to produce better glove testing measures to ensure the safety of workers. [ABSTRACT FROM AUTHOR]

This study examined factors related to perceived health risks in confined spaces (PCSHR) and their correlation with the mental workload among farmers managing agricultural wells in northern Thailand. A cross-sectional, multi-stage sample of 356 farmers was selected from four rural districts' agricultural areas. Data were collected through interviews conducted from August to December 2022, using a self-administered structured questionnaire. The five-part questionnaire gathered demographic data, information on experiences and operations in agricultural wells, knowledge of confined spaces, PCSHR, and the six-dimension NASA Task Load Index (TLX) mental workload. Linear regression and multi-variable analyses were used to investigate factors associated with PCSHR, while Pearson correlations tested the association between PCSHR and mental workload variables. Most farmers were male (92.4%), worked in wells to install pumping systems (81.7%) and maintain equipment (73.3%), averaging 3.80 times per year, with an average duration of 25.81 minutes. Physical symptoms reported included difficulty breathing (72.8%), feeling swelteringly hot (55.9%), and sweating excessively (27.8%), as well as accidents such as being struck by falling soil or objects (20.2%), and falling into the well while climbing down (14.9%). Farmers' perceived risk scores were high when working while physically exhausted or unprepared and when assisting an unconscious worker without knowing the gas concentration. In addition, the maximal mental workload scores were mental demand and effort subscale. Factors significantly associated with PCSHR (adj.R2 = 60.6%, p <.05) encompassed education higher than lower secondary level, current alcohol consumption, smaller well width, assisted operations, number of physical symptoms experienced, absence of environmental accidents, and confined space knowledge, while increased PCSHR was positively associated with mental workload (Overall r = 0.711, p <.01). Comprehensive education about potential hazards can improve farmers' risk perception, potentially reducing mental workload and preventing fatal accidents. Field studies are recommended to develop community-specific work protocols and accurate measuring instruments suitable for rural settings are needed. [ABSTRACT FROM AUTHOR]

This study looks into the effectiveness of the authorisation procedure as a regulatory instrument within the framework of the European REACH regulation. It highlights its impact on enhancing occupational safety and health for both applicants and companies utilising the substances. This procedure encompasses manufacturers, importers, and downstream users of substances, as well as representatives of foreign manufacturers who are also eligible to seek authorisation. When applying for authorisation, the ECHA Risk Assessment Committee (RAC) assesses the risks associated with the intended uses of the substance, including the appropriateness and effectiveness of the Occupational Conditions (OCs) and Risk Management Measures (RMMs) described in the application and the risks posed by potential alternatives. If the RAC determines that the OCs/RMMs are inadequate for managing or controlling the risk, or if the measures to protect workers are deemed insufficient, it may recommend additional measures to enhance occupational safety and health or environmental protection. The 398 processed Applications for Authorisation (AfA) that have been submitted to date were examined to determine these recommended measures, categorised as Conditions for use, Monitoring arrangements, and Recommendations for Review Reports. Overall, a significant improvement concerning occupational safety and health seems necessary, as indicated by the large number of measures recommended by the ECHA Committee for Risk Assessment (RAC) and ECHA Committee for Socio-economic Analysis (SEAC) or supplemented by the European Commission. In addition to the proposed measures, a short assessment provided by the committees as to whether the operational conditions and risk management measures are adequate in controlling the risks is also included in the study.

Burnout is a state of emotional and physical depletion. Its occurrence among critical care nurses (CCNs) is a concept that has gained traction yet remains an issue with global consequences. Nurses are especially vulnerable to burnout due to the persistent stressors they are exposed to, which include the general work environment, biological factors, and emerging changes caused by COVID-19. This study aims to assess the severity of burnout among CCNs during the COVID-19 pandemic and its associated factors. A descriptive cross-sectional questionnaire was used in this study to measure the estimated burnout rate among CCNs in Palestine and establish associations with potential factors. Maslach Burnout Inventory questionnaire was used for the task. The results showed out of the 173 participants, more than 35% reported severe overall burnout. Per burnout domains, it was found that around 70% of participants suffered from low personal accomplishment, while 59.5% had severe levels of depersonalization, and finally, more than 65% of critical nurses had severe emotional exhaustion. Out of the various variables tested, gender, age, type of hospital, PPE, and fear of transmission were found to be associated with overall burnout. CCNs in Palestine were found to be severely burned out and should be dealt with before getting out of hand. The research found variables related to burnout contributed to burnout. Recommendations for further studies and prioritization should be made. [ABSTRACT FROM AUTHOR]

