Legionnaires Disease Risk Assessment Services
Much has been learnt about Legionnaires’ disease and about the control of Legionellosis yet outbreaks still occur. NIFES specialises in providing accurate and concise Legionella risk assessments for a range of clients across all industries. Following assessment, we can then also provide the services required to prevent Legionnaires disease outbreaks.
What is Legionella?
Legionnaires’ disease is a type of pneumonia. It is an uncommon but serious disease.
The bacterium which causes Legionnaires’ disease is widespread in nature. It mainly lives in water e.g. ponds where it does not usually cause problems.
Outbreaks occur from purpose-built water systems where temperatures are warm enough to encourage growth of the bacteria, e.g. in cooling towers, evaporative condensers, whirlpool spas and from water used for domestic purposes in buildings such as hotels.
To comply with ACOP L8, companies have a legal obligation to minimise the risk of legionellosis outbreaks by:
- Identifying the sources of risk and exposure to legionella bacteria through thorough and regular risk assessments;
- Implementing precautionary measures designed to fix any problems identified via the risk assessment and ensure legionella control;
- Keeping records of all actions related to legionella assessments, periodic legionella control measures, and any remedial works to water systems;
- Appointing a designated person to be managerially responsible for the above.

Legionella Control: What is involved
If you’re responsible for the control, there is detailed site work which is necessary to determine water system conditions and to identify risks.
Our objectives are simple; to review and assess the risk in order to meet with the L8
code of practice and guidance. The results of this site work are produced in risk assessments, costed recommendations and up-dated drawings.
As part of our detailed outputs, we will provide a schematic drawing and photos (as is reasonably practicable).
NIFES provide a strategic and practical approach to health and safety management, covering both short and long term objectives. We analyse information from physical surveys and existing data to produce health and safety audits, risk assessment reviews, training needs analyses and compliance gap analyses.
Legionella bacteria require a supply of nutrients to multiply. Sources include algae, amoebae and other bacteria. The presence of sediment, sludge, scale and other material within water systems, together with biofilms, are also thought to play an important role in harbouring and providing favourable conditions in which the legionella bacteria may grow.
Legionella Control: Advice & Guidance
Following risk assessment, NIFES consultants can also provide ongoing support and guidance to help you in all aspects of Legionnaires disease risk prevention, L8 compliance and Legionella Control.
This can come in the form of comprehensive Legionella awareness, control and management training; regular water hygiene and testing services; and disinfection and cleaning services.
Queen Elizabeth Hospital Kings Lynn NHS Foundation Trust – Legionella Control Gap Analysis
Queen Elizabeth Hospital has many complicated and integrated water systems with fall under the required control of legislation and the Healthcare Technical Memorandums (HTMs). The hospital provides services for a wide spectrum of patients, requiring an assessment of risk and an application of control.
NIFES quantified the hospital’s systems, producing schematic drawings, risk assessments, an action plan with remedial requirements and a Written Schema of Control. Since the original assessment, NIFES carry out an annual gap analysis of the control of Legionella bacteria at the hospital, enabling ongoing management of the hospital’s water systems.
Queen Elizabeth Hospital NHS Foundation Trust now have confidence and direction in the control of Legionella bacteria.
