measures practice towards occupational hazards among critical care nurses ' working long
shifts. Research Design: A quasi-experimental, repeated measures design with a one-group < br />Pretest/posttest was selected to test participants at 3 pre-specified time points (initial,
immediately after training, and at 3months later after training). Setting: The study was

and safety measures practice towards occupational hazards score was found in the post
educational intervention phases both immediate post intervention and follow up after three
months later in comparison to the pre- educational intervention. Conclusion: The
intervention tested in this study shows promise of being an effective approach to promot
knowledge and safety measures practice towards occupational hazards among critical care
nurses ' working long shifts. Recommendation: Mandatory regular educational intervention
