Watermark Compliance Ltd
Legionella Risk Assessment
Who needs a Legionella Risk Assessment?
COSHH regulations and the Health & Safety at Work Act require employers to make suitable and sufficient assessment of the risk from any work liable to expose employees to any substance hazardous to health, before that work is carried out. ACoP L8 (Fourth Edition) “The control of legionella bacteria in water systems” states there is a reasonably foreseeable risk of exposure to legionella bacteria in:
-
cooling towers, evaporative condensers and dry/wet cooling systems (adiabatic coolers);
-
hot and cold water systems;
-
spa pools;
-
other plant and systems containing water that can create an increase the risk of legionella during operation or when being maintained.
In order to comply with ACoP L8 all the above systems require a risk assessment, therefore the vast majority of employers will require one, most having water systems of some description.
Whilst legionella risk assessments can be carried out by the employer, in order to comply they should be carried out by someone competent and trained to do so, therefore, in the vast majority of cases they are carried out by an external specialist companies, such as Watermark Compliance Ltd.

How often do I need to do a legionella risk assessment?
ACoP L8 states that you need to review the assessment regularly and specifically when there is reason to believe that the original risk assessment may no longer be valid. This may result from:
-
changes to the water system and its use;
-
changes to the use of the building in which the water system is installed;
-
the availability of new information about the risks or control measures;
-
the results of checks indicating that control measures are no longer effective;
-
changes to key personnel;
-
a case of Legionnaires’ disease/Legonellosis associated with the system.
