Legionella Risk Assessment

Risk Assessments for the Healthcare Sector

Water safety planning is an essential consideration for any healthcare environment. Hospitals, care homes and medical centres have a responsibility to maintain safe and compliant water systems, particularly where patients and service users may be more vulnerable to waterborne pathogens.

At 4i Water Services, we provide specialist healthcare Legionella risk assessment services for private healthcare providers and NHS organisations. Our experienced team supports hospitals, care homes and medical centres with water safety planning, compliance and risk management across complex healthcare water systems.

One of the most important aspects of healthcare water safety is the assessment and management of risks associated with Legionella, Pseudomonas aeruginosa and other waterborne pathogens.

Know What’s Required

A Legionella risk assessment is a legal requirement and forms a fundamental part of an effective water safety plan. Assessments should be reviewed regularly and remain up to date to ensure ongoing compliance and effective risk management.

Healthcare Legionella risk assessments must be undertaken by suitably qualified personnel with a thorough understanding of the relevant guidance and standards, including:

  • HTM04-01
  • ACoP L8
  • HSG274 Part 2
  • BS 8580
  • BSRIA FMS 4/99
  • BSRIA BG 57/2015

Our healthcare risk assessments evaluate all areas of potential risk relating to Legionella, Pseudomonas aeruginosa and other relevant pathogens, as well as risks associated with water storage, maintenance and day-to-day operation.

How Can 4i Water Services Help?

Our healthcare Legionella risk assessment services support both private healthcare and NHS water treatment programmes by identifying potential hazards, prioritising corrective actions and implementing effective control measures that protect patients, staff and visitors.

A full healthcare Legionella risk assessment can include:

Current in-house policies and procedures
Team governance and accountability
Team education and training
Safe access to equipment
Prevention of unauthorised access to equipment
Scalding risks and the appropriate installation of TMVs
Failure to maintain necessary hot and cold system supply temperatures.
Infrequently used outlets
The unnecessary use of flexible hoses and any containing inappropriate lining materials
Sampling, monitoring and testing programmes that needs to be put in place
Backflow protection
Clinical practice where water may come into contact with patients and their invasive devices
The appropriate cleaning of the environment and equipment
The disposal of blood, body fluids and patients’ wash-water
The maintenance and cleaning of wash-hand basins and associated taps, specialist baths and other water outlets
Suitable sitting and installation of wash-hand basics including the appropriate positioning of soap and antimicrobial hand-rub dispensers
Other devices that increase/decrease the temperature of water (for example, ice-making machines, water chillers) which may not be appropriate where patients are at particular risk such as in augmented care settings.
Engineering assessment of water systems, including appropriate design, installation, commissioning, maintenance and verification of the effectiveness of control measures.

Once hazards and hazardous events have been identified, risks can be assessed based on their likelihood and potential impact. This allows healthcare providers to prioritise risk management activities and implement practical improvements that support compliance, patient safety and wider private healthcare and NHS water treatment objectives.

By taking a proactive approach to healthcare water safety and Legionella management, healthcare organisations can protect vulnerable patients, improve operational resilience and maintain safe, compliant and efficient water systems.

With this information, you will have sight of the best way forwards to make sure your healthcare building and water systems are safe, and your team’s training is up to date. Don’t just meet compliance today – with the insights from your assessment, you can also safeguard for the future.
