Summary:

Under the Health and Safety at Work Act 1974, all managers of buildings are mandated to carry out Legionella Risk Assessments (LRAs). A building manager has a duty of care towards those living in their buildings; anyone performing an LRA must have access to both administrative as well as inspection capabilities. Hiring a professional water hygienist ensures you comply with Legionnaire's disease prevention guidelines while also providing practical advice on how to decrease the risk of one of your occupants getting this life-threatening condition. The primary source for most cases of Legionnaires' Disease is the legionella pneumophila bacterium, though it may also be brought about by similar strains of bacteria. This type of pneumonia is life-threatening—especially among older or very sick people, such as those who smoke or suffer from lung conditions.   In order to ensure the safety of building occupants, it is essential you ensure an LRA is undertaken.

Although Legionella is present in nature, it mainly lives in waters and outbreaks occur from water systems found in buildings such as cooling towers, evaporative condensers, hot and cold water storage tanks, shower heads, and whirlpool spas; provided the temperatures are at 20-46°C (68-116°F).

The bacteria multiplies due to the presence of rust, sludge, natural organic matter or other sources of nutrients. Humans are at the most risk when the contaminated droplets can be widely dispersed - this typically occurs via inhalation.

Duty holders have a responsibility to identify and assess risks posed by working activities and building water systems; they also must make sure that these risks are suitably managed through proper maintenance.

What promotes the growth of Legionella bacteria?

  1. The growth of Legionella bacteria is promoted by temperatures between 20-45°C (77°F–113°F) and the presence of a ready source of nutrients (sludge, organic matter, algae, scale, rust, etc.).
  2. Bio-film on water surfaces can also contribute to the growth of these bacteria.
  3. Poor water management and lack of training and awareness programmes can also lead to the growth of Legionella bacteria.

What external factors can help Legionella bacteria grow?

  • Water stagnation
  • Water temperature
  • Changes in municipal water quality
  • Water temperature fluctuations
  • Scale and sediment
  • pH fluctuations
  • Inadequate levels of disinfectant
  • Construction
A Legionella Risk Assessment will include reviewing your current records and a check of your previous record to ensure that all recommendations for remedial work or maintenance have been acted upon. There should be a physical inspection and consultation with everyone involved in controlling the bacteria, including the verification of management procedures and paperwork. The first part of the LRA will include reviewing your current records and previous records to ensure all recommendations have been acted upon. The second part of the assessment will involve a tour of the site to identify potential sources of Legionella contamination. A report will be prepared based on these findings, including any recommendations for actions that should be carried out to lessen the Legionella risk. Our qualified and experienced surveyors can provide you with an LRA wherever you are based in the UK.

Why do I need a Legionella Risk Assessment?

Is Legionella Risk Assessment a legal requirement

The formal system of legionella control in the UK now comprises the HSE's ACOP L8 (4th edition) and HSG274 which is split into three parts:

  • Part 1 – cooling water systems
  • Part 2 – hot and cold water systems
  • Part 3 – other risk systems
Duty holders (building owners, landlords and employers) have a responsibility to evaluate potential risk situations and take whatever steps are necessary prevent or minimise the risk from exposure to legionella. Management driven and supported with detailed paperwork to be kept for at least five years. A Legionella Risk Assessment is a legal requirement.

How often do I need a Legionella Risk Assessment?

ACOP L8 regulations suggest that the legionnaires’ risk assessment should be reviewed regularly.
The guidance used to advise that an LRA should be carried out every 2 years, however, they now suggest the risk assessment should be regularly reviewed to ensure it remains up to date.
