An Legionella Risk Assessment, also called LRA it is an audit that is performed to assess the possibility of Legionella infection that is present in commercial properties. It is among the more reliable testing and requires thorough assessment processes which include an extensive sampling of fluids from the location of potential contamination. A sample is collected from inside an object, which is usually one that is a structure or site that has water pipes and then the fluid is taken off-site to be analysed. A first step is the eye is inspected of any variations in texture or color within the sample. Special cameras fitted with specific lenses are utilized to examine the zones 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 principal reason for the legionella risk assessment is to pinpoint the possible causes of infection, specifically in the event that the establishment has not had its safety declared by officials in charge of local health. This is done to ensure that the person in charge can perform the necessary disinfection processes and offer suggestions on how to minimize the risk. Furthermore, the qualified person should also take into consideration the probability of being infected by airborne species. This could may include the route that could be used to contact between water and people that has been contaminated of water. In this scenario an additional assessment is performed by a different team of experts to pinpoint the exact sources of contamination.
The results of the study and recommendations derived from the risk assessment of legionella will be directly communicated to the authority responsible and the person who is responsible for taking the necessary measures to control. The most common first contact with legionella or its products is via a surface water system that transports water within the public space or commercial structure. In these cases, it is possible to require the implementation of a particular precautionary measure, which must be taken into effect immediately after the issue is recognized. In this way, the number of people who are exposed to the bacteria and its products will be reduced, which will prevent the possibility of developing the disease.
