Abstract

Background: What-If is a systemic approach tool based on teamwork that enables to identify and assess systematic deviations in the work process, humanitarian performances and equipment defects by brainstorming ways. Because Yazd province has multiple ceramic and tile factories, this study was done to evaluate effectiveness of control measures to reduce the risk level of work-related hazards in Ceramic Industry Methods: This study was before-after (quasi-experimental) study. Among the Ceramic factories in Yazd province, one factory was selected as a sample, after an initial assessment by expert team, corrective strategies were implemented, and Risk Assessment Code 2 (RAC2) Obtained. Data was analysis by SPSS 16. Results: 107 dangerous were identified in all units, the lowest and highest risks identified was related to the guarding unit and the maintenance unit respectively. Number of acceptable risk before and after the intervention, the lowest acceptable risk and unacceptable risk was reached from 7 to 90, 85 to 17 and 15 to 0 respectively. Conclusions: The results showed that the combined engineering- management actions had been affected more than each of these measures alone in reduction the risk code number. By using this method, the risk at hazardous environments can be reduced or controlled and it was an ideal risk management tool for all industries alike

Abstract

Background: By considering the development of power plants in the country and identifying potential hazards in the mentioned work process, this study intends to change analyzes before and after the implementation of integrated management systems to control the consequences of hazards by this systematic methods. Materials and Methods: This study is a descriptive - analytical in type of before and after that during the years 1383 to 1390 in Yazd combined cycle power plant is accomplished. Variables are hour of work, days of lost work, the coefficient of accident frequency rate (AFR), coefficient of accident severity rate (ASR), the coefficient of accident frequency severity rate (FSI), the coefficient of T Safe (safe t score) and the coefficient of incident rate (IR) and frequency rate (FR). Results: Among different jobs, the highest number of accidents was related to workers and the lowest number of incidents was related to engineers and experts. The highest rate indicators of the frequency, intensity, intensity - frequency and frequency rate and incident rate coefficients related to the year 1383 (the year before the implementation of integrated management systems) and the highest accident severity index was related to year 1387. Meanwhile the lowest Value of all indicators belongs to year 1390. According to the safe T coefficient, until 1388, changes have been Significant and the situation has improved and significant in the years 1390-1389 (safe t score <-3). Conclusions: Results have showed that the implementation of safety programs has a positive impact on reduction of accident indicators and on various situation is used by coefficients that change trend will show better than control chart.

Abstract

Background and Aim: In recent decades, the issue of stress and its negative consequences such as violence in the workplace, increased accidents at work, Absenteeism and burnout, have deleterious effects on the efficiency and economy. The aim of this study was to determine the occupational stress of pelletizing industry workers and its determinants.
Methods: This study was descriptive - analytical and cross sectional. Among of pelletizing plant workers selected 120 subjects (randomly) and according to the shift, they are divided into two groups of Shift and non-shift work and for the estimation of stress, 120 occupational questionnaires with 92% reliability was completed and Statistical data was analyzed by the SPSS software.
Results: 88% of employees had severe stress. Severe stress was observed in shift work, low age and experience (in both shift and non-shift), respectively, 90%, 96.2% and 94.7%. 92.6% of smokers also had severe stress. Between job stress and levels of education, and marital status and sleep problems were not significantly association (p>0/05).
 Conclusions: According to the result of presented study, shift work, smoking, low age and experience were the causes and triggers of stress. Therefore it is suggested, takes into account the selection and periodic examinations of workers with these characteristics for stressful jobs and so identify sources of stress for reducing causing factors as systematically and prioritize be attempted.

Abstract

Introduction: According to the increasing growth of industries and technologies and consequently increasing accidents and occupational diseases, this study aimed to by analyzing the main causes of accidents in Yazd Combined Cycle Power Plant and finally prepared the situation to present suitable control measures.

Methods: This study is a descriptive–analytical, which is analyzed the trend of occupational accidents. In this study, information collected through check lists and interviews with accident victims and based on the data extracted, the accident indicators were calculated. Then, the data were analyzed using SPSS software.

