18-26: Legionnaires’ Disease Risk Management: First Requirement for CoolingIt is usually recognized that a Cooling Tower System needs water treatments and a maintenance program to prevent the transmission of Legionnaires Disease. Is it enough? Referring to the ecology of Legionella pneumophila in the water system, various case studies, standards or guidelines, the author will illustrate how a risk analysis and consequently a risk management program are the first requirements for operating a Cooling Tower System safely.
