Background: Workforce health is one of the primary and most challenging issues, particularly in industrialized countries. This article aims at modeling the major factors affecting accidents in the workplace, including general health, work-family conflict, effort-reward imbalance, and internal and external locus of control. Methods: A cross-sectional study was conducted in Esfahan Steel Company in Iran. A total of 450 participants were divided into two groups-control and case-and the questionnaires were distributed among them. Data were collected through a 7-part questionnaire. Finally, the results were analyzed using SPSS 22.0 and Amos software. Results: All the studied variables had a significant relationship with the accident proneness. In the case group, general health with a coefficient of -0.37, worke-family conflict with 0.10, effort-reward imbalance with 0.10, internal locus of control with -0.07, and external locus of control with 0.40 had a direct effect on occupational stress. Occupational stress also had a positive direct effect on accident proneness with a coefficient of 0.47. In addition, fitness indices of control group showed general health (-0.35), worke-family conflict (0.36), effort-reward imbalance (0.13), internal locus of control (-0.15), and external locus of control (0.12) have a direct effect on occupational stress. Besides, occupational stress with a coefficient of 0.09 had a direct effect on accident proneness. Conclusion: It can be concluded that although previous studies and the present study showed the effect of stress on accident and accident proneness, some hidden and external factors such as work-family conflict, effort-reward imbalance, and external locus of control that affect stress should also be considered. It helps industries face less occupational stress and, consequently, less occurrence rates of accidents.

Background: The series of serious industrial accidents in recent years at contractors to large companies has highlighted risk outsourcing as a real and urgent problem. This study aims to review the difference in the degree of risk exposure and the occurrence of industrial accidents depending on the type of company relations. Among in-house contractors, the focus will be on those handling hazardous chemicals that include companies for which outsourcing requires approval. Methods: This study uses the 9th wave of the Industrial Safety and Health Survey (2018). For determining the degree of risk exposure, the occurrence of industrial accidents, and industrial accident rate, multivariate, logistic, and fractional logit, regression analyses were used, respectively. Results: First, In-house contractors' degree of risk exposure is higher than that of the client companies. In particular, this gap is even greater for companies dealing with chemicals. Second, among only those that handle hazardous chemicals, in-house contractors do show a significantly higher rate of industrial accident occurrence. Third, In-house contractors have a significantly higher rate of industrial accidents from diseases than client companies. Conclusion: The analysis supports the intent of the legal amendment that strengthens the protection of in-house contracted workers who handle hazardous chemicals. Second, the results of this study suggest that safety and health management must go beyond legal compliance and ensure that it has substance and effectiveness. Last, there should be policy consideration is necessary to reduce attempts to hide industrial accidents.

Recently, the number of accidents reported involving foreign laborers has risen, and the need to prevent accidents at construction sites has become more urgent. It has been found that 90 percent of construction accidents are caused by unsafe work practices, and various studies have been conducted on these practices with the aim of preventing accidents at construction sites. However, the tendency with previous studies was to average the results of survey responses, and as a result it is impossible to consider the potential risk of how many foreign laborers feel unsafe in relation with the unsafe practices. Therefore, in this study, importance-performance analysis (IPA) was improved in order to assess the potential risk of the unsafe practices of foreign laborers at construction sites in Korea. To verify the applicability of the improved IPA, a survey was carried out, and then the results were compared with those of the IPA. Through the use of the improved IPA, unsafe practices that were not found in the previous IPA but have potential risk were identified. The method proposed in this study is expected to contribute to the prevention of construction accidents of foreign workers by enabling a more efficient management.

Recently, the criteria for assessing industrial accidents have been replaced by the mortality rate. It was found that the number of deaths from excavation work was the highest among construction machinery. The risk assessment is being conducted, however the industrial accident mortality rate has not decreased. Accordingly, this study aims to provide the basic for the create of a risk assessment model specialized in construction work at excavator. It provides absolute value from the risk model which is capable of delivery the probability of a disaster. In addition, we provide a relative risk model that compares the risk through scores between detailed works. The relative risk model is combined by likelihood and severity; the likelihood indicates the frequency of accidents and the severity indicates seriousness of fatal accidents. A variable that reflects the conditions of the construction site was added to the risk assessment model based on past disaster cases. And using the concepts of probability and average, the risk assessment process was quantified and used as an objective indicator. Therefore, the model is expected to reduce disasters by raising the awareness of disasters.

With the average life expectancy increasing thanks to better standards of living and medical technology, the number of elderly construction workers in construction sites rises every year to surpass the 450 thousand people in the construction industry (24.7% of all employees in the construction industry). Similarly, the percentage of fatal accidents involving elderly workers has stood at 41~46 percent for the past five years; note that this is significantly higher than the other age groups, making safety measures for dealing with this issue a matter of urgency. This study sought to propose appropriate safety guidelines for elderly construction workers aged 50 years and over by examining the changes in their physical and psychological functions and through the subsequent analysis of the current status and causes of fatal accidents involving them. The guidelines targeted ferroconcrete construction where accidents occur quite often; construction was classified into mold construction, reinforcing rod construction, and concrete construction. Mold construction was further classified into preparation, carry-in, processing, assembly, and disassembly, and reinforcing rod construction, into preparation/transport and processing/assembly. Safety guidelines for each process were presented by dividing them into three aspects considering the changes in the physical and psychological functions according to their ages and type of accident causes: work environment improvement, machinery and equipment improvement, and work method improvement.

In addition to being used for ascending and descending to work locations, portable ladders are widely used as a substitute for work platforms when working at heights in homes and industrial sites. However, accidents continue to occur in industrial sites owing to structural instabilities of ladders and the negligence of safety measures by users. To prevent accidents involving workers using portable ladders, it is important to encourage workers to use them correctly through laws and regulations; however, establishing effective preventive measures that go beyond regulations can increase acceptance in industrial sites and maximize the effect of reducing industrial accidents. Therefore, this study conducts a fact-finding survey and portable safety ladder product analysis and collects stakeholder opinions to develop a Korean-style safety ladder that can replace step ladders with a high risk of accidents.
