IMPLEMENTATION OF PROCESS SAFETY MANAGEMENT PRACTICES IN ACTIVE PHARMACEUTICAL INGREDIENT MANUFACTURING

Active Pharmaceutical Ingredient (API) manufacturing involves complex chemical processes, hazardous substances, flammable solvents, high temperatures and pressures, reactive intermediates, toxic materials, and specialized process equipment. These characteristics create the potential for fire, explosion, toxic release, chemical exposure, equipment failure and other major incidents. Effective Process Safety Management (PSM) is therefore essential for controlling process-related hazards and protecting workers, assets, the environment and pharmaceutical production. This research examines the implementation of Process Safety Management practices in API manufacturing facilities. The study proposes an integrated framework incorporating process safety information, process hazard analysis, Hazard and Operability Study (HAZOP), operating procedures, management of change, mechanical integrity, permit-to-work systems, emergency preparedness, incident investigation, employee participation and safety performance monitoring. Pharmaceutical quality-risk-management principles are also relevant because ICH Q9(R1) provides a structured approach to risk assessment, control, communication and review across the pharmaceutical lifecycle, including drug-substance manufacturing. European Medicines Agency (EMA)+1 The proposed methodology combines literature review, site observation, employee questionnaires, interviews, document review and HAZOP/HIRA analysis. A risk-based framework is developed to identify gaps in process safety management and recommend appropriate corrective measures. The research emphasizes that effective PSM should be treated as a continuous management system rather than as a collection of individual safety procedures.
