Investigating the Impact of Safety Responsibility and Safety Attitude on Safety Voice among Graduate Students in Chemical Research Laboratories

This study examines the impact of safety responsibility and safety attitude on safety voice among graduate students concerning laboratory safety. The results show that the safety responsibility and safety attitude of graduate students positively correlate with their safety voice. In addition, the moderating role of mentors’ safety leadership is significant. High safety leadership strengthens the positive link between safety responsibility/attitude and safety voice, whereas low safety leadership reverses it, suppressing voice despite increased responsibility/attitude. The results provide data support and practical reference for the safety management of chemical research laboratories.
