Legionella Risk Assessments

Our Legionella Risk Assessment Services:

We have been assisting our clients by carrying out Legionella Risk Assessments to their workforce, customers and buildings for more than 15 years.

Waterman Compliance Services can help you to assess and manage these risks and ensure that you comply with all legal requirements.

Waterman are a Legionella Control Association registered company providing national coverage.

In order to comply with the Health and Safety Commission Approved Code of Practice L8 (Fourth edition) & HSG274 (Legionnaires’ Disease, The control of Legionella bacteria in water systems) in the UK and HPSC National Guidelines for the Control of Legionellosis in Ireland 2009, companies are under a legal obligation to minimise and control the risk of Legionella by:

  • Identifying and assessing the sources of risk of exposure
  • Implementing and managing precautions
  • Appointing a person to be responsible
  • Recording all related actions

All Waterman Legionella Risk Assessments are completed by City and Guilds qualified, competent and experienced professional specialists in accordance with British Standard BS 8580-1:2019 Water quality – Risk assessments for Legionella control.

As part of the assessment, our specialists will recommend precautionary measures to reduce the overall risk. These may include management responsibility and training, as well as system maintenance, refurbishment and routine monitoring and inspection.

We understand the increasing pressure on budgets. With this in mind all our recommendations are prioritised, HIGH – MEDIUM – LOW which means that money spent on high priority actions will produce the maximum benefit in terms of risk reduction.

Waterman utilise a European standard matrix which provides an actual calculation rather than an individual’s personal opinion which can fluctuate and differ between assessors.

Risk Rating is calculated by multiplying the likelihood against the consequences, e.g. taking a likelihood of 2, which is classified as probable risk and multiplying this against a consequence of 2, which is classified as a minor risk this would give you an overall risk rating of 4.

History of Legionellosis, including Legionnairs’ Disease:

Legionellosis is a collective term for diseases caused by legionella bacteria including the most serious Legionnaires’ disease, as well as the similar but less serious conditions of Pontiac fever and Lochgoilhead fever. Legionnaires’ disease is a potentially fatal form of pneumonia and everyone is susceptible to infection. The risk increases with age but some people are at higher risk including:

  • people over 45 years of age
  • smokers and heavy drinkers
  • people suffering from chronic respiratory or kidney disease
  • diabetes, lung and heart disease
  • anyone with an impaired immune system

The bacterium Legionella pneumophila and related bacteria are common in natural water sources such as rivers, lakes and reservoirs, but usually in low numbers. They may also be found in purpose-built water systems such as cooling towers, evaporative condensers, hot and cold water systems and spa pools.

If conditions are favourable, the bacteria may grow increasing the risks of Legionnaires’ disease and it is therefore important to control the risks by introducing appropriate measures outlined in Legionnaires’ disease – The control of legionella bacteria in water systems – L8 (Fourth edition) for UK and Health Protection Surveillance Centre (HPSC) – National Guidelines for the Control of Legionellosis in Ireland 2009 for Ireland.
