Chapitre 4. L'accident du travail chez soi.

The widespread use of teleworking during the health crisis reduced the flow of occupational accident claims by 20%. This applies to commuting accidents, as well as claims related to « immediate » or “deferred” risks (Rapp. annuel 2020 de l’Assurance maladie - Risques professionnels : Eléments statistiques et financiers, déc. 2021, p. 2 and 113). On the basis of these figures, working at home could be analyzed as a means of preventing occupational risks and improving workers’ health. In reality, however, these figures should not obscure the fact that telecommuting is a major occupational hazard. This is all the more the case given that, while telecommuting was not very widespread before the pandemic, it is now popular with employees and is being developed by many companies as a source of productivity (Rapp. CNP, May 16 2022). We therefore need to keep a close eye on the development of workplace accident legislation in this area, its adaptability to the specific claims experience of teleworkers and its perfectibility, not forgetting the thorny question of the possible recognition of the employer’s inexcusable fault in the event of the accident being covered by professional legislation.

Research on the evolutionary control of unsafe behavior of construction personnel based on multi-field coupled-homogeneous analysis model.

Unsafe behavior among construction personnel poses significant risks in petroleum engineering construction projects. This study addresses this issue through the application of a multi-field coupled homogeneous analysis model. By conducting case analyses of petroleum engineering construction accidents and utilizing the WSR methodology, the influencing factors of unsafe behaviors among construction personnel are systematically categorized into organizational system factors, equipment management factors, and construction personnel factors. Subsequently, employing Risk coupling theory, the study delves into the analysis of these influencing factors, discussing their coupling mechanisms and classifications, and utilizing the N-K model to elucidate the coupling effect among them. Furthermore, a novel approach integrating coupling analysis and multi-agent modeling is employed to establish an evolutionary model of construction personnel's unsafe behavior. The findings reveal that a two-factor control method, concurrently reinforcing equipment and construction personnel management, significantly mitigates unsafe behavior. This study provides valuable insights into the evolution of unsafe behavior among construction personnel and offers a robust theoretical framework for targeted interventions. Significantly, it bears practical implications for guiding safety management practices within petroleum engineering construction enterprises. By effectively controlling unsafe behaviors and implementing targeted safety interventions, it contributes to fostering sustainable development within the petroleum engineering construction industry.

Developing a risk framework for assembly construction based on stakeholder theory and structural equation modelling.

Occupational injuries in the construction industry have plagued many countries, and many cases have shown that accidents often occur because of a combination of project participants. Assembled construction (AC) projects have received extensive attention from Chinese scholars as a future trend, but few studies have explored the interrelationships and potential risks of various stakeholders in depth. This study fills this research gap by proposing a multi-stakeholder AC risk framework. The study surveyed 396 stakeholders, then analyzed the collected data and created a risk framework based on Structural Equation Modelling (SEM) and the CRITIC weighting method. The results revealed that factors like "regular supervision is a formality," "blindly approving the wrong safety measures," and "failure to organize effective safety education and training." are vital risks in AC of China. Finally, the study validates the risk factors and the framework with 180 real-life cases, which shows that the proposed framework is theoretically grounded and realistic. The study also suggests multi-level strategies such as introducing AI-based automated risk monitoring, improving the adaptability of normative provisions to technological advances, and advancing the culture of project communities of interest to ensure AC's safe practices.

Establishment-level safety analytics: a scoping review.

The use of data analytics has seen widespread application in fields such as medicine and supply chain management, but their application in occupational safety has only recently become more common. The purpose of this scoping review was to summarize studies that employed analytics within establishments to reveal insights about work-related injuries or fatalities. Over 300 articles were reviewed to survey the objectives, scope and methods used in this emerging field. We conclude that the promise of analytics for providing actionable insights to address occupational safety concerns is still in its infancy. Our review shows that most articles were focused on method development and validation, including studies that tested novel methods or compared the utility of multiple methods. Many of the studies cited various challenges in overcoming barriers caused by inadequate or inefficient technical infrastructures and unsupportive data cultures that threaten the accuracy and quality of insights revealed by the analytics.

Safety: A collective and embedded competency. An ethnographic study of safety practices at an industrial workplace in the Netherlands.

