The below section will assess if the water is stored between 20-45 degrees (ideal temperatures for bacteria multiplication), the cleanliness of all storage vessels and ensure these are free from scale, rust, sludge and other deposits which may support legionella bacterial growth.

Showers

• Showers -Basic requirements
  
  Because of their design showers are regarded as high risk, not least because of the close proximity of aerosol to the user of the shower.
  
  Shower heads should be removed, disinfected, de-scaled and cleaned by the occupier quarterly or as indicated by the rate of fouling to control the risk of bacterial build up. More information on how to undertake this task can be found in the tenant guide left on site at the time of assessment.

• undefined

Risk banding

• Risk indicators within the above sections are defined as follows:
  
  Items highlighted RED are considered to be HIGH risk and prompt action is required to reduce and control any potential growth and spread of harmful legionella bacteria.
  
  Items highlighted AMBER are considered to be MODERATE risk and action is required within one month to reduce and control any potential growth and spread of harmful legionella bacteria.
  
  Items highlighted GREEN are considered to be LOW risk and no further action is required at this time.
  
  

Overall property rating

• The below is an overall risk rating summary of the property taking into account all areas of the water system and outlets assessed.

Review

• A review of this assessment should be carried out regularly (at least every two years) and whenever there is reason to suspect that it is no longer valid for example if any of the below apply:
  
  *A change to the water supply system or its use;
  *Any alteration to the use of the building where the system is installed;
  *New information becomes available about the risks or control measures;
  *The results of checks indicating that control measures are no longer effective;
  *A case of legionnaires disease/legionellosis associated with the system.
