Introduction: Occupational exposure with polluted sharp equipment usually occurs during procedures such as transfusion of blood and blood products, blood sampling, disposal of needles, and collection of polluted sharp materials. Considering the fact that students have less work experience and lower practical skills, they are more vulnerable to work-related infections. The present study was conducted to determine and compare the awareness of nursing, midwifery, and surgical technology students about occupational exposure management.
Methods: This descriptive-analytical cross-sectional study was conducted on 221 students of nursing, midwifery, and surgical technology selected using the stratified random sampling in 2016. Data gathering tool was a researcher-made questionnaire including the students' demographic characteristics and awareness about occupational exposure management. Data were analyzed by SPSS₁₈ using descriptive and analytical statistical tests.
Results: Our findings showed that the mean scores of awareness about occupational exposure management were not significantly different among the nursing, midwifery, and surgical technology students (p value = 0.435). We observed that the students' age and educational level were significantly correlated with their scores of awareness about occupational exposure management (p value < 0.001).
Conclusions: Results of the present study indicated poor awareness of the students about in-time management of occupational exposure. Measures such as educational workshops on preventive aspects in occupational exposure, observance of safety principles and comprehensive standards for accurate measurement of viral markers should be taken. Individual health profiles should be designed for each student to improve the occupational exposure management.

Introduction: In most process units of refinery industries, staffs are exposed to various chemical agents. The purpose of this study was to identify the highest level of occupational exposure to Benzene, Toluene, Ethyl Benzene, Xylene compounds (BTEX)and to assess the risk caused by them in staffs of an Oil Company.
Methods: Initially, the staffs' tasks, work processes, and harmful factors in the working environment were determined based on the occupational groups. Then, 10 site staffs, who were in the same shift work were selected. According to NIOSH method number 1501, air sampling and BTEX analysis were performed. To analyze the results, IHSTAT software of American industrial hygiene association was applied. Finally, the risk assessment was done in accordance with the method number 84101042 of Oil Ministry.
Results: The statistical analysis of the measures indicated that exposure to toluene, ethylene benzene, and xylene was at the permitted level, but high exposure to benzene was not determined. The risk assessment showed that Benzene had a medium risk rating. Moreover, Toluene, Ethyl Benzene, and xylene had low risk rating
Conclusion: According to the severe consequences of benzene exposure, corrective and preventive measures should be taken to remove or decrease the exposure rate.
