Background: The rise of COVID-19 in the 21st century has posed challenges for national and international communities. Meanwhile, people who work in high-risk jobs in terms of biological exposure, such as banks, are more likely to be exposed to coronavirus. This study aimed to investigate the risk of probability and clinical severity of COVID-19 infection among employees of one of the bank branches in Shiraz, Iran.Methods: In this study, the risk of infection to Covid-19 among the desired bank branch employees was assessed using the Covid-age index. The related information was gathered through observation and face-to-face interviews using workplace risk assessment for exposure to SARS-COV-2 virus guidelines. Moreover, the International Labor Organization risk assessment standard was used to quantify the individuals’ risks.Results: The average COVID-19 risk score among studied employees was 4.6, categorized as low. Moreover, the employees’ mean age and Covid-age index were 44.7±3.65 and 47.6±4.52, respectively. The severity of the clinical picture was evaluated as mild to moderate (levels 1 and 2). Moreover, the risk of disease was considered 2 for all employees, considering the work environment.Conclusion: The results of this study showed that the Covid-age index could effectively evaluate and quantify the risk of exposure to COVID-19. Bank personnel is exposed to the biological risk of COVID-19. People with the underlying disease are at higher risk of COVID-19 consequences.

Background: Personality traits, due to having a relative stability, are important factors for predicting employees’ safety behavior. Consideration of Future Safety Consequence (CFSC) is a personality trait that was recently introduced to predict the safety behaviors. The purpose of this study was to translate and assess the psychometric properties of the Persian version of the CFSC scale.Methods: In the first stage of this cross-sectional study, the instrument was prepared by the forward-backward forward translation technique and evaluated by 487 employees of a gas refinery. The validity of the scale was evaluated through face, concurrent, validity, and construct validity. The safety performance questionnaire was used to examine the concurrent validity. The reliability of the questionnaire was evaluated using internal consistency (Cronbach’s alpha coefficient) and test-retest.Results: Content validity index was 0.885. The results of exploratory and confirmatory factor analysis indicated that the CFSC scale had a single factor. Also, Pearson correlation showed a positive correlation between the safety performance and the Persian version of CFSC (R=0.401). Test-retest reliability and internal consistency were calculated as 0.86 and 0.82, respectively.Conclusion: It is concluded that the psychometric properties of the Persian version of CFSC scale are desirable and can be used in future studies

Background: Teachers are prone to Voice Disorder (VD). The present study aims to investigate the onset of VD symptoms and their effects on the job performance of the elementary school teachers. Methods: This cross-sectional, descriptive-analytical study was conducted on 121 male and female elementary school teachers in Mobarakeh County during the academic year 2018-2019. Data were collected using a researcher-made questionnaire. In doing so, the researchers talked to 10 people composed of qualified experts in occupational health, ergonomics, and health education and a number of teachers about how to design the questions as well as the answer scale for each section. Results: In the present study, the prevalence of VD was higher among female teachers (41%) compared to male ones (20%). That is to say, the prevalence of the VD symptoms in female teachers was more than twice that of the male teachers. The study results demonstrated a significant relationship between having a silent resting place and coughing (p=0.028). Accordingly, the prevalence of the symptoms of cough was significantly higher in the teachers who did not have a silent resting place in comparison to those who benefitted from a quiet resting place. Conclusion: Thus, it is recommended that safety, occupational health, and ergonomic programs should be designed for teachers at the Ministry of Education in collaboration with concerned specialists. Periodic examinations, identification of teachers with disorders, culturalization, and education are among the themes of these programs.

Background: The classroom is an important part of the educational environment, which should meet the standard requirements including safety and adequate spaces regarding the number of learners, color, lighting, noise, proper equipment, and air conditioning. This study aimed to investigate the safety level of classrooms in Shiraz University of Medical Sciences. Methods: This cross-sectional study was conducted in Shiraz University of Medical Sciences (SUMS) classrooms (n = 63), in the south-west of Iran. Data regarding the safety measures were collected using an audit checklist. Finally, an index called Classroom Safety Requirement Index (CSRI) was introduced in order to calculate percentage of safety measures in the classrooms. Results: The results revealed that the ‘environmental condition’ dimension of the CSRI was in a good level. The ‘building’, ‘equipment’ and ‘electrical’ dimensions were in the medium level, and the ‘fire safety and emergency’ dimension was placed in the poor level. 38.70% of the classes (24 classes) were in the Standard Occupant Load (SOL or degree of overcrowding) and others (61.30% of classrooms) were overcrowded (unacceptable occupant load). Conclusion: The examined classrooms were very poor regarding the ‘fire safety’ and ‘emergency exit’, which requires proper and appropriate measures to improve safety in these areas.

