What Is Legionella?

Legionella bacteria is a naturally occurring organism that can be found in natural water such as lakes, reservoirs and rivers as well as manmade purpose-built water systems. Legionella bacteria can colonise in plumbing, shower heads, water storage tanks and hot water cylinders as well as high-risk systems such as cooling towers, spas, hot tubs, pools and water features.

A low number of Legionella in such water is to be expected, but in the ‘right’ conditions the bacteria can multiply quickly, rising to dangerous levels which contaminate the water. The issue doesn’t come from ingesting the water itself but when water is aerosolised and those particles are inhaled into the lungs, they can cause Legionnaires disease.

    What Is Legionnaires Disease?

    Legionellosis (also known as Legionnaires disease) is a progressive and potentially fatal atypical pneumonia caused by the inhalation of tiny water droplets containing Legionella bacteria. The onset is relatively abrupt with a membrane covering the lungs (pleurisy), high fever, headache, muscle pains, chills, confusion, etc, which can in some cases lead to death. It is often treated in hospital with antibiotics, oxygen and breathing assistance and can take up to one year to fully recover.

    An average of 350 cases of Legionnaires disease are reported each year in the UK and it is estimated that about 12% of those who contract it in a community setting will die. The mortality rate in a healthcare setting is actually much higher and this is why it is so important to ensure that Legionella risk control is taken seriously and that all necessary precautions and measures are put in place to ensure that such things do not occur.

    Is Legionella Testing Required By Law?

    In the UK, whether you are a landlord or a business owner, you are legally required to have an up to date Legionella risk assessment in place in order to assess and control the risk of exposure to Legionella bacteria.

    It is crucial to fully understand the dangers of Legionella and take the necessary precautions to reduce the risk of exposure. The L8 Approved Code of Practice, issued by the HSE (Health & Safety Executive), outlines the measures that you must take to minimise your Legionella risk which includes things such as;

    • Identifying and assessing any potential sources of risk
    • Sufficiently manage those risks identified
    • Put in place appropriate preventative measures
    • Keep detailed and accurate records of any testing, results or work carried out

    How Do I Know If My Building Is Compliant?

    With a legal duty of care to assess and control Legionella levels and the risk of exposure, landlords, organisations and business owners are responsible for ensuring compliance with the necessary health and safety legislation.

    In the event of an outbreak of Legionnaires disease at a property you own or are in charge of, you will need to be able to provide the authorities with evidence of the appropriate control measures including an up to date risk assessment as well as management, monitoring and maintenance records.

    Failure to be able to provide adequate proof that you took every reasonable step to control the risk of Legionella exposure can result in severe penalties, legal action and in some cases even a prison sentence.

    Your responsibility

    Under the Control of Substances Hazardous to Health (COSHH) Regulations, owners and operators of all commercial premises (including: Social HousingFacilities ManagementHotels & StadiumsHealthcareEducation and Others) have a legal responsibility to control the risk of legionella bacteria in water systems. Owners and operators of all commercial properties are required to:

    • Identify and assess the sources of risk (see Legionella Risk Assessment for more information)
    • Prepare a scheme for preventing or controlling the risk
    • Appoint a person to be managerially responsible
    • Implement and manage precautions
    • Keep records of the precautions implemented

    Swiftclean legionella control services

    As a commercial business, you are obliged to keep on top of legionella testing, particularly in places such as hotels, spas, schools and social housing. Legionella Risk Assessments should be commissioned every two years and possibly more frequently if you are working with high-risk people, modifications to water systems have taken place, there has been a change in the management structure or if there is a suspected outbreak. Bacteria counts can determine if your water system is at risk of contaminating people and in that case, you can take the correct action to treat the legionella.

    There are a number of ways you can treat legionella. Hot water above sixty degrees, chlorine and other approved disinfectants are able to kill legionella – we will work with you to find the best solution for keeping legionella at bay. We will help to identify risk factors in your building and what might put people most at risk, identifying a risk level for your business and recommending how to stay on top of your legionella monitoring.

    There are a number of things you can do to be on top of legionella control such as keeping pipework short and direct, insulating pipes, using materials that don’t encourage the growth of legionella and preventing any contamination in the tank.

    Legionella thrives in stagnant water, so you should regularly check, inspect and clean water tanks. For taps or showers that might not be used regularly, it is important to run these at least once a week to prevent legionella growth. You should also clean and descale taps and showerheads once a quarter to reduce risk.

