Prevent Legionella In Buildings During Lockdown or In Normal Operation

Risk Assessments and Permanent Legionella Prevention Solutions

During these challenging times, many buildings are currently not in use such as offices, schools, museums, sports centres, and holiday parks. Water services that have low use and stagnant areas have an increased potential risk for legionella growth. On the other hand, hospitals, nursing homes, and residential care are in operation and are 100% focused on the health and care of their patients. In both situations (lockdown or not lockdown building) extra precautions must be undertaken to protect their exposure to Legionella bacteria.

Legionella Bacteria in London

Legionella bacteria may grow in any system containing water, such as cooling towers and hot and cold water services. They survive low temperatures and thrive at temperatures between 20°C-45°C, especially where there is scale, corrosion and high microbiological load.

Water outlets are a risk factor for Legionella Bacteria

Several local authorities provide technical guidance for legionella control, eg. the UK Health and Safety Executive (HSE) guidance: hse.gov.uk/legionnaires/

Comply with legal duties

Water is used in various ways in today's factories and offices, and each use should be risk assessed as advocated by the local authorities. In order to comply with their legal duties in controlling legionella, the owners of the premises have a legal responsibility to:

  • Identify and assess sources of risk
  • Prepare a scheme for preventing and controlling the risk
  • Implement, manage, and monitor precautions and control measures, such as frequently opening outlets for offices and sites which are not in use.
  • Keep records of the precautions/control measures
  • Appoint a person to have managerial responsibility
