Production of hydrogen rich gas from the gasification of biomass to replace fossil fuels has become a common interest worldwide. One of the potential biomass in Malaysia to produce hydrogen rich gas is empty fruit bunch (EFB) from oil palm (Elaeis guineensis). Numerous researchers have carried out studies on hydrogen production using biomass but there are limited researches on the hazards analysis incorporated in the gasification process of EFB. This paper presents the hazards identification and risk reduction of the gasification process by using EFB as a feedstock. The research aims to incorporate safety needs to the gasification process of EFB for safe operation in the future. The process hazards analysis has been carried out on process unit namely fire burner, feeding hopper, fluidised bed reactor and cyclone. The potential hazard, possible causes, risk and consequences of the process unit were analysed. Based on the analysis, the major hazards identified in the process are overpressure and over temperature followed by the release of hydrogen gases. Safe by design is the most effective risk reduction strategy since it can eliminate the hazards from the source by having inherently safer design of the hydrogen process plant.