Background: Safety is a part of organizational climate and reflects the workers’ current perception toward safety issues in an organization. The aim of this study was to survey the level of safety climate and its associated factors in various enterprises. Methods: Data were collected using Persian version of Nordic safety climate questionnaires (NOSACQ) which was distributed among 661 employees of different industries in Qazvin Province. This questionnaire consists of six dimensions. The data were analyzed using IBM-SPSS Statistics 2010 and Microsoft office excel. We used the Mann-Whitney Test, Kruskal-Wallis Test, Spearman's Rho-Kendall's Tau-B, Tukey (POST-HOC) and - Way ANOVA tests to find the association between the variables and safety climate scores. Results: The mean age of the subjects was 29.97(± 5.53) years; 66% of them were married, 91% were males, 31% had a college degree, 47% were rotating- shift workers, and 80% were employed through contracts. Their average work experience was 17.27(±15.4) years. The values of Cronbach’s Alpha were acceptable in the study groups; the highest and lowest levels of safety climate were observed in ceramic and mine industries, respectively. Conclusion: There were some relationships between the safety climate and variables of level of education, work shift, presence of occupational and health department (OH&S) as well as safety management system, age and work shift.

Background: Individual factors play an important role in the safety performance of small and medium-sized enterprises that might have physical, mental or psychological nature. Some of these factors are related to the subjects’ personality and unchangeable; however, others are related to motivation and attitude, which could be improved through training. This study aimed to assess the safety attitude and its effective factors among workers in micro- and small-scale enterprises (MSSEs) in Shiraz in 2015.Methods: This cross-sectional study was conducted on 349 workers in MSSEs. Safety Attitude Questionnaire (SAQ) was filled out by self-report method which consisted of questions including general information, cognitive, affective and conative dimensions. Then, SPSS software version 22 was used to assess the significant difference between the variables (p-value <0.05).Results: The mean score of safety attitude was (103.05±8.73 out of 125). The minimum and maximum safety attitude scores were related to affective (16.13±3 out of 20) and cognitive (46.7±4.12 out of 55) dimensions, respectively. Also, there was a significant difference between the educational level and safety attitude. Workers with higher education had higher safety attitude scores.Conclusions: The results showed that most of the workers had safety attitude but they were not desirable in affective and conative domains. Therefore, it is required to enhance the affective domain through training the workers, enhancing their participation, paying attention to their views on occupational safety and health issues and promote the conative one through the supervision of legal authorities

Background: Most workers are exposed to a variety of hazards in their workplace. Devising a comprehensive checklist and developing an index for Occupational Safety and Health (OSH) assessment could be useful. This study was conducted in a heavy automotive company with the aim of developing and validating an OSH assessment index.Methods and Materials: We used the experiences and comments of OSH experts to devise a checklist for OSH assessment. Weighting various harmful factors was done using Analytical Hierarchy Process (AHP) technique. Intra-class Correlation Coefficient (ICC) was applied to measure the reliability of the checklist (SPSS version 20). In the studied industry, 150 workstations were assessed using the developed comprehensive checklist. In order to validate the total index, we assessed its correlation with 4 groups of occupational statistics (i.e. accident frequency, severity rates, lost working time rate, and occupational disease incidence rate). A p value of < 0.05 was considered significant.Results: Among 7 sub-indices, sub-indexes of occupational health and the workplace order (w=0.21) and housekeeping (w=0.04) had the highest and the lowest AHP weights, respectively. The mean of ICC was found to be 0.978. The total index (OSHITotal) and the Accident Severity Rate (ASR) had a strong inverse significant correlation (r = -0.774, P=0.002).Conclusion: The developed index covered important occupational hazards. The inter-evaluator reliability for this index was high.
