Revised British Standard on Legionella risk assessment

14 February 2019


BSI, the business standards company, has released British Standard BS 8580-1:2019 Water quality, risk assessments for Legionella control – Code of practice. This is a significant revision to the 2010 British Standard providing further guidelines for assessing water quality and the risk of Legionnaires disease.

The standard gives recommendations and guidance on the assessment of the risk of Legionellosis presented by artificial water systems. Legionellosis is a collective term for diseases caused by bacteria of the genus Legionella, an opportunist pathogen which normally inhabits warm, moist or aquatic environments. The most serious and potentially fatal is Legionnaires’ disease.

David Fatscher, head of sustainability at BSI, said: “We shouldn’t underestimate the risk Legionnaires’ disease poses to society today, therefore having updated guidance and recommendations for its prevention is as important as ever. This revised standard aims to enable anyone with responsibility for the health and safety of others in public premises, across the spectrum from the workplace to hospitals, to undertake the necessary risk assessments and adopt adequate prevention measures.”
