Legionaires Disease What is Legionaires’ disease? Legionaires’ disease is a potentially fatal form of pneumonia which kills between 5% and 15% of those infected and is caused by Legionella bacteria. Legionella bacteria can also cause less serious illness, such as Pontiac or Lochgoilhead fever. Legionaires’ disease usually develops 5–6 days after infection but may take longer. Where can Legionella bacteria multiply? Hot and cold water systems including storage tanks/cisterns Any system or part of a system where the water is warm, i.e. between 20°C and 45°C, Pipes with little or no water flow (this includes unoccupied areas) Slime (biofilm) and dirt on pipes feeding showers and taps and tank surfaces Rubber and natural fibres in washers and seals Water heaters and hot water storage tanks Scale and corrosion in storage vessels, pipes, showers and taps Flexible hoses and artificial rubber seals. These situations and conditions encourage the growth of Legionella bacteria and increase the risk of infection for visitors and staff. Reducing the risk Are your colds water tanks regularly inspected in line with HSE guidance? Are tap temperatures taken in line with HSE guidance? Are there areas of your water system with no flow? Are showerheads, hoses and taps free from scale? Are your water heaters and hot water storage tanks disinfected in line with HSE guidance? Is your cold water stored within the correct temperature range in line with HSE guidance? Is there a record of all the above being carried out? Has your building got a valid up to date risk assessment?