Construction projects are a field of work with a high risk of work accidents. CV XYZ, a construction service company, often experiences work accidents on highway projects. These work accidents are caused by human negligence, substandard materials, and inadequate occupational safety and health (OSH) implementation methods. Based on these problems, this study aims to design work accident risk control at CV XYZ to reduce and prevent work accidents on road construction projects. The design of occupational safety and health (OSH) control is carried out by conducting risk analysis on road construction project activities through the HIRADC (Hazard Identification, Risk Assessment, and Determining Control) approach and designing improvements to the occupational safety and health (OSH) control business process. The design of OSH risk control created in this study aims to implement risk control and reduce the risk of work accidents in the company. [ABSTRACT FROM AUTHOR]

BACKGROUND: Climate change and global warming are emerging as new challenges worldwide. The World Meteorological Organization has reported that the temperature is expected to rise by an average of 1.2°C between 2021–2025. This increase in temperature will expose more and more workers to extreme heat. OBJECTIVE: This study aimed to explore the possibility of using thermoelectric coolers for cooling the water circulation circuit of a cooling belt, which can be used for extended periods in high-temperature environments. METHODS: A cooling belt was designed using thermoelectric coolers (TEC) and two blowers. The TECs were equipped with heat sinks and heat exchange block made of aluminum at hot and cold sides to exchange heat effectively. RESULTS: The experiment was conducted under actual environmental temperature conditions during three different time periods, with mean temperatures of 31, 48, and 41°C. The mean temperature of the belt section was recorded as 20.73, 24.52, and 21.38°C, respectively. The maximum average difference between the inlet air temperature and the inside cooling belt temperature was 40.45°C. CONCLUSION: The experiment revealed that the cooling performance of the designed prototype remained within an acceptable range (18°C) despite the increase in ambient temperature. Moreover, the cooling system can be utilized in high-heat environments to reduce thermal stress. [ABSTRACT FROM AUTHOR]

As a critical activity in occupational risk management, the occupational health and safety risk assessment (OHSRA) aims at assessing occupational hazards in the workplace and prioritizing them to ensure employees' safety and reduce occupational risk to an acceptable level. In this paper, we develop a new integrated OHSRA model for the risk evaluation and prioritization of occupational hazards based on probabilistic linguistic information and social network consensus analysis. The probabilistic linguistic term sets are applied to handle the hesitant risk evaluations of occupational hazards provided by experts. A combinative distance-based assessment technique is introduced for determining the risk priority of the identified occupational hazards. Additionally, the social network consensus analysis with minimum adjustment distance is used to help individual experts reach consensus. Finally, a healthcare case study is implemented for illustrating the developed OHSRA model and its effectiveness is validated with a sensitivity analysis and a comparative analysis.

Purpose: Few studies have investigated how high-risk domestic and family violence perpetrators threaten staff, how organizations support staff, and whether communities of practice improve service coordination and the safety of workers and the families they serve. The purpose of this article is to explore worker safety among practitioners involved in high-risk domestic and family violence and child protection cases. Methods: Participatory action research methodology was used to investigate and develop cross-sectoral workforce capacity at the intersection of domestic and family violence and child protection practice. This study, based in Queensland, Australia, drew on a subset of data from a larger study of communities of practice. Participants were 15 senior practitioners and team leaders from child protection, women's and men's domestic violence services, family support, and justice services. Data were collected in 2018. Data sources included ethnographic notes and transcripts from communities of practice and focus groups. Data were qualitatively analyzed. Results: Five key themes emerged in the findings: risks to workers associated with the physical environment; advances in perpetrators' use of technology; failings in police responses and the judicial system; a parallel process between workers' and women's responses to threats to their physical and psychological safety; and strategies for improving safety when working with high risk perpetrators of domestic and family violence. Conclusions: Improving the physical and psychological safety of workers in high-risk domestic and family violence and child protection cases requires moving beyond intra-organizational policies and practices and addressing the inter-sectoral and systemic factors that increase risk and reduce safety for child and adult victim/survivors and workers.

As vehicles with high accident and casualty rates within the road transportation system, engineering vehicles have been receiving much attention and emphasis in terms of safety. Accurate analyses and evaluations of risk factors in vehicle operation are imperative for enhancing the management level of engineering vehicles. This study explores the differences between various types of drivers by analyzing the driving characteristics of professional drivers. The evaluation index system is developed and quantified by integrating factors related to engineering vehicle drivers, road environment, and industry management. Additionally, the risk assessment model is developed using the error backpropagation algorithm. The optimal model is determined by comparing the number of nodes in different hidden layers, the activation function, and regularization optimization. The prediction accuracy of this model's coefficient of determination is 0.912, indicating that the model has validity. This study is conducive to improving the safety level of engineering vehicle operation in order to reduce the rate of vehicle traffic accidents, the severity of accidents, and the consequences of losses. It also has practical application value in safeguarding social security. [ABSTRACT FROM AUTHOR]

