Unmasking the Invisible Enemy: Legionella Management – Your Shield Against a Silent Killer

Legionella Management

Did you know that your simple-looking water system can house a deadly bacteria known as Legionella?

Its management isn’t just a good-to-know; it’s an absolute must. In this post, we aim to equip you with all the necessary knowledge about Legionella management, an often overlooked but crucial aspect of safety services.

Understanding Legionella

What is Legionella and what diseases can it cause?

Legionella is a type of bacteria found naturally in freshwater environments, like lakes and streams. However, it can become a health concern when it starts to grow in human-made water systems such as hot tubs, cooling towers, and large plumbing systems.

It causes a type of pneumonia known as Legionnaires’ disease and a milder illness known as Pontiac fever. These diseases are together known as Legionellosis and can be fatal if not promptly treated.

What conditions promote the growth of Legionella bacteria?

Legionella thrives in warm, stagnant water between 20°C and 45°C, particularly if the water is rusty, slimy, or contains a lot of sediment. The bacteria multiply and become dangerous when water is aerosolized, i.e., transformed into tiny droplets that people can inhale.

Legionella Risks

What are the risks associated with Legionella?

Legionella poses a significant health risk, primarily through inhalation of contaminated aerosols. Legionnaires’ disease is a severe form of pneumonia, causing cough, shortness of breath, fever, muscle aches, and headaches. In contrast, Pontiac fever is a milder infection with flu-like symptoms.

Where can Legionella bacteria grow and what factors can help it grow?

Human-made water systems often provide favourable conditions for Legionella to grow. It can flourish in cooling towers, hot tubs, hot water tanks, large plumbing systems, and decorative fountains. Factors that help its growth include stagnant water, optimal temperature, sediment that can provide nutrients, and lack of disinfectants.

Legionella Management and Control

What are the primary methods used to control the risk from Legionella?

Effective Legionella management hinges on regular inspection, maintenance, and cleaning of water systems, temperature control, and the use of biocides. The strategy involves breaking the cycle of conditions that allow the bacteria to grow and become a risk.

What is the role of a competent person in Legionella management?

A ‘competent person’, often known as the ‘responsible person’, plays a crucial role in Legionella management. This person should have the knowledge, skills, and experience necessary to oversee the control scheme and ensure that all tasks are carried out to a satisfactory standard.

Why are regular checks, inspections, and cleaning of the system important to Legionella management?

Regular checks, inspections, and cleaning prevent conditions that promote Legionella growth. Regularly flushing out systems, avoiding water stagnation, and maintaining the right temperature can significantly reduce the risk of an outbreak.

Legionella Regulations in the UK

What are the key legislations relating to Legionella management in the UK?

In the UK, the primary regulations concerning Legionella management include the Health and Safety at Work Act 1974 and the Control of Substances Hazardous to Health Regulations 2002 (COSHH). Both require employers to ensure the safety and health of their employees and others who may be affected by their work activities.

Why is a Legionella risk assessment needed and what does it involve?

A Legionella risk assessment identifies and assesses potential sources of Legionella exposure. It involves assessing the risk, implementing and managing precautions, checking control measures, keeping records, and appointing a competent person responsible for managing controls.

Legionella Risk Assessment

When and why should a Legionella Risk Assessment be conducted?

Legionella Risk Assessment should be conducted regularly – ideally annually or whenever significant changes occur to the water system or its use. It ensures Legionella risks are effectively identified and controlled, safeguarding the health of those on the premises.

What should you expect from a Legionella risk assessment?

A Legionella risk assessment includes a thorough site survey, assessment of water systems, identification of potential risk areas, recommendations for risk management, a comprehensive report, and a review of existing Legionella control measures.
