Legionella risk assessments: a crucial part of facilities management

In the world of facilities management, health and safety compliance is non-negotiable. Among the many responsibilities faced by building managers and duty holders, managing the risk of Legionella bacteria is one that cannot be overlooked.

Legionella is a potentially deadly bacteria found in natural water sources but can also proliferate in man-made water systems such as cooling towers, hot and cold-water systems, and decorative fountains. If inhaled through water droplets, it can lead to Legionnaires’ disease – a severe form of pneumonia that can be fatal, particularly in vulnerable individuals.

For facilities managers, ensuring regular Legionella risk assessments are carried out is not only a legal obligation under the Health and Safety at Work Act 1974 and COSHH regulations, but it’s also vital to maintaining a safe environment for building occupants and staff.

What is a Legionella risk assessment?

A Legionella risk assessment is a thorough review of your building’s water systems, identifying potential areas where the bacteria could grow and spread. It includes:

• Inspection of all water systems and associated equipment
• Assessment of water temperature control measures
• Evaluation of system design and usage
• Identification of risk factors such as stagnant water or scale build-up
• Recommendations for control measures, monitoring, and maintenance

The outcome of the assessment should be a detailed report outlining any risks found and a clear action plan to mitigate them.

Why it matters for Facilities Management

Facilities management is about ensuring that buildings operate efficiently, safely, and compliantly. Legionella risk assessments sit at the core of this, helping:

• Protect health and safety: preventing Legionnaires’ disease is a moral and legal responsibility.
• Avoid costly downtime: an outbreak can lead to building closures, disruption, and reputational damage.
• Stay compliant: regular assessments and record-keeping.
• Enhance system efficiency: properly managed water systems perform better and last longer.

Whether you’re managing a hospital, school, office block or industrial site, water systems can vary in complexity – but all pose potential risk if not correctly maintained. That’s why having a competent, experienced partner is crucial.