After 18 years since the legislative changes in the field of safety and health at work introduced the obligation to assess occupational risks at all workplaces, we note that the indigenous method of the National Research and Development Institute for Labor Protection in Bucharest was quasi-generalized in applicability. Starting from this practical reality, this paper aims to offer a more synthetic and pragmatic version of the application of the method for more complex jobs/activities, in which several socio-professional categories of workers are involved, by structural optimization of the procedure for the implementation of the specific stages and tools, in order to increase the effectiveness of the assessment of occupational injury and illness risks. This finality is achieved through a case study applied to a construction activity carried out within an important hydro-technical project. The main advantages of the approach proposed by the authors are summarized. [ABSTRACT FROM AUTHOR]

Construction operations, particularly concrete formwork, pose significant risks of musculoskeletal disorders (MSDs) to workers. Previous studies have examined the MSDs associated with conventional job-built formwork. In light of the growing popularity of modern ready-made formwork systems, and the claim that such systems reduce MSDs, it is imperative that researchers characterize the activities associated with the use of these systems and offer empirical insight into their relationship with MSDs. In response to this need, this study aims to assess and compare MSD risks related to different modern formwork systems. Specifically, the Rapid Entire Body Assessment (REBA), a method for full-body postural ergonomic risk assessment, was used to study the ergonomic hazards of form workers during the installation and removal of horizontal modular and prefabricated or engineered formwork systems. The findings indicate that most formwork tasks and activities subject workers to medium to high MSD risks, necessitating preventive actions or imminent preventive actions. Modular formwork systems may subject workers to fewer hazardous ergonomic working conditions compared with prefabricated or engineered formwork systems. The findings provide an improved understanding of formwork activities and the MSD risks associated with ready-made formwork system construction, and provide a valuable resource for formwork designers and constructors dedicated to improving worker health and safety in formwork construction.

Podologists are exposed to many occupational hazards, including volatile organic compounds (VOCs) from insole manufacturing and noise/vibration during nail or tissue grinding. In this study, VOCs, noise, and vibration were measured in five podiatry clinics and three offices. Questionnaires were administered to 23 podologists and 19 office workers to inquire about their pain, ocular, skin and respiratory complaints. The results showed that the podologists' exposure to the total VOC concentrations was approximately twice as high as that of the office workers. The podologists' complaints regarding pain were found to be correlated with ambient noise and hand-arm vibration levels. Ocular, skin, and respiratory complaints were also found to be correlated with total VOC concentrations. These results suggest that VOCs, noise and vibration in the working environment may impair podologists' health and that they have an intensifying effect on each other, increasing the severity of health issues.

Objective: Risky exposure of healthcare workers to blood and body fluids is one of the most critical global issues. This study aimed to determine the frequency, conditions, and interventions of risky contacts and provide guidance on infection control measures to enhance occupational safety. Methods: Healthcare workers' risky contact with blood and body fluids was investigated from January 2013 to December 2022. The contact tracking forms for blood and body fluid exposures in the Infection Control Committee (ICC) were retrospectively examined. Furthermore, the effects of the regulatory activities implemented by the ICC on the problems detected during the active surveillance of risky contacts and the effects of the COVID-19 pandemic during the monitoring process were evaluated. Results: During the ten-year follow-up period, a total of 700 risky contacts were identified in 625 healthcare workers, with 643 (91.9%) resulting from needlestick and sharp injuries and 57 (8.1%) from skin and mucosal contact. Of the risky contacts, 262 (37.4%) occurred in internal medicine units, 171 (24.4%) in surgical units, and 112 (16%) in the emergency department, making these the most common locations for risky contacts. The most frequently reported occupational groups were, respectively, 267 (38%) interns, 185 (26%) nurses, and 173 (25%) cleaning staff. When evaluating how risky contacts occurred, it was determined that 215 (30.7%) occurred during invasive procedures, 108 (15.4%) while recapping the needle, and 528 (75%) resulted from needlestick injuries. It was determined that 13% of risky contacts applied to the ICC after 72 hours, and 79% used appropriate personal protective equipment (PPE). The highest rate of PPE usage, at 93%, was observed in 2020, when the COVID-19 pandemic began. In 2013, it was observed that the most common risky contacts occurred during waste collection, and over the years, injuries during waste collection decreased with training. Although the source was unknown in 32% of risky contacts, a decrease in the rate of risky contacts with unknown sources was achieved over time. Out of 478 risky contacts with known sources, 71 (14.9%) occurred with patients infected with hepatitis B, 35 (7.3%) with hepatitis C, and seven (1.5%) with HIV. Ninety-six per cent of the nurses were exposed to risky contacts, 93% of interns, 87% of doctors, 56% of cleaning personnel, and 84% of other healthcare workers were immune to hepatitis B. After a one-year follow-up period with post-exposure prophylaxis, no healthcare worker developed hepatitis B or HIV infection, while one person was found to be anti-HCV positive. Conclusion: Needlestick-sharp object injuries remain a significant issue. All healthcare institutions must regularly monitor risky contacts with blood and bodily fluids, identify problems, develop targeted infection control measures, and plan periodic training.

