•Poor Safety remains a global challenge for construction.•AI emerges as an effective approach for enhancing safety.•Study reviews and categorizes AI applications in construction safety.•The key insights, opportunities, and challenges for AI integration are identified.
•A quantitative cross-risk assessment method was developed.•The crossover includes the crossover of risk factors and the crossover between jobs.•We explore the degree of crossover between the ...jobs.•The risk level of crossed risk is divided.
The adverse consequences of crossed risk on project construction are far greater than independent risks. Crossed risk includes not only the cross impact of risk factors, but also the mutual influence of crossover job. In the current field of construction safety management and control, there is no relevant research on quantitative methods and grading standards of crossed risk. The purpose of this paper is to develop an assessment method based on the combination of Bayesian network (BN) and the degree of crossover (DoC), which is used to analyze the interrelationship and risk ranking of the crossed risk. According to the sensitivity analysis of the BN model, it is concluded that the most prone to accidents during the construction process are the “three-violation personnel (violating command, illegal operation, and illegal labor discipline)”. DoC as a new conceptual weight is proposed that expresses the overlapped degree of crossover job. According to the developed calculation method, the crossed risk value of the construction project can be obtained. The applicability of the method is demonstrated by a case of a fire and fall accident from a chimney anti-corrosion construction project. This evaluation method can support the quantitative analysis of crossed risk in construction safety, and put forward the strategy of hierarchical control according to the results.
PurposeThe aim of this study is to reveal the effects of “safety climate” on “productive organizational energy”, based on the idea that higher energy and productivity will be seen in employees with ...the improved safety climate in the working environment.Design/methodology/approachIn this study, data were collected using an online questionnaire from 426 employees of small and medium-sized textile enterprises in the Organized Industrial Zone in the Turkish province of Gaziantep. The “easy sampling” method was applied, one of the sampling techniques not based on probability. Multiple linear regression analysis was used to examine the effects of the “Management's perspectives and rules” and “Colleagues and safety trainings” sub-dimensions of the safety climate on the “emotional”, “cognitive” and “behavioral” components of productive energy.FindingsThe findings showed that the safety climate in the workplace positively and significantly affects the productive organizational energy of employees. In addition, it was observed that the management's perspective and rules had a higher impact on productive organizational energy in attitudes towards the safety climate and productive energies of these employees compared to safety pieces of training.Practical implicationsFirst of all, the result of this study and the positive results that the safety climate in organizations might cause have been noted. It has been demonstrated that the productive energies of the employees will increase if the necessary safety climate is established in the enterprises. In addition, despite the importance attached to the safety training of the employees, as a result of the analysis, it has been determined that the management's perspective and rules (ß = 0.61; p < 0.01) have a higher positive effect on the productive energy of the employees. If these situations are considered by the managers, it is expected that the occupational health and safety management strategies created for the employees will contribute to the formation of positive behaviors in the employees.Originality/valueThe driving force of the present study is that, to our knowledge, there has been no research on this issue related to employees who are mentioned as a critical force in solving productivity and whose number is about 26 million in Turkey's population.
Due to the type of activities and the long-term exposure to chemicals, hospital cleaning workers require the necessary knowledge about the chemicals used and proper safety culture. This study aimed ...to evaluate the safety culture and perception of hospital cleaning workers' warning signs of chemical hazards.
This cross-sectional study was conducted in 2022 with the participation of 68 cleaning workers with the mean age ± (SD) and work experience ± (SD) of 36.19 ± (7.619) and 9.21 ± (5.462), respectively, in four selected Tehran hospitals in Iran. After ensuring the confidentiality of the received information and completing the demographic information checklist, each participant completed Global Harmonization System (GHS) sign perception and the safety culture questionnaires in this survey. Data were analyzed using regression and Pearson correlation tests.
This study showed that the participant's correct perception in nine cases (81.8%) of presented GHS signs was lower than the ANSI Z535.3 standard. Among the investigated signs, "Flammable substances" and "Harmful to the environment" signs had the highest, and "Skin irritant" signs had the lowest correct perception. In addition, it was found that 55 people (80.9%) had an overall positive attitude toward the safety culture. The levels of "Work environment" (83.8%) and "Information exchange" (76.5%) had the highest and lowest positive scores for safety culture. Furthermore, there is a direct and significant relationship between the overall score of safety culture and the overall perception of the symptoms of GHS (CC = 0.313, P = 0.009).
According to the obtained results, it is recommended to take the necessary measures to increase the employees' perception of the signs of chemical substances and improve their safety culture.
•This research is the first study to theorize and evaluate hospitality employees’ safety performance behaviors.•This research finds the boundary role of communication transparency in the link between ...safety climate and safety motivation.•This research provides empirical evidence regarding the boundary role of safety-related stigma on hospitality employees’ motivation and behaviors.•Mediation mechanism between safety motivation and safety performance behaviors was explained by prevention work focus.•Hypotheses were tested using data from two different counties (South Korea and the United States) to bolster the generalizability and the robustness of the findings.
This study develops and tests a research model to explain and predict how and when organizational safety climate influences hospitality employees’ safety performance behaviors by proposing two boundary conditions: communication transparency and safety-related stigma based on expectancy-valence theory. Specifically, we examined if communication transparency intensifies the impact of perceived safety climate on employees’ safety motivation that drives safety performance behaviors through prevention work focus and if safety-related stigma attenuates the links between safety motivation and safety performance behaviors. Based on two national samples of 214 South Korean and 240 U.S. foodservice employees, this research found that safety climate was positively associated with safety motivation, prompting safety behaviors with the key mediating mechanism of prevention focus work. However, there were different patterns observed for the moderating roles of communication transparency and stigma for the foodservice employees between South Korea and the United States. Implications of the findings are discussed for hospitality researchers and practitioners.
