The Legionella Risk Assessment, also called LRA it is an audit that is performed to assess the risk of Legionella infection that is present in commercial properties. It is among the more reliable testing and is a thorough evaluation procedure that include an extensive sampling of fluids from the location of potential contamination. The sample is taken from the inside of the structure, typically one that is a structure or site that has water pipes and then the fluid is taken away from the site to be analyzed. In the beginning, the eye is inspected of any modifications in the color or texture within the sample. Special cameras fitted with specific lenses are utilized to examine the zones of contamination. Based on this initial report the ultimate Legionella Risk Assessment is carried out and the probable places for the bacteria can be identified.
The main reason for an assessment of risk for legionella is to determine the most likely causes of infection, specifically when the place hasn’t had its safety declared by Health authorities in the local area. This is done to ensure that the qualified person is able to execute the appropriate disinfection methods and offer suggestions on how to minimize possible risks. Furthermore, the qualified person will also be able to assess the probability of being infected by airborne organisms, which may include the route that could be used to contact between humans and water that has been contaminated of water. In this instance the assessment will be performed by a different team of experts to pinpoint the sources of contamination.
The results of the study and the recommendations from the risk assessment of legionella will be made available directly to the responsible authority as well as the expert who will be responsible for carrying out the control measures. The most common first contact with legionella or its products occurs through a surface-water system that transports water within an area that is public or commercial structure. In these cases, it is possible to require the creation of a specific precautionary measure, which must be put into place immediately after the issue is identified. In this way, the number of people exposed to bacteria and its products will be minimized, thus preventing the possibility of developing the disease.
