• 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 like those found in this property.
  
  The Control of Hazardous Substances Regulations and Health and Safety Executive Approved Code of Practice (L8) The Control of Legionella, require that the Responsible Person undertake Risk Assessments and implement schemes of control for the elimination, reduction or control of Legionella
  

• Describe property type:

• Describe type of cold water system e.g. Mains feed or from storage tank:

• Describe type of hot water system e.g. Mains feed via combi boiler or from storage tank:

Risk categories

• 1. Water outlet temperature

• Is cold water temperature at outlets below 20 degrees centigrade?

  Yes

  No

  N/A

• Is the hot water temperature above 50 degrees centigrade at outlets?

  Yes

  No

  N/A

• Cold water must flow from outlets at below 20 degrees centigrade and hot water above 50 degrees centigrade to minimise risk. If temperatures are too low/high then adjustments need to be made to the system such as lagging of pipework or adjustment of temperature settings for hot water.
  
  

• 2. Cold water storage tanks

• Is there one present?

  Yes

  No

• Location:

• Upload picture

  Media

• Does it have a tight fitting lid?

  Yes

  No

  N/A

• Is the water in the tank clean and free from rust, debris, scale and organic matter?

  Yes

  No

  N/A

• Upload picture

  Media

• Is the temperature of the water in the tank below 20 degrees centigrade?

  Yes

  No

  N/A

• If any debris etc is present in the system it should be drained and thoroughly cleaned. If debris is from the tank itself then the tank may need to be replaced. All cold water tanks should have tight fitting lids to prevent debris entering the system. The water in the tank should be below 20 degrees centigrade and the tank should be insulated to prevent the temperature rising above this level.
  
  Identify any defect/risk and related recommendations associated with cold water storage. If any action is required identify responsible person:-

• Defect:

• Risk:

  Low

  Medium

  High

• Recommendation:

• Responsible person: Landlord/tenant/other

• 3. Hot water

• Is the temperature setting on the boiler and/or hot water tank such that the hot water is heated to and stored at a temperature of 60 degrees centigrade?

  Yes

  No

  N/A

• Upload picture of the boiler

  Media

• NB: if the temperature is set above 60 degrees centigrade this can cause scalding to users.
  
  The temperature setting on the boiler and/or hot water tank should be set and maintained at 60 degrees centigrade.
  
  Identify any defect/risk and related recommendations associated with hot water. If any action is required identify responsible person:-

• Defect:

• Risk:

  Low

  Medium

  High

• Recommendation:

• Responsible person: Landlord/tenant/other

• 4. Little used outlets

• Are all water outlets used more than once per week?

  Yes

  No

  N/A

• If no, identify outlet & location:

• Any little used outlets should be flushed through weekly by running water through the outlet for at least 2 minutes. Aerosol production should be minimised during this process.
  
  Identify any risks and related recommendations associated with little used outlets. If any action is required identify responsible person:-

• Defect:

• Risk:

  Low

  Medium

  High

• Recommendation:

• Responsible person: Landlord/tenant/other

• 5. Shower heads

• Are there any showers in the property?

  Yes

  No

• If yes, identify location:

• All shower heads should be cleaned, disinfected and descaled at least once every 6 months. Aerosol production should be minimised during this process.
  
  Identify any risks and related recommendations associated with shower heads. If any action is required identify responsible person:-

• Defect:

• Risk:

  Low

  Medium

  High

• Recommendation:

• Responsible person: Landlord/tenant/other

• 6. Dead legs and redundant pipework.

• Are there any dead legs known in the system?

  Yes

  No

• Any dead legs in pipework should be removed or the system altered so that water flows through all pipework on a regular basis.
  
  Identify any risks and related recommendations associated with dead legs. If any action is required identify responsible person:-

• Defect:

• Risk:

  Low

  Medium

  High

• Recommendation:

• Responsible person: Landlord/tenant/other

• 7. Unoccupied properties

• Is the property mainly occupied for long periods of time?

  Yes

  No

  N/A

• If no, please establish period of time the property is unoccupied:

• During periods of unoccupancy all outlets on hot and cold water systems should be flushed through at least once a week for at least 2 minutes. For long periods consider draining the system. Make sure that the system is flushed through when it is re-occupied by running all outlets for at least 2 minutes. Aerosol production should be minimised during this process.
  
  Identify any risks and related recommendations associated with unoccupancy. If any action is required identify responsible person:-
  

• Defect:

• Risk:

  Low

  Medium

  High

• Recommendation:

• Responsible person: Landlord/tenant/other

• 8. Review

• The assessment is complete and should be reviewed regularly (at least once a year) and specifically when there is reason to suspect it is no longer valid. You should ensure that the recommendations above are implemented and any existing controls maintained.
