Approved Code of Practice and guidance on regulations
L8 (Fourth edition) Published 2013

This book is aimed at dutyholders, including employers, those in control of premises and those with health and safety responsibilities for others, to help them comply with their legal duties in relation to legionella. These include identifying and assessing sources of risk, preparing a scheme to prevent or control risk, implementing, managing and monitoring precautions, keeping records of precautions and appointing a manager to be responsible for others.

This fourth edition of the ACOP and guidance on regulations contains revisions to simplify and clarify the text. The main changes are removing Part 2, the technical guidance, which is published separately as HSG274 and giving the following issues ACOP status:

  • Risk assessment
  • The specific role of an appointed competent person, known as the ‘responsible person’
  • The control scheme
  • Review of control measures
  • Duties and responsibilities of those involved in the supply of water systems

The guidance gives practical advice on the legal requirements of the Health and Safety at Work etc Act 1974, the Control of Substances Hazardous to Health Regulations 2002 concerning the risk from exposure to legionella and guidance on compliance with the relevant parts of the Management of Health and Safety at Work Regulations 1999.

The guidance is in 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 (Interim guidance)
Part 3: The control of legionella bacteria in other risk systems

The complete hard copy edition of HSG274, including revised guidance on hot and cold water systems, and a revised online version of Part 2, will be published in 2014.