 Results: During an 8-year- period, out of 1189 workers, 287 cases of occupational accident have been registered. Results indicated that there was a meaningful relationship between the age, job experience and marital status. The most types of accidents and their causes were related to the trauma and unsafe acts, respectively. The most events had occurred in winter, at the beginning of the day shift in the maintenance unit. Accident indicators decreased specially accident frequency rate (AFR). In this study, maximum and minimum value of frequent-severity index was 1.74 in 1383 and 0.56 in 1390, respectively. In addition the results showed that, education level on accident frequency rate and income monthly had a protective effect on accident frequency rate and severity- frequency rate (FSI).

Conclusion: Nowadays, to prioritize hazards and corrective actions, it was used the results of techniques and risk assessments. The results related to accidents can be used at comprehensive database as well as they wereutilized for qualifying the risk the risk assessments.

Abstract

Introduction: The latest way to control the use of hearing protection devices is sound. The amount of time spent on the phone by workers is one of the most important parameters in hearing conservation programs. The aim of the study is to evaluate the effectiveness of training scenario in theoretical and practical ways to increase using the hearing protection devices for workers.

Materials and methods: In this experimental study, according to the results of the initial stage of the questionnaire, in the experimental group (n= 50) for 5 sessions (practical theory), each shown for 30 to 45 minutes, and workers in the control group (n= 50) in this study have not received any training, and time spent on the phone before and 3 months after intervention in both groups were recorded and compared.

Results: The results show that before intervention only 1 worker (2%) used the device for all time and after intervention 33 workers (66%), which reflect positive effect of training intervention on using the devices. All the conditions were the same for two groups the control group did not reflect significant changes due to lack of training program.

Conclusion: According to the findings, it can be said that the training scenario has been successful in increasing the use of hearing protection devices and also can be used in other health interventions.

Abstract

Introduction: Occupational hearing loss due to noise is completely preventable and using the hearing protection device is one of control proceedings by the workers expose the impermissible noise. Therefore, this study aimed to determine the effective factors on occupational hearing loss and also the effective factors on using hearing protective devices by the workers exposed to excessive noise.

Method: In this cross-sectional analytical study, 100 workers exposed to excessive noise were selected through sampling method. Data collection tools were a demographic information questionnaire and BASNEF model constructs, which its validity and reliability were confirmed. Audiometry was performed and recorded for each employee. Data were analyzed by SPSS software, version 19.

Results: The findings showed that the age and occupational history had a meaningful relationship to hearing threshold shift (p-value<0.05). There is no meaningful relation between martial statue and education level (p-value>0.05). Also, there was a meaningful relationship between education and duration of using the hearing protection device (p-value<0.05). There was no significat relationship between duration of using the hearing protection device with marital status, education level, job tenure and age (p-value>0.05).

Conclusion: The results show that there is a relation between the training of BASNEF model and duration of using the hearing protection device; so this training should be considered in hearing protective programs.

Abstract

Introduction: Today, organizations need an integrated management system (IMS) to achieve global standards regarding the environment and employees. And one of the important goals of an integrated management system is to eliminate or reduce disasters to an acceptable level of organization. Therefore, in this study, we try to measure the efficiency of deployment of this system on safety performance monitoring indicators.
Materials and Methods: This study is a descriptive-analytical study conducted during 2009 and 2010 (years before implementation of integrated management system) and years 2011 to 2014 (years when integrated management system was implemented in all units of one of the tile factories of Yazd city. In this study, all the information related to the events in this industry was collected. Then the variables of accident repetition coefficient (AFR), accident severity factor (ASR), repetition-intensity factor (FSI) and Safe-T-Score were calculated and analyzed.
Results: The incidence of recurrence coefficient, accident severity coefficient and recurrence-severity coefficient decreased from 2009 to 2014. The safe T coefficient also shows that in 90 (the beginning of the implementation of integrated management system) and 91 the number of accidents has significantly decreased compared to previous years.
Conclusion: The results of this study show that the implementation of integrated management system can increase safety indices and thereby increase the level of factory safety.