The aim of this study was to explore occupational safety in pregnant Croatian healthcare workers (HCWs) during the coronavirus disease 2019 (COVID-19) pandemic. To this end we composed an anonymous questionnaire that included pregnancy data, risk assessment and mitigation, and workplace intervention and distributed it to HCWs through social media of their groups and associations. The study includes a total of 173 respondents (71.1 % physicians, 19.7 % nurses, 9.2 % other HCWs) diagnosed with pregnancy in 2020 and 2021. Employers were notified about HCWs' pregnancy at the eighth (IQR 7.0–11.0) week of pregnancy, which delayed workplace risk assessment and mitigation beyond the first trimester. Only 19.6 % of the participants had the risk assessed and mitigated, mostly on their own initiative (76.5 %). After notifying employers about pregnancy, 37.0 % of participants opted for temporary work incapacity (TWI) due to "pregnancy complications" despite healthy pregnancy, 16.8 % were granted a pregnant worker's paid leave at the expense of the employer, while 5.8 % continued to work at the same workplace. Nurses used the TWI benefit more frequently than physicians (58.8 % vs 30.1 %, P=0.004). Our findings suggest that occupational safety of pregnant HCWs in Croatia lacks clear-cut and transparent strategies to protect pregnant HCWs, forcing them to misuse the healthcare system.

Objectives This study: (i) quantified the typical noise levels in an Irish neonatal intensive care unit (NICU) and compared the values to recommendations by the American Academy of Paediatrics (AAP) and the European Standards for Care for Newborn Health (EFCNI) and to occupational exposure limit value and exposure action values; and (ii) qualified the perception of noise levels and the sources of noise across the various stakeholders within a typical NICU. Methods A noise survey was conducted in an Irish NICU. Observations identified practices and behaviours in the NICU that potentially had an impact on noise levels. Noise levels were compared to occupational exposure limits and AAP and EFCNI standards. A noise perception survey was conducted to identify noise sources and awareness of noise levels in the NICU. Results were analysed using SPSS Statistics to determine statistical significance. Results Noise levels recorded were consistent with previous similar studies and in all cases, the average noise levels recorded exceeded the 45 dBA as recommended by the AAP and EFCNI. There was a statistically significant difference (P < 0.01) between noise levels recorded on the day shift compared to the night shift. The perception of noise levels reported by nurses versus parents was found to be statistically significant (P = 0.001). 38.3% of all respondents reported having received no information or training with regard to noise in the NICU. There was a statistically significant difference in the perception of who is most likely to be affected by noise in the NICU, with nurses reporting those most likely to be affected by noise were patients, and parents reporting those most likely to be affected were staff (P = 0.003). Conclusions This study supports the hypothesis that noise levels within the NICU are of concern and require regular assessment and monitoring. Training and awareness programmes are an important component to ensuring all persons in the NICU recognise their potential impact on noise levels in the NICU and in reducing the risk for patients and staff.

Employment linked with social venues has long been described as permissive environments for excessive drinking, disruptive/aggressive behaviors, and overt sexual behaviors, which are known risk factors for HIV. Yet, our understanding of the extent to which workers in such high-risk work settings cope with the various risks therein is still limited. This study explored the coping strategies employed by workers at social venues. We interviewed 47 workers at 22 social venues through small group discussions (15) and in-depth interviews (10) in 2021 in Rakai district, Uganda. All discussions were audiorecorded and transcribed verbatim before analysis. Data were analyzed using thematic content analysis. We found two main categories of coping strategies used by workers: acceptance of sexual risks and keeping safe. Acceptance of risks such as transactional sex was the most used strategy, hence highlighting negative coping. This calls for interventions for improving workers' coping efficiency and adjustment as well as interventions ameliorating the conditions underpinning increased risk of HIV at the venues.

