    A collaborative framework by the synergy of Hazard and Operability (HAZOP) process and the Decision-Matrix Risk Assessment (DMRA) in association with safety-color mapping (SCM) is presented, in order to identify critical points and prioritize risks, and also to visualize the occupational safety and health (OSH) situation, at the workplaces (i) of a sour crude-oil processing industry (SCOPI), and (ii) of a measurement and regulatory station (MRS) in a gas transportation system (GTS), situated in Greece. Firstly, the conventional HAZOP analysis is executed in order to identify the potential fault causes of abnormal conditions (deviations) in the plants. The application of the DMRA-modus is valuable to rank the identified risks (hierarchy of risks). In view of the results, both of the HAZOP pattern (for identifying the hazards) and also the DMRA one (for assessing and ranking the risks), SCMs have been derived for the specific workplaces of the SCOPI and the MRS/GTS station, which could be a precious means for safety managers to appraise the urgency of investing limited budgets in measures preventing particular types of deviations, and also protecting the employees

    This study, on the one hand, develops a newfangled risk assessment and analysis (RAA) methodological approach (the MCDM-STO/DET one) for sustainable engineering projects by the amalgamation of a multicriteria decision-making (MCDM) process with the joint-collaboration of a deterministic (DET) and a stochastic (STO) process. On the other hand, proceeds to the application of MCDM-STO/DET at the workplaces of the Greek construction sector and also of the fixed-telecommunications technical projects of OTE SA (that is, the Greek Telecommunications Organization S.A.) by means of real accident data coming from two official State databases, namely of “SEPE” (Labor Inspectorate, Hellenic Ministry of Employment) and of “IKA” (Social Insurance Institution, Hellenic Ministry of Health), all the way through the period of the years2009–2016.Consequently, the article’s objectives are the following: (i) The implementation and execution of the joint MCDM-STO/DET framework, and (ii) to make known that the proposed MCDM-STO/DET algorithm can be a precious method for safety managers (and/or decision-makers) to ameliorate occupational safety and health (OSH) and to endorse the sustainable operation of technical or engineering projects as well. Mainly, we mingle two different configurations of the MCDM method, initially the Analytical Hierarchy-Process (the typical-AHP), and afterwards the Fuzzy-Extended AHP (the FEAHP) one, along with the Proportional Risk Assessment Technique (PRAT) and the analysis of Time-Series Processes (TSP), and finally with the Fault-Tree Analysis (FTA)

    Recently, the seamless construction and operation of natural gas pipelines has become even more critical, while the oil and gas industry’s capability to operate effectively with acceptable risks and hazardous situations is mainly dependent on safety. As a result, it is very important to have a wide knowledge of effective management tactics for enhancing implementation of safety regulations and procedures. The problem of assuring workers’ health and safety in the workplace is a crucial component in the endeavor to raise the productivity of labor and the level of competitiveness of building projects. To promote the health, safety, and well-being of workers, issues that are embedded within the concept of sustainability, we propose in this study a safety risk-assessment process that uses the analytical hierarchy process for assigning priorities to risks on construction worksites. This process uses a popular multicriteria method. The success of this strategy was shown by its application to the building of a natural gas compressor plant in Greece. The main contribution of this study is the application of a well-known multicriteria method for assessing risks in a natural gas compressor station construction project and prioritizing hazards to allocate budget for risk-mitigation measures

    Multicriteria Health and Safety Risk Assessments in Highway Construction Projects

    Road building sites are no exception to the fact that construction is one of the most dangerous businesses in the world. There are a number of concerns about the health and safety of the workers at these sites since they combine personnel, machinery, and construction equipment. The purpose of this paper is to determine, analyze, and compare the risks present at road building sites, and how they affect the health and safety of the workers. The study also examines workplace stress and psychosocial risk factors, which may have long-term effects on workers’ physical and mental health. To meet the goals of the research, risk evaluations for a specific construction project were carried out using the Analytic Hierarchy Process (AHP). Using the risk categories and risk factor hierarchy, the AHP compares data pairings. The skills, experience, judgments, and value system of the decision-makers were taken into account while deciding the amount of importance to give each criterion. The final risk rankings were established after calculating the overall priority numerically and running the necessary judgment consistency tests. The most significant risks to the health and safety of workers at road construction sites were identified by the study’s findings. The study additionally showed that psychosocial risk factors were important contributors to workplace stress and may have a negative impact on employees’ health and wellbeing. The results of the present study have important implications for risk management practices in the construction industry. Project managers can implement effective mitigation measures to reduce the likelihood and severity of accidents and injuries by identifying and evaluating the most critical risks associated with road construction sites. The findings also highlight the importance of addressing psychosocial risk factors and workplace stress in improving workers’ health and safety outcomes. Overall, this study underscores the need for a comprehensive approach to risk management that considers the diverse and complex factors contributing to construction site hazards
