CD258 – Consultation on Legionnaires' disease: The control of legionella bacteria in water systems (L8)

This Consultative Document (CD258) sets out proposals from HSE to publish an updated Approved Code of Practice (ACOP) on Legionnaire’s disease: ‘The control of legionella bacteria in water systems’. 

The consultation provides an opportunity to comment on whether the draft ACOP text provides legal clarification and proportionate advice in low risk scenarios. The accompanying guidance provides advice on achieving compliance, and information of a general nature including explanation of the requirements of the law, specific technical information or references to further sources of information.

The revised ACOP gives practical advice on the legal requirements of the Health and Safety at Work etc Act 1974 and the Control of Substances Hazardous to Health Regulations 2002 (COSHH) and applies to the risk from exposure to legionella bacteria and includes information of a general nature including explanation of the requirements of law.

The key changes include:

  • Some guidance assigned ACOP status to clarify legal requirements where there is an accepted Industry method of compliance.
  • Some text changed from ACOP to guidance status where the changes do not impact on practical compliance requirements.
  • Simplified terminology.
  • Proportionality in low risk scenarios emphasised.
