5 Common Questions About Legionella: Answered
What is Legionella?
Legionella is a waterborne bacterium that can pose serious risks to facilities that use water systems, such as cooling towers, HVAC units, ice machines, and even drinking fountains. It primarily infects the lungs after being inhaled via contaminated water droplets. There are over 60 species of Legionella, but the most dangerous is Legionella pneumophila, which is responsible for causing Legionnaires' disease. This condition affects the respiratory system, leading to pneumonia-like symptoms such as coughing, shortness of breath, and fever. Although rare, Legionnaires' disease can be fatal, especially for individuals with weakened immune systems, making it crucial to control Legionella in facilities where water systems are used regularly.
Where is Legionella Found?
Legionella thrives in a variety of water systems, making many commercial facilities vulnerable to contamination. Cooling towers, faucets, showerheads, and HVAC units are some of the most common places where Legionella can proliferate. Additionally, Legionella is often found in condensate drip pans and other moist environments that are not properly maintained. Areas with stagnant or slow-moving water are particularly susceptible to bacterial growth.
The bacterium prefers water temperatures between 68°F and 122°F, which are commonly found in cooling systems. This is why it’s essential to regularly test water systems and clean the areas where Legionella could accumulate.
Why is Legionella Dangerous for Buildings?
Legionella not only poses a health risk to individuals but also impacts the overall operation of a building. Water systems that are contaminated with bacteria like Legionella can operate inefficiently, leading to increased energy consumption, reduced equipment life, and in extreme cases, complete system failures.
Cooling towers, in particular, are a major source of Legionella outbreaks because they operate at the optimal temperature and pH for bacterial growth. The mist generated by cooling towers can spread Legionella throughout the facility, creating health hazards for anyone who inhales contaminated water droplets. Besides the obvious health risks, failure to control Legionella can lead to legal liabilities for building owners and operators, especially in regions where Legionella management programs are mandated by law.
How Can State Chemical Help Mitigate Legionella Risks?
State Chemical offers comprehensive Legionella management solutions tailored to the specific needs of each facility. A State Chemical representative will work closely with you to create a Legionella risk management plan, which includes regular maintenance of water systems. The plan will target areas within your facility that are most susceptible to Legionella growth and provide ongoing support to ensure that you remain compliant with regulations.
How Do I Get My Facility Tested for Legionella?
In some regions, such as specific states and provinces in North America, facilities are legally required to test for Legionella, particularly in cooling towers and other water systems. Even if your area does not mandate it, regular testing is highly recommended. State Chemical uses a trusted third-party laboratory to conduct certified Legionella tests, which provide detailed analysis and identification of the bacteria species present in your facility.
Testing is only one part of the solution. Even if you choose to conduct testing independently, State Chemical can still help you implement the best control strategies to prevent future Legionella outbreaks. A proactive approach to testing and treatment will help safeguard your building from the risks associated with Legionella.