In this research, the levels of safety, health, and environmental risks in a building stone processing company (BSPC) have been identified using the integrated approach of the EFMEA (Environmental Failure Mode and Effects Analysis) and the William Fine method, along with the TOPSIS technique for prioritizing organizational safety layers, examining potential incidents, and enhancing organizational efficiency. To achieve this, data and risk assessment information were first collected and evaluated, and then, with the formation of an expert task force, brainstorming sessions were held to identify and analyze environmental risks in the production process using the EFMEA technique. Additionally, with the assistance of the William Fine method, safety and health risks in the production process were identified and examined. In the next step, the costs of corrective actions were calculated, and the results obtained from the tables of both EFMEA and William Fine techniques were combined, and decisions were made regarding risks with high and very high levels. Subsequently, using TOPSIS, protective layers were prioritized based on two criteria: cost and time. Following the risk assessment using the EFMEA method, four risks were classified as high-risk, nine risks as medium-risk, and two risks as low-risk. Subsequently, employing the William Fine technique, a total of 41 hazards were evaluated across five worksheets. 5% of the hazards were categorized as very high-risk, 19% as high-risk, 27% as medium-risk, and 49% of the evaluated hazards were classified as low-risk. Ultimately, the results obtained from the integration of the William Fine and EFMEA techniques categorized two risks as very high-risk, 12 risks as high-risk, 20 risks as medium-risk, and 22 risks as low-risk. Furthermore, working at heights was selected as one of the risks with high-risk, and protective layers and control measures were proposed and examined. The use of helmets, shoes, harnesses, and the establishment of a safety platform, considering both time and cost criteria, is the first priority for controlling risks in working at heights activity.

Over 50% of nuclear power plants (NPPs) worldwide have operated for over three decades, leading to a surge in decommissioning projects. This study addresses the gap in current guidelines by analyzing risks in nuclear decommissioning. Using the fuzzy-AHP technique, tasks within dismantling radioactive concrete structures are prioritized. Findings reveal structural and human-related risks across five main cutting tasks. Collision emerges as a significant concern, particularly during wire saw installation and concrete block hoisting hole creation. Subcategory risk priorities highlight variations in risk across tasks, with jamming, falling, and falling objects identified as top concerns during wire saw transportation. This study emphasizes the importance of comprehensive risk assessment in enhancing safety during decommissioning. It underscores the need to consider both physical risks and risks to personnel throughout the process. By prioritizing safety, stakeholders can ensure worker safety and operational efficiency while minimizing hazards. This research contributes to standardized safety protocols for nuclear decommissioning worldwide, aligning with sustainable energy practices. The outcomes offer practical insights for safety manual development and decision-making processes. This study represents progress in ensuring safety during nuclear decommissioning, paving the way for further refinement of safety protocols and guidelines tailored to decommissioning sites.

BACKGROUND: Occupational accidents in the plumbing activity in the construction sector in developing countries have high rates of work absenteeism. The productivity of enterprises is heavily influenced by it. OBJECTIVE: To propose a model based on the Plan, Do, Check, and Act cycle and data mining for the prevention of occupational accidents in the plumbing activity in the construction sector. METHODS: This cross-sectional study was administered on a total of 200 male technical workers in plumbing. It considers biological, biomechanical, chemical, and, physical risk factors. Three data mining algorithms were compared: Logistic Regression, Naive Bayes, and Decision Trees, classifying the occurrences occupational accident. The model was validated considering 20% of the data collected, maintaining the same proportion between accidents and non-accidents. The model was applied to data collected from the last 17 years of occupational accidents in the plumbing activity in a Colombian construction company. RESULTS: The results showed that, in 90.5% of the cases, the decision tree classifier (J48) correctly identified the possible cases of occupational accidents with the biological, chemical, and, biomechanical, risk factors training variables applied in the model. CONCLUSION: The results of this study are promising in that the model is efficient in predicting the occurrence of an occupational accident in the plumbing activity in the construction sector. For the accidents identified and the associated causes, a plan of measures to mitigate the risk of occupational accidents is proposed. [ABSTRACT FROM AUTHOR]

Objectives. Improvement of the professionalization level for the new generation of construction workers (NGCWs) is critical to upgrade the construction industry. It also provides a new approach to reduce their unsafe behaviour. The purpose of this study is to analyse the correction mechanism of the professionalization level on NGCWs' unsafe behaviour. We examined the mediating role of work–family conflict and job burnout on impacting NGCWs' unsafe behaviour. The moderation effect of the NGCWs' perceived organizational support was also examined. Methods. The cross-sectional study was conducted based on structural equation modelling, confirmatory factor analysis and regression analysis with a sample of 496 NGCWs in China. Results. The professionalization level can effectively correct NGCWs' unsafe behaviour. Job burnout can independently mediate the relationship between professionalization level and unsafe behaviour and act as a serial mediator for work–family conflict. Moreover, the high level of perceived organizational support will effectively suppress the effect of work–family conflict on job burnout. Conclusions. Improving the professionalization level is an effective way to correct NGCWs' unsafe behaviour. Moreover, management should help the NGCWs balance work and family, to alleviate burnout. Additionally, it is suggested that management should ensure the NGCWs perceive the organizational support. [ABSTRACT FROM AUTHOR]

