Among all deathful and destructive factors, the work related accidents
   are of special importance. The principles of accident prevention have been
   changed after the mid 20th century based on refusing and decreasing
   the human unsafe acts. The most important step in accident prevention is
   recognition  of accident occurrence reasons, so, it is necessary to evaluate
   the labors’ unsafe acts that are the main causes of accident .

          In this study, the workers’ unsafe acts in Godazan factory were
   evaluated by safety behavior sampling method, observation and interview
   in 2000.  After description of unsafe acts, the sample size was 573 cases
   based on results of pilot study and sampling accuracy to 5% and
   confidence level to 95%. Using questionnaires , variables related to the
   workers were collected.

          The results showed that 59.2% of workers acts are unsafe. The most
   important unsafe acts are not using personal protective equipment with 50%
   out of total unsafe acts. The results showed a significant difference between
   unsafe acts and age, number of family members(p<0.01) ,education and
   former accident(p<0.05).
