The above will be repeated at 6 and 12 monthly intervals throughout the period of the 5-year contract. The Consultant’s checks at 6 and 12 months are not intended to replace those carried out by the Premises Responsible Person/Nominated Legionella Coordinator but are in addition to them.
Premises managers should, as part of their regular health and safety inspections, review the web-based portal and check that it is being used in accordance with the prescribed procedures, recording that they have done so.
The record of the Legionella water risk assessment is a living document that must be reviewed to ensure it remains up to date. The assessment will be regularly reviewed as stated above, however it will also need to be reviewed specifically whenever there is reason to suspect it is no longer valid. An indication of when to review the assessment and what to consider should be recorded, is as follows:
-
If there are changes to the water system or its use.
-
If there are changes to the use of the building in which the water system is installed.
-
If there is new information about risks or control measures.
-
The results of checks indicate that the control measures are no longer effective.
-
There are changes to key personnel on site for example the Premises Responsible Person or the Legionella Co-ordinator.
-
A case of legionnaires’ disease or legionellosis is associated with the system.