Objectives. It is prescribed to determine blue-light hazard (BLH) weighted radiances, $ {L_\textrm{B}} $ L B , for an assessment of spotlights with an angular subtense $ \alpha \ge 11{\mkern 1mu} \,\textrm{mrad} $ α ≥ 11 mrad . The BLH weighted irradiance, $ {E_\textrm{B}} $ E B , can be used alternatively for smaller sources. Appropriate instruments are not common among persons commissioned with risk assessment (RA), and especially $ {L_\textrm{B}} $ L B measurements may be challenging. Therefore, a practical BLH RA approach is proposed that is based on illuminance, $ {E_\textrm{v}} $ E v , pre-calculated blackbody BLH efficacies of luminous radiation, $ K_{\textrm{B,v}}^{\textrm{Planck}} $ K B,v Planck , and solid angle considerations. Methods. The practicality of this method was examined and compared against other RA approaches. Results. To ensure comparability of the applied instruments, measurements were performed close to a radiance standard, showing deviations within the lamp's expanded uncertainties ( $ \lt 4{\mkern 1mu} \% $ < 4 %), whereas the deviations were $ \pm 15\% $ ± 15 % for longer distances. Focusing on a complex light-emitting diode (LED) spotlight, all detected values could be converted to $ {L_\textrm{B}} $ L B by means of the RA methods within $ \pm 20\% $ ± 20 %. Two field tests with several spotlights yielded maximum permissible exposure durations (MPED) obtained from the different RA approaches that agreed among each other within uncertainties largely below $ \pm 30\% $ ± 30 %. Conclusion. The general practicality of the proposed $ {E_\textrm{v}} $ E v method can be concluded for a workplace BLH RA of white-light sources. [ABSTRACT FROM AUTHOR]

Background: Efforts to increase capacity for oncology treatment in the author's Chemotherapy Day Unit, while allowing staff to treat more patients and offer more flexibility to patients, increased strain on the Aseptic Pharmacy at the author's Trust. Therefore, the possibility of nurse-led drug preparation was explored. Aims: Nurse-led monoclonal antibody (MAb) preparation was piloted to investigate whether a reduction in reliance on Aseptic Pharmacy could co-exist with maintaining optimal treatment capacity. The effectiveness of a closed system transfer device (CSTD) to protect nurses against drug exposure was also explored. Methods: A risk assessment for MAbs considered for nurse-led preparation was created, alongside a procedure for the safe handling of systemic anti-cancer therapy (SACT) with the use of a CSTD. Findings: The pilot resulted in an 89% reduction in the time patients had to wait for MAbs to be prepared. Seven oncology drugs were included in the new procedure without increasing the risk of exposure for nurses. Conclusion: The pilot successfully reduced demand on Aseptic Pharmacy while enabling efficient capacity use on the Chemotherapy Day Unit. The use of the CSTD minimised the risk of nurse exposure to SACT. [ABSTRACT FROM AUTHOR]

Residents of long-term care facilities are particularly vulnerable to communicable diseases. Low-cost interventions to increase air exchange rates (AERs) may be useful in reducing the transmission of airborne communicable diseases between long-term care residents and staff. In this study, carbon dioxide gas was used as a tracer to evaluate the AER associated with the implementation of low-cost ventilation interventions. Under baseline conditions with the room's door closed, the mean AER was 0.67 ACH; while baseline conditions with the door open had a significantly higher mean AER of 3.87 ACH (p < 0.001). Subsequently opening a window with the door open increased mean AER by 1.49 ACH (p = 0.012) and adding a fan in the window further increased mean AER by 1.87 ACH (p < 0.001). Regression analyses indicated that the flow rate of air entering through the window, both passively and through the use of a fan, was significantly associated with an increase in AER (p < 0.001). These results indicate that low-cost interventions that pull outside air into resident rooms were effective in improving the air exchange rates in these facilities. While implementation of these interventions is dependent on facility rules and isolation requirements of residents with airborne communicable diseases, these interventions remain viable options for long-term care facilities to improve resident room ventilation without requiring costly ventilation system upgrades.

Over the past 15 years, there have been numerous fatalities related to working with animal slurry. Working with cattle slurry releases toxic gases, in particular, hydrogen sulphide (H2S), which can cause acute central nervous system toxicity, breathing difficulties, and death if exposed to high concentrations. Real-time measurements of H2S gas were taken over distance and time, during the stirring of cattle slurry on farms. Gas was measured at eight slurry stores with differing typical configurations of indoor or outdoor stores and with or without slatted flooring. Highest H2S gas levels were measured from indoor stores under slatted floors, and generally at positions closest to the stirrer or the point of maximum stirring, with levels decreasing with distance from source. Most of the data indicate H2S gas levels increase very rapidly after stirring starts, and mostly decline to baseline levels within 30 min post start of stirring. There were, however, circumstances where gas levels remained high and only started to decline once the stirrer had stopped. H2S gas levels at all farms, at all positions measured were consistently below 10 ppm within 30 min of the stirrer being stopped. The current data highlight areas of the farm and ways of working that have the potential for workers and others to be at risk of exposure to toxic slurry gases. The area should be left to ventilate naturally for at least 30 min after the stirrer has been stopped before re-entering buildings. Influencing the design of stirring equipment and future slurry stores would likely reduce the risk of worker exposure to slurry gases. [ABSTRACT FROM AUTHOR]

