Commercial buildings are considered as high‐risk units in fire due to the existence of expensive equipment and large presence of people with different ages. Therefore, the present study aimed to assess the fire risk of commercial and shopping centers in Kashan using the fire risk assessment method for engineering (FRAME). This cross‐sectional study was conducted using FRAME in 15 commercial and shopping centers in Kashan, Iran. The risk assessment data and FRAME checklist were collected by observation and interviews. Data analysis was conducted using Excel and Geographic Information System (GIS) software. The results of 46 checklists showed that the mean score of fire risk R for property was equal to 3.12, for people 3.81 and for activities 1.86. Also, the lowest risk for the property, people and activities belongs to Golestan Center with a score of 1.40, Valiasr with a score of 1.25 and Ataee with a score of 1.15, and the highest risk for the property, people and activities belongs to Mir Seyfi Center with a score of 5.80, Shafagh with a score of 9.96 and Sabz was 2.62, respectively. The present study showed the lack of proper ventilation system, lack of emergency exits, and lack of automatic fire alarm and extinguishing system were the factors affecting fire risk. Therefore, in order to prevent disasters and uncontrollable critical conditions, it is necessary to review the equipment of these buildings and to design and implement fire detection and alarm equipment and different ways of fire control in these centers.

Aim: Unsafe behaviors (UBs) are the most important cause of accidents, so there is a need to identify the factors effective on it. The purpose of this study was to identify the factors affecting the occurrence of UBs and also to build a strong theoretical model with fuzzy logic. Materials and Methods: This study was conducted among 270 participants in the steel industry in Iran. The factors, such as work-family conflict, job stress, and general health were investigated using relevant questionnaires, and the prevalence of UBs was investigated with the safety behavior sampling technique. Finally, the results were analyzed with SPSS 21.0 and MATLAB software. Findings: The results showed that out of 1310 samples of observed behavior, 531 UBs were observed (39.81%). There were 202 cases of nonuse or inappropriate use of personal protective equipment. General health, job stress in the supervisor, and colleagues' support were significantly associated with UBs (P < 0.05). In addition, general health, work-family conflict, job stress and were significantly correlated with each other (P < 0.001). Diffuse results using fuzzy logic predicted 56% of the behavioral conditions. Conclusions: This study showed that managing UBs is possible by controlling factors such as the support of supervisors and the way of management, as well as the reduction of social stresses such as work-family conflict, in addition to being able to increase people's health, also reducing accidents and UBs. Finally, using fuzzy logic, it is able to predict reality, and by knowing several behaviors, better models can be obtained. [ABSTRACT FROM AUTHOR]

BACKGROUND: Surgeon's hands are exposed to a range of chemical and physical stressors that influence the integrity of gloves. Thus, glove perforation facilitates pathogen transmission through the holes. Numerous studies have shown that glove perforation is of great importance, but there is still no complete consensus. OBJECTIVE: This study aimed to investigate the safety conditions of surgical gloves based on the incidence of glove perforation among surgical teams. METHODS: A literature review was conducted by searching PubMed, Embase, Scopus, ISI, and ProQuest databases. The incidence of glove perforation was reviewed in eight categories. A total of 580 articles were found in the initial search. RESULTS: 109 articles containing 130 datasets were analyzed. The overall incidence of glove perforation was 14.44 %. Surgeons had the highest incidence of glove perforation (23.09 %). An increase in the duration of surgery increased the odds of perforation. It was found that 68.58% of the glove perforations were not identified by practitioners. CONCLUSION: Despite major advances in the design of surgical gloves, the issue of safety and integrity of gloves has not improved. Due to the high incidence of surgical glove perforations, most of which had not been identified, it is imperative to consider strategies to minimize the incidence of perforation. The results of the present study can be used to integrate information related to the rate of perforation of surgical gloves in different surgeries. [ABSTRACT FROM AUTHOR]

