What is Legionella?

Legionella is a pathogenic bacterium responsible for heath conditions collectively referred to as legionellosis, including the serious, potentially fatal flu-like condition Legionnaires’ disease.

Legionella bacteria occurs naturally in aquatic environments including rivers, lakes and ponds, usually at low concentrations, but has also been found in soil and potting composts. It becomes problematic when it enters  engineered water systems where, under the right conditions, it can grow if left untreated.

Legionnaires’ disease can be contracted by humans when fine airborne water droplets, known as an aerosol, become contaminated with Legionella bacteria and are then inhaled deep in to the lungs.

Typical sources of Legionella contaminated water in engineered water systems include (but are not limited to) cooling towers and air-conditioning systems, domestic hot and cold water systems including showers, hot tubs, hydrotherapy baths, dental equipment, vehicle washing systems, industrial cutting fluids, ice-making machines, decorative fountains and misting systems.

What is a Legionnaires Disease Risk Assessment?

A Legionnaires disease risk assessment is an essential component in any well managed Legionella management and compliance process. The assessment itself typically involves the detailed examination of all man-made water systems at your premises, together with a review of the management and control processes you have in place to manage the risks associated with Legionnaires’ disease through exposure to Legionella bacteria.

… if you are an employer, you control premises or have responsibility for the health and safety of others, you will need to carry out a Legionella risk assessment of the water systems that fall under your control.

Our specialist risk assessments are carried out in accordance with the requirements of BS 8580:2010 and our detailed reports are designed to ensure the risks associated with Legionnaires’ disease are clearly identified, fully assessed and then summarised in a “Plain English” style to help reduce your risk and to help you meet the compliance standards set by the Health & Safety Executive in this important area.

Do I need a Legionnaires Risk Assessment?

In the UK the requirement for a Legionella risk assessment is identified in the Health & Safety Executives ACOP L8 document “Legionnaires’ disease: The control of legionella bacteria in water system”, which is underpinned in law by the Health and Safety at Work etc. Act 1974, the Control of Substances Hazardous to Health Regulations 2002 (COSHH) and the Management of Health and Safety at Work Regulations 1999.

What does all this mean for you? Well… if you are an employer, you control premises or have responsibility for the health and safety of others (referred to as the statutory duty holder), you will need to carry out a Legionnaires risk assessment of the water systems that fall under your control.

If you ignore the law, or fail to carry out a suitable risk assessment, you could find yourself under investigation, or more seriously in court if an outbreak of Legionnaires’ disease is traced back to your place of work.

Who Can Carry Out this type of Risk Assessment?

The Health & Safety Executive require that the assessment of risk from Legionella bacteria is carried out by suitably trained people who are competent to perform such tasks. This typically means experienced, suitably trained Legionella risk assessors.

However, it may be possible for you, or someone within your organisation to complete a simple water safety risk assessment if you have suitable training and a knowledge of both health and safety, and water systems.

Although, if your water systems are more complex or the risks are considered to be higher, we would strongly recommend that you get expert assistance from us.

Water Treatment Services fully trained Legionella risk assessors can perform a comprehensive assessment of the risks presented by Legionella bacteria that you can rely on with complete confidence, and that can be used to form the foundation on which your future risk management activities are based.

What Type of Water Systems can Create a Legionnaires’ Risk?

A risk assessment survey for Legionnaires’ disease must identify and assess all water systems where Legionella bacteria could grow, the potential for such systems to create an aerosol, the potential for people to be exposed to that aerosol and their susceptibility to the disease.

All water systems present within or associated with a building, whether in use or not need to be included in the assessment of risk. While many building owners and operators may discount water systems that are used infrequently as being of little or no risk, it is important to understand that such little used outlets and water systems can often present the highest risk so should never be ignored.

However, the assessment should also review in detail the following water systems which are known to represent an increased level of risk:

  • Cooling systems, cooling towers & evaporative condensers

    Cooling systems and in particular cooling towers and evaporative condensers which are known to present a significant risk.

  • Hot & cold water systems

    Domestic hot and cold water systems including showers, spray taps etc.

  • Hot tubs & spa pools

    Hot tubs, spa pools and hydrotherapy baths.

  • Fountains & water features

    Decorative fountains and water features.

  • Dental water lines

    Dental equipment using water, especially dental water lines.

  • Industrial cutting fluids

    Industrial metalworking fluids and other cutting fluids.

  • other engineered water systems

    All other engineered water systems that can harbour legionella bacteria and have the potential to create and disperse an aerosol.

What Other Measures are required to comply with the Law?

A comprehensive Legionella risk assessment should be seen as only the first stage in any good risk management process for the control and prevention of Legionnaires’ disease in the work place.

Additionally, to fully comply with your legal responsibilities the statutory duty holder should also:

  • Responsible Person

    Appoint a suitably competent person who has sufficient authority and knowledge of the water systems to ensure compliance with the law. This person is commonly referred to as the “responsible person”.

  • Written Scheme of Control

    Prepare a written scheme of control for preventing or controlling the risk associated with Legionnaires’ disease and the growth and proliferation of Legionella bacteria.

  • Legionella control

    Implement, manage and monitor the Legionella control measures required.

  • Record Keeping

    Maintain accurate records of all the Legionella control measures implemented.

Water Treatment Services offer a comprehensive range of expert risk assessment, environmental hygiene and water safety management solutions to ensure the risks associated with Legionnaires’ disease are managed to meet the compliance standards set by the Health & Safety Executive in their ACOP L8.

How often do I Need to update my Risk Assessment?

The UK’s Health & Safety Executive previously required that Legionella risk assessments be reviewed every two years but since late 2013 this is now no longer the case.

Those organisations required to maintain a formal Legionella risk assessment need to review their risk assessment regularly and specifically when there is reason to believe that the original assessment of risk may no longer be valid. The primary aim is to ensure that the risk assessment is used as a “living document”, i.e. one that is used and reviewed regularly to ensure it remains up-to-date and relevant at all times.

Although there is no specific review period for your risk assessment we recommend that it be reviewed at least every two years as a long-stop, but sooner if things change or you suspect it is no longer valid.

Situations requiring an earlier review of your Legionella assessment could include:

  • Engineering Modifications

    If there are significant changes or modifications to the water system.

  • System Change of Use

    The use of the water system has changed.

  • Building Change of Use

    The use of the building has changed.

  • New information

    New information about risks or control measures becomes available.

  • People changes

    Key personnel involved in the control process have changed.

  • Lack of control

    The legionella control measures employed are no longer effective.

  • Outbreak of Legionnaires’ disease

    A case of Legionnaires’ disease or legionellosis is linked to the water system.

You should also regularly review your own management and communication procedures as appropriate.
