Legionella Risks During the Coronavirus Pandemic

Legionella Risks During the Coronavirus Pandemic

13 April 2021

Many businesses and premises have been closed, or had reduced occupancy, for extended periods of time during lockdown. During closure, water system stagnation can occur due to lack of use, increasing the risks of Legionnaires' disease. It is therefore essential that risks are identified and controlled.

Legionellosis is a collective term for diseases caused by legionella bacteria including the most serious Legionnaires' disease. It is a potentially fatal form of pneumonia and everyone is susceptible to infection.

HSE has put together guidance on best practice when you reinstate a water system or start using it again, including some types of air conditioning units.

Bacteria may also have accumulated in water pipes, taps and hoses and therefore water must be run through to waste for at least five minutes before using the water to make up any cleaning solutions.

Many dosing units and water systems will need to be cleaned and maintained after long periods of inactivity. Below you will find our guidance for catering and hospitality settings.
