Legionella Risk Assessment

Our Northern Ireland based water specialists carry out the risk assessment in accordance with the Health & Safety Executives ACoP L8 (4th Edition) and Health & Safety Guidance 274

Legionella Risk Assessment

The first step towards compliance is to carry out a legionella risk assessment of the building water services. Our specialist water consultants carry out the risk assessment in accordance with the Health & Safety Executives Approved Code of Practice L8 (4th Edition) and Health & Safety Guidance 274.

The risk assessment will address all systems where water is used or stored. Analyse the risk factors and consider the potential of the system to become contaminated with Legionella which causes Legionnaires disease.

Our Northern Ireland Water Consultants are suitably qualified, skilled and experienced and demonstrate: –

•   A good knowledge of domestic hot and cold water systems

•   A good knowledge of commercial hot and cold water systems

•   A good knowledge of legionella control measures

•   A good knowledge of sampling, analysis and investigation

   A good knowledge of the legislation and Approved Code of Practice that supports the management of legionella bacteria

   A good understanding of how to minimise the risks of legionella bacteria

In addition, the Water Consultants will hold and retain the membership of the Water Management Society to demonstrate that the Assessor is continually updated with technical documentation supporting the Health and Safety Executives approved Code of Practice L8 (4th Edition).

 

 

What is a Legionella Risk Assessment?

A legionella risk assessment is a formal way of documenting the potential hazards that are present in a workplace.  A company with 5 or more employees must record their risk assessments and the work done to improve safety. 

Techright Environmental risk assessment will include: – 

  •  Checks to ensure water storage tanks and water heaters are clean and compliant with the Water Regulations 1999.
  • Legionella testing temperatures to ensure temperatures are satisfactory for the control of Legionella
  • Recommendations based on findings (risk will be rated as Low, Medium or High)
  • Full asset register
  • Report detailing any remedial works required in order to comply with current standards
  • Recommended maintenance programme and precautionary measures
  • Identification of responsible and competent persons
  • Photographs along with highlighting any areas of concern
  • Plumbing schematic
  • Full logbook with a PDF copy stored on web based electronic database
  • Legionella awareness training for associated staff. Training can include the recording of temperatures and quarterly shower head disinfections.

    How long will the Legionella Risk Assessment Survey take?

    Firstly, to conduct a Legionella risk assessment, we will require access to all water outlets and equipment in your premises including: –

    •         Water heaters
    •         Water boilers
    •         Hot and cold water distribution pipe work
    •         Tap outlets
    •         Showers
    •         Cold Water Storage Tanks
    •         Any other water equipment

    Therefore, each asset will be surveyed and assessed for Legionella risk. On average, the time our qualified assessor spends on site is 1 hour for every 10 outlets. An assessment can take anywhere from 1 hour to 6 or 7 hours. It depends on the size of your water system and the number of cold water storage tanks, water heaters, sinks, wash hand basins etc. 

      What is Legionella bacteria?

      Firstly, Legionella are rod shaped bacteria belonging to the family legionellaceae. There are over 40 identified species of Legionella bacteria.

      Legionellosis is the collective name given to the pneumonia-like illness caused by legionella bacteria.

      Secondly, Legionella bacteria are all around in the natural environment, particularly in slow-moving surface water within lakes, rivers and ponds and soils in low numbers.

      Finally, they can become a health hazard when they settle in hot and cold water systems like water tanks, pipework, water heaters, showers and any other water equipment on your premises and with the right conditions they can grow.  

        What is Legionnaires Disease?

        Legionnaires disease can be a potentially fatal disease, caused by the inhalation of small droplets of contaminated water containing the bacterium Legionella pneumophila and related bacteria.

        Man-made hot and cold water systems are likely, if conditions deteriorate, to provide an environment where Legionella can grow, so it’s important to ensure your water systems are safe and not at risk of delivering these fatal bacteria. 

          Symptoms of Legionnaires Disease?

          The symptoms of legionnaires disease are similar to the symptoms of the flu.

          Because it is similar to the flu, it is not always easy to diagnose. A blood or urine test will be helpful in deciding whether an illness is or is not legionnaires disease.

          Symptoms include:-

          • High temperature, feverishness and chills
          • Cough
          • Muscle Pains
          • Headache, and leading on to
          • Pneumonia, and very occasionally
          • Diarrhoea and signs of mental confusion

            Legionnaires’ Infection

            People usually catch legionnaires disease by inhaling small droplets of water containing legionella bacteria deep into the lungs. Small airborne water droplets are commonly referred to as aerosols. Aerosols are formed by running a shower, Turing on a tap or from systems such as spa pools and cooling towers. Not everybody exposed to legionella will become ill.

            The higher risk groups include:-

            • People over 45 years of age
            • Smokers and heavy drinkers
            • People suffering from chronic respiratory or kidney disease
            • Anyone with an impaired immune system

            Approximately 10-15% of cases will result in death.

              Is it A Legal Requirement to Have A Legionella Risk Assessment?

              The simple answer is yes. If you have water systems in your workplace then you need to assess them for the risk of Legionella.  

              Employers, or those in control of premises (such as a landlord), have a legal duty to identify, assess and reduce the risks of exposure to legionella as any water system, with the right conditions, can be a source of the bacteria.

                In-House Control of Legionella 

                Techright Environmental provides a comprehensive training program for associated staff to manage and control the risk of exposure and reduce the likelihood of Legionella outbreak.

                The on-site training includes:

                • temperature checks
                • showerhead cleaning
                • descaling and chlorination of all water outlets

                We will give your delegates the necessary skills and equipment including a logbook. Should any temperatures be non-compliant, we will support you throughout the process to return your site to a safe and compliant standard.
