Legionella is a naturally occurring genus of pathogenic bacteria found in water systems that can cause potentially fatal infections if it is not quickly and effectively controlled and managed. It is a legal requirement to demonstrate that risks are under control and also follow the monitoring guidelines outlined in ACoP L8.
As members of the Legionella Control Association, NDC are qualified to advise and assist your organisation in controlling the risk of Legionellosis. We take a practical ‘hands on’ approach backed up by many years of experience in both large and small organisations. Our trained, competent Staff have a wealth of experience to advise clients on the risks associated with all water systems including: wet air conditioning systems, evaporative cooling towers and new installations.
Legionella sp. is a naturally occurring hazard that flourishes in water systems. Controlling the risk of contracting Legionnaires Disease or Pontiac Fever from domestic and industrial water systems is a legal requirement. The HSE are regularly contacted about outbreaks and systems that have potentially failed to comply with these regulations.
The Health and Safety Commission’s (HSE) document ACoP L8, “Legionnaires’ disease: The control of legionella bacteria in water systems”, includes practical advice on the requirements of “The Health and Safety at Work Act 1974” (HSWA) and the “Control of Substances Hazardous to Health Regulations 1999” (COSHH), plus guidance on compliance with the relevant parts of the “Management of Health and Safety at Work Regulations 1999” (MHSWR).
Requirements and Responsibility
The legislation requires that employers and those responsible for water systems in non-domestic buildings have in place the following key requirements:
- Identify and assess sources of risk
- Prepare a written scheme detailing precautions
- Implement, monitor and manage precautions
- Keep detailed records or a log book of the precautions
- Appoint a trained responsible person to manage the above and ensure that the risk is controlled
In addition, there is a requirement to have a Legionella Risk Assessment on a periodic basis and if there is reason to suspect that is no longer valid, for example:
- Where there have been changes to the plant
- Where the users of a building have changed, e.g. neutropenic patients, new born babies etc…
- Where there have been changes to the use of the building
- Where new information about risk or control measures has become available
- Where monitoring indicates that control measures are no longer effective
