Points Of Risk

Learn to identify locations and potential causes of Legionella risks.

Outbreaks of Legionella bacteria, which can cause Legionnaires’ disease, are a particular concern at healthcare locations such as hospitals, nursing homes, and long-term care facilities. The potential for a widespread outbreak is also a challenge for buildings in the hospitality industry, such as hotels, motels, and resorts.

Successful mitigation of Legionella requires identifying where bacteria may exist in your water system, and understanding the underlying conditions that may allow outbreaks to occur.


Point of Source

These risks are located within the equipment and plumbing that treat, conduct, and distribute water throughout your facility. Evaluate how your system takes incoming water from the municipality and trace the flow from your mechanical room into and out of such equipment as heaters, chillers, and cisterns.

Point of Use

These risks are located wherever people interact with the water distributed throughout your facility. Obvious places to look are faucets, showerheads, ice machines, drinking fountains, and decorative fountains. But you will also want to look at any equipment that uses water, such as hot tubs and hydrotherapy spas.

Points of Condition

These risks are often overlooked… the underlying conditions that can make your water system more vulnerable to Legionella. These conditions can exist in locations throughout your facility including points of source and points of use and are all precursors to a potential Legionella outbreak and or recurrence.
