Safety analysis of a corn processing industry by energy trace and barrier analysis method: a case study

Background and aims   Each year many people die from accidents at work. Enormous costs of these accidents have forced specialists looking for ways to prevention of accidents. This study focuses on evaluation the safety of glucose production unit by energy trace and barrier analysis (ETBA) and present approaches to prevention of accidents.   Methods   Steps to perform ETBAmethod was completed in the field study. Data was collected by interview with workers and supervisors, document surveys and direct observations. 41 ETBA worksheets were completed for seven fold parts of production unit. Most unacceptable risks were   found in starch site.   Results   Findings showed that unwanted flow of potential energies create the most unacceptable risks in production unit. We concluded that the human factors would play main roll  in reduction of risks and control hazards. Also, administrative controls are suggested, especially  establishment of repairing and preventive maintenance system, organizing team for investigation  and record keeping of accidents, reporting and scientific analyzing of accidents and incidents  would reduce the total risk of industry.   Conclusion It will be useful to use the techniques that research human role in accidents associated with ETBA method

Assessment of reliability and validity of a new safety culture questionnaire

Background and aims   As a Development of Industrial process, human, environment, equipment, material and validity of system has been exposed to hazardous conditions. Regards of 32.3 percent of occupations in industries, this study focused on risk assessment of foundry unit by energy trace and barrier analysis (ETBA) method and presented approaches to control of accident.     Methods   the recent study is as a case study one to risk assessment in a foundry unit in Qazvin industrial city in1387. In this study risks were founded by ETBA method and evaluated by MILSTD- 882B. Data were collected by direct observations, interview with workers and supervisor and engineers, walking-talking through method, documents investigation of operational processors, preventive maintenances, equipment technical properties, accidental and medical documents. Finally ETBA worksheets completed.     Results   totally 154 risks has been found. 40 from total are been unacceptable risk, 68 unfavorable and also 46 acceptable but with remediation action. Casting workshop had risks more than other workshops (with 74 identified risks).Potential and heat energies were founded as most   hazardous energies, with respectively 51 and 38 risk cases.     Conclusion   This study recommended to be done actions for identification and control risk, such as: safety training, occupation training, preventive maintenance, contract safety, safety  communication and safety audit group.

The Study of Implement of HCS Program at Hazardous Chemicals Knowledge and Safety performance in Tehran refinery, s laboratory unit

Background and aims   The HCS standard includes listing of chemicals, labeling of chemical  containers, preparation of material safety data sheets, writing plan and employee training  programs. The aim of this study was to determine the influence of implemented program to enhance the knowledge and safety performance level of employees.   Methods  &nbsp;The knowledge level and unsafe act ratio were measured using both questionnaire  and behavior checklist (with safety sampling method) before and after enforcing this interface.   Results   In this study, the mean and standard deviation of the knowledge level of employees  related to chemical safety before enforcing the interface was 46% and 14%. However, after  enforcing the interface, mean and standard deviation was 88% and 12%. The paired-t-test result   in this parameter was significant (p-value <0.0001). The mean and standard deviation of  knowledge level of employees related to warning labels before to enforcing the interface was 29%  and 22%. After enforcing the interface, mean and standard deviation was 80% and 16%. The paired-t-test result in this parameter was significant (p-value <0.0001). The mean and standard  deviation of the knowledge level of employees related to hazard communication methods before enforcing the interface was 25% and 11%. After enforcing the interface, mean and standard deviation was 79% and 16%. The paired-t-test result in this parameter was significant (p-value   <0.001).   Conclusion   The obtained result revealed that enhancement of the knowledge related to chemical safety, hazard communication methods and warning labels was significant. Statistical paired-t-test and control chart methods was used to comparison between unsafe act ratio before  and after enforcing the interface. The mean and standard deviation of unsafe act ratio before implementation of HCS program was 23.6% and 5.49%. However, mean and standard deviation of unsafe act ratio after implementation of HCS program was 18.1% and 6.18%. Therefore, after  implementation of HCS program unsafe act ratio decreased (5.45%) significantly (p-value   <0.0001). This result implies that chemical safety performance of employees was increased

Mental Health in High-Tech System

Stress and mental health at the place of work have received great attention by researchers. In spite of technology improvement in high-tech systems, the operators face new problems, which can affect mental health. There is hardly any published research about stress or mental health in such workplaces in developing countries. This paper presents the application of the self-rating scale General Health Questionnaire (GHQ-28) to study mental health of 160 controllers working in a part of Air Traffic Control (ATC) as a high-tech system in Iran. Logistic regression analysis showed that demographic variables did not exhibit a statistically significant effect on scores of the test. In order to compare mental health of these operators with general population, an exposure / non-exposure study was designed. Three age groups (less than 29 years, 30 through 39 y, and more than 40 y) were compared in exposed and non-exposed groups. The results of Fisher’s exact test showed that mental distress symptoms were significantly higher in the exposed group. There were significant job effects on somatization, anxiety and depression as well as on the total score of GHQ-28 for the two first age groups (P&lt;.05). No significant effects of the job were found on social dysfunction symptoms in any age groups. The risk ratio of expressing depression and anxiety symptoms were more than three times greater in these operators than general population
