LEGIONELLA RISK ASSESSMENT SERVICE INFORMATION

Legionella Risk Assessment

Legionnaires’ disease is a potentially fatal form of pneumonia caused by the inhalation of small droplets of contaminated water containing Legionella. All man-made hot and cold water systems are likely to provide an environment where Legionella can grow.

How To Keep Compliant With ACOP L8 – Legionella Risk Assessments

We can carry out Legionella risk assessments of your water systems to make sure that you are compliant. We can also design maintenance systems to reduce or eliminate the risk from legionella bacteria, keeping our clients compliant with regulation standards (HSG274 and Approved Code of Practice ACOP L8, for example).

If you are an employer, or someone in control of premises, including landlords, you must understand the health risks associated with legionella. Sherpa can help by undertaking a Legionella Risk Assessment for your business.

  • identify and assess sources of risk
  • managing any risks
  • preventing or controlling any risks
  • keep and maintain the correct records
  • identify and assess sources of risk

Duties under the Health and Safety at Work etc Act 1974 (HSWA) extend to risks from legionella bacteria, which may arise from work activities. The Management of Health and Safety at Work Regulations (MHSWR) provide a broad framework for controlling health and safety at work. More specifically, the Control of Substances Hazardous to Health Regulations 2002 (COSHH) provide a framework of actions designed to assess, prevent or control the risk from bacteria like Legionella and take suitable precautions. The Approved Code of Practice: Legionnaires’ disease: The control of Legionella bacteria in water systems (ACOP L8) contains practical guidance on how to manage and control the risks in your system.

Carrying Out A Legionella Risk Assessment Responsibly

You may be qualified and competent to carry out the Legionella Risk Assessment yourself but, if not, you should call on help and advice from Sherpa Environmental.

Sherpa will document your water systems, the equipment associated with the system such as pumps, heat exchangers, showers etc, and its constituent parts. Identify whether they are likely to create a risk from exposure to legionella bacteria, and whether:

  • the water temperature in all or some parts of the system is between 20–45 °C
  • water is stored or re-circulated as part of your system
  • there are sources of nutrients such as rust, sludge, scale, organic matter and biofilms
  • the conditions are likely to encourage bacteria to multiply
  • it is possible for water droplets to be produced and, if so, whether they can be dispersed over a wide area, e.g. showers and aerosols
  • it is likely that any of your employees, residents, visitors etc are more susceptible to infection due to age, illness, a weakened immune system etc and whether they could be exposed to any contaminated water droplets

The Legionella Risk Assessment Will Include:

  • management responsibilities, including the name of the competent person and a description of your system
  • competence and training of key personnel
  • any identified potential risk sources
  • any means of preventing the risk or controls in place to control risks
  • monitoring, inspection and maintenance procedures
  • records of the monitoring results and inspection and checks carried out
  • arrangements to review the risk assessment regularly, particularly when there is reason to suspect it is no longer valid

If you conclude that there is no reasonably foreseeable risk or the risks are low and are being properly managed to comply with the law, your assessment is complete. You may not need to take any further action at this stage, but any existing controls must be maintained and the assessment reviewed regularly in case anything changes in your system.

Managing The Risk From Legionella Bacteria

As an employer, or person in control of premises, you must appoint someone competent to help you meet your health and safety duties and to take responsibility for controlling any identified risk from exposure to legionella bacteria. A competent person, often known as the responsible person, is someone with sufficient authority, competence, necessary skills, knowledge of the system, and experience. The appointed responsible person could be one, or a combination of:

  • yourself
  • one or more workers
  • someone from outside your business

If there are several people responsible for managing risks, e.g. because of shift-work patterns, you must make sure that everyone knows what they are responsible for and how they fit into the overall risk management of the system.

If you decide to employ Sherpa Environmental to carry out legionella risk assessments or other water treatment work, it is still the responsibility of the competent person to ensure that the treatment is carried out to the required standards. Remember, before you employ Sherpa or another legionella risk assessment contractor, you should be satisfied that they can do the work you want to the standard that you require. There are a number of external schemes to help you with this, for example on our certificates page you may find Sherpa Environmental membership documents from the Legionella Control Association and Sherpas commitment to the Code of Conduct.

Preventing The Risk From Legionella Bacteria Using A Legionella Risk Assessment

You should first consider whether you can prevent the risk of legionella bacteria by looking at the type of water system you need, e.g. identify whether it is possible to replace a wet cooling tower with a dry air-cooled system. The key point is to design, maintain and operate your water services under conditions that prevent or adequately control the growth and multiplication of legionella bacteria.

If you identify a risk that you are unable to prevent, you must introduce a course of action ie a written control scheme, that will help you to manage the risk from legionella by implementing effective control measures, by describing:

  • your system, e.g. develop a schematic diagram
  • who is responsible for carrying out the assessment and managing its implementation
  • the safe and correct operation of your system
  • what control methods and other precautions you will be using
  • what checks will be carried out, and how often will they be carried out, to ensure the controls remain effective

You should:

  • ensure that the release of water spray is properly controlled
  • avoid water temperatures and conditions that favour the growth of legionella and other micro-organisms
  • ensure water cannot stagnate anywhere in the system by keeping pipe lengths as short as possible or removing redundant pipework
  • avoid materials that encourage the growth of legionella (The Water Fittings & Materials Directory link to external website references fittings, materials, and appliances approved for use on the UK Water Supply System by the Water Regulations Advisory Scheme)
  • keep the system and the water in it clean
  • treat water to either control the growth of legionella (and other microorganisms) or limit their ability to grow
  • monitor any control measures applied
  • keep records of these and other actions taken, such as maintenance or repair work

Keeping Records

If you have five or more employees you have to record any significant findings, including those identified as being particularly at risk and the steps taken to prevent or control risks. If you have less than five employees, you do not need to write anything down, although it is useful to keep a written record of what you have done.

Records should include details of the:

  • person or persons responsible for conducting the risk assessment, managing, and implementing the written scheme
  • significant findings of the risk assessment
  • written control scheme and details of its implementation
  • details of the state of operation of the system, i.e. in use/not in use
  • results of any monitoring inspection, test or check carried out, and the dates

These records should be retained throughout the period for which they remain current and for at least two years after that period.

Other Legionella Duties

In addition, under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR), you must report any cases of legionellosis in an employee who has worked on cooling towers or hot and cold water systems that are likely to be contaminated with legionella.

Specific Legionella Risk Systems

You will also need to consider technical and further information on the following risk systems:

  • Evaporative cooling systems
  • Hot and cold water systems
  • Spa pools
  • Other risk systems

Legionella Facts – Did you know?

Legionella bacteria was first discovered after an outbreak in 1976 among people who went to a Philadelphia convention of the American Legion. Those who were affected suffered from a type of pneumonia (lung infection) that eventually became known as Legionnaires’ disease.
