The Legionella Risk Assessment, also called LRA it is an audit that is that is conducted to determine the possibility of Legionella infection in commercial properties. It is among the more reliable testing and requires thorough assessment processes which include extensive fluid sampling from the location of potential contamination. A sample is collected from the inside of the structure, typically an office building or site that has water pipes and then the liquid is pumped off-site to be analysed. In the beginning, the eye is inspected of any modifications in the color or texture within the sample. Specially designed cameras with specialized lenses are utilized to examine the regions of contamination. Based on the initial data the ultimate Legionella Risk Assessment is carried out, and the possible areas for the bacteria can be determined.
The main objective of the legionella risk assessment is to pinpoint the possible causes of infection, especially when the place hasn’t already been certified safe by Health authorities in the local area. This is done to ensure that the qualified person is able to perform the necessary disinfection processes and offer suggestions on how to minimize the risk. Additionally, the knowledgeable person will also be able to assess the possibility of being infected by airborne organisms, which may include the route that could be used to contact between water and people that has been contaminated of water. In this instance the assessment will be conducted by a separate team of experts to pinpoint the sources of contamination.
The results of the study and recommendations derived from the risk assessment for legionella will be directly communicated to the responsible authority as well as the expert who will be responsible for carrying out the control measures. Most often, the first encounter with legionella, or the product it produces, is via a surface water system that transports water within the public space or commercial establishment. In these cases, it is possible to require the creation of a specific control measurethat should be put into place when the issue is identified. So, the amount of people who are exposed to the bacteria and its components can be minimized, thus preventing the risk of developing the disease.
