The temporary closure of Hazeley Academy in Milton Keynes due to Legionella detection has highlighted a critical health and safety concern facing educational institutions.
But what exactly is Legionella, and why should schools be particularly vigilant? We speak to Kieran Irving, who recently rejoined Lucion as Legionella and Water Treatment Manager.
Understanding Legionella Risk
“Legionella is a naturally occurring bacteria found in water systems, but it becomes dangerous when it multiplies in conditions typically found in building water systems,” explains Kieran. “When people inhale tiny water droplets containing the bacteria, they can develop Legionnaires’ disease – a serious form of pneumonia that can be particularly dangerous for vulnerable individuals.”
The bacteria thrives in temperatures between 20°C and 45°C, finding perfect breeding grounds in:
- Stagnant water
- Systems with optimal growth temperatures
- Areas with sediment or scale build-up
- Poorly maintained water systems
Why Schools Are at Higher Risk of Legionella
“Schools present unique challenges for water management,” says Irving, drawing from his 12 years of industry experience. “The combination of complex water systems, varying usage patterns throughout the academic year, and the presence of both young and adult occupants creates a perfect storm of risk factors.”
Extended holiday periods, particularly summer breaks, can lead to water stagnation in pipes and storage tanks.
Many schools also operate across multiple buildings of different ages, each with their own water systems, creating a complex network that requires careful management. Add to this the diverse water needs – from drinking fountains and washrooms to science labs and swimming pools – and the challenge becomes clear.
Legionella Legal Responsibilities
Schools operate under strict legal obligations when it comes to water safety management.
Under the Health and Safety at Work Act 1974 and Control of Substances Hazardous to Health (COSHH) Regulations 2002, educational institutions must take proactive steps to protect their occupants from water-related health risks.
This means conducting regular risk assessments, implementing appropriate control measures, and maintaining detailed records of all actions taken. Schools must also ensure that staff members involved in water management receive appropriate training and understand their responsibilities in maintaining safe water systems.
Practical Legionella Prevention Strategies
“Prevention is about understanding and controlling the conditions that allow Legionella to thrive,” Irving explains.
An effective legionella prevention strategy focuses on temperature management – keeping cold water below 20°C and maintaining hot water above 50°C, while taking necessary precautions against scalding risks.
Regular system maintenance is equally crucial, including cleaning and descaling of shower heads and taps, flushing infrequently used outlets, and conducting thorough tank inspections.
Holiday periods require particular attention, as Larne Fuller, Area Director at Lucion Services, points out: “Schools need specific strategies for managing water systems during extended breaks. This might involve scheduled flushing programmes, holiday sampling regimes, and careful recommissioning procedures before terms begin.”
What to do if Legionella is Detected
The Hazeley Academy case demonstrates good practice in response to Legionella detection. Upon discovering the bacteria during routine testing, the school took immediate action, closing its doors and implementing necessary control measures. This swift response highlights the importance of having clear emergency procedures in place and understanding when to take decisive action.
While the Hazeley Academy situation has raised concerns across the education sector, it also demonstrates how effective monitoring can identify issues before they lead to illness.
“What we’re seeing should serve as a catalyst for other schools to review their water safety protocols,” says Irving. “With proper management and regular attention, the risks associated with Legionella can be effectively controlled.”
The key lies in viewing water safety as an ongoing priority rather than a periodic concern. Schools that invest in comprehensive water management programmes, maintain vigilant oversight, and seek expert guidance when needed are best positioned to protect their communities from water-related health risks.
As a legionella testing and risk management provider, Lucion Services brings decades of experience in supporting primary and secondary education settings with their water safety management.
Our expertise, coupled with our commitment to protecting people and planet, enables us to help educational facilities maintain safe learning environments throughout the academic year and beyond.
