Basical metals industry has developed in recent years. Accident control to protect the human force is a major constant development element and foundry as a mother industry has been shortly considered. Regard to the importance of topic for risk assessment and identification numerous methods such energy trace and barrier analysis of comparative controlling systems developed for risk assessments in muscle unit. This study is a descriptive research in Balin Tak Company. In this research, safety assessment is done by Energy Trace and Barrier Analysis and risks assessment has been done qualitatively. To do these, risk matrix represented in (ET and BA) was utilized to qualitative categorization of intensity and risk possibility. In standard MIL-STD-882E related to this research, sixteen risks were identified, four unacceptable risks, six unfavorable risks and six acceptable risks with review. This research is implementation of appropriate monitoring efforts of 1A. Meantime, fall is with risk number, Housekeeping training by surveillance and audit settlement, engineering efforts, regular safety schedule for staff, punitive and appreciating plans to consider safety rules to reduce risks.

Automobile manufacturing is one of the most important industries in Iran which their workers are involved with the variant physical activities and accidents. Regard to importance of this industry in viewpoints of national economics and also workers’ safety and compatibility to situations, this study has been conducted to management of identify and assess risk factors process among operational workers of an automobile manufacturer company in Iran. This cross sectional study has been done in production line of an automobile producer in Iran using "Hazard/Caution Zone" method, along with Hierarchal Task Analysis (HTA) and time study after validity study of tools, in 2014. Data analysis illustrated that three factors (1) Using the same motion with little or no variation every few seconds - no other risk factors in %80 of jobs (2) High Hand Force- repetitive motion in %73.33 of jobs (3) Working with the neck bent more than 45° in %46.67 of jobs were in caution zone. Extra studies show each of two first factors is in hazard zone in %6.67 of jobs. Combined data show most of studied jobs have more than one factor at unacceptable level. Environmental and occupational risk factors are low regard to amount but considering %93.33 of studied jobs contains one risk factor at least so, it is likely to increase in problems. Therefore, they need to be monitored continuously. Also, corrective actions should be done as soon to control musculoskeletal disorders and accidents prevalence.

Workload is one of the main factors result in accidents. One of the important sciences that can help managers to promote workers’ health and safety is ergonomics, especially cognitive ergonomics. From this science’s point of view mismatch between workload and human’s capability is the main factor of injuries. This article presents result of workload and its dimensions among administrative staffs of a medical sciences university in Iran, in 2014. This cross sectional study conducted by survey all the administrative staffs (n=223). Workload is survived by NASA-TLX questionnaire and demographic factors gathered using a questionnaire developed by research team. Data has been analyzed by t–test, ANOVA and Pearson correlation using SPSS V20. Data analysis results declare workload with 76.15 as average scale. Its reliability was analyzed by cronbach's alpha and was 0.83. In addition, physical workload has statistical significant difference among educational groups (p<0.05). Totally, workload was in high level. Administrative controls and actions should be used to improve conditions and also workload dimensions specially two dimensions have highest portions (Performance and Effort) needed to be modified to improve safety.

safety culture is considered as the core of an organization's safety management system. Safety culture is an organization's ability to achieve higher standards of safety. The aim of this study was to assess safety culture and its influencing factors in the Bafg quarry mine company. This cross-sectional study was conducted among 223 workers in the Bafg quarry mine company. In order to determine the level of safety culture in the quarry, safety culture standard questionnaire was used that included 80 questions. The Results of study showed The mean of the subject’s age, work experience and score of safety culture were 34.14±7.8, 12.17±6.4 years and 256.6±33.4, respectively. A total of 60 individuals had a history accident. The most common cause of the accidents was indiscretions (56.7%). There was a statistically significant correlation between Safety culture and accident history and work experience (P<0.05). The percentage of a positive safety culture of workers with accident history was more than the percentage of those without an experience of accident. There was not a statistically significant correlation between safety culture and age, education, and marital status. It seems that safety culture is influenced by the accident history in the Quarry and there was a significant relationship with the history of accident. So, in order to improving the safety culture in the workers should be invested on safety training, use of experienced workers and analysis of events.

In today's world, one of the most important components of a working environment to achieve continual improvement in productivity is safety. A safety assessment technique by Frank Morgan is a risk analysis to assess and control the risks associated with them. In this way, the relative risk of total capital at risk and the overall risk of the plant is estimated. Finally, units are ranked based on overall risk. This cross-sectional study conducted in three workshops: extruding, printing templates, and dikes in a plastics manufacturing company. In this method the Check list of existing risk and control programs for each specified unit and by calculating the total capital at risk and overall risk compared to the final took place. According to a survey carried out in three different workshops of the factory obtained the following The risk, control scores, indicators of risk, relative risk, index risk, the overall risk of extrusion, printing templates, Dyke of monetary value 746319306.7, 394317296.8 and 10132582.65 rials respectively. The (77, 166, 79), (53, 61, 73),(-24, -105, -6), (-18, -99, 0), (15.34, 84.61, 0), (1848634280, 5868198747, 0) controls used in the extrusion unit 1% and a stencil printing unit 28% And 6% less per unit of risk in the workshop's Dyke. One of the most effective methods of prevention and control work-related accidents in the workplace is risk management. Therefore, the working environment needs to be assessed to ensure that any risks are identified. Forecasts and take necessary action to be taken is by a risk management program.
