Legionella Risk Assessments

The Importance of Legionella Risk Assessments in Water Systems

Legionella risk assessments are crucial evaluations conducted to identify and mitigate the risk of Legionella bacteria proliferation in water systems. Legionella bacteria can thrive in various water sources, including cooling towers, hot and cold water systems, and decorative fountains, posing a significant health risk if inhaled in droplets or aerosols. Conducting Legionella risk assessments involves a thorough examination of water systems to identify potential sources of Legionella growth and transmission.

This assessment typically includes reviewing system design, operation, and maintenance practices, as well as assessing factors such as water temperature, stagnation, and the presence of biofilms. Based on the findings of the assessment, recommendations are provided to control and manage Legionella risks effectively. Regular Legionella risk assessments are essential to ensure compliance with health and safety regulations and protect the health and well-being of building occupants and the public.
