When to review or update your legionella risk assessment
The UK’s Health & Safety Executive, in their Approved Code of Practice ACOP L8 which deals with Legionnaires’ disease and the control of Legionella bacteria, cover this issue but don’t give a specific frequency for the risk assessment review. However, they make it clear that it is important to periodically review its accuracy just in case things change.
Changes that may require a review of the assessment
The HSE recommend that the legionella assessment be used as a working document, they actually refer to it as a "living document”, meaning that it should be reviewed regularly, especially when it is suspected that the assessment may no longer be valid. Situations where this may occur include:
- When there are changes to the water system or how it is used
- When there are changes to the use of the building
- When new legionella risk management techniques or control measures become available
- If the test results for the facility indicate the current control measures are not effective
- When there are changes to key personnel – Duty Holder, Responsible Person etc.
- When the water system is identified in a case of Legionnaires’ disease
While there is no specified frequency for the review of a legionella risk assessment, in practice we would typically recommend that it be reviewed at least every two years or sooner if any of the conditions listed above occur.