Aims: Fatigue is a state in which a person's energy is completely depleted due to excessive physical or mental work. In addition to the importance of women workers and the effects of fatigue on them, limited studies have been conducted in this field in the world, especially in Iran. The present study was conducted to investigate the prevalence of fatigue and related factors among women workers in one of the cities of Iran. Materials and Methods: A cross-sectional study was performed among women workers in Kashan in 2018. The sample size was 265 participants from 300 workers. The data collection tool was the multidimensional fatigue inventory questionnaire. Data were analyzed via SPSS version 16. Results: The lowest and highest total score was 38 and 78, respectively. The mean score of activity decrease was 11.78, which was the highest score among questionnaire. Factors such as overtime, number of children, and work experience showed a statistically significant relationship with the total fatigue score (P < 0.05). Conclusion: According to the results, a large percentage of participants had a high score of fatigue. Managements should identify and modify the factors affecting fatigue to reduce the worker's fatigue. It seems that further studies are needed to reveal the relationship between fatigue and other variables to provide a deeper understanding of the causes of fatigue. [ABSTRACT FROM AUTHOR]

Aims: Environmental conditions affect workers health and performance. The present study aimed to investigate the simultaneous effect of ambient temperature and light intensity on human error. Materials and Methods: This cross-sectional study was conducted on 50 students from Shiraz University of Medical Sciences. Each participant performed 9 tests in 5 min at 3 different temperatures (20°C, 25°C, and 30°C) and 3 lighting conditions (50, 500, and 1000 lux). The participants were asked to select a text randomly. Participants asked to read the text in just 6 min and identify the mistakes. In each step, the number of remaining lines, number of spelling mistakes found, and task completion time were estimated. Results: There was no significant relationship between the temperature and the number of remaining lines, the number of spelling mistakes, and the task completion time (P > 0.05). However, the relationship between different light intensity and the number of remaining lines and number of spelling mistakes was statically significant (P < 0.05). At a lighting of 500, 1000 lux, and a temperature of 25°C, male subjects performed better. Unlike men, women's performance was not affected that much by the light intensity and only declined slightly in the 1000 lux and at 20°C. Conclusions: The results showed that light intensity could be important to create a suitable environment for reducing human error. If the temperature could not increase in an environment due to the nature of a job or economic issues, reducing human errors could achieve by increasing light intensity. [ABSTRACT FROM AUTHOR]

Aims: Latex sensitivity has been a concern for health-care workers in recent years. Due to the excessive exposure to latex products in the operating room, the personnel of this department are exposed to high sensitivity to these products. Therefore, the present study was conducted to investigate the prevalence of latex sensitivity among operating room personnel. Materials and Methods: This systematic review and meta-analysis conducted based on a Preferred Reporting Items for Systematic Reviews and Meta-Analysis checklist. The present study researchers explored four international databases, namely Medline/PubMed, ProQuest, Scopus, and Embase in February 2020. The selected keywords for international databases were classified into three categories (a) operating room personnel, (b) latex sensitivity, and (c) prevalence. The collected data were entered into the EndNote X8 software and analytical analysis was performed by STATA statistical software version 12. Results: Seventy-five articles were found by searching for databases. After several screening steps, 12 articles entered the final analysis. The results show that the prevalence of latex sensitivity in total is 14.76 (confidence interval 95%: 9.27–20.25). Meta-regression results showed that the relationship between the years of study and the prevalence of latex sensitivity is not statistically significant (P = 0.222). Conclusion: The results of the present study showed that sensitivity to latex is significantly prevalent among operating room staff. Due to the importance of sterility and sensitive working conditions in the operating room, as well as frequent contact with latex products, it is important to pay attention to the side effects caused by latex powder.

Aims: A most widely used tool for measuring the workload is the NASA-task load index (TLX) questionnaire, in which various studies have reported numerous problems. The present study aimed to improve the NSAS-TLX mental workload questionnaire using the fuzzy linguistic variables instead of the virtual rating scale, and multicriteria decision-making Fuzzy Best-Worst method (FBWM) instead of pair-wise comparison. Materials and Methods: This cross-sectional study was carried out among students of Shiraz University of Medical Sciences. In order to compare the traditional NASA-TLX and FBWM NASA-TLX questionnaire, participants performed a standard N-Back task with three low, medium, and high workload, subsequently, they completed the two questionnaires. Finally, results were examined using the researcher-made software and SPSS 16. Results: With regard to the reaction time to response the N-Back test, the mean of correct responses were 107.43 and 85.86 responses at levels 1 and 3, respectively. The mean score of the subscales and the final score in the two questionnaires at different levels of the N-Back test were independent as follows: the two questionnaires had a significant difference on mental demand at level 3 with a mean (standard deviation [SD]) of 18.09 (6.39) in the FBWM-NASA-TLX questionnaire and mean (SD) of 22.64 (8.15) in the NASA-TLX questionnaire (P < 0.05). Conclusion: In this study, the FBWM-NASA-TLX questionnaire was designed and studied with regard to the problems and limitations of the NASA-TLX questionnaire. Results of this study showed that the FBWM-NASA-TLX questionnaire can estimate more realistic scores and decisions of workload in the studied task. [ABSTRACT FROM AUTHOR]

