Legionella is a bacteria found in freshwater that, when spread through building water systems, can cause Legionnaires’ disease when it comes into contact with humans.
Also called legionellosis, this form of atypical pneumonia causes a host of unpleasant symptoms, including shortness of breath, nausea, high fever, headaches, muscle pains, vomiting, diarrhea, or even death. Legionnaires’ disease is a serious illness that sends an estimated 8,000 to 18,000 people in the United States to the hospital each year. Fortunately, legionella growth can be avoided by taking the following measures to ensure the safety of building occupants.
1. Clean your heat exchanger.
Since heat exchangers are used to transfer heat between fluids, regularly cleaning your heat exchanger is a sound measure to help avoid legionella growth. Keep up proper maintenance and replacements as necessary and according to heat exchanger and manufacturer recommendations.
2. Maintain a proper cooling water system.
Invest in cooling tower cleaning services to maintain a healthy system. Know when you may need a cooling tower renovation or cooling tower refurbishment.
3. Use a reliable wastewater treatment service.
Wastewater is one of the many water sources that can become contaminated with legionella.
4. Have a robust water management plan.
Staying on top of all required maintenance is essential to preventing the growth and spread of legionella. Follow the CDC’s guidelines for an effective water management program. Make sure everyone involved in building maintenance is well-versed on the necessary measures to take in order to sustain safe, healthy water systems.
Since legionella is typically spread by breathing in mist from infected water sources, any source of water can be potentially contaminated and should be maintained for safety. Hot tubs, fountains, and other seemingly harmless structures can be breeding grounds for legionella bacteria. Taking the time to keep up with all maintenance guidelines is crucial to ensuring the health and safety of all building occupants and employees.
