nutrients, bacteria or algae<\/strong>.<\/p>\nOne of the most effective measures is to carry out rigorous cleaning and disinfection<\/b> of water systems susceptible to harboring Legionella. Disinfection is performed through hyperchlorination. <\/p>\nStage 3: Aerosolization<\/h3>\n
In this phase, the aim is to avoid or reduce<\/b> the generation of aerosols, a fundamental process in the transmission of legionellosis. To achieve this, actions such as controlling the location of cooling towers or increasing the size of aerosol droplets released into the environment can be implemented. <\/p>\n
To regulate these preventive measures, RD 487\/2022<\/b> has been established, which sets the hygienic-sanitary criteria for the prevention and control of legionellosis.<\/p>\n
This disease can trigger illnesses such as Legionnaires’ disease, which is a type of severe lung infection that causes cough with phlegm or pus, fever, chills, and difficulty breathing. And Pontiac fever, which is milder than pneumonia (like flu), but should still be treated by a doctor. <\/p>\n
How legionellosis is transmitted<\/h2>\n
Legionellosis is a disease that is transmitted through the respiratory tract, mainly by inhaling aerosols or aspirating water contaminated with the Legionella<\/b> bacteria.<\/p>\n
In other words, it is contracted when breathing in microparticles of water contaminated by Legionella bacteria. Water aerosolization occurs through the small droplets created when water is sprayed or when bubbles are formed in water, such as in whirlpool baths. Therefore, the smaller the droplets, the more easily they can access the respiratory tract. <\/p>\n
If this sprayed water is contaminated by Legionella, the disease will develop. The risk of contracting legionellosis varies depending on the amount of Legionella bacteria concentrated in the sprayed water and the person’s exposure time to this water. <\/p>\n

<\/p>\n
Associated Facilities:<\/h3>\n
Facilities with a likelihood of Legionella proliferation are:<\/p>\n
– Cooling towers and Evaporative condensers.<\/p>\n
– Hot Water Systems (HWS) with accumulator and return circuit. Accumulators, network, and terminals (faucets and showers). <\/p>\n
– Climatized Water Systems with constant agitation and recirculation through high-velocity jets or air injection (Spas, Jacuzzis, Whirlpool baths, etc.).<\/p>\n
– Industrial humidification systems.<\/p>\n
– Cold Water Supply (CWS) interior installation systems: Tanks, cisterns, reservoirs, network, and terminals (faucets and showers).<\/p>\n
– Hot water systems (HWS) without return circuit: such as Hot water heaters.<\/p>\n
– Ornamental Fountains.<\/p>\n
– Urban sprinkler irrigation systems: sprinklers and micro-sprinklers in gardens, grass fields, golf courses, etc.<\/p>\n
– Fire Protection Water System (FPS): Fire protection tanks, equipped fire hydrants (BIEs), and Sprinklers.<\/p>\n
– Outdoor aerosolization cooling elements: such as diffusers used in terraces and fairs.<\/p>\n
– Any other device that accumulates water and can produce aerosols, such as Dental Clinic chairs, water sweepers, etc.<\/p>\n
How to prevent Legionella?<\/h2>\n
To prevent Legionella from affecting our facilities, we must carry out the following measures:<\/p>\n
– All installations must have a particle filter according to the Technical Building Code (CTE) after the meter.<\/p>\n
– Each water system must have a check valve, according to the UNE-EN 1717 standard, which prevents water returns due to pressure loss or decrease in the supplied flow, and especially when necessary to avoid mixing water from different circuits, qualities or uses.<\/p>\n
– In cold sanitary water (AFS), the adequate concentration of free residual chlorine (FRC) and pH should be frequently controlled, ensuring water of microbiological quality, between 0.2-1.0 ppm of FRC and recommending a pH < 7.5. In hot water circuits (ACS), its temperature should be above 50\u00baC in the network to prevent its proliferation and multiplication, and 60\u00baC in Accumulators and Water Heaters. <\/p>\n
– Performing purges in water circuits, so that water is renewed weekly after its discharge. Eliminating dead ends of pipes. <\/p>\n
– Avoiding or reducing water aerosolization and exposure, by shielding installations (such as fountains, irrigation systems or cooling towers away from people), trying to make water droplets larger, watering at night hours without the presence of people, etc.<\/p>\n
– At least annually, cleaning and disinfection of the installation should be carried out by authorized companies such as Gimasur with ROESBA 0809-AND-450. <\/p>\n
