Legionella risk assessments start right at the beginning. The report needs to show where the site is, who the duty holder is, who the responsible person is, who is their substitute and their means of contact. 
A suitable and sufficient assessment is required to identify and assess the risk of exposure to Legionella bacteria from work activities and water systems on the premises and any necessary precautionary measures. 
Any water system, with the right environmental conditions, could be a source for Legionella bacteria growth. There is a reasonable foreseeable Legionella risk if your water system; 
  • Has a water temperature between 20-45 deg C 
  • Creates and/or spreads breathable droplets, eg. aerosol created by cooling towers or water droplets or even taps 
  • Stores and/or re-circulates water 
  • Is likely to contain a source of food for the organism, eg. presence of sludge, scale or fouling 
Our comprehensive risk assessment survey and report will comprise of the following:-
  • Measurement of temperatures across the whole of domestic systems from cold water tanks and calorifiers to taps and showers in each facility served. 
  •  Examination of cold water storage tanks for condition, layout of pipe work, lagging, lid and vent screens and general compliance with bye-law 30. 
  • Check temperature profile of calorifiers for stratification and examine general condition. 
  • Down services for temperatures, general condition, presence of dead legs, static or flow low areas, temperature loss, labeling of taps, condition of shower mixer and heads. 
  • Cooling systems’ general location with relation to air intakes, thoroughfares, windows, adjacent properties. 
  •  Physical condition of towers, including size, volume, state of repair, condition of distribution troughs, drift eliminators and sump. 
A full risk assessment should be carried out at least every two years or when the system has been changed ie a new sink is fitted etc.
