Note: Ecosafe has developed a Legionella specific risk rating matrix, integrating the Legionella Causation Chain and Ecosafe’s extensive knowledge of Legionella bacteria with Ecosafe’s extensive knowledge of Legionella management standards/guidelines and essential knowledge on systems that have an intrinsic risk for Legionella proliferation and dissemination. The extrapolated risk scores and profiles will provide the basis for determining priority actions and control programs following the risk assessment.