The construction industry has one of the highest frequencies of work-related accidents. We examined whether construction workers predominantly identify themselves in terms of their workgroup or in ...terms of the construction site. In addition, we examined the associations between social identity and safety climate, and how these constructs are associated with work-related accidents. The analyses were based on questionnaire responses from 478 construction workers from two large construction sites, and the methods involved structural equation modeling. Results showed that the workers identified themselves primarily with their workgroup, and to a lesser degree with the construction site. Social identity and safety climate were related both at the workgroup and construction site levels, meaning that social identity may be an antecedent for safety climate. The association between social identity and safety climate was stronger at the workgroup level than at the construction site level. Finally, safety climate at both levels was inversely associated with self-reported accidents, with the strongest association at the workgroup level. A focus on improving safety climate, particularly by integrating initiatives at both the workgroup and management level, may have the potential to improve safety performance and thus decrease the risk of accidents and injuries on construction sites.
•A comprehensive and critical review is conducted of CV applications.•Construct and visualize bibliometric networks to review literature.•A contents analysis method is used to quantitatively review ...literature.•The limitations of existing studies and future research directions are discussed.
Globally, the occupational health and safety (OHS) of construction workers has long been a serious concern. To address this issue, there is an urgent need for an efficient means to continuously monitor the construction site to eliminate potential hazards in a timely manner. As robust and automated video and image information extraction and processing tools for construction sites, computer vision techniques have been considered to be effective solutions and been applied for the occupational health and safety monitoring of construction site workers. This paper aims to use bibliometric and content-based analysis methods to review the previous attempts in related fields and present the current research status in this field. The results clarify the major limitations and challenges of the current research from both technical and practical perspectives, in turn suggesting the direction of future research.
To promote safety culture assessment, this paper developed China's first online safety culture analysis and evaluation system—Safety Culture Analysis Program (SCAP). SCAP is based on the 32 safety ...culture elements in the 24Model and provides two login methods: web version and WeChat mini program. It can meet the needs of individuals, groups, and enterprises to conduct safety culture assessments anytime and anywhere and provide convenience for universities to conduct safety culture experiments. The application of SCAP showed that (1) SCAP has rich functions and is highly scientific and universal. (2) The SCAP can output assessment results according to categories, such as total, personnel, safety culture elements, and individual employee requirements, which can be compared with the highest and lowest values stored in the system. This makes it easy for intuitively understanding the current evaluation status. (3) The suggestion report generated by SCAP can help assessment units improve safety culture in a targeted manner and form a dynamic mechanism cycle of “construction-evaluation-construction.” (4) In the future, SCAP will be employed in designing more targeted questions based on the characteristics of different industries and fields to balance the adaptability and specificity of the industry.
•Chinese enterprise safety training was conducted in accordance with the “Regulations on Safety Training for Production and Business Units”. Its regulations on safety training content are considerably broad and lack guidance for industrial safety training.•The ACDACM combines historical accident cases and accident causation models, making the developed safety training program comprehensive and in line with industrial needs. The safety training program was established based on this method, which consists of eight parts, each supported by historical data.•It is necessary to build an industry database based on the ACDACM method and a national security training database (system), which can achieve “development of safety training content - safety training learning - safety training assessment - safety training reporting.
•An optimal width allocation policy for traffic lanes and footpaths is developed.•Optimal lane width is 5.4 m when user and agency costs are equally important.•Hong Kong road agency places a higher ...weight on each dollar of user cost.•Allocation to footpaths can reflect the importance placed on pedestrian safety.
Introduction: Walkability continues to attract great attention from urban planners, designers, and engineers as they recognize not only the merits of pedestrian facilities in terms of the health benefits but also their demerits in terms of accident risk to pedestrians. Wide footpaths improve the pedestrian environment and experience, and thereby motivate travelers to walk as much as possible. However, if footpaths are too wide, they may leave a smaller space for the roadway. On the other hand, wide road lanes may lead to higher road vehicle safety but are costly to construct and maintain and also may leave little space for the footpath. Evidently, for a fixed urban space, what is needed is an optimal balance between the vehicle lane and pedestrian path. This problem is encountered routinely in dense cities including Hong Kong where land availability is severely limited. Method: To address the issue, this paper first establishes safety performance functions (SPFs) for the pedestrian space and the road space, using the random-parameter negative binomial regression. The results indicate the extent to which road lane and footpath width changes are associated with changes in in-vehicle occupant and pedestrian casualties. Then the paper uses the SPFs to develop a methodology for optimizing the width allocations to the road lanes and footpaths, duly considering the user (safety) costs and agency (construction) costs associated with each candidate allocation of the widths. Finally, the paper analyzes the sensitivity of the optimal solution to the relative weights of user cost and agency cost. Results: When user and agency costs are considered equally important, the optimal lane width is 5.4 m. Conclusion: It is observed that the road space allocation ratio used by the Hong Kong road agency suggests that the agency places a higher weight to user cost compared to agency cost. Practical Application: The findings can help incorporate design-safety relationships, and the stakeholders (agency and users) perspectives in urban road and footpath design.
