The ACoP L8 (Revision 4) and Technical Guidance HSG 274

29 May 2014

On 25 th November 2013, the Health and Safety Executive (HSE) published Revision 4 of the Approved Code of Practice Legionnaires’ Disease: The control of Legionella bacteria in water systems (L8)” . This was the first step in an attempt to provide updated and more detailed guidance for employers in preventing Legionnaires’ disease.

n the 7th April 2014, the HSE formally published the final part of their Technical Guidance HSG274: Part 2 The control of legionella bacteria in hot and cold water systems. This was the final part in the three part series of Technical Guidance documents on the control of legionella within water systems.

• ACoP L8 The control of legionella bacteria in water systems (Fourth Edition).
• HSG 274 Part 1: The control of legionella bacteria in evaporative cooling systems.
• HSG 274 Part 2: The control of legionella bacteria in hot and cold water systems .
• HSG 274 Part 3: The control of legionella bacteria in other risk systems.

The ACoP, along with supporting Technical Guidance, provides sound practical advice to employers on how to control the risk of legionella bacteria in water systems.

With a high fatality rate of 10% - 15% Legionnaires’ disease remains a major concern for the HSE, which considers it a preventable disease, and the control of Legionella bacteria has been a priority for both the HSE and Department of Health for many years now. Outbreaks of Legionnaires’ disease often gain headline status and over the last couple of years we have seen such outbreaks in schools, hospitals and office blocks across the country.

Employers have previously found it difficult to distinguish between requirements that have ACoP (Approved Code of Practice) status and information that is purely for guidance. The latest publications see a clearer distinction between the legal requirements and guidance, which is reflected in the introduction of the separate Technical Guidance document (HSG 274). This separation should help to provide better clarity for employers.

The changes included within the revised ACoP and supporting Technical Guidance documents may not be dramatic but there are subtle differences that Duty Holders need to be aware of. No matter how large or small the organisation, the HSE ACoP is a document that duty holders must be compliant with.

Goodwater welcomes the introduction of the revised ACoP and new guidance and believes that the enhanced clarity they contain will help employers to better meet their requirements under the Approved Code of Practice.
