Process Safety Management (PSM) plays a crucial role in preventing or reducing the risk of catastrophic releases of hazardous chemicals, which can lead to significant health consequences, fires, explosions, and loss of life. Historical industrial disasters such as the Texas BP refinery explosion highlight the critical need for robust and integrated PSM systems to prevent both human and financial losses. Effective implementation of PSM hinges on the integration of its constituent elements. While literature emphasizes interconnections among PSM components outlined in OSHA's 29 CFR 1910.119, a systematic mapping of these interrelationships remains underexplored. This study presents a matrix-based approach to visualize and analyze the integration of seven critical PSM elements: Employee Participation (EP), Contractor Management (CONC), Hot Work Permits (HWP), Incident Investigation (II), Emergency Planning and Response (EPR), Compliance Audit (CA), and Trade Secrets (TS). The matrix was constructed using regulatory mandates, evidence from scholarly literature and industry guidelines. The results identify EP and CONC as central integration nodes, demonstrating the highest degree of interconnectivity and frequent citation in OSHA enforcement records. These findings underscore the importance of coordination, information flow, and organizational learning in sustaining effective PSM implementation. From a practical perspective, the proposed matrix offers a diagnostic tool for safety managers to support PSM audits, contractor oversight, training design, and the development of integration-focused digital safety dashboards.
