Hazards are a potential source of harm and damage hiding in shadow zones. Without control, they may accumulate and interact with other types of hazards. In the harsh and complicated circumstance, especially, the deep underground space of coal mines, complex and nonlinear interactions among hazards multiply the probabilities that a hazard turns into accidents, more seriously, its effect may trigger more correlated hazards to worsen the accidents and bring huge loss of lives and assets. Therefore, identifying the correlations among hazards and understanding the complexity of interactions among coal mine hazards are significant for ensuring the safety of coal production. From this standpoint, we propose a hybrid method combing text mining and complex network method. First, we abstract the dangerous hazards from a large amount of text data. Then, we establish the coal mine hazard network (CMHN) to capture correlations among hazards. Finally, we analyze and predict the correlations among hazards based on CMHN. Through which, we find the fault-prone hazard and the recurrent hazards, more importantly, we figure out the nonlinear correlations among hazards and reveal the connection preference of hazards. Furthermore, we forecast the unknown correlations among hazards to take precautions of them. This study could be helpful for making prevention strategies for safety management in the coal mine and other highly dangerous industries.
Occupational safety and illness surveillance has made a great effort to spread a "safety culture" to all workplaces and a great deal of progress has been made in finding solutions that guarantee safer working conditions.This paper analyses occupational injury data in order to identify specific risk groups and factors that in turn could be further analyzed to define prevention measures.
A technique based on rule induction is put forward as a non-parametric alternative tool for analyzing occupational injury data which specifically uses the Classification And Regression Tree (CART) approach. Application of this technique to relevant work-related injury data collected in Italy has been encouraging. Data referring to 156 cases of injury in the period 2000–2002 were analyzed and lead to the factors that most affect work-related injuries being identified.
According to the literature, up to the time of writing computer-intensive non-parametric modeling procedures have never been used to analyze occupational injuries. The aim of this paper is to use a real world application to illustrate the advantages and flexibility of applying a typical non-parametric epidemiological tool, such as CART, to an occupational injury study.
This application can provide more informative, flexible, and attractive models identifying potential risk areas in support of decision-making in safety management.
The ongoing expansion of power grid infrastructure has led to more complex line configurations and increased operational intricacies. Presently, there’s a noticeable gap in targeted, categorized analysis of operational factors influencing the risks and compliance issues in distribution network operations. The challenge in prioritizing and assessing these risks is compounded by the lack of measurable indicators, posing safety risks at operational sites. This study presents a comprehensive analysis of risk factor dimensions in distribution network operations and introduces measurable indicators for these risks. We propose a three-level risk assessment framework for distribution network operations, categorizing risks associated with personnel, the operational environment, equipment and management shortcomings. The Analytic Hierarchy Process (AHP) is utilized to determine the weights of 34 specific risk indicators within this framework. Furthermore, we explore the implementation of this risk assessment model, considering the real-world conditions of distribution network management centers, operational sites and inspection equipment. The practicality of the proposed framework and methods is validated through a case study of a power supply bureau’s distribution network operations. This research aims to enhance the safety risk management strategies in power grid companies, offering insights for improving on-site operational risk control in these enterprises.
In the construction industry, safety has always been a persistent issue. The importance of safety knowledge for construction was highlighted by literature and practices. This study aimed to understand safety knowledge management (KM) commitments, strategies, and tools being used in Indian construction organisations. A survey was conducted among safety managers/heads in eight leading Indian construction contractors operating in a global construction market. The results indicated that out of eight companies, safety KM systems were available in seven companies and one was looking to implement it. All the organisations consider safety KM as the strategic assets for their companies and were aware of safety KM’s benefits. Email, Internet, small-group meetings and brainstorming were considered the most important tools to transfer safety knowledge among these organisations. Out of eight, six contracting organisations were aware that costly errors occurred at their companies when safety knowledge was not available when and where it was needed. Hence, safety knowledge sharing culture should be cultivated to enhance the safety performance of contracting companies. The findings may be used to establish standards to facilitate safety KM as an initial point for the government. This study would serve as a foundation for companies to enhance safety performance by improving their safety KM systems.
As blockchain technology and smart contracts develop, computer technology is constantly integrating with smart chemical plants. Due to the continuous development of intelligent chemical plants, their systems have gradually become large and dispersed, posing a threat to safety management. In order to improve the performance of intelligent security management systems, the study first explores the principles of blockchain and smart contract technology, and then combined with the requirements of intelligent chemical plant security management systems, designs an intelligent security management system based on blockchain and smart contract technology. The experimental results showed that compared to systems without smart contract support, the communication success rate between nodes was lower. The error rates of blockchain-based encryption systems, deep learning-based encryption systems and improved data encryption systems proposed in the study were 0.22, 0.07 and 0.09, respectively. The packet loss rates were 0.13, 0.04 and 0.05, respectively. The lower the bit error rate and packet loss rate of the encryption system, the clearer the illegal eavesdropping information. The experimental results indicate that the intelligent security management system designed in this study has good encryption performance and a higher communication success rate. The results have certain reference value in security management application in intelligent chemical plants.
The Balanced Scorecard is strategic management tool that effectively combines financial and non-financial measures to guide strategy development, implementation and communication. It provides a means of identifying links between strategic objectives and concrete measurements throughout an organization. This paper investigates the possibility of adapting this tool to measure organizational safety culture in construction. The paper argues that this tool provides a medium to translate the organization's safety policy into a clear set of goals across four perspectives (management, operational, customer and learning). These goals are then further translated into a system of performance measures that effectively communicates a powerful strategic focus on safety to the entire organization. Four perspectives have been developed to represent all stakeholders, thereby ensuring that a holistic view of safety is used for strategic reflection and implementation. The paper argues that by selecting and evaluating the appropriate measures, in each perspective, requirements can be identified and actions to the identified goals can be aligned and facilitated. Finally, the paper reports on an exploratory study aiming to test the potential applicability of the proposed tool.
A comprehensive research for defining the organizational aspects of a construction contractor's subsystems was performed to provide these contractors with benchmarks for evaluating their subsystems. This paper describes the organizational aspects of contractors' safety management subsystems. The objective of this research was accomplished by surveying the literature, and by contacting twenty one construction industry experts through a comprehensive structured questionnaire. The research results define the organizational aspects of a safety management department in terms of key functions, location in the organization, key personnel, safety management tools, link with other departments, safety management program, and safety management effective practices. If a contractor implements the study recommendations to its safety management department, he would realize working and efficiency improvement in the safety.
