Critical success factors for sustainable health and safety practices in Malaysia’s construction industry

Objectives. This study investigated the critical success factors (CSFs) necessary to promote sustainable health and safety practices in Malaysia's construction industry. Methods. A closed-ended questionnaire was developed based on a comprehensive literature review and validated by experts. The questionnaire was distributed to construction professionals across Malaysia, yielding 158 valid responses. Data were analyzed using fuzzy synthetic evaluation (FSE) to rank the importance of each factor. Results. The findings highlight three core dimensions essential to sustainable health and safety: environmental, economic and social sustainability. Key elements include the use of eco-friendly materials, effective waste management, financial investment in safety systems, stakeholder involvement, inclusive workforce practices and mental health support. Practices such as reducing waste, conserving water and energy, and minimizing pollution were frequently associated with sustainable outcomes. Conclusion. Together, these dimensions offer a robust framework for improving health and safety in the construction sector. Integrating environmental, economic and social strategies enhances worker well-being, lowers operational risks and supports long-term industry resilience. The study concludes that sustainable safety practices not only safeguard lives but also deliver economic and operational benefits for construction firms. © 2025 Central Institute for Labour Protection–National Research Institute (CIOP-PIB).
