Legionella Update: New Guidance HSG274 Part 2 Published – what are the main changes?

6th June 2014

The Health & Safety Executive (HSE) has recently updated the safety rules dealing with the control of Legionella risks with an extensive overhaul of their Approved Code of Practice (ACOP) L8, together with a brand new guidance document covering the management of Legionnaires’ disease and the control of Legionella bacteria in water systems.

The new guidance document, HSG274, is split into three parts:

  • Part 1 – The control of Legionella bacteria in evaporative cooling systems.
  • Part 2 – The control of Legionella bacteria in hot and cold water systems.
  • Part 3 – The control of Legionella bacteria in other risk systems.

HSG274 Parts 1 and 3 were published in late 2013, however Part 2 was more recently published in April 2014.

Hot and cold water systems, covered by HSG274 Part 2, are by far the most common form of water system presenting a Legionella risk.

The S2 Partnership has put together a briefing note to explain the changes to HSG274 Part 2 and the impacts for those responsible for controlling Legionella risks. For your copy, click here.
