Legionella Risk Assessment Procedures

Legionella Risk Assessment Procedures >> In the UK the Health and Safety Executives' ACoP L8- Approved Code of Practice and guidance titled – “Legionnaires' disease -The control of legionella Bacteria in water systems” sets out guidance for the procedures of legionella risk assessment

23:          A suitable and sufficient assessment is required to identify and assess the risk of exposure to legionella bacteria from activities and water systems on the premises and any necessary precautionary measures. The assessment is carried out by or on behalf of:

(a)    The employer, where the risk from their undertaking is to their employees or to others; or

(b)   A self-employed person, where there is a risk from undertaking to themselves or to others; or

(c)    The person who is in control of premises or systems in connection with work where the risk is present from systems in the building (e.g. responsibility for its maintenance).

24:          In conducting the assessment , the person on whom the statutory duty falls is required to have access to competent help to assess the risks of exposure to legionella bacteria in the water systems present in the premises and the necessary control measures.

25:          The assessment should include identification and evaluation of potential sources of risk and:

(a)    The particular means by which exposure to legionella bacteria is to be presented, or

(b)   If prevention is not reasonably practicable, the particular means by which the risk from exposure to legionella bacteria is to be controlled.

26:          Where the assessment demonstrates that there is no reasonably foreseeable risk or that risks are insignificant and unlikely to increase, no further assessment or measures are necessary. However, should the situation change, the assessment needs to be reviewed and any necessary changes implemented.

27:          The assessment needs to be reviewed regularly and, in any case, whenever there is reason to believe that the original assessment may no longer be valid.
