Worksheet to Identify Buildings at Increased Risk for Legionella Growth and Spread
Answer the following questions to help assess if your building needs a water management program or if certain devices within the building need a water management program to reduce the risk of Legionella growth and spread.
Building Questions 1–4
Note: The building standards discussed in CDC’s Legionella Water Management Program toolkit do not apply to single-family or small multiple-family residences (e.g., duplexes), even those with the devices in questions 6 through 8, but residents do need to take steps to protect themselves from waterborne diseases. Homeowners should follow local and state guidelines for household water use, and owners of the devices in questions 6 through 8 should follow the manufacturer’s instructions regarding cleaning, disinfecting, and maintenance.