INTRODUCTION: Organizations place strong emphasis on the standardized occupational health and safety procedures to reduce work-related illnesses and workplace accidents. However, standardized procedures are not always followed up in daily work practices. Organizations must cope with the differences between standardized procedures and local adaptation by employees. METHODS: This ethnographic field study at an industrial workplace in the Netherlands provides insights into employees' everyday work practices, how these work practices are shaped, and how they relate to local occupational health and safety procedures. Acknowledging safety as a competency embedded in work practices, as introduced by Gherardi and Nicolini (2002), offers a theoretical point of view for looking beyond the dichotomy of standardization and local adaptations. RESULTS: The results show that a standardized and noncontextualized occupational health and safety management system that focuses on accident-free days and compliance actually leads to ignorance of practical and tacit competences of workers and no learning and improvement of safety procedures can take place. However, our findings also illustrate how employees in their informal everyday work practices reduce the risks produced by the safety system itself. CONCLUSION: Overall, the results indicate that social interactions among employees, leaders, and management within the organization play an important role in workplace safety. The analysis highlights the value of vulnerability and trust in relationships at work to be able to learn and develop safety procedures that align with local demands. PRACTICAL APPLICATIONS: This study emphasizes the need for participatory approaches in creating safer and healthier workplaces. The cocreation of occupational health and safety (OHS) rules and procedures, however, can only function if they are combined with a responsive leadership style.

Risk self-perception and occupational accidents.

INTRODUCTION: This study analyzes the relationship between measures of occupational accidents and workers' perception of risk in the workplace using nationally representative data on workers' characteristics and a complete record of occupational accidents. METHODS: Regression analyzes addressing both the ordinal nature of the dependent variable and causality were conducted to control for different sociodemographic factors influencing workers' perceptions of occupational risks. Special attention was paid to the risk level of the worker's workgroup, existence of family responsibilities, organizational safety culture, and measures of accident rates. RESULTS: Individuals showed different perceptions of risk based on their personal and work characteristics. Significant associations were observed between each variable of interest and risk perception. Overall, the results remain robust across specifications addressing both simultaneity and ordinality. CONCLUSIONS: Employees' "reading" of hazards was not fully aligned with objective information on occupational accidents but depended on individual characteristics. Having family responsibilities or being unionized increased workers' risk perception, whereas belonging to a workgroup with higher accident rates reduced it. PRACTICAL APPLICATIONS: Knowing how workers perceive risk and how this perception deviates from statistical information on accidents are essential for management to accurately design safety measures. In this regard, specific characteristics such as age, having dependents in the family, or the typology of the workers' workgroup should be taken into account. Greater knowledge of preventive measures will improve the way workers perceive risk, and ultimately contribute to reducing the likelihood of occupational accidents.

24Model-based comparative analysis of two catastrophic hazardous chemical pipeline accidents.

Objectives. This study conducted a comparative analysis of two catastrophic pipeline accidents in China in order to identify some common mistakes and lessons learned to prevent similar accidents. Methods. The 24Model was used in this study, which provides a universal pathway for accident analysis from the individual level to the organizational level. Results. There were similarities between the two cases in the aspects of the occurrence, development, emergency and causation at different levels: both were caused by leaks of pipelines and evolved into multiple explosions during emergency response; both leaks were caused by the corrosion of pipelines in the confined space of a damp or salt-spray environment; both were classified as 'responsibility accidents', and unsafe acts, such as the failure to identify hidden hazards of pipelines that were the direct cause of accidents, reflected the shortcomings of individual safety habitual behaviour in terms of knowledge, awareness, habits and psychology; weaknesses in the organizational management mainly concerned hazard identification, pipeline maintenance, emergency disposal, etc.; and there is not a good safety climate within the organization. Conclusions. Organizations should develop a closed-loop management system and strengthen the construction of safety culture, and the government should supervise the implementation of procedures.

Correlational analysis of occupational accidents and the safety policies in the Chinese coal mining industry from 2008 to 2021.

