What is the appetite for risk amongst managers of education estates with responsibility for health & safety? We would expect such organisations to operate on the basis that risks to health and safety should be ‘as low as reasonably practicable’. For example, when there is a broken window, missing or broken paving slab or a blocked fire exit these obvious issues would be fixed promptly to avoid injury to pupils / students, staff and visitors.

However, when managing the Legionella risks within an educational organisation, the hazards contained within water systems are not always visible. Moreover, hazards are hidden around the building; lost behind panelling, within the building fabric, under floors, in ducts, in ceiling voids, roof spaces, behind fixtures or furniture or even in your office!

What is Legionella?

Head Teacher School EducationLegionella is a naturally occurring bacteria that lives within water. When favourable conditions are allowed to develop within buildings, this bacteria can proliferate and potentially colonise your domestic water system.

When water is used, i.e. through running a tap or flushing a toilet, very fine droplets of water are released, as aerosol, which can carry the bacteria in the air.

If a person breathes in this aerosol containing Legionella bacteria, they may develop legionellosis.  This is the collective term for diseases caused by Legionella bacteria, and includes amongst others, Legionnaires’ disease, Pontiac fever and Lochgoilhead fever.

Legionnaires’ disease is a potentially fatal form of pneumonia to which certain groups are more susceptible than others and, although anyone can catch Legionnaires’ disease, new-born babies, males, smokers, the over fifties, the immuno-compromised or those with underlying health issues are more at risk.

 

How can Schools, Colleges and Universities manage Legionella?

It is a requirement of the Management of Health & Safety at Work Regulations and Control of Substances Hazardous to Health Regulations that suitable & sufficient management processes, training, risk assessment and monitoring arrangements are in place for health and safety issues, of which Legionella risk management is included.

 

The Health & Safety Executive's Approved Code of Practice [ACoP] L8 and the associated HSG274 Technical Guidance are available for all, especially those identified as being responsible for the management of Legionella.

 

We’ve prepared a five step guide for managers of educational estates and those responsible for managing Legionella risk within their organisation e.g. school, academy, college or university.

 

One: Management, Communication & Training.

Inadequate management, poor communication and insufficient Legionella training have all been identified as contributory factors to outbreaks of Legionnaires’ disease. The aforementioned ACoP L8 outlines the need to:

  • Appoint a Legionella Responsible Person; who must have sufficient authority, knowledge and competence.

  • Prepare a Written Scheme of Control / Water Safety Plan; which details management roles, responsibilities, communication pathways, Legionella training and operational control processes for water risk systems [including design, operation, monitoring and maintenance].

Education estates managers can take early intervention when it comes to pitfalls of Legionella risk management by attending a quality training course. Legionella Training should not only list the requirements of the various legislation and guidance but also provide a practical approach as well. E.g. what does a typical water system comprise, where the potential issues can be found and why do they occur?

 

Two: Independent Water Hygiene Advice.

The Management of Health and Safety at Work Regulations state that organisations should have ‘access to competent health & safety advice’. If the required subject knowledge and/or level of competence does not exist within the organisation, then duty holders may seek to employ a specialist adviser to contribute towards overall health & safety management.

 

These ‘expert specialist advisors’ must demonstrate their own competency and knowledge and be able to demonstrate impartiality, integrity and sound reasoning, with evidence, for any proposed course of action or advise given. To help demonstrate impartiality, this expert specialist advisor could be an Authorising Engineer [Water], acting as an auditor to monitor effectiveness and performance of the educational organisation without the competing influence of commercial interests. The Authorising Engineer [Water] can also complete competency appraisals for those involved in the management of Legionella.

 

Examples of the consequences of taking advice from those with vested interest include a client who was advised that cold water storage tanks should be cleaned every 3 months and the upselling of unnecessary water sampling or water treatment systems.

 

Three: Legionella Risk Assessments.

The findings of the Legionella risk assessment will underpin and define the Written Scheme of Control / Water Safety Plan required to manage the risk of legionella. The need for a suitable and sufficient risk assessment remains absolute in order to support the development of an effective Written Scheme of Control.

 

It's therefore vitally important to choose your Legionella risk assessment provider carefully. The HSE’s ACoP L8 highlights membership of the Legionella Control Association as suitable pre-selection criteria –  and of which there are over 300 members nationally. A further degree of reassurance can be gained by looking at UKAS accredited risk assessment providers, currently UKAS lists only a handful of companies nationally that are accredited.

 

Choosing your risk assessment provider wisely can save money, time and effort through potentially ‘hidden’ savings i.e. elimination of inappropriate actions and reduce unnecessary remedial work from those suppliers who have a vested interest.

 

In our previous blogs we have discussed what a Legionella risk assessment should include and what makes a good risk assessor.

 

Four: Written Scheme of Control / Water Safety Plan.

Formulate a plan for water safety management (aka Written Scheme / Water Safety Plan) that includes:

  • Policy statement including scope and purpose;

  • Details of roles, responsibilities & communication pathways for those involved;

  • Process for ensuring training and competency;

  • Legionella Risk assessment and risk assessment review;

  • Description of the control strategy for safe operation of the water systems;

  • Procedures for carrying out the control strategy;

  • Procedures for monitoring the effectiveness of the control strategy;

  • Contingency procedures for foreseeable eventualities of concern, for example where monitoring shows that the control strategy has not been consistently applied or that it is ineffective;

  • Review process for reviewing the effectiveness of the control measures and management arrangements;

  • Details of the documentation and water safety records to be maintained.

 

As an example, it may be helpful to consider the requirement for a ‘description of the control strategy for safe operation of the water systems’. What happens to the water system in the buildings during breaks in study i.e. Summer, Christmas or Easter holidays? Whilst some buildings may remain operational throughout the year but others may be vacant or only partially occupied, and if so, how are they managed?

 

A well thought out Written Scheme of Control is the guide to successful water safety management for the educational organisation.

 

Five: Water Hygiene Audit.

Our final step, is the Water Hygiene Audit, a key element in any successful management framework! That said, auditing is very often-overlooked; perhaps due to budget constraints and the difficulty in assigning value to the process of an audit? However, in steps 2 and 4 we’ve alluded to auditing in the need for ‘reviewing the effectiveness of the management arrangements and control measures in place’.

An audit completed regularly can provide the assurance that Legionella matters remain in hand and also identify opportunities for improving effectiveness or efficiency.

Indeed, the audit closes the loop between what we have in place and the goals we set out to achieve.
