Legionella Risk Assessment

By May 21, 2021June 14th, 2021No Comments

Since the publication of the fourth edition of the Approved Code of Practice L8 in November 2013 there is a good deal of confusion and misunderstanding among many Legionella Services suppliers as to how frequently a risk assessment must be reviewed.

Oakleaf have long established that a review of the risk assessment is not a review of the document submitted to the client, but a review of the risk itself and the issue of a new document taking into account the findings of the previous risk assessment. The actual review frequency of the risk will be determined by the consultant performing the assessment. This ensures that the risk assessment remains as up to date as necessary depending on the risk. For most reports.

Performing a ‘Desktop Risk Review’ without ever surveying the site has never been acceptable or appropriate and must never be completed.

It is a requirement of the Approved Code of Practice L8 (fourth edition 2013) that all systems require a Legionella Risk Assessment without exception. It is still possible that a system or building may pose negligible risk and only a limited number of measures may be necessary following the risk assessment.

What is Legionella?

Legionnaires’ disease is a severe form of pneumonia — lung inflammation usually caused by infection. It’s caused by a bacterium known as legionella. Most people catch Legionnaires’ disease by inhaling the bacteria from water or soil.
