Legionella Testing to L8 Standards

Legionella testing must be carried out by a professional to identify any possible conditions that encourage proliferation and a Legionella Risk Assessment may be required. As certified members of the Legionella Control Association, Swiftclean are fully qualified to carry out legionella testing, risk assessments and advise on compliance to L8 standards.

What is ACoP L8?

The Legionnaires’ disease Approved Code of Practice (ACoP) L8 is aimed at dutyholders, including employers, those in control of premises and those with health and safety responsibilities for others. The code of practice has been put into place to help businesses comply with their legal duties in relation to Legionella.

It’s imperative that every employer has a duty of care to ensure an employee’s health, safety and welfare. This specifically includes controlling the risks of hazardous substances, including Legionella bacteria.

What is Legionella?

Legionnaires disease is a severe form of pneumonia, which causes potentially fatal complications to occur within the human lungs. The disease is not contagious; it is contracted when bacteria, in the form of tiny contaminated water droplets or aerosols, is inhaled into the lungs.

Where Can the Legionella Bacteria Be Found?

Legionella bacteria is found to be present in up to 13% of water samples and it is common to find harmless levels of legionella and other bacteria in mains supplied drinking water.

For this reason, it is recommended that you do not use a legionella testing kit, as the samples should be taken from specific high risk areas (such as low temperatures in hot water systems, healthcare facilities etc).

It is recommended to test for Legionella when:

  • A water system is being treated with biocides and hot water is stored or distributed at lower temperatures.
  • The limits of a control regime, e.g. temperature or disinfectant concentrations, are not being consistently achieved.
  • There is a high-risk area or a place where there is a population with increased susceptibility, e.g. in healthcare premises such as care homes.
  • A water system is suspected or identified in a case of an outbreak of legionellosis.

How Can You Control the Risk of Legionella?

Water temperature controls

The risk of Legionella can be controlled by implicating stringent water temperature controls.

Water services should be operated at temperatures that prevent Legionella growth, such as:

  • Hot water storage cylinders should store water at 60°C or higher
  • Hot water should be distributed at 50°C or higher
  • Cold water should be stored and distributed below 20°C

Design systems to minimise Legionella growth

Legionella growth can occur in stagnant water, so to reduce to the risk of this you should remove any dead ends of pipe work, flush out any frequently used outlets weekly and clean and descale any water outlets at least quarterly.

Cold-water storage tanks should also be cleaned regularly, and water drained from hot water cylinders to check for debris or signs of corrosion.

Additional controls

Other methods to control Legionella should include the analysis of water samples periodically to demonstrate that bacteria counts are acceptable. The frequency of the water samples should be determined by the level of risk, in accordance with the risk assessment.

FAQ’s

How do you test for Legionella in water?

Thorough Legionella testing will take place by taking samples from high risk areas, such as low temperatures in hot water systems, healthcare facilities etc.

How often should you test for Legionella?

The previous industry guidance suggested that a legionella risk assessment should be reviewed at least every two years, but now it states that a risk assessment should be a living document which must be reviewed regularly to ensure it remains up to date.

How do you control the risk of Legionella?

In order to control and reduce the risk of Legionella, we recommend that all water temperature controlled units should be checked. Water services should also operate at temperatures that prevent the growth of Legionella, such as:

  • Hot water storage cylinders should store water at 60°C or higher
  • Hot water should be distributed at 50°C or higher
  • Cold water should be stored and distributed below 20°C
