Introduction: Industrial accident is one of the most minatory elements for worker’s health, productivity and organizational performance. Unsafe behavior is the main reason associated with occurrence of accidents. The main goal of this study was application of participatory techniques to achieve control measures of these behaviors.

.

Material and Method: Using safety behavior sampling technique in this study, behaviors of staffs were evaluated and then the most risky behaviors were determined by paired comparison method. By application of participatory approach of dotmocracy in six steps, controlling ideas were derived by participation of operators, supervisors, engineers, HSE team and managers.

.

Result: 48.8% of the behaviors were unsafe. Misuse or notusing of the personal protective equipments with 63.4% was the most frequent unsafe behavior. Awkward postures, aggregation or passing under suspended loads were also followed by the unsafe behaviors. By application of participatory approach of dotmocracy, several applicable ideas in personal protective equipment, education, reinforcementand punishment, aggregation or passing under suspended loads and other ideas were achieved.

.

Conclusion: Dotmocracy participatory technique is an effective way to achieve various practical solutions in control of worker’s unsafe behaviors.
