The latest version of the British Standard for Legionella Risk Assessments BS8580-1:2019 was released earlier this year, superseding the previous 2010 version. Eastwood Park water hygiene trainer and expert Mike Quest highlights the key changes.
With over 25 years in the water industry, Mike brings vast experience and in-depth knowledge to our water hygiene courses. Recent experience includes 5 years as a committee member of the Legionella Control Association (and he is now one of their Company Auditors), as a Senior Member of the Water Management Society and as a Member of IHEEM. He has also given technical papers at numerous events across the UK.

The new standard gives greater emphasis on the requirement for risk assessors to have experience, specialist knowledge and understanding of risks and controls, and provide evidence that appropriate training in the type and complexity of the system they are assessing has taken place.
The standard has also introduced the concept of carrying out risk assessments internally and the need for impartiality, especially with respect to factors such as the cost of remediation.
The word “scoring” has been replaced by “rating” and raises caution about using complex algorithms and scoring systems due to their potential to mask important issues, with emphasis on clear explanation of the rating systems to the intended reader.
There have been no significant changes to the requirement, but there is a greater emphasis on keeping the report concise and simple to read, avoiding jargon and unexplained abbreviations!
The review cycle for risk assessments has been reiterated and requires the risk assessor to make it clear under which circumstances a review is necessary.
Perhaps the greatest change in content has taken place in the informative annexes, much of which reflects the developments in legionella control with all risk systems as contained in HSG274 parts 1, 2 & 3, plus the latest guidance on spa pools laid out in HSG282 (2017).
- The risk assessment requirements for Hot & Cold Water Systems has seen significant change
- Annex C: Open Evaporative Cooling Systems and Annex D: Spa Pools have been entirely rewritten
- Annex C: Open Evaporative Cooling Systems includes a name change to ensure all systems that operate in “wet mode”, including adiabatic systems, are included.
- Annex D: Spa Pools is now much clearer and avoids differentiating hot tubs from spa pools in commercial situations.
- Annex F: Example Spa Pool Checklist has now been removed entirely.
- Annex H: Schematic drawings (previously Annex G) is largely unchanged, although examples of schematic drawings are included for information.
Eastwood Park's water hygiene training covers the most relevant and up to date guidance, catering for healthcare and non-healthcare staff, including (but not limited to) Technicians, Appointed Responsible Persons, those responsible for the control of Legionella and those responsible for managing, maintaining and monitoring hot & cold water systems.
