Holistic health and environmental risk assessment of PM and bioaerosol emissions in hospital waste and wastewater departments using FMEA and DMRA methods.

ABSTRACT: Bioaerosol and particulate matter (PM) from hospital waste and wastewater pose significant pathogen transmission and workplace safety risks to healthcare workers and surrounding communities, requiring thorough risk assessments. This study pioneers a comprehensive risk assessment of PM and bioaerosol emissions in waste disposal and wastewater treatment departments across four Iranian hospitals, employing cutting-edge methodologies like Failure Mode and Effective Analysis (FMEA) and Decision Matrix Risk Assessment (DMRA) to enhance the precision and efficacy of risk evaluation in these high-stakes environments. The study systematically identified 15 primary risk sources, with Risk Priority Numbers (RPN) ranging from 168 to 900. The investigation involved experts, focusing on evaluating healt