This study investigates the correlation between previous coal mine safety policies and accidents in China. Data on coal mine accidents and government regulatory information from 2008 to 2021 are collected. The characteristics of coal mine accidents are analyzed, and safety policy indexes are identified. An ordinary least squares (OLS) regression model is established to quantitatively analyze the correlation between accidents and safety policy. The study finds that safety policies have some impact on accident occurrence in coal mines. Although there has been a decrease in accidents and deaths over time, higher mortality rates are observed during periods of increased production intensity and on weekends. Gas accidents are the most common, followed by roof and flood accidents. The study concludes that national safety policies with wider coverage and a stronger system are effective in preventing accidents, but caution should be exercised to avoid reduced vigilance with decreasing death rates.

Descriptive summary of fatal work-related injuries, Western States, 2011-2017.

Work-related deaths are a persistent occupational health issue that can be prevented. However, prevention opportunities can be hampered by a lack of adequate public health resources. The Western States Occupational Network (WestON) is a network of federal, state, and local occupational health professionals that includes a 19-state region of the United States. To encourage public health collaboration, WestON partners examined work-related fatalities within the region. Fatality counts (numerators) were obtained from the U.S. Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries restricted-access research files for all workers ages ≥15 years and fatally injured in WestON states from 2011 through 2017. Estimates of full-time equivalent hours worked (FTE) (denominators) were retrieved from the BLS Current Population Survey. Annual average fatality rates were calculated as number of fatalities per 100,000 FTE over the study period. Rates were stratified by state, select demographics, industry sector, and event/exposure types. Pearson chi-squared tests and rate ratios with 95% confidence probability limits were used to assess rate differences. All analyses were conducted using SAS v.9.4. From 2011 through 2017, the annual average overall occupational fatality rate for the WestON region was 3.5 fatalities per 100,000 FTE, comparable to the overall U.S. fatality rate. Male workers had a fatality rate almost 10 times higher than female workers in the region. Fatality rates increased with successive age groups. Alaska and New Mexico had significantly higher fatality rates for all racial/ethnic groups compared to respective regional rates. Wyoming, North Dakota, and Montana had the three highest occupational fatality rates among foreign-born workers. Agriculture/forestry/fishing, mining/oil/gas extraction, and transportation/warehousing/utilities were industry sector groups with the three highest fatality rates regionally. Transportation-related incidents were the most frequent event type associated with occupational fatalities for all 19 states. Work-related fatalities are a crosscutting occupational public health priority. This analysis can be an impetus for collaborative multistate initiatives among a dynamic and varied occupational public health network to better meet the needs of a rapidly changing workforce.

Research on the decision-making of work safety investment in industrial park enterprises: evidence from behavioral experiments.

Due to the clustering of risk factors, industrial park safety accidents can easily trigger a domino effect. Work safety investment is the foundation of enterprise work safety in industrial parks. Therefore, increasing the work safety investment of enterprises in industrial parks is the key condition to prevent accidents. However, due to the typical negative externalities of industrial park work safety accidents, the decision-making process of work safety in park enterprises is influenced by other enterprises within the park, including imitation behaviors. This makes the decision-making of work safety in park enterprises very specific. In order to clarify the influencing factors and effects of work safety investment in industrial park enterprises, this study uses a behavioral experiment method and conducts decision-making experiments using the experimental platform O-Tree. The study recruits 76 participants who play the role of decision-makers in park enterprises. This study uses a lottery price experiment and a dictator experiment to measure the risk preference and altruism preference of the participants, respectively. The study introduces the real background of work safety investment in industrial park enterprises and collects data on work safety investment by the participants in different experimental scenarios. The research results show that the safety attitudes of decision-makers, altruism preference, accident experience, government work safety supervision, park management measures, and safety benefits positively influence work safety investment in park enterprises. The risk preference of decision-makers and the resource capability of work safety negatively influence work safety investment in park enterprises. Work safety investment in park enterprises is influenced by the work safety investment of other enterprises within the park.

Tractors, Trees, and Rollover Protective Structures: A Cause for Concern.

