Legal Requirement for Legionella Risk Assessment

The Safety, Health and Welfare at Work Act 2005 requires employers to identify hazards and assess risks. For most buildings that includes the hot and cold water system, where legionella bacteria can grow. Building owners, facility managers and managing agents should also be clear about who is responsible for the water system. Read our guide on who is responsible for legionella control.

  • Safety, Health and Welfare at Work Act 2005 (No.10 of 2005)
  • Safety, Health and Welfare at Work (Biological Agents) Regulations 2013 (S.I. No.572 of 2013.)
  • Safety, Health and Welfare at Work (General Application) Regulations 2007 (S.I. No.299 of 2007)
  • Safety, Health and Welfare at Work (Chemical Agents) Regulations, 2001 (S.I. No.619 of 2001)

A systematic risk management approach, as set out in the HPSC National Guidelines for the Control of Legionellosis in Ireland, should be adopted to prevent and control the risk of exposure to legionella bacteria. The Health and Safety Authority also publishes information on Legionnaires’ disease.

A legionella risk assessment looks at the risk of legionella growth in the water systems on your site. Risk assessments are completed with reference to relevant Irish legislation and guidance, including:

  • The Health Protection Surveillance Centre National Guidelines for the Control of Legionellosis in Ireland (2009).
  • Health and Safety Authority information on Legionnaires' disease.

Legionella Risk Assessment provides a concise report that includes a documented summary of all plants, photographic evidence, an assessment of current policies and procedures, water sampling results, schematics of water systems, and an asset register if needed. Risk assessments should, in accordance with guidelines, include the following:

  • Identification and assessment of potential risk sources;
  • Determine the best means of preventing or controlling the risk;
  • Guide the implementation, management, and monitoring of precautions;
  • Identify and document the responsibilities of all managers
