Legionella Risk Assessment

Legionella bacteria are microorganisms that pose a significant risk to human health if present in bathing water sources. Older adults or people with compromised immune systems are particularly vulnerable. The most serious condition related to Legionella bacteria is Legionnaire’s disease, a severe form of pneumonia that impacts the respiratory system. Legionella can be harmful to a person’s health if inhaled into the lungs, making contaminated shower water and steam the primary causes of infection. In order to keep employees and the public safe, it is important to assess and correct factors that may increase the risk of a potential outbreak.

The water systems that are routinely assessed include cooling towers, cold water storage tanks, hot water cylinders, domestic and safety showers and manufacturing equipment.
