What is Legionnaires’ Disease?
Legionnaires’ Disease is a pneumonia like illness caused by the Legionella bacteria and can be fatal.
The infection is caused by breathing in small droplets of water contaminated by the bacteria.
The disease cannot be passed from one person to another.
Legionella bacteria are found in the natural environment and may contaminate and grow in water
systems, including domestic hot and cold water systems. They survive low temperatures and thrive
at temperatures between 20 – 45°C if the conditions are right. They are killed by high temperatures
at 60°C or above.
How do I carry out a Legionella risk assessment?
The purpose of carrying out a risk assessment is to identify and assess any risks in the water system.
The competent/ responsible person should understand water systems and any associated equipment,
in order to conclude whether the system is likely to create a risk from exposure to Legionella, and
should be able to identify whether:
1. Water is stored or re-circulated as part of your system.
2. The water temperature in some or all parts of the system is between 20-45 °C.
3. There are sources of nutrients such as rust, sludge, scale and organic matters.
4. Conditions are present to encourage bacteria to multiply.
5. It is possible for water droplets to be produced and, if so, whether they could be dispersed over a
wide area, e.g. showers and aerosols from cooling towers.
6. It is likely that any of your employees, residents, visitors etc. are more susceptible to infection due to
age, illness, a weakened immune system etc. and whether they could be exposed to any
contaminated water droplets.
