BS 8580 was first published in 2010 and provided a guide to risk assessments performed with the intention to identify and manage risks associated with Legionnaires disease.
The standard has been renamed (from BS 8580 to BS 8580-1) and revised to align it with the HSE ACoP L8 (4th edition) (Approval code of Practice) and associated guidance documents such as HSG 274 (Legionnaires' disease – Technical guidance) which were revised in 2014.
The revision also takes into account HSG 282 - Control of legionella and other infectious agents in spa-pools – a system that was published in January 2017. There was also a need to update references within the standard.
