Aunque las tasas de accidentes laborales en los inmigrantes suelen ser más altas que las de los trabajadores nativos, se ha realizado poca investigación sobre este tema desde una perspectiva cultural. El objetivo de este estudio es doble. Primero, explorar las diferencias culturales entre el país de acogida, España en este caso, y los países de origen de los inmigrantes, en cuanto al idioma y la distancia cultural, y analizar si estas diferencias están asociadas con sus tasas de accidentes laborales. En segundo lugar, esperamos probar los efectos lineales, cuadráticos y de interacción de los valores culturales, evaluados según el modelo de Hofstede (2001), sobre los accidentes laborales según el sector económico (agricultura, industria, construcción y servicios). Se analizaron las tasas de accidentes de trabajadores inmigrantes de 38 países en España. Se estimó la distancia cultural entre países (países de origen y de acogida - España) y se usó el análisis de regresión para probar asociaciones lineales, curvilíneas y de interacción. Los resultados muestran que hablar un idioma diferente y ser culturalmente diferentes no influye en los accidentes en los inmigrantes, excepto en la agricultura, donde hablar un idioma diferente se asocia con menos accidentes. Los valores culturales nacionales (individualismo, distancia de poder, evitación de la incertidumbre, masculinidad y orientación a largo plazo) están relacionados con accidentes, ya sea linealmente (como la evitación de incertidumbre en la agricultura y la orientación a largo plazo en la industria, construcción y servicios) o cuadráticamente (como la distancia de poder y la evitación de la incertidumbre, en construcción y servicios), o se modulan entre sí (la distancia de poder modula el individualismo en la industria). Los valores culturales en sí mismos, en lugar del idioma o la distancia cultural entre países, son mejores predictores de la variación de los accidentes laborales en los inmigrantes. Se analizan las similitudes y diferencias entre los sectores económicos y se hacen propuestas para mejorar los programas de intervención para prevenir accidentes

Pneumatic nail guns are hand-held tools used in industrial and construction settings. Nail guns cause the most trauma with hospitalization among construction workers. To our knowledge, we report for the first time a case of pneumomediastinum from a nail gun injury to the hand. Our patient was a 40-year-old male construction worker who shot a nail gun into his hand. He became acutely dyspneic and was found to have a pneumomediastinum due to air insufflation. He later underwent tube thoracostomy and intubation. To our knowledge, this is the first report of pneumomediastinum from a nail gun injury to the hand.

The annual increase in the number of occupational accidents and diseases in the Palestinian manufacturing industries confirms a serious problem that threatens the Occupational Safety and Health (OSH) in such industries, with negative consequences in the society and economy. As the Palestinian OSH data are insufficient, tightwad, and with discrepancies in published data by different agencies, this study aimed to investigate the OSH status in the Palestinian manufacturing industries and determine the Palestinian OSH trends rates based on international practice in the EU and USA. Also, to shed light on the OSH situation in the manufacturing sector and warrant the inspection and monitoring of industries by the respective officials. The OSH data of 175 industrial establishments and 199 industrial employees was collected by meetings, interviews, and structured questionnaires for the period 2009-2016. The US and EU OSHA (Occupational Safety and Health Administration) formulas were used to calculate the OSH rates. The analysis showed that 32.30% of the industrial employees suffered from occupational injuries. The average injury rate was 7566 per 100,000 workers, indicating a low OSH level in the Palestinian manufacturing industries. The leather industry was found as the most dangerous in terms of OSH, with an average safety performance factor (SPF) of 145.6 off days/accident. Pearson's chi-square test (χ2) revealed a correlation between occupational accidents and injuries and the employees' commitment and lost working days. An OSH framework was developed based on safety and sustainable development pillars to assure effective enforcement of the OSH law and prevent future occupational accidents and diseases.

The implementation of precursor management can improve safety performance of construction projects through effectively managing the correlations between construction accidents and their precursors. However, a system of comprehensive knowledge about what precursors mean within the context of construction safety is still lacking. This study aims to capture the nature of precursors in the construction industry and explore the process of a precursor event evolving into a construction accident to fill this gap. Based on 135 construction accident reports in China, this study adopts grounded theory to identify different types of accident precursors and explore their interactions with the development of the accident. An indicator system of precursors for construction accidents was developed, which included two major categories of precursors: behavioral factors and physical factors and five minor categories of precursors: individual behavior factors, organizational driving factors, objective physical factors, construction environmental factors, mechanical equipment factors. In addition, a precursor management strategy that includes the three stages of identification, response and effectiveness testing was established. The results of the study reveal the correlations between precursors and construction accidents, which can promote construction professionals' better understanding about precursors and improve their capabilities of managing precursors in practice.

