The COSHH Regulations and HSE Approved Code of Practice and Guidance Document: Legionnaires' Disease states that employers have a duty to take suitable precautions to prevent or control the risk of exposure to legionella.

Legionnaires' disease is a potentially fatal form of pneumonia caused by legionella bacteria which can contaminate and grow in purpose-built water systems such as cooling towers, evaporative condensers and hot and cold water systems.

Employers must:

  • Identify and assess sources of risk
  • Prepare a written scheme for preventing or controlling the risk
  • Implement, manage and monitor precautions
  • Keep records of the precautions
  • Appoint a competent person with sufficient knowledge of the installation to maintain required standards to comply with the law

A Legionella Risk Assessment includes:

  • A visual inspection of water systems
  • The measurement of water temperatures
  • An evaluation of legionella control
  • The production of appropriate schematic diagrams to show the water system layout

All the necessary areas will be addressed to ensure compliance with theCode of Practice including recommendations for future control measuresand management of the risks.