    Our years of experience in dealing with legionella and identifying risk factors in all types of businesses and homes mean we are experts and will work with you to work out a plan for your legionella monitoring – ensuring you are running a safe healthy environment whether you run a gym, swimming pool, hospital or rent out houses. We know you have a responsibility to keep people safe and we will ensure all bases are covered when it comes to your legionella control.

    Legionella Control for Dentists

    Don’t underestimate the importance of ensuring the quality of your dental unit water. With patients and surgery staff regularly exposed to water from aerosols used during treatment, failure to ensure that dental unit water lines (DUWL) are clean can cause contamination, risk spreading infection to patients and dental workers and may be a breach of Health and Safety Guidelines.

    Although cases of infection from dental surgeries are thankfully rare, there remains concern at the potential for legionella to be spread from DUWL. Contamination has become more of a concern in recent years. The biofilm on the inner surface of the DUWLs provides a favourable environment for the bacteria to gather and breed.

    Events in Scotland in 2012 showed that few preventable illnesses inspire as much media scrutiny and public concern as Legionnaire’s Disease. The fact that the bacteria is spread through droplets of water and carried in the air means it is something that can be contracted without any awareness or knowledge. It is estimated that about 12% of those who contract Legionnaire’s Disease will die. Those who survive may never fully recover.

    This places a large responsibility on dentists to maintain the quality of DUWLs by instituting infection control measures. The Health and Safety Commission’s requirements can be found in “The Control of Legionella Bacteria in Water Systems – Approved Code of Practice and Guidance”. The code of practice applies to all premises covered by the Health & Safety at Work Act 1974, including dental surgeries. All dentists are required to conduct a statutory risk assessment in their practices and, to comply with their legal duties as employers, dentists must identify and assess sources of risk and implement a scheme for preventing and controlling that risk.

    Your Responsibility

    All dentists are required to conduct a statutory risk assessment in their practices and, to comply with their legal duties as employers, dentists must identify and assess sources of risk and implement a scheme for preventing and controlling that risk.

    The aim is to ensure compliance with the Department of Health’s Health Technical Memorandum (HTM 01/05) which was introduced in 2009 as a response to emerging evidence around the effectiveness of decontamination in primary care dental practices. Practice managers should ensure that DUWLs are flushed daily. HTM 01-05 advises that at the start of each day, all DUWLs, including the three-in-one syringe, need to be purged for three minutes with either freshly distilled or RO water. Between each patient treatment, all DUWLs will require purging for 20-30 seconds and at the end of the day it is recommended to purge the DUWLs for three minutes. In addition to this, a self-contained water bottle system should be used and filled with freshly distilled or reverse osmosis water, instead of being delivered directly from the mains and dental practices are required, by law to perform a legionella risk assessment and water quality test.

    All dental practices both in the NHS and Private Sector are required to register with the Care Quality Commission and meet its registration requirements as set out in the Memorandum.

    Legionella FAQs

    How long does it take Legionnaires disease to develop?

    Legionnaires disease can develop in anything between two to ten days with flu-like symptoms such as a high temperature, fever, muscle pain, headache and coughing. If you suspect legionnaires and have breathing difficulties it is important to get medical attention as soon as possible as it can cause severe pneumonia and you may need to be on antibiotics for a few weeks. If it is left untreated it can be fatal.

    Where am I most likely to contract Legionnaires disease?

    Legionella usually thrives most in public places such as swimming pools, hospitals and offices so it is important for your facilities management to keep on top of legionella prevention. It is quite rare to contract it in your own home, but it does happen. Landlords have a duty to keep on top of legionella prevention and regular checks for the safety of their tenants.

    Can Legionella be passed from person to person?

    Legionella cannot be passed from person to person, it can only be contracted through breathing in mist from contaminated water so controlling it at the source is hugely important. Those most at risk are the elderly, smokers, alcoholics or those suffering with cancer, diabetes, chronic respiratory disease or kidney disease. This means places like retirement homes, hospitals and hospices are high-risk places and should be carefully monitored regularly.

    What can be done to prevent Legionnaires disease?

    Water should either be under twenty degrees or over sixty degrees to prevent legionella growth. Treatment chemicals are often used in swimming pools and spas and is another effective way of killing legionella. We will suggest the most appropriate way for you to treat it at your business.
