Legionella Risk Assessment

Facility Management

Protecting visitors in public facilities and commercial buildings from Legionella risk is an important responsibility of facility managers in the broader interest of public health.

Managing Legionella risk has become an increasingly challenging task because of the rising complexity of artificial water systems buildings and an increasing stock of aging buildings.

Failures in Legionella risk control can result in a shutdown of event venues, public transport or commercial buildings which cause reputational and financial damage in addition to the health damage brought to visitors.

In addition, the growth of Legionella in complex water systems of large infrastructures can have a tangible financial impact in real estate transactions or change of operator.

Legionellosis (also known as Legionnaire's disease) is a reportable disease to public health authorities. Compulsory preventive measures against the disease start with proper water hygiene in facilities. Regular Legionella tests and effective water hygiene measures are the key to successful Legionella risk control and prevention of cases of Legionellosis.

Periodic testing for Legionella in public buildings is mandatory in many jurisdictions. Large events, change of operator or usage patterns and exposure of vulnerable population warrant an additional Legionella risk assessment.
