By following the readily available guidance given in the documents listed below, and conforming with local codes and standards, the risk may be practically reduced so that outbreaks become not just infrequent but a rarity. This data excludes infections that were attributed to travel or were hospital acquired Source: Paul was an active member of HSE’s Legionella Committee and its Legionella Technical Working Group and has facilitated the development and delivery of past and current HSE intervention strategies for cibsr control of Legionella risks in workplaces.

Management and communication — This includes defining responsibility; documenting system assessment and monitoring; ensuring appropriately trained people; developing action plans; and planning communication requirements, both internally and to external bodies. This would normally be as a result of epidemiological information gathered by the local health authority. Management and communication — This includes defining responsibility; documenting system assessment and monitoring; ensuring appropriately trained people; developing action plans; and planning communication requirements, both internally and to external bodies.

Water temperatures and that viability of Legionella Source: These are used in the data in Figure 2 to show the rising number of reported outbreaks in Europe. There are a host of biocide dosing methods cisbe oxidising agents — such as chlorine dioxide and sodiumand calcium-hypochlorite — and those that do not rely on oxidization — such as the surfactant amines, chlorinated phenolics and copper salts.

Legionella Tutors – Legionella Risk Assessment

The bacteria may come from one of any number of reservoirs of water, including evaporative cooling towers, pipework and water storage tanks, but the bacteria will also be naturally present in the atmosphere, including in soil, groundwater, seawater and even water on plants. This data excludes infections that were attributed to travel or were hospital acquired Source: The successful control of Legionella is as much about management as it is technical detail.

The bacteria may come from one of any number of reservoirs of water, including evaporative cooling towers, pipework and water storage tanks, but the bacteria will also be naturally present in the atmosphere, including in soil, groundwater, seawater and even water on plants. The various codes and standards require that there should be an appropriate water safety plan.

Due to the evaporative processes within a cooling tower, and combined with particulate matter in the outdoor air, a substantial amount of solids can accumulate in a cooling tower.

The high incidence of individual cases in coincides with particularly high summer temperatures. Those who are ill or infirm, such as hospital patients, are particularly susceptible. For example, evaporative coolers used on the inlet to air conditioning systems have become very popular for applications such as data centres. In the case of an outbreak, the potential source should be identified and isolated. The high incidence of individual cases in coincides with particularly high summer temperatures.

Sinceit has been a notifiable disease in the UK. In terms of building services, the principal areas of infection have arisen from cooling towers and hot water systems, including spa pools. Since it is the inhalation of the bacteria within water aerosols that carries the principal risk, that risk can be reduced by not purposely creating aerosols, and by allowing drain down of components when not in use to remove the opportunity for water dead legs.

Dr Paul McDermott Paul has an Honours degree and PhD in microbiology and spent the first 11 years of his career in microbiology research and as a university lecturer.

Prevention is typically achieved by engineers with normal, good working practices.

There are a number of antibiotic treatments for different strains of infection from the various species of Legionellawith good recovery rates if the infection is identified early enough. This will provide nutrients for the growth of bacteria and the development of biofilms, and so needs continuous removal and monitored treatment. There are several documents and websites most freely available that provide guidance on the management processes and technical solutions:.

Particular care must be taken immediately following periods of shutdown — maybe after lack of use in winter and spring — where poorly treated systems can accumulate significant Legionella concentrations.

Those at risk from infection through Legionella are typically older than 40 years, and predominantly males who have susceptibility to infection through underlying diseases such as diabetes, chronic heart disease and smoking-related diseases.

Through appropriate design of systems such as reducing dead legs, supplying mains water direct to water outlets, keeping connecting pipework lengths to a minimum, and keeping water storage tanks accessible for cleaning but otherwise sealed, the opportunities for Legionella multiplication may be substantially cibxe.

Drift eliminators are essential to reduce the amount of makeup water carried into the atmosphere; however, some will still escape. Risk assessments for Legionella control.

The rod-shaped bacteria Figure 1 found to have caused the disease was called Legionella pneumophilain reference to the affected group of legionnaires.