Background This study was conducted as an effort to develop a Korean construction job exposure matrix (KoConJEM) based on 60 occupations recently consolidated by the construction workers mutual aid association for use by the construction industry. Methods The probability, intensity, and prevalence of exposure to 26 hazardous agents for 60 consolidated occupations were evaluated as binary (Yes/No) or four categories (1 to 4) by 30 industrial hygiene experts. The score for risk was calculated by multiplying the exposure intensity by the prevalence of exposure. Fleiss' kappa for each hazardous agent and occupation was used to determine agreement among the 30 experts. The JEM was expressed on a heatmap and a web-based dashboard to facilitate comparison of factors affecting exposure according to each occupation and hazardous agent. Results Awkward posture, heat/cold, heavy lifting, and noise were hazardous agents regarded as exposure is probable by at least one or more experts in all occupations, while exposure to asphalt fumes was considered hazardous in the smallest number of occupations (n = 5). Based on the degree of agreement among experts, more than half of the harmful factors and most occupations showed fair to good results. The highest risk value was 16 for awkward posture for most occupations other than safety officer. Conclusions The KoConJEM provides information on the probability, intensity, and prevalence of exposure to harmful factors, including most occupations employing construction workers; therefore, it may be useful in the conduct of epidemiological studies on assessment of health risk for construction workers.

Objectives The dermal exposure route is expected to become increasingly significant relative to total worker exposure as inhalational exposure limits continue to decrease. However, standardization of occupational exposure assessment methods and scientific consensus are needed. This is the first scoping review mapping the literature across all dermal exposure assessment methods and their targeted substances/chemicals in occupational settings. Methods Eligibility criteria broadly included studies reporting any noninvasive dermal exposure assessment method in an occupational setting. The literature search (Web of Science and MEDLINE) was restricted to peer-reviewed, primary literature published in the last 20 years (2002–2022). Titles/abstracts were dual independently screened. Data charting was performed by a single reviewer using standard template. All stages were pilot tested. The JBI (formerly, the Joanna Briggs Institute) scoping review methods and PRISMA-ScR checklist (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) were used. Results In total, 493 articles were data charted and categorized by 4 study types: methods development (22%), exposure assessment (51%), health outcomes (21%), and controls assessment (6%). Fourteen types of dermal exposure assessment methods were charted with biomarkers (51%), dosimeters (21%), and qualitative assessments such as questionnaires or surveys (17%) most common. Seventeen different chemicals/substances were charted; pesticides (28%) and polycyclic aromatic hydrocarbons (PAHs) (22%) associated with crude oil products and combustion were most common. Mapping between substances and exposure assessment method categories, pesticide dosimeters (11%), and PAH biomarker studies (14%) were most reported. Literature gaps were identified for cleaning agents, hair dyes, glycol ether, N , N -dimethylformamide/ N -methyl-2-pyrrolidone, dioxins, and bisphenol A. Conclusions To foster scientific consensus, standardization across study reporting is needed for describing: (i) exposure assessment methods used, (ii) worker tasking/conditions, (iii) targeted substances and substance state, and (iv) targeted exposure routes. Overall, this review categorizes, maps, and defines the scope of literature for occupational dermal exposure assessment methods. [ABSTRACT FROM AUTHOR]

Paramedics are increasingly being subjected to violence, creating the potential for significant physical and psychological harm. Where a patient has a history of violent behavior, hazard flags—applied either to the individual, their residential address, or phone number—can alert paramedics to the possibility of violence, potentially reducing the risk of injury. Leveraging a novel violence reporting process embedded in the electronic patient care record, we reviewed violence reports filed over a thirteen-month period since its inception in February 2021 to assess the effectiveness of hazard flagging as a potential risk mitigation strategy. Upon reviewing a report, paramedic supervisors can generate a hazard flag if recurrent violent behavior from the patient is anticipated. In all, 502 violence reports were filed, for which paramedic supervisors generated hazard flags in 20% of cases (n = 99). In general, cases were not flagged either because the incident occurred at a location not amenable to flagging or because the supervisors felt that a hazard flag was not warranted based on the details in the report. Hazard flagging was associated with an increased risk of violence during subsequent paramedic attendance (Odds Ratio [OR] 6.21, p < 0.001). Nevertheless, the process appears to reliably identify persons who may be violent towards paramedics. [ABSTRACT FROM AUTHOR]

