    What does a Legionella Risk Assessment cover?

    The assessment takes into account the following factors:

    • Water Temperature
    • Water Stagnation
    • Potential for Aerosol Formation
    • Heat Gain / Loss Potential
    • Condition of the Water
    • Condition of all water systems
    • The Susceptibility of persons exposed on site.

    How often do I need a Legionella Risk Assessment?

    (HSG 274 (part 2), page 53)The risk assessment should be reviewed regularly and whenever there is reason to believe the original assessment may no longer be valid, for example:

    • Where there have been changes to plant, the water system or its use
    • Where there have been changes to the use of the property
    • Where new information about risk or control measures have become available
    • Where temperature monitoring indicates that control measures are no longer effective

    The risk assessment would include all hot and cold water services. All information would be recorded on audit forms and collated within a single document. This document will be supplied to the client in either PDF or physical folder format.

    Temperature measurements would be completed, checked and evaluated. The following standards should be met:

    • Hot water stored at 60°C and above.
    • Hot water at outlets to be a minimum of 50°C within one minute of running
    • Cold water stored below 20°C
    • Cold water at outlets to be a minimum of 20°C within two minutes of running

    A colour schematic drawing will be produced showing a layout of water systems within the property.

    All areas requiring remedial action would be covered in the recommendations section of the report. A written quotation for these works will be made available to the client upon request.

    Keeping Records

    Keeping Records

    If you have five or more employees you have to record any significant findings, including those identified as being particularly at risk and the steps taken to prevent or control risks. If you have less than five employees, you do not need to write anything down, although it is useful to keep a written record of what you have done.

    Records should include details of the:

    – Person or persons responsible for conducting the risk assessment, managing, and implementing the written scheme
    – Significant findings of the risk assessment
    – Written control scheme and details of its implementation
    – Details of the state of operation of the system, ie in use/not in use
    – Results of any monitoring inspection, test or check carried out, and the dates

    These records should be retained throughout the period for which they remain current and for at least two years after that period. Records kept in accordance with (e) should be retained for at least five years.
