| Summary: | Introduction: This cross-sectional study investigates the relationship between safety culture and stress-related disorders (SRDs) among chemical laboratory workers in Sri Lanka's academic, industry, and government sectors. Understanding the impact of safety culture on mental health is essential for developing effective interventions.
Methods: A total of 267 laboratory workers participated by completing the Laboratory Safety Culture Survey and the General Health Questionnaire (GHQ-12). The survey assessed key safety culture components, including attitudes, perceptions, laboratory practices, and safety opinions. Pearson correlation and multiple linear regression analyses were used to explore the relationships between these factors and mental health outcomes.
Results: SRDs were prevalent in 36.3% of participants, with many exceeding the GHQ threshold for mental health concerns. Sociodemographic factors, including education, job role, and chemical handling experience, significantly influenced mental health outcomes. Strong negative correlations were found between SRDs and safety culture subscales, specifically attitudes and perceptions, and safety opinions. Enhanced perceptions of safety culture and positive safety opinions were linked to potential reductions in SRDs by 32.4% and 52.1%, respectively. Longer chemical handling durations emerged as a significant predictor of SRDs. Multiple regression confirmed that a positive safety culture reduces SRD risk, while prolonged chemical exposure increases vulnerability. Industry workers reported higher SRD levels than academic and government sectors.
Conclusion: Enhancing safety culture, improving mental health support, and balancing safety with productivity are crucial for reducing SRDs and ensuring the well-being of chemical laboratory workers across sectors in Sri Lanka.