OBJECTIVE: To estimate the incidence and time trend of typical work accidents in the textile and clothing industry in Santa Catarina from 2008 to 2017. METHODS: This was a retrospective epidemiological study based on data from the Annual Social Information Report (RAIS). The time trend was analyzed by calculating the average annual change and logistic regression. RESULTS: There was a downward trend in the incidence of occupational accidents in Santa Catarina during the period studied (8.8%). The highest incidence occurred in 2008 among men (12.6%), workers aged between 40 and 49 years (6.7%), black people (7.4%), people with less than 12 years of education (5.0%), with an average income of 3 to 7 minimum wages (7.0%), with up to 4 years of employment (6.9%), workers in the manufacture of textile products (10, 3%), medium-sized establishments (that is, between 100 and 499 workers; 7.9%) and in the regions of Greater Florianópolis (7.0%) and Vale do Itajaí (6.8%). CONCLUSIONS: The risk for typical occupational accidents dropped significantly over the period studied. However, future studies are needed to analyze new relationships that may point to other associated factors. It is hoped that this study can contribute to support measures for the prevention, promotion, protection and rehabilitation of the health of workers in this production sector.

Fatalism refers to the attitude of treating negative situations as inherent to destiny or as outcome of divine will. Considering the fatalism consequences impact in the transformative action and having elected Martin-Baró as theoretical reference, the present article reviewed the nuances of fatalism in the narratives of industrial workers, who reported on the repercussions of work accidents on their lives. From the data of a previous qualitative investigation, conducted through open and in-depth interviews, three interviews were selected whose narratives represented different facets of fatalism. The information accessed was analyzed and categorized, at which time the elements of the experiences that ensured the maintenance of fatalism and the movements of consciousness that, also from experience, challenged conformism and indicated a potential rupture with fatalism were highlighted.

O fatalismo refere-se à atitude de tratar situações negativas como inerentes ao destino ou como produtos da vontade divina. Considerando suas consequências para a ação transformadora e tendo Martin-Baró como referencial teórico, no presente artigo foram analisadas as nuances do fatalismo nas narrativas de trabalhadores industriais que relataram as repercussões em suas vidas, dos acidentes de trabalho que sofreram. Do acervo de uma pesquisa qualitativa anterior, realizada por meio de entrevistas abertas e em profundidade, foram selecionadas três entrevistas cujas narrativas representavam diferentes facetas do fatalismo. As informações acessadas foram analisadas e categorizadas, momento no qual foram destacados os elementos das vivências que garantiam a manutenção do fatalismo e os movimentos da consciência que, também a partir da experiência, desafiavam o conformismo e indicavam uma potencial ruptura com o fatalismo.

INTRODUCTION: Muscular hernias in the lower limb are a rare entity that have seldom been described in the literature, from 1929 about 200 cases of muscle hernias have been described. CASE: Here, we present a case of tibialis anterior muscle hernia and discuss the aetiology behind the same. Furthermore, we attempt to amalgamate existing knowledge to provide some guidance for investigation and management of this important diagnostic consideration. CONCLUSION: Lower limb hernias are rare but should be considered as a differential for unidentified lower limb swellings. There is no clear consensus in literature about treatment, so every case must be individualized

OBJETIVOS/INTRODUCCIÓN: Las hernias musculares son raras, donde se evidencian con más frecuencia son en las extremidades inferiores siendo el tibial anterior el músculo más afectado. En este artículo describimos un caso de hernia muscular de tibial anterior y su evolución clinica, además de revisión de la literatura actual sobre el tema.

BACKGROUND: As the pandemic process, COVID-19 has a serious occupational safety risk for healthcare professionals. Therefore, determining their health and safety perceptions and attitudes in the pandemic process is very important. This study aims to determine which is more effective in work accident prevention behavior: safety awareness and competencies of healthcare professionals or perception of fatalism. METHOD: For this purpose, a questionnaire was applied to 326 healthcare professionals. The questionnaire consists of four parts: (1) demographic information of the employees, (2) scale of preventing occupational accidents, (3) fatalism perception scale in occupational health and safety, and (4) security awareness and competency scale. Descriptive statistical methods, multiple regression and correlation analysis were used in the analysis of the data. RESULTS: It was determined that the participants' safety awareness and competencies were at the high level and their fatalism perceptions were at the low level. The average of the responses given by the participants to the scale of preventing work accidents was above the middle level. According to the study, the safety awareness and competencies of health workers were found to be about three times more effective on the behavior of preventing work accidents than the perception of fatalism. CONCLUSION: In conclusion, it is important to recommend managers to take the step to increase the safety awareness and competencies of those working in their institutions.

