Implementing proper maintenance strategies for water systems in large buildings or structures is the best strategy for preventing infections. How to prevent legionella in showers To prevent legionella bacteria building up in your shower, keeping showers clean and sanitary is essential. A competent person should routinely check, inspect and clean the system, in accordance with the risk assessment. If not properly maintained, hot water systems can encourage the growth of Legionella as the bacteria breeds well in warm stagnant water. To understand how to prevent Legionnaires disease, it is essential to first understand how the waterborne Legionella bacteria is able to get into the air and infiltrate our lungs.. Legionella bacteria enter the lungs held in fine droplets of water. Domestic hot-water systems are frequently implicated as the source of legionellosis (Legionnaires’ disease) outbreaks. Outbreaks of Legionnaires disease are preventable, but requires meticulous cleaning of water systems and precautionary measures that do not allow the growth of Legionella bacteria. He is the author of the book Legionellae Control in Health Care Facilities: A Guide for Minimizing Risk and three new Legionella management plans for hospitals, hotels and nursing homes. You must identify âsentinel’ outlets (furthest and closest to each tank or cylinder) for monthly checking of the distribution temperatures. Visit our updated The following precautions will help reduce the risk: The Level One investigation (initiated when there's probable basis for suspecting that water sources are contaminated with legionella, or when there is information that one case of Legionnaires' disease may exist) consists of an overview of the building water systems via a walkthrough, an identification of components that may present risk, and any recent changes in the system. Cold-water storage tanks should be cleaned periodically and water should be drained from hot water cylinders to check for debris or signs of corrosion.

Water management programs that effectively prevent Legionella growth in water systems rely on control and prevention measures, including good system design, proper facility and equipment maintenance, and routine cleaning and disinfection. He is also the editor of Legionella Enews, an international newsletter that covers outbreaks and new technology. Legionnaires disease is contracted by breathing in small droplets of water contaminated with legionella. Stagnant water favours Legionella growth.
