Legionnaires’ disease – the importance of properly monitoring water

Understanding Legionnaires’ disease and the risks associated with it

If you are an employer, or someone in control of premises, including landlords, you must understand the health risks associated with legionella. Duties under the Health and Safety at Work etc Act 1974 (HSWA) extend to risks from legionella bacteria, which may arise from work activities. The Management of Health and Safety at Work Regulations (MHSWR) provide a broad framework for controlling health and safety at work.

More specifically, the Control of Substances Hazardous to Health Regulations 2002 (COSHH) provide a framework of actions designed to assess, prevent or control the risk from bacteria like Legionella and take suitable precautions. The Approved Code of Practice: Legionnaires’ disease: The control of Legionella bacteria in water systems (L8) contains practical guidance on how to manage and control the risks in your system.

As an employer, or a person in control of the premises, YOU are responsible for health and safety and need to take the right precautions to reduce the risks of exposure to legionella. You must understand how to:

  • identify and assess sources of risk
  • manage any risks
  • prevent or control any risks
  • keep and maintain the correct records
  • carry out any other duties you may have

Consequences of incorrectly monitoring potential risks

Neglecting health regulations can have devastating consequences. A notable instance of this was the horrific outbreak of Legionnaires in Scotland 2012, in which four people died and there were 92 cases of Legionnella detected. It was the worst outbreak of Legionnella for 10 years. The source of the infection is believed to have come from cooling towers. More than 40 families have been affected by the Edinburgh disaster, and are now to sue two companies believed to be responsible.

 

How can instances like this be avoided?

To minimize the risk of legionella water temperature must be properly regulated and monitored. Testo provide a number of instruments to help make sure water temperature is correctly monitored in the hope there are no more Legionella related disasters.