Injury and fatality events that are caused by tree work and tractor-related activities contribute to the already elevated rates of work-related injuries in the agriculture and logging sectors. This brief report highlights the circumstances surrounding these events, as well as a number of surveillance sources that identify the extent to which they contribute to the injury burden in these hazardous industries. These data sources include fatality investigations, agricultural injury news reports, consumer product injury data captured from emergency rooms and near-miss reporting data captured from individuals participating in the National Rollover Protective Structure Rebate Program (NRRP). Several recommendations for further research and interventional efforts are outlined, with particular consideration of the manner in which rollbars have been involved in falling object incidents.

Identifying key accident causation factors in the Malaysian construction industry.

Objectives. Notwithstanding its economic importance, the construction industry is still facing challenges due to its high accident record. As a result, the goal of this study is to identify the key underlying causes of accidents in the Malaysian construction industry that construction stakeholders can focus on to reduce the menace of accidents in the industry. Methods. To achieve this goal, relevant literature was reviewed in order to identify the causes of accidents. The identified factors were used to develop the survey questionnaire for collecting primary data, and the collected data were analysed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Results. The results of the EFA and CFA establish and confirm 11 clusters for the causes of accidents on construction sites: management problems; inadequate training; inadequate supervision; mental health problems; bad attitudes; inadequate funding; inadequate experience; material and equipment handling; poor safety practices; inadequate orientation; and work environment. Conclusion. The study concludes that addressing all 11 factors will drastically reduce the incessant accident occurrences in the construction industry. The result of this study will help construction stakeholders know where to direct their energy in an effort to reduce construction accidents.

Investigation of non-fatal occupational accidents and their causes in Turkish shipyards.

This study reports new data for 1028 non-fatal occupational accidents dated between January 2010 and April 2015 by applying the analytical hierarchy process (AHP) technique. A comprehensive survey was conducted at four shipyards in Tuzla, Istanbul and Yalova regions in Turkey and a workplace questionnaire appropriate for the AHP technique was carried out. The obtained results indicated that inadequate safety equipment and protective clothing, unsuitable usage of machines and tools, and disobeying occupational health and safety (OHS) procedures were the most common risk factors for the accidents. Hence the preventive measures could be identified by analyzing non-fatal accident data. After the identification of the descriptive measures, the priority order of these measures was asked of the occupational safety professionals in the shipbuilding industry, and we used the AHP method to evaluate the results.

Analysis of characteristics and causes of gas explosion accidents: a historical review of coal mine accidents in China.

Objectives This study aimed to provide greater insight into the characteristics of severe and extraordinarily severe gas explosion accidents (SESGEAs). Methods. The study analyzed the accident characteristics and causes of SESGEAs. As an example, we conducted a specialized case analysis using the 24Model (fourth edition) on the recent Baoma coal mine gas explosion. Results. SESGEA data are characterized by greater volatility, with significant differences in the geographical distribution, temporal distribution and attributed characteristics of the accidents. From the accident analysis: chaotic ventilation management was the most serious accident cause of SESGEAs; unsafe acts related to ventilation operations accounted for 18.51% of all unsafe acts; coal miners lack professional safety knowledge and have a serious fluke mentality in mining work; enterprises have insufficient enforcement of safety procedure documents, and lack of attention to the allocation of underground human resources and safety training systems; and the importance of safety, the role of the safety department and satisfaction with safety facilities have become the most serious missing items of safety culture. Conclusion. This study can provide important data support and management basis to assist mine operators in developing more targeted accident prevention strategies.

Farm operations and slips, trips, and falls among corn farm workers in Thailand.

Slips, trips, and falls (STFs) represent a main source of injury among farm workers. The purpose of this study was to evaluate the association between farm operations and STFs among corn farm workers. We conducted a cross-sectional study using a self-administered questionnaire among corn farm workers in Nan and Saraburi provinces, Thailand from July 5 to 23, 2022. Poisson regression analysis was used. Among 338 participants, 122 (36.1%) had experienced an STF in the previous 6 months. Conducting very frequent, frequent, or occasional pest management was associated with a higher incidence rate ratio (IRR) of STFs than never or rarely pest management (adjusted IRR 1.93, 95% confidence interval [CI]=1.23 to 3.04, p=0.004). People with marginal or unsatisfactory work break lengths had a higher incidence rate of STFs than those with satisfactory work breaks (adjusted IRR 1.40, 95% CI=1.03 to 1.89, p=0.030). We found that corn farm workers in our study often experienced STFs, which was associated with a high frequency of pest management practices and inadequate work breaks. Reducing the physical burden of pest management may be effective as an STF prevention strategy.

