The attitude of hospital workers toward safety culture in working domain has a direct effect on safe quality of care services to patients. Therefore, the purpose of this survey was studying the safety attitudes of the nurses of CCU in the educational and non-educational hospitals of Ahvaz and comparing them to each other.The cross-sectional study was performed for 75 volunteer nurses of CCU. The data was collected through a modified Safety Attitude Questionnaire (SAQ) relating to the CCU wards. Reliability and validity of the questionnaire obtained from other studies. The data on six safety dimensions include teamwork climate, job satisfaction perception of management, safety climate, working condition, and stress recognition were scaled and scored for positive and negative questions separately using a 5-point Likert scale. Statistical analyses of the means were conducted using SPSS 16 Anova and pearson correlation at a significance level of P< 0.05.the results showed that the scores average of safety attitude in the 6 parts, i.e., teamwork climate, job satisfaction, perception of management, safety climate, working condition, and stress recognition was 68.37, 55.26, 52.11, 48.46, 57.04, and 57.09 for the nurses of the educational hospitals, and 75.41, 65.14, 59.59, 54.32,57.63, and 68.73, for the nurses of the non-educational hospitals, respectively. The results also showed the significant difference in teamwork climate between the two kinds of hospitals (sig=0.026). In addition, an interstitial difference was recognized in the management understanding of the two kinds of hospitals (sig=0.059). In recognition of stress, difference between the two types of hospitals was also completely significant (sig= 0.0001). Managing and trying to increase mutual understanding, and also paying attention and planning to improve effective factors of nurse's job satisfaction, especially for the female nurses in educational hospitals, can be very effective in their safety attitude and safety culture improvement in working climate.

From the 70s onwards, safety engineering made significant progress in developing techniques and regulations relating to the fire. The first, this methods was considered after happening accidents to prevent similar accidents. But with the advancement of technology, the prediction and prevention of fire in complex industries such as power plant finds Important. This study is done to determine the risk of fire in the control room of a power plant and proposed effective strategies to fire prevention. In this study, based on fire risk assessment methods for engineers, computational package was prepared by EXCEL software. Next to the building and contents, residents and activities in the plant control room, risk assessment calculations were carried out separately. At the end based of FRAME pattern, proposed appropriate control measures. The results showed that the risk of fire for building and contents is 1.02, residents 20.6 and activity is 0.5. According to the acceptable level of risk in the method, only the risk of fire in activities within the acceptable range. The results showed that in case of fire, the expected damage to buildings is 10-20 percent. The fire risk for residents is required to take preventive measures to reduce the level of risk. The results showed that the FRAME method, in addition to risk assessment can determine the strengths and weaknesses of existing systems and will provide appropriate control measures to prevent fires in buildings built.