ABSTRACT Objective: build and validate an educational video as a strategy to encourage adherence of nursing professionals to Standard Precautions. Methods: in the first phase, a descriptive study was conducted with 197 nursing professionals from two hospitals in Cuiabá, Mato Grosso, Brazil, to identify knowledge and factors affecting adherence to Standard Precautions; data were collected using the Questionnaire for Knowledge and Compliance with Standard Precaution (Portuguese version). In the second phase, a methodological study and an educational video were developed with the results obtained in the first phase, structured according to Nola Pender's Revised Health Promotion Model. The Delphi technique was used in video validation, a process involving 13 specialists. Results: knowledge of nursing professionals about Standard Precautions ranged from 6.1% to 99%. The major deficits were related to the objectives and purposes of Standard Precautions. Adherence ranged from 36.0% to 95.4% and was low regarding the proper use of some personal protective equipment, recapping of used needles, hand washing after removing gloves, and procedures after exposure to biological materials. The script was validated in two rounds, reaching 82.3% and 92.8% of consensus, respectively, and the video was validated in the third round, with a 92.3% consensus. Conclusion: lack of knowledge about the objectives and purposes of Standard Precautions was observed among nursing professionals, and many of them do not fully adopt them. The video was considered valid by the specialists and can be used to expand knowledge and, consequently, encourage adherence of nursing professionals to Standard Precautions.

SUMMARY: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and its associated disease (COVID-19) represent a global health emergency that requires integrated and multidisciplinary intervention by international medical and scientific communities, in support of the national governments. In Italy many public health measures have been adopted to contain the transmission of the disease, which also involved occupational physicians. The regulatory path has had a rapid evolution due to the trend of infections and progressive scientific evidence: the most recent Circular from the Ministry of Labor and Social Policies and the Ministry of Health provides for the termination of the "exceptional health surveillance" activity, the management and protection of fragile individuals by activating the medical examination on request of the employee and excludes the old age, without comorbidities, as a specific condition of risk of serious complication of SARS-CoV-2 infection. For preventive and insurance purposes, COVID-19 usually represents a generic biological risk, for which the same measures must be adopted for the entire population. In the Inail Circular no. 13 of April 3, 2020, however, it is stated that professional categories that perform front office duties are considered exposed to a higher risk, as well as, health professionals, can be considered exposed to a specific risk. From January 1st to July 31st 2020, 51,363 cases of infection from SARS-CoV-2 were reported to INAIL as an accident. In the same period INAIL noticed a decrease in reports of accidents and occupational disease overall, correlated to the effects of lockdown and smart working.

Risk assessment on a construction site is based on the probability and consequences of the accident. But due to the complexity of the construction processes, this new methodology for the evaluation of occupational risks, called Level of Preventive Action, develops a new parameter for evaluating preventive action based on documentary environment that reflects the complexity of the work units, location and interdependence, construction environment referred to construction and protection systems, and social environment relative to the perception of the environment and the workers' emotional states. The evaluation criteria of the new method are established by developing the William T. Fine methodology and incorporating concepts such as risk tolerance, the importance of work and personal satisfaction, which justify the degree of correction of preventive actions. This methodology determines the amount of preventive action control that is required during the construction process. This research proposes a risk assessment protocol adapted to construction sites based on specialized technical observation with a psychosocial survey on site. Some results of the implementation of the method in real work are shown. In conclusion, the determining parameter towards optimal control of preventive action is the direct and active participation of workers in safety matters.

BACKGROUND: The construction industry is characterized by a high prevalence of accidents and injuries. Inadequate risk management measures, including failure to use or incorrect use of personal protective equipment (PPE) may significantly increase the risk of accidents. OBJECTIVES: The main objectives of the current study were to measure the prevalence of PPE use and accidents and their associated factors among construction workers. METHODS: A cross-sectional field study with an analytic component was carried out on 384 workers from different sites in Port-Said, Egypt, using an interview administered questionnaire. The questionnaire included sociodemographic and occupational data, practice of PPE use and accident analysis. RESULTS: About 60% of workers use PPE during work. Main reasons for non-use are discomfort, lack of knowledge on how to use it and poor fit. Occupational accidents in the last 12 months were reported by 64.3% of workers. The main accident types were: being hit by falling objects, falls from height, and tool related accidents. Safety training was the significant independent predictor of PPE use (AOR=2.0). However, age, marital status, smoking, safety training, and PPE use were also significant independent predictors of accidents (AOR=2.4, 3.1, 0.5, 0.5, and 0.2; respectively). DISCUSSION: Among construction workers, PPE utilization is low with significant relation to safety training while occupational accidents are common and significantly related to safety training and PPE use. Therefore, safety training should be provided, and PPE use should be enforced at construction sites.

