CDC releases toolkit to reduce risk of Legionella

The Centers for Disease Control and Prevention (CDC) released a new toolkit to prevent Legionnaires’ disease outbreaks. The toolkit builds off of ASHRAE 188: Legionellosis: Risk Management for Building Water Systems.

The toolkit provides an easy-to-understand interpretation of ASHRAE Standard 188, as well as worksheets, checklists and scenarios of common water-quality problems. It also contains special sections and considerations for health care facilities.

In the last year, about 5,000 people were diagnosed with Legionnaire’s disease and more than 20 outbreaks were reported to the CDC. The most common source of building-associated Legionnaires’ disease outbreaks was drinkable water (56 percent), such as water used for showering, followed by cooling towers (22 percent), and hot tubs (7 percent).
