At the second stage, after analysis of collected data, the frequency of each unsafe behavior and their proportion in the whole unsafe behaviors was obtained and then their probable relationships with some demographic features were investigated. Safety behaviors were calculated before and after (2 & 4 months) installation of standard safety signs (ANSI).

The most frequent ones were the abuse or lack of the use of personal protective equipments, inappropriate postures and incorrect use of manual tools. However, after 2 and 4 months from intervention, unsafe behaviors rate reduced to 33.2 and 38.7%, respectively. Conclusion: The use of safety signs has significant impact on reducing unsafe behaviors in staffs; however, its effectiveness is reduced over the time.