Knowledge Shared by Alaska Native Commercial Salmon Set Gillnetters in Norton Sound to Reduce Marine Fatalities.

OBJECTIVES: The goal of this exploratory pilot study was to reduce marine fatalities in Norton Sound using knowledge shared from Alaska Native salmon set gillnetters in Unalakleet, AK. The following objectives to address this goal were: 1) identify factors that influence safety for Alaska Native commercial set gillnetters in Norton Sound; 2) use findings from objective 1 to improve commercial fishing training, education, and resources; and 3) disseminate and communicate results from objective 1 to commercial fishers in the Norton Sound fleet, commercial fishing safety partners, and the Alaska Native injury prevention community. METHODS: Ten semi-structured interviews were conducted with Alaska Native commercial set gillnetters in Unalakleet, AK. We utilized knowledge shared to identify factors that influence safety for their fleet. Using an Interpretative Phenomenological Analysis Methodology, 10 interviews were recommended for a homogenous sample. RESULTS: Most participants learned to fish at a young age from the family, with safety lessons passed on by family members. Fishing is a lifestyle and interconnected with harvesting and a way of living. Set gillnetters in Norton Sound use open skiffs and have limited access to workable Personal Flotation Devices (PFDs) and safety training. Participants reported health benefits but also negative long term physical effects, financial stress, and difficulty fishing with age. Respect and awareness of the ocean was reported as the most important strategy to reduce risk. Stories were shared of falls overboard, capsizing, and local fatalities and hazards, such as being overloaded with fish, entanglement, and maneuvering a small boat in large waves. Stronger winds and shifting weather patterns were experienced from climate change. CONCLUSION: This exploratory pilot study identified factors that influence safety for Alaska Native commercial set gillnetters. Findings should be used to 1) determine best methods to influence behaviors to reduce risks in this hazardous fishery; 2) increase awareness and promote expanded application of best practices, equipment, and resources; 3) encourage and promote outreach initiatives targeted for this unique population; and 4) develop tailored training programs for commercial fishing in an open skiff. Research with Alaska Native fishing communities will require value and respect of indigenous knowledge, collaboration with local people, and follow-up to bring findings back to the community.

[Causes of Countermeasures Against Serious Accidents Caused by Health Hazards of Chemical Substances, Based on Cases of Occupational Accidents in Japan].

The purpose of this study was to summarize the typical and specific causes and risk reduction measures of serious accidents in Japan caused by chemical substances in terms of the 10 types of human health hazards in the UN GHS (Globally Harmonized System of Classification and Labelling of Chemicals) classification. The list of "Cases of Major Accidents Caused by Chemical Substances" published on the "Safety in the Workplace Website" of the Ministry of Health, Labor and Welfare (MHLW) was linked to the "Results of GHS Classification by the Government" of the National Institute of Technology and Evaluation (NITE). Analysis was conducted by health hazards in order to obtain reference examples of measures taken against health hazards in response to the revision of the law on autonomous chemical substance management in 2022. Using the text mining tool KH Coder ver. Three using cluster analysis, we grouped causes and measures among serious disasters by health hazard, illustrated co-occurrence networks, and extracted typical examples of each in a co-occurrence network. Representative causes of and measures against occupational accidents caused by health hazardous properties were summarized from the extracted typical cases. Although few occupational accidents were caused by the health hazards of chemicals, when all health hazards were classified into acute toxicity, acute health hazard, and chronic health hazard, contact was a clear cause for many of the acute toxicity and acute health hazards, such as corrosiveness and sensitization. However, many occupational accidents were caused by the physical hazardous aspects of the chemical substances or by the safety aspects of the workplace. Causes of occupational accidents due to health hazards included unsafe behavior and unsafe conditions, or lack of understanding of the physicochemical properties of a substance and specific reactions such as mixing or hydrolysis of the substance. Typical risk reduction measures for health hazards included equipment to prevent human contact with health hazardous substances, systems to control unsafe behavior, promoting understanding of chemical reactions, and providing information about chemicals to all persons involved in testing, research, and subcontract work. The data of occupational accident cases of "death or more than 4 days lost from work" were used. Most of the cases were related to acute health hazards, but relatively few to chronic health hazards, and few occupational accidents were caused by health hazards. Most of the occupational accidents were caused by health hazards due to the physical hazards of chemical substances and inadequate workplace safety. In light of the above, it is necessary in autonomous chemical substance management to first take risk reduction measures for workplace safety and chemical physical hazards, then to prevent contact with acute toxicity and acute health hazards such as corrosiveness and sensitization, and, lastly, to take risk reduction measures for chronic health hazards, using allowable concentrations and controlled concentrations as indices.

