This paper presents a few results of a work aiming at providing the biogas industry with practical tools to protect workers and environment. Biological contamination, Fire and Explosive Atmosphere are the main hazards. The technical and organizational measures, aiming at preventing or mitigating them, have been identified and classified by means of the “bowties” technique. From this analysis, a structured safety check list has been derived. The checklist is a valuable support for the plant operator to evaluate periodically the actual effectiveness of the overall safety measures and to address a safer management of the plant.
