One of the systems use to measure safety performance is occupational safety and health audit which identify failures within a system and the information gathered assist to determine the best course of corrective action. Therefore, this study was designed and conducted to develop a method for evaluating the safety performance of five highway project sites in India using the Analytic Hierarchy Process and Taguchi loss functions. In the first stage of the study, the Analytic Hierarchy Process was applied by obtaining the judgments of the expert team to determine the weights of the safety audit elements. In the second stage, the five project sites were analyzed and ranked by determining the total loss score using the Taguchi loss functions. Based on the Analytic Hierarchy Process analysis, the weights of the safety management (0.1949), hazard identification and risk assessment (0.1460), and safety education and training (0.1268) had the highest impact on the safety performance of the five project sites. The results of the Taguchi loss functions of the five project sites showed that the total loss score was the lowest and highest for project site 3 (77.89) and site 5 (81.54), respectively. In the current study, an integrated method was developed for evaluating the safety performance of five highway project sites. The weights of the nine safety audit elements were vital in determining the total loss score by using the Taguchi loss functions for ranking the five projects sites based on safety performance. Therefore, using this method can be an effective step in identifying the project site with better safety performance as a benchmarking unit for the other sites.","PeriodicalId":52667,"journal":{"name":"International Journal of Occupational Hygiene","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42941605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate the effect of integrated management systems (IMS) establishment on safety performance improvement. This study was a retrospective study conducted at the Mazrouf Glass factory in Yazd, Iran. To investigate the effect of IMS establishment on the safety performance during the studied years, indices of injury frequency rate (IFR), injury severity rate (ISR), frequency-severity index (FSI), and Safety T. Score (S.T.S) were used. The paired-samples t-test was used to compare safety indices before and after the establishment of the IMS. The results showed that the establishment of IMS had a meaningful effect on the reduction of the IFR and ISR. Also, no meaningful effect was found between IMS establishment and FSI and S.T.S. IMS establishment could reduce the IFR and ISR, which in turn may promote productivity indicators. Eventually, it could be concluded that IMS establishment can be used as an effective proceeding to improve workplace safety indices. \u0000 ","PeriodicalId":52667,"journal":{"name":"International Journal of Occupational Hygiene","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46187547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evaluating the environmental performance in ports as one of the two main parts of the maritime transport system is of particular importance. Therefore, the current study was designed and conducted to develop a method for evaluating the environmental performance of ports based on the fuzzy analytic hierarchy process (FAHP). In the present study, 22 experts in the field of environment and marine sciences were selected in 2020. Firstly, various studies on the factors affecting the environmental performance of ports were reviewed. Secondly, a questionnaire was designed to assess ports’ environmental performance. Thirdly, this questionnaire was developed using the Delphi technique. Finally, by determining the weight of each parameter, the method of environmental performance assessment in ports was developed based on the FAHP. The final normalized weights for six environmental performance factors including reactive and proactive performance, sustainability, socio-cultural, economic, and governance were estimated 0.202, 0.241, 0.226, 0.070, 0.080, and 0.182. Additionally, it was found that each of the parameters had a different weight and impact on these factors. The highest and lowest impact on the environmental performance index belonged to environmental risk assessment (weight=0.217), cultural effects, and justice (weight=0.107). In the current study, a new method was developed for evaluating the environmental performance of ports based on six factors, 32 parameters, and FAHP. Therefore, this method may provide an effective step in reducing environmental impacts and improving the level of environmental performance in ports to achieve the goal of green port.","PeriodicalId":52667,"journal":{"name":"International Journal of Occupational Hygiene","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42079442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the safety and health authorities in organizations, safety and health is the general responsibility of all other experts working in an organization. Experts and managers are expected to think, decide and work safely in workplaces. However, we don’t have enough information about the level of safety and health-related education when they were in universities. In addition, there is not too much reliable published reports on the academic teaching of safety and health courses and syllabus in higher education in Iran. Therefore, the current study was aimed to provide a general view of the status of occupational safety and health teaching subjects in different academic disciplines (excluding specialized fields in occupational safety and health) in the Iranian higher educational system. Firstly, the latest edition of the entire program (curricula) of all academic disciplines held in Iranian universities was downloaded. Secondly, the required information, including discipline title, program’s degree, number of required (core) and elective (non-core) courses, and program’s date of approval, were recorded in an Excel sheet. Every course’s title and syllabus were then studied to find out any safety and health-related topics. Finally, data were analyzed and reported. 251 academic disciplines in the Ministry of Health and Medical Education (MOHME) and 771 disciplines in the Ministry of Science, Research and Technology (MSRT) were investigated. Most of the curriculums have been revised by both ministries since 2011. Results showed that 20 percent of the MOHME‎ ‎disciplines and 10.4 percent of MSRT‎ disciplines were included in the occupational safety and health courses. The number of courses with health and safety content (syllabus outline) in the MOHME ‎‎and the MSRT‎ were 168 and 173. Most health and safety courses presented in the MOHME academic majors were in the basic medical sciences category of disciplines. A majority of MSRT covered academic safety and health courses and topics were presented in the engineering category of disciplines. Presenting lessons with health and safety content at the MOHME ‎was more practical than that of the MSRT. The quality and quantity of teaching on safety and health topic were not at satisfactory levels. Revising the course syllabus of the academic disciplines and adding theoretical and practical courses related to each field's specific health and safety curriculum can make a significant contribution in improving the general knowledge of the safety and health of the university graduates. In turn, it improves future workplace safety and health conditions, managers’ insights and decision-makers on the importance of safety and health at work. It protects the people's life and the property of the organization.","PeriodicalId":52667,"journal":{"name":"International Journal of Occupational Hygiene","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45411844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human reliability analysis (HRA) has drawn a great deal of attention among safety engineers and risk assessment analyzers. Despite all technical advances and the development of processes, damaging and catastrophic accidents still happen in many industries. Human Error Assessment and Reduction Technique (HEART) and Cognitive Reliability and Error Analysis Method (CREAM) methods were compared with the hierarchical fuzzy system in a steel industry to investigate the human error. This study was carried out in a rolling unit of the steel industry, which has four control rooms, three shifts, and a total of 46 technicians and operators. After observing the work process, reviewing the documents, and interviewing each of the operators, the worksheets of each research method were completed. CREAM and HEART methods were defined in the hierarchical fuzzy system and the necessary rules were analyzed. The findings of the study indicated that CREAM was more successful than HEART in showing a better capability to capture task interactions and dependencies as well as logical estimation of the HEP in the plant studied. Given the nature of the tasks in the studied plant and interactions and dependencies among tasks, it seems that CREAM is a better method in comparison with the HEART method to identify errors and calculate the HEP. \u0000 ","PeriodicalId":52667,"journal":{"name":"International Journal of Occupational Hygiene","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42247006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
