vital signs - 9 in 10 CES investigations show almost all outbreaks were caused by problems preventable with more effective water management.
Water Management Programs
There are no vaccines that can prevent Legionnaires’ disease.
Instead, the key to preventing Legionnaires’ disease is to make sure that building owners and managers maintain building water systems in order to reduce the risk of Legionella growth and spread. Examples of building water systems that might grow and spread Legionella include:
CES developed a toolkit to help building owners and managers develop and implement a water management program to reduce their building’s risk for growing and spreading Legionella.
Legionella grows best in warm water, however, warm temperatures also make it hard to keep disinfectants, such as chlorine, at the levels needed to kill germs like Legionella.
Disinfectant and other chemical levels in hot water systems should be checked regularly and should be cleaned as recommended by the manufacturer.