BACKGROUND: Caregivers assist patients in treatment based on their care needs and living activities. Very few studies have been conducted specifically on the occupational health and safety of hospital caregivers. OBJECTİVE: This study aimed to investigate the prevalence of excessive workload and low back pain among hospital caregivers and to identify potential associated factors. METHODS: This cross-sectional study included caregivers working at Gazi University Hospital. Socio-demographic and working-life characteristics were assessed. The Role Overload Scale was used to determine excessive workload and the Roland-Morris Disability Questionnaire was used to evaluate low back pain. RESULTS: The study included 528 participants. A total of 18.7% had work accidents in their department. 49.0% had sharp injuries. 68.9% of the participants performed tasks such as positioning, turning, lifting, or helping patients to walk. 72.2% stood for a long time during the workday. 52.8% thought that they worked under stress. 57.6% had low back pain in the last year and 38.6% in the last month, Significant differences exist in low back pain according to gender, body-mass index, standing for a long time and working under stress. Those who worked at night, had a work accident, positioned patients, stood for a long time, and worked under stress had higher mean scores on the Role Overload Scale. CONCLUSION: Tools should be used to lift and transport patients. In addition to occupational health and safety training, awareness of musculoskeletal risks should be increased. Employee well-being can be improved through exercise and stress reduction techniques. [ABSTRACT FROM AUTHOR]

Background: Nurses have faced significant personal and professional stressors during the COVID-19 pandemic that have contributed to increased rates of burnout, intention to leave, and poorer work engagement. Resilience has been identified as a critical factor influencing job outcomes; however, the dynamics of this association have not yet been investigated within the context of the Thai workforce. The study objective was to determine the associations between resilience and job outcomes, including burnout, intention to leave, and work engagement among nurses working in Thailand during the COVID-19 pandemic. Methods: This cross-sectional study gathered data from a sample of 394 registered nurses employed across 12 hospitals. The research instruments comprised the Connor–Davidson Resilience Scale (CD-RISC), the Maslach Burnout Inventory-Health Services Survey (MBI-HSS), a questionnaire assessing the intention to leave the job, and the Utrecht Work Engagement Scale (UWES). To determine the associations among the measured variables, multivariate logistic regression analyses were conducted. Results: One-third of nurses experienced emotional exhaustion and depersonalization, and about half experienced reduced personal accomplishment; one-tenth of nurses intended to leave their job. Nurses who exhibited higher levels of resilience were found to have a significantly reduced likelihood of experiencing high emotional exhaustion, depersonalization, and a diminished sense of personal accomplishment. Conversely, these nurses were more likely to report higher levels of work engagement than their less resilience. Conclusion: The COVID-19 pandemic offers important lessons learned about promoting the well-being of the nursing workforce and protecting against adverse job outcomes. While we identified resilience as a significant predictor of several nurse outcomes, other work environment factors should be considered. Government and hospital administrations should allocate resources for individual and organizational-level interventions to promote resilience among frontline nurses so that hospitals will be better prepared for the next public health emergency and patient and nurse outcomes can be optimized.

Background: Implementing appropriate shift work schedules can help mitigate the risk of sleep impairment and reduce fatigue of healthcare workers, reducing occupational health and safety risks. In Australia, the organisation has a responsibility to make sure all reasonable measures are taken to reduce fatigue of staff. Therefore, it is important to assess what the current rostering processes is for staff responsible for creating the rosters for nurses. Aim: The aims of the project were to understand (1) who creates the rosters and what the process is, (2) what training and knowledge these staff have in establishing rostering schedules that optimise the sleep and wellbeing of staff, and (3) what the benefits and limitations are of current rostering practices. Methods: Findings were generated through semi-structured interviews, using cluster coding to form categories. Twenty four nurses responsible for rostering staff were interviewed from three different sites in Victoria (one metropolitan and two regional/rural hospitals). Data was analysed using selected grounded theory methods with thematic analysis. Results: The common themes that came out of the interviews were that rostering staff were under prepared, unaware of fatigue and safety guidelines and polices from governing bodies and had not received any education or training before taking on the role. The most common rostering style was self-rostering, where staff could submit preferences. However, there were concerns about staff fatigue but were divided as to who should be responsible, with many saying it was up to staff to preference shifts that they could cope with. The final theme was cultural barriers to change. Conclusion: While self-rostering resulted in staff having more freedom and flexibility, shift preferences may be influenced more so by a need to fit with lifestyle rather than to minimise fatigue and increase safety in the workplace. Greater consideration of the impact of shift work schedules on fatigue is required to ensure that the layers of clinical governance in health care organisations minimise the risk of occupation health and safety issues for employees delivering direct patient care.