Real-time monitoring unsafe behaviors of portable multi-position ladder worker using deep learning based on vision data.

INTRODUCTION: Fatal fall from height accidents, especially on construction sites, persist, underscoring the importance of monitoring and managing worker behaviors to enhance safety. Deep learning showed the possibility of substituting the manual work of safety managers. However, applying detection results to determine compliance with safety regulations has limitations. METHOD: This study estimated the actual working height depending on the height of the object detection bounding box by specifying the consistent hinge part as a target marker based on ladder manufacturing regulations. Furthermore, an attempt was made to improve the separation between workers, coworkers, and persons unconnected to ladder activities by applying an optimized loss function alongside an attention mechanism. RESULTS: The experimental results showed that an average precision increased from 87.60% to 90.44%. The performance of the monitoring unsafe behavior of ladder worker following the Korea Occupational Safety and Health Agency (KOSHA) guide was evaluated by 91.40 F1-Score, which accumulated sorted according to the working height. CONCLUSIONS: Experimental results show the feasibility of the real-time automate safety monitoring in ladder work. PRACTICAL APPLICATIONS: By linking the estimated working height and deep learning multi-detection results to established safety regulations, the proposed method shows the potential to automatically monitoring unsafe behaviors in construction site.

Emotional intelligence as a conduit for improved occupational health safety environment in the oil and gas sector.

To address the issue of promoting occupational health and safety at the workplace, this study aimed to evaluate the mediating effect of four different dimensional constructs of Emotional Intelligence (EI) on the influence Occupational Health and Safety Management Practices (OHSMP) hold on safety performance and workplace accidents among oil and gas workers. The study is explanatory research that adopted a cross-sectional survey design. Convenience and stratified sampling techniques were used to select 699 respondents from the three major government-owned oil and gas organizations. The multiple standard regression and bootstrapping mediation methods were used for data analysis after subjecting the data to exploratory and confirmatory factor assessments. Results indicated that OHSMP significantly predicts EI, safety performance, and workplace accidents. Again, EI was found to predict safety performance and workplace accidents significantly. Results also indicated that all the construct dimensions for measuring EI significantly explain the relationship between OHSMP and safety performance, as well as the influence of OHSMP on workplace accidents. The theoretical basis for these findings is that workers with high-level EI are likely to cope with occupational health and safety lapses or safety-related challenges at the workplace by participating and complying with the organization's safety management practices or procedures. Such employees are likely to exhibit safe working behaviors and contribute to improving safety performance in the organization.

Deaths due to hydrogen sulphide on a jack up rig at Bombay High: an avoidable accident.

An enclosed space is an area with poor or no natural ventilation which is not designed for continuous occupancy, where access is limited and which may contain a dangerous atmosphere. Enclosed space atmospheres can be hazardous due to one or a combination of the conditions which includes oxygen deficiency; presence of toxic and/or flammable gases. When it is intended that personnel should enter or work in an enclosed space, care should be taken to create and maintain safe working conditions. The case report describes an incident on board an oil rig where the rig workers were exposed to noxious gases resulting in multiple fatalities. Work involved gas sampling/monitoring at various locations inside the "spud tanks" of the rig and certifying it free of noxious gases for marine surveyor's inspection. Contributory factors that have been frequently identified following enclosed space accident investigations are non-compliance with procedures, inappropriate equipment, poor supervision, complacency and over familiarity leading to short cuts being taken, detection and monitoring equipment not used or not working properly and improper action in an emergency. Preventive measures to avoid such accidents and create a safe working area are discussed.
