How often should legionella testing take place?

by | Nov 9, 2018 | Blog

The Health & Safety Executive’s (HSE) Approved Code of Practice L8 regulations say that employers are required “to review the assessment regularly and specifically when there is a reason to believe that the original risk assessment may no longer be valid”.

In the past, the HSE guidelines were to have a legionella risk assessment at least every two years, but now there is no longer a timeframe. However, our advice is to conduct legionella review annually as the guidelines indicates to ensure legionella risk is minimised.

 

What are the responsibilities of a legionella risk assessor?

 

Under the Health and Safety at Work etc Act 1974 (HSWA) and Management of Health and Safety at Work Regulations (MHSWR) state that if you are the person in control of a premises, or an employer, you are responsible for taking the correct precautions that will reduce the risks of exposure to legionella. This includes:

  • identifying and assessing sources of risk
  • managing any risks
  • preventing or controlling risks
  • keeping and maintaining correct records

 

When to do an exceptional legionella risk assessment

 

There are circumstances under which it would be advisable to do an additional legionella  risk assessment, for example:

  • Any changes to the water system
  • Changes in key personnel
  • If there is a case of legionnaires disease
  • Whenever there is a change in HSE advice or new information about legionella risks

For more detailed information, check out the Health & Safety Executive’s Approved Code of Practice, Legionnaires’ disease: The control of Legionella bacteria in water systems (L8), that contains guidance on how to manage and control the risks in your system.