Human factors are important causes of hazardous chemical storage accidents, and clarifying the relationship between human factors can help to identify the logical chain between unsafe behaviors and influential factors in accidents. Therefore, the human factor relationship of hazardous chemical storage accidents was studied in this paper. First, the human factors analysis and classification system (HFACS), which originated from accident analysis in the aviation field, was introduced. Since some items were designed for aviation accident analysis, such as the item "Crew Resource Management", it is not fully applicable to the analysis of hazardous chemical storage accidents. Therefore, this article introduced some modifications and changes to make the HFACS model suitable for the analysis of hazardous chemical storage accidents. Based on the improved HFACS model, 42 hazardous chemicals storage accidents were analyzed, and the causes were classified. After analysis, we found that under the HFACS framework, the most frequent cause of accidents is resource management, followed by violations and inadequate supervision, and finally the organizational process and technological environment. Finally, according to the statistical results for the various causes of accidents obtained from the improved HFACS analysis, the chi-square test and odds ratio analysis were used to further explore the relevance of human factors in hazardous chemical storage accidents. The 16 groups of significant causal relationships among the four levels of factors include resource management and inadequate supervision, planned inappropriate operations and technological environment, inadequate supervision and physical/mental limitations, and technological environment and skill-based errors, among others.

The aim of this research was to study the impact of the unitary prevention delegates (UPDs) on the Spanish working environment. To this end, a cross-sectional study was carried out using microdata from the National Survey on Health and Safety Management in Companies (ENGE-2009) with a sample of 5147 work centres. To measure the relationship between the presence of UPD in workplaces with preventive management indicators and damage to health, individual and multiple logistic regression models were carried out, calculating the crude (cOR) and adjusted (aOR) odds ratios by sociodemographic covariates, with their corresponding 95% confidence intervals (95% CI). Ambivalent results were obtained. On the one hand, a positive impact of the UPDs was found, in the management of prevention showing a higher probability of prevention plans being carried out (aOR = 3.97; 95% CI: 3.26-4.83), risk assessments (aOR = 5.96; 95% CI: 4.44-8.01) and preventive actions were planned (aOR = 3.01; 95% CI: 2.55-3.56), as well as 1.56 times less likely to register minor occupational accidents (aOR = 0.64; 95% CI: 0.53-0.76). On the other hand, the presence of the UPDs did not promote the activation of a participatory culture and did not reduce the probability of suffering serious and fatal accidents at work. In conclusion, UPDs need to activate workers' participation to improve results.

The ability to identify factors that influence serious injuries and fatalities would help construction firms triage hazardous situations and direct their resources towards more effective interventions. Therefore, this study used odds ratio analysis and logistic regression modeling on historical accident data to investigate the contributing factors impacting occupational accidents among small electrical contracting enterprises. After conducting a thorough content analysis to ensure the reliability of reports, the authors adopted a purposeful variable selection approach to determine the most significant factors that can explain the fatality rates in different scenarios. Thereafter, this study performed an odds ratio analysis among significant factors to determine which factors increase the likelihood of fatality. For example, it was found that having a fatal accident is 4.4 times more likely when the source is a "vehicle" than when it is a "tool, instrument, or equipment". After validating the consistency of the model, 105 accident scenarios were developed and assessed using the model. The findings revealed which severe accident scenarios happen commonly to people in this trade, with nine scenarios having fatality rates of 50% or more. The highest fatality rates occurred in "fencing, installing lights, signs, etc." tasks in "alteration and rehabilitation" projects where the source of injury was "parts and materials". The proposed analysis/modeling approach can be applied among all specialty contracting companies to identify and prioritize more hazardous situations within specific trades. The proposed model-development process also contributes to the body of knowledge around accident analysis by providing a framework for analyzing accident reports through a multivariate logistic regression model.

The chemical industry has made great contributions to the national economy, but frequent chemical plant explosion accidents (CPEAs) have also caused heavy property losses and casualties, as the CPEA is the result of interaction of many related risk factors, leading to uncertainty in the evolution of the accident. To systematically excavate and analyze the underlying causes of accidents, this paper first integrates emergency elements in the frame of orbit intersection theory and proposes 14 nodes to represent the evolution path of the accident. Then, combined with historical data and expert experience, a Bayesian network (BN) model of CPEAs was established. Through scenario analysis and sensitivity analysis, the interaction between factors and the impact of the factors on accident consequences was evaluated. It is found that the direct factors have the most obvious influence on the accident consequences, and the unsafe conditions contribute more than the unsafe behaviors. Furthermore, considering the factor chain, the management factors, especially safety education and training, are the key link of the accident that affects unsafe behaviors and unsafe conditions. Moreover, effective government emergency response has played a more prominent role in controlling environmental pollution. In addition, the complex network relationship between elements is presented in a sensitivity index matrix, and we extracted three important risk transmission paths from it. The research provides support for enterprises to formulate comprehensive safety production management strategies and control key factors in the risk transmission path to reduce CPEA risks.
