Abstract Prevention of Legionnaires' disease centres on preventing the inhalation of water aerosols contaminated with the Legionella pneumophila bacteria. In order to prevent growth of the bacteria, water systems capable of generating aerosols when restarted should be derived and kept dry during a period of disuse, and air-cooled chillers should be used in preference to evaporative coding towers. Water supplies should be stored either below 20°C or above 55°C, and care should be taken to prevent stagnation of water. All storage cisterns should be protected against the ingress of plant and animal matter, and only approved fittings and materials should be used. Cleaning and routine maintenance should be scheduled.
