Assessing the risk of a Legionnaires outbreak

An outbreak of Legionnaires disease puts people’s lives at risk, and leaves the buildings and associated organisations responsible open to legal action, fines and reputation damage. In buildings with a high footfall of people such as hospitals, schools, commercial and tenanted properties, a legionella risk assessment must be completed.

Legionella can be a particular problem in cooling towers and HVAC systems, but all sanitation and general plumbing should be checked as the bacteria can grow in any location where water is present.

A legionella risk assessment forms part of the compliance criteria for ACoP L8 (Approved Code of Practice L8 2013 – The Control of Legionella Bacteria in Water Systems). Guidance for legionella control is also outlined in HSG274.
