Background: In order to control occupational accidents, it is essential to find out unsafe behaviors and their rate among workers. This study was aimed to determine unsafe behaviors rate and offer some control measures. Methods and

Materials: In this descriptive-analytical study, safety sampling technique, interview and document review methods were adopted. In a pilot study, the number of observations and samples were determined 3145 and 185, respectively. Finally, in order to analyze the data, Chi-squared test and regression were used. Findings: The results showed that 25.08% of the workers behaviors were unsafe. It was found that there is a significant correlation between unsafe actions and education level (P> 0.05) while the correlation between unsafe action and age, work experience, married status, job and time of observations was not significant (P< 0.05). Furthermore, the highest unsafe actions were observed in testing man and workers above 51 years old and above 21 years of work experience. Application/Improvements: Although the rate of unsafe behaviors in study group was relatively low compared with unsafe acts, the improper use of personal protection equipment was the most dominant problem. In order to reduce these behaviors, training programs, daily surveillance and safety culture improvement among workers and authorities are strongly suggested.
