By increasing the number of mineral industries in the two past decades, workers in these industries are exposed to pathogenic respirable particulate matter pollutants. Cluster analysis is a multivariate statistical analysis method. Clustering creates groups or classes that the difference between the sub-groups samples is less than the difference between the groups. Therefore, this study assigns the cluster analysis to air sampling data collected from the various units of a tile factory. Methods: In this observational study, sampling from the respiratory zone of 93 workers in a tile and ceramic factory for both respirable and inhalable particles were performed. Sampling of inhalable particle based on NIOSH_0500 protocol and respirable particles based on NIOSH_0600 was conducted. Data were analyzed by both R 3.2.2 software and hierarchical cluster analysis with Ward link. Results: 92.47% of Workers were exposed to respirable particles less than TLV and 39.8% of them were exposed to inhalable particles more than TLV. The maximum average exposure for respirable particles 13.04 mg/m3 and inhalable particles 84.88 mg/m3 is respectively reported for crusher unit. The lowest average exposures to respirable (0.41 mg/m3) and inhalable (min=1.74 mg/m3) particles were observed in the glaze line division. Conclusion: Since the workers are exposed to concentrations more than the threshold limit value of respirable particles, and especially inhalable particles in some units, appropriate control measures must be considered to prevent possible consequences","PeriodicalId":32672,"journal":{"name":"Archives of Occupational Health","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45389718","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}

Welding is one of the jobs whose professionals may expose ultraviolet and infrared radiation and suffer from the resulting complications. Therefore, the purpose of this study is to determine the exposure to ultraviolet and infrared radiation in welders. Methods: This study was conducted on 70 welders in Bojnord city. The UV meter and the IR meter (Hanger) were used to conduct measurements. The measurements were conducted at 10, 50 and 100-cm distances from the welding site, and at two heights, the wrists and eyes. Eye symptoms caused by radiation were collected and recorded by checklist and observation. Data were analyzed by descriptive statistics, t-test, and ANOVA. Results: The average age of the workers was 37(10) years, the average work experience was 18(11) years, and the average radiation exposure duration was 3.5(2) hours. The average ultraviolet radiation measured was 4.13(4.88) W/m2 and the average infrared radiation was 17.13(12.54) W/m2 at the welding stations. In 84% of the stations, the measured ultraviolet radiation and in 100% of them, the measured infrared radiation was standard. There were 58 (83%) welders with at least one eye problem. There was a significant relationship between the amount of radiation, and the type of welding, exposure duration, and work history, but no significant relationship between the amount of radiation and height and distance of measurement. Conclusion: In order to prevent eye symptoms in welders, it is recommended to reduce the duration of exposure of the welders or welders should do welding during the day intermittently and use suitable personal protective equipment, especially a suitable welding mask, during welding.","PeriodicalId":32672,"journal":{"name":"Archives of Occupational Health","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49370352","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}

However, the health and safety conditions of this industry are in an unfavorable status, and these conditions have caused a lot of accidents. In this regards, one of the most important ways to prevent accidents in this industry can be identifying hazardous points and adopting appropriate control measures. The aim of the study was to identify hazardous points in foundry industry using a hybrid safety approach. Methods: This descriptive-analytic study was conducted in the foundry industry of Iran, in 2016. The study method consisted of two parts. First, the accidents of foundry were analyzed. Second, the Energy Trace and Barrier Analysis (ETBA) technique was used to identify hazards and assess the risks. The collected and obtained data of accidents and risk assessment were entered into the statistical SPSS software, version 22, and descriptive statistics (mean, percent) were used for analyzing. Also, Microsoft Excel was used to plot the graphs. Results: A total of 128 risks is identified, including 17 unacceptable risks, 93 undesirable risks, 13 acceptable risks with revision and five acceptable risks without revision. The mechanical and physical energies had the highest percentage of hazards. The results of accidents analysis showed that the cause of most accidents (40%) was mechanical, while 23% of them was the potential type. The study results indicated that accidents analysis along with risks identification can be useful in identifying all the dangerous locations (points). Conclusion: In addition to validating the results of risk assessment through the analysis of accidents, other causes affecting the occurrence of accidents can also be covered by accident analysis, including unsafe behaviors and organizational causes that are not seen in the risk assessment.","PeriodicalId":32672,"journal":{"name":"Archives of Occupational Health","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41324742","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}

In this regards, simultaneous application of several models in a project and comparing the results obtained from these models could have been a considerable contribution to air quality managers for taking a more efficient decision. Methods: In this study, the stack of an industrial plant in the southwest of Isfahan was selected as the emission source and the total suspended particles emitted from this stack was simulated by applying AERMOD and ISCST3 view models (version 8.2). In this vein, the modeling process was conducted using MM5 meteorological data in a 50 50 km extent with 2000 m network distance for each of the models in 1-h, 24-h term averages (short term averages) and monthly and annual periods (long term averages) at ground level concentrations (GLC). Results: Results indicated that the highest simulated concentration for both models occurred in a 2000 meters’ distance in the east of the stack. Moreover, the highest simulated concentration applying AERMOD was lower than that of applying ISCST3 in all term averages which is due to existing differences between applied algorithms in these two models. Conclusion: Consequently, applying AERMOD due to the use of more advanced and up-to-date algorithms have priority over ISCST3 model. Applying ISCST3 can also be useful for small projects that require less input data compared to the AERMOD.","PeriodicalId":32672,"journal":{"name":"Archives of Occupational Health","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48021022","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}
