Managing the control of Legionella

The control of Legionella can be challenging at the beginning, but help is always available.  Make sure you choose your specialist contractor wisely, use the LCA directory to see if the contractor is registered with the LCA and also registered to undertake the task you require. Franks Portlock have the expertise and experience to advise you in all aspects below, to ensure you are fully compliant with the current legislation and guidelines.

Legionella Monitoring to meet HSE Guidelines 

Once you have your Legionella Risk Assessment completed, and signed off all the actions recommended within it, you now must monitor and maintain your water systems to ensure the remedial works you have carried out remain effective.

The HSE provides excellent documentation on monitoring legionella bacteria in hot and cold-water systems. This is the basis for any legionella control scheme, and we will recommend the contents as a minimum. 

A legionella control scheme will typically include the following:

  • A Legionella Risk assessment. 
  • The specific role of an appointed competent person, known as the ‘responsible person’. 
  • The control schemes. 
  • Review of control measures.
  • Duties and responsibilities of those involved in the supply of water systems.

Franks Portlock can assist you in all the above, including the design and implementation of a control scheme in line with the current guidelines produced by the HSE.

What is a Legionella written scheme?

If your assessment has shown that there is a reasonably foreseeable risk of exposure to legionella bacteria, there needs to be a written scheme in place to control that risk.

A Legionella written scheme of control is a comprehensive risk management document, identifying the necessary measures needed to control the risks from exposure to Legionella bacteria. 

The written scheme is separate to the legionella risk assessment and is a legal requirement identified by the Health & Safety Executive in their Approved Code of Practice and guidance ACOP L8:2013 (forth addition) “Legionnaires’ disease. The control of legionella bacteria in water systems”.

The written scheme must include an up-to-date plan of the system, instructions for the operation of the system, precautions to be taken to control the risk of exposure to legionella bacteria and details of the checks that are to be carried out (and their frequency) to ensure that the scheme is effective.

How do you control Legionella in water?

Temperature is the easiest and cheapest method of controlling the bacteria and temperature profiling is still, in most cases, the chosen method of control. Temperature is a proven form of control; however, it does come with its own issues, normally with storing the hot water at 60ׄ°C and distributing at >50°C.

Who is responsible for monitoring the risk of legionella?

If the risk assessment shows that there is a reasonably foreseeable risk and it is reasonably practicable to prevent exposure or control the risk from  exposure, the duty holder should appoint a competent person or persons to help undertake the measures needed to comply with  the requirements in COSHH. The appointed competent person or persons should have sufficient authority, competence and knowledge of the installation to ensure that all operational procedures are carried out in a timely and effective manner.

How do I meet Legionella Compliance?

Legionella Risk Assessment: The first step to meet Legionella compliance is to undertake a full legionella risk assessment. This risk assessment will identify any potential risk from Legionella that derives from your water system. 

Legionella Remedial Works:  Your next step is once the risk assessment has been carried out, and the risks have been identified, they must be removed or at the very least – managed in order to go forward with the project. This would be classed as carrying out Legionella remedial works. 

Legionella Monitoring: You must control and manage the ongoing risk of Legionella exposure to your employees and visitors from your water system by carrying out consistent Legionella monitoring to ensure that your water system continues to be safe.
