The effects of different feedback mechanisms on safety engagement were examined in an industrial manufacturing setting with twenty employees. During a 30-day period, participants who received feedback showed a significant increase in safety engagement participation when compared to a five-month baseline period of no feedback. There was no significant difference in safety engagement participation between employees who received verbal feedback versus those who received written feedback. Furthermore, survey responses indicated that feedback improved employee attitudes toward the plant's safety program. Together, these findings suggest that feedback systems can be used to effectively improve industrial safety programs.
