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.

  • Workplace Air Monitoring COSHH Regulations employers must ensure that workplace air monitoring is undertaken to ensure adequate control. Workplace Exposure Limits (WELs) for airborne contaminants are listed in the HSE Guidance Document (EH40).
  • Respiratory Protection Equipment (RPE) - Face Fit Testing In situations where adequate control of exposure to airborne substances cannot be achieved in line with Approved Codes of Practice (ACoPs) supporting the COSHH Regulations, the Control of Lead at Work Regulations (CLAW), Control of Asbestos Regulations (CAR) and Ionising Radiation Regulations, employers must provide suitable respiratory protection equipment (RPE).
  • Noise Monitoring It is an employer’s responsibility to comply with both The Control of Noise at Work Regulations and environmental guidelines for external noise pollution.
