    Why Do I Need a Legionella Water Risk Assessment?

    Under the Health and Safety at Work Act in 1974, a Legionella risk assessment is a legal requirement. If you are a duty holder or are in charge of health and safety for any kind of premises, you must ensure water hygiene risk assessments are undertaken.

    This is in order to prevent the proliferation of Legionella bacteria. When humans are exposed to this bacteria in tiny water droplets called aerosols, it can lead to chronic lung infections. The most serious of these is Legionnaires’ disease, a potentially fatal form of pneumonia.

    Legionella bacteria can be found in any water system, man-made and natural. It becomes a problem when large amounts are allowed to grow and are spread through aerosol release. 

    The conditions that allow Legionella bacteria to thrive dangerously include:

    • Water temperature: Water that is consistently between 20-45 degrees Celsius provides the perfect temperature for Legionella bacteria to thrive.
    • Stagnancy: Legionella is a problem in water storage tanks because it favours stagnant water. This can affect drinking water.
    • Nutritional sources: Poor water hygiene means more bacteria, scale and sediment in your water supply. These all provide nutrients for Legionella bacteria, allowing it to thrive and spread.

    The above conditions are usually present in:

    • Water storage tanks
    • Taps
    • Showers
    • Air conditioning units
    • Spa facilities
    • Swimming pools
    • Dental apparatus
    • Healthcare properties
    • Food manufacturing sites
    • Washing facilities
    • Industrial facilities

    Can Anyone Complete a Water Hygiene Risk Assessment for Legionella?

    A “responsible person” must carry out water risk assessments for Legionella. Government guidelines stipulate that this individual must have the competence and suitable training to undertake the necessary checks. The checks need to be completed in line with legislation, including ACOP L8 and HSG274.

    Because water hygiene is so vital to the health and safety of humans, it is highly recommended to employ the services of professionals. A Legionella risk assessment from Guardian Hygiene Services will be completed by highly trained technicians with industry accreditations.

    Our trusted services will give you peace of mind as we take care of everything for you, to the highest safety standards.
