Evaluating the effectiveness of the application of ISO 45001: 2018 Occupational Health and Safety Management System for improving the health and safety performance of the coconut-based manufacturing industry of Sri Lanka

Abstract

ISO 45001:2018 is widely recognized as an effective framework for occupational health and safety (OHS) management (Refer Chapter 2.8.2), yet its specific impact on health and safety performance within Sri Lanka’s coconut-based food manufacturing industry remains under-researched. Existing studies have primarily examined general manufacturing sectors, often lacking comparative analysis of safety performance between certified and non-certified entities within specialized industry contexts (Refer Chapter 2.6). This gap indicates a need for a targeted investigation into the benefits and challenges associated with ISO 45001:2018 certification in this niche sector. This study aimed to assess the effectiveness of ISO 45001:2018 in enhancing OHS performance in Sri Lanka's coconut-based food manufacturing industry. Certified and non-certified industries were compared to evaluate their influence on key OHS performance indicators. Data were collected from 37 respondents representing various management levels across large-scale industries located in the Gampaha, Kurunegala, and Puttalam districts. Responses were analyzed using a five-point Likert Scale (1-5) and SPSS V23.0 software. Findings demonstrate that ISO 45001:2018 certification significantly improves OHS performance, evident through reductions in workplace accidents, enhanced regulatory compliance, and increased employee participation in safety initiatives. Comparative analysis reveals that certified companies exhibit noticeable improvements in safety outcomes over non-certified counterparts, underscoring the transformative potential of ISO 45001:2018 in fostering safer, more productive workplaces. The study recommends strategic measures to improve OHS performance in Sri Lanka’s coconut-based food manufacturing industries. Key suggestions include bolstering management commitment, strengthening communication and feedback mechanisms, conducting rigorous risk assessments, increasing employee engagement, allocating sufficient resources, promoting ISO 45001:2018 certification, and adopting a continuous improvement approach. Implementing these strategies will not only reduce workplace incidents but also enhance productivity and contribute to the sector's sustainability.