Background: Drivers are vulnerable to musculoskeletal and psychological disorders because of substantially harmful agents in this stressful occupation. This study aims to investigate the influence of driver's physical and psychological health on the risk of road accidents using fuzzy logic approach. Methods: Two input variables including musculoskeletal disorders (MSDs) and mental health, alongside accident risk levels as output variables were fuzzed using a fuzzy inference system (FIS). Triangular and trapezoid membership functions were used to graphically define outputs related to low, moderate, high and very high, in fuzzy sets. A Mamdani-type FIS was applied to represent all the rules in the IF-THEN format and the patterns of linguistic variables were designed using AND, OR and NOT operators. Results: The results showed that there is significant relationship between MSDs and psychological health with road accidents involving drivers of heavy vehicles (p<0.05). Also, surface graphs illustrated the relationship between MSDs, psychological health and accident risks. FIS as a novel approach was used for predication of accident risk levels involving drivers of heavy vehicles on the basis of health factors. Conclusions: Physical and psychological health can influence the safe operation of heavy vehicle drivers. The fuzzy inference system provided a method that is advantageous and with promising results for modeling of road accident risk levels on the basis of driver's physical and mental health.

A variety of studies have been conducted in Occupational diseases (ODs) and this makes it difficult for researchers to identify new areas of study. Therefore, the present study was conducted by examining Web of Science data to identify hot topics and research topics on ODs. This is a scientometric study performed using CiteSpace and Gephi software for statistical analysis. The published article in Web of Sciences was searched using the keywords "Occupational disease * " OR "Occupational illness * " OR "Industrial disease * " OR "Industrial illness * ". Finally, the countries and institutions and their cooperation, the most important and main topics discussed, and the path of future progress in ODs was analyzed. Preliminary results of the study show that out of 5,947 articles. The results of important journals showed that the American Journal of Industrial Medicine with 233 articles (6.02%), Oxford Occupational Medicine, and International Archives of Occupational and Environmental Health with 86 (2.22%), and 83 (2.15%), respectively. The two producing countries are the United States and Germany, which published 628 and 419 articles, respectively. The results of hot topics showed occupational exposures, epidemiology, mental health, and respiratory diseases were the most important keywords used in these 45 years. It can be concluded that Germany, with its current development trend in the coming years, will surpass the United States based on the number of articles and gain the first rank. Also, future studies can be conducted on respiratory diseases as the most important ODs and health care work as the most important job during the past years., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Saberi, Rabiei, Zare, Jazari and Malakoutikhah.)

Background: Musculoskeletal disorders are responsible for significant problem for workers' health. The present study aimed to investigate the prevalence of musculoskeletal disorders among mining workers., Methods: This systematic review and meta-analysis study were designed in 2020 (from Jan to Mar). The researchers searched five international databases Medline/PubMed, ProQuest, Scopus, Embase and Web of Science. All analyzes were performed using STATA statistical software., Results: The search results were 447 articles and after screening stage finally 50 studies were included in review. The highest number of studies (26 studies) reported the prevalence of musculoskeletal disorders of upper back and 4 studies reported the prevalence of musculoskeletal disorders of the arms and ankles & feet. The results of meta-analysis based on prevalence in different organs showed that the highest prevalence of musculoskeletal disorders was in the upper back and the lowest in the knees with a prevalence of 50.39% (CI 95%: 31.23-54.73%) and 16.03% (CI 95%: 11.78-20.28%), respectively., Conclusion: The prevalence of musculoskeletal disorders among miners is relatively high.

Background: Unsafe behaviors are the cause of 80% of accidents. However, there has also been no worldwide review and meta-analysis of the prevalence of workers' unsafe behaviors. Therefore, the present study aimed to investigate and estimate the prevalence of unsafe behaviors among Iranian workers using a systematic review and meta-analysis study., Methods: This systematic review and meta-analysis were conducted from Nov to Dec 2018. The researchers searched Medline/PubMed, Scopus, Embase, Science Direct, and Google Scholar for international articles and four Iranian databases (Scientific Information Database, MagIran, IranMedex, and IranDoc) for Persian articles. The method of reporting this study was based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) checklist., Results: Overall, 235 articles from databases were imported to EndNote library. Final screening of the included studies produced a total of 38 studies. Based on the random-effect model, the prevalence of total unsafe behaviors, nonuse or inappropriate use of personal protective equipment, and inappropriate work posture was 40.37% (CI 95% = 35.8-44.9), 27.79% (CI 95% = 21.2-34.3), and 14.87% (CI 95% = 10.7-18.9). There was no statistically significant relationship between unsafe behaviors and mean age, mean of work experiences, and year of study., Conclusion: The prevalence of unsafe behaviors among Iranian workers was relatively high and the most common behaviors were non-use or inappropriate use of PPE; one of the most important causes for this behavior is lack of training, inappropriate working conditions, and lack of positive attitude towards safety. Therefore, further studied are required to investigate the causes of these unsafe behaviors., Competing Interests: Conflicts of interest The authors declare no potential conflict of interest with respect to the research, authorship, and/or publication of this article., (Copyright © 2021 Malakoutikhah et al.

Background: Musculoskeletal disorders (MSDs) are considered an important health concern, particularly in automotive assembly industries. Evaluation of the effects of all MSDs risk factors is difficult due to its multifactorial nature. In addition, the risk factors cannot be detected accurately when they are only based on individual opinions. Thus, in this study, fuzzy logic tool was used to evaluate the combined effects of all risk factors on MSDs. Methods: This cross sectional study was conducted on 100 male workers in an automotive industry. Job satisfaction, job stress, job fatigue, and body posture were evaluated by a self-reported questionnaire. Body posture was evaluated using Rapid Entire Body Assessment (REBA). Primary data analysis on extracting the input variables of MATLAB was performed by SPSS 22, with a significant level of 0.05. T test, one-way Anova, and Pearson correlation analysis were used to extract the input variables for the fuzzy logic model. The results obtained from the Nordic questionnaire was selected as the output of the fuzzy model. Fuzzy logic assessment was performed using MATLAB software version 7.0. Results: There were significant differences between WMSDs factors, including job fatigue, strain, working posture, and the REBA final score, and pain in all limbs of the body (p<0.05). A significant difference was also found between working posture with wrist score (p<0.05). The findings on defuzzification showed a strong correlation between real and modelling results. Conclusion: The results showed that many factors such as posture, fatigue, and strain affect MSDs. Based on the obtained results, all categories of risk factors, including personal, psychosocial, and occupational, should be considered to predict MSDs, which can be achieved by a modeling approach., (© 2019 Iran University of Medical Sciences.)

Background: Small and medium-sized enterprises (SMEs) include a large part of manufacturing jobs and play an important role in developing national economics and employment., Objectives: The present study aimed to investigate occupational health problems and safety conditions among SMEs in Shiraz, Iran., Methods: This cross-sectional study was carried out on 711 SMEs, including 371 small enterprises (fewer than 25 workers) and 340 medium enterprises (25-99 workers), in Shiraz, Iran. The participants were selected randomly among the workplaces under the coverage of social security insurance. The researcher-made questionnaire, which consisted of demographic characteristics, the frequency rate of occupational accidents, and exposure to workplace harmful agents, were distributed among participants., Findings: The results showed there were significantly more physical and chemical harmful agents in medium enterprises compared to small ones (P < 0.001). However, the frequency rate of accidents in small enterprises was significantly higher than in medium enterprises (P < 0.001). Also, there was no significant difference between the studied enterprises in ergonomic hazards, except for awkward posture, whose frequency rate was significantly higher in small enterprises (P < 0.05). Finally, among the reported symptoms, the prevalence of eye, skin, ear, and respiratory symptoms was significantly higher in medium enterprises compared to small enterprises (P < 0.05)., Conclusions: Occupational health and safety (OHS) regulations in medium enterprises have led to improved OHS conditions compared to small enterprises. Therefore, small enterprises should be included in OHS regulations., Competing Interests: The authors have no competing interests to declare., (© 2019 The Author(s).
